The Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra.
Characteristics of Tundra:
Extremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations
Arctic tundra is located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga. The arctic is known for its cold, desert-like conditions. The growing season ranges from 50 to 60 days. The average winter temperature is -34° C (-30° F), but the average summer temperature is 3-12° C (37-54° F) which enables this biome to sustain life. Rainfall may vary in different regions of the arctic. Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches). Soil is formed slowly. A layer of permanently frozen subsoil called permafrost exists, consisting mostly of gravel and finer material. When water saturates the upper surface, bogs and ponds may form, providing moisture for plants. There are no deep root systems in the vegetation of the arctic tundra, however, there are still a wide variety of plants that are able to resist the cold climate. There are about 1,700 kinds of plants in the arctic and subarctic, and these include: low shrubs, sedges, reindeer mosses, liverworts, and grasses, 400 varieties of flowers crustose and foliose lichen.
All of the plants are adapted to sweeping winds and disturbances of the soil. Plants are short and group together to resist the cold temperatures and are protected by the snow during the winter. They can carry out photosynthesis at low temperatures and low light intensities. The growing seasons are short and most plants reproduce by budding and division rather than sexually by flowering. The fauna in the arctic is also diverse:
Herbivorous mammals: lemmings, voles, caribou, arctic hares and squirrels.
Carnivorous mammals: arctic foxes, wolves, and polar bears.
Migratory birds: ravens, snow buntings, falcons, loons, ravens, sandpipers, terns, snow birds, and various species of gulls.
Insects: mosquitoes, flies, moths, grasshoppers, blackflies and arctic bumble bees.
Fish: cod, flatfish, salmon, and trout.
Animals are adapted to handle long, cold winters and to breed and raise young quickly in the summer. Animals such as mammals and birds also have additional insulation from fat. Many animals hibernate during the winter because food is not abundant. Another alternative is to migrate south in the winter, like birds do. Reptiles and amphibians are few or absent because of the extremely cold temperatures. Because of constant immigration and emigration, the population continually oscillates.
Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. The growing season is approximately 180 days. The
night time temperature is usually below freezing. Unlike the arctic tundra, the soil in the alpine is well drained. The plants are very similar to those of the arctic ones and include:
tussock grasses, dwarf trees, small-leafed shrubs, and heaths.
Animals living in the alpine tundra are also well adapted:
Mammals: pikas, marmots, mountain goats, sheep, elk.
Birds: grouse like birds.
Insects: springtails, beetles, grasshoppers, butterflies.
|Cold regions include
arctic and subarctic areas and areas immediately adjoining them. You can
classify about 48 percent of the northern hemisphere's total landmass as
a cold region due to the influence and extent of air temperatures. Ocean
currents affect cold weather and cause large areas normally included in
the temperate zone to fall within the cold regions during winter
periods. Elevation also has a marked effect on defining cold regions. Within the cold weather regions, you
may face two types of cold weather environments wet or dry. Knowing in
which environment your area of operations falls will affect planning and
execution of a cold weather operation.
Wet cold weather conditions exist when the average temperature in a 24-hour period is -10C or above. Characteristics of this condition are freezing during the colder night hours and thawing during the day. Even though the temperatures are warmer during this condition, the terrain is usually very sloppy due to slush and mud. You must concentrate on protecting yourself from the wet ground and from freezing rain or wet snow.
Dry cold weather conditions exist when the average temperature in a 24-hour period remains below -10C. Even though the temperatures in this condition are much lower than normal, you do not have to contend with the freezing and thawing. In these conditions, you need more layers of inner clothing to protect you from temperatures as low as -60C. Extremely hazardous conditions exist when wind and low temperature combine.
Wind chill increases the hazards in cold regions. Wind chill is the effect of moving air on exposed flesh. For instance, with a 28kph (15 knot) wind and a temperature of -10C, the equivalent wind chill temperature is -23C. Remember, even when there is no wind, you will create the equivalent wind by skiing, running, being towed on skis behind a vehicle, working around aircraft that produce wind blasts.
|You must not only have enough
clothing to protect you from the cold, you must also know how to
maximize the warmth you get from it. For example, always keep your head
covered. You can lose 40 to 45 percent of body heat from an unprotected
head and even more from the unprotected neck, wrist, and ankles. These
areas of the body are good radiators of heat and have very little
insulating fat. The brain is very susceptible to cold and can stand the
least amount of cooling. Because there is much blood circulation in the
head, most of which is on the surface, you can lose heat quickly if you
do not cover your head.
There are four basic principles to follow to keep warm. An easy way to remember these basic principles is to use the word COLD;
C - Keep clothing clean. This principle is always important for sanitation and comfort. In winter, it is also important from the standpoint of warmth. Clothes matted with dirt and grease lose much of their insulation value. Heat can escape more easily from the body through the clothing's crushed or filled up air pockets.
O - Avoid overheating. When you get too hot, you sweat and your clothing absorbs the moisture. This affects your warmth in two ways: dampness decreases the insulation quality of clothing, and as sweat evaporates, your body cools. Adjust your clothing so that you do not sweat. Do this by partially opening your parka or jacket, by removing an inner layer of clothing, by removing heavy outer mittens, or by throwing back your parka hood or changing to lighter headgear. The head and hands act as efficient heat dissipaters when overheated.
L - Wear clothes loose and in layers. Wearing tight clothing and footgear restricts blood circulation and invites cold injury. It also decreases the volume of air trapped between the layers, reducing its insulating value. Several layers of lightweight clothing are better than one equally thick layer of clothing, because the layers have dead-air space between them. The dead-air space provides extra insulation. Also, layers of clothing allow you to take off or add clothing layers to prevent excessive sweating or to increase warmth.
D - Keep clothing dry. In cold temperatures, your inner layers of clothing can become wet from sweat and your outer layer, if not water repellent, can become wet from snow and frost melted by body heat. Wear water repellent outer clothing, if available. It will shed most of the water collected from melting snow and frost. Before entering a heated shelter, brush off the snow and frost. Despite the precautions you take, there will be times when you cannot keep from getting wet. At such times, drying your clothing may become a major problem. On the march, hang your damp mittens and socks on your rucksack. Sometimes in freezing temperatures, the wind and sun will dry this clothing. You can also place damp socks or mittens, unfolded, near your body so that your body heat can dry them. In a campsite, hang damp clothing inside the shelter near the top, using drying lines or improvised racks. You may even be able to dry each item by holding it before an open fire. Dry leather items slowly. If no other means are available for drying your boots, put them between your sleeping bag shell and liner. Your body heat will help to dry the leather.
A heavy, down-lined sleeping bag is a valuable piece of survival gear in cold weather. Ensure the down remains dry. If wet, it loses a lot of its insulation value. If you do not have a sleeping bag, you can make one out of parachute cloth or similar material and natural dry material, such as leaves, pine needles, or moss. Place the dry material between two layers of the material. Other important survival items are a knife; waterproof matches in a waterproof container, preferably one with a flint attached; a durable compass; map; watch; waterproof ground cloth and cover; flashlight; binoculars; dark glasses; fatty emergency foods; food gathering gear; and signalling items. Remember, a cold weather environment can be very harsh. Give a good deal of thought to selecting the right equipment for survival in the cold. If unsure of an item you have never used, test it in an "overnight backyard" environment before venturing further. Once you have selected items that are essential for your survival, do not lose them after you enter a cold weather environment. When you are healthy, your inner core temperature (torso temperature) remains almost constant at 37 degrees C (98.6 degrees F). Since your limbs and head have less protective body tissue than your torso, their temperatures vary and may not reach core temperature. Your body has a control system that lets it react to temperature extremes to maintain a temperature balance. There are three main factors that affect this temperature balance--heat production, heat loss, and evaporation. The difference between the body's core temperature and the environment's temperature governs the heat production rate. Your body can get rid of heat better than it can produce it. Sweating helps to control the heat balance. Maximum sweating will get rid of heat about as fast as maximum exertion produces it. Shivering causes the body to produce heat. It also causes fatigue that, in turn, leads to a drop in body temperature. Air movement around your body affects heat loss. It has been calculated that a naked man exposed to still air at or about 0 degrees C can maintain a heat balance if he shivers as hard as he can. However, he can't shiver forever. It has also been calculated that a man at rest wearing the maximum arctic clothing in a cold environment can keep his internal heat balance during temperatures well below freezing. To withstand really cold conditions for any length of time, however, he will have to become active or shiver.
|Although washing yourself may be impractical and uncomfortable in a cold environment, you must do so. Washing helps prevent skin rashes that can develop into more serious problems. In some situations, you may be able to take a snow bath. Take a handful of snow and wash your body where sweat and moisture accumulate, such as under the arms and between the legs, and then wipe yourself dry. If possible, wash your feet daily and put on clean, dry socks. Change your underwear at least twice a week. If you are unable to wash your underwear, take it off, shake it, and let it air out for an hour or two. If you are using a previously used shelter, check your body and clothing for lice each night. If your clothing has become infested, use insecticide powder if you have any. Otherwise, hang your clothes in the cold, then beat and brush them. This will help get rid of the lice, but not the eggs. If you shave, try to do so before going to bed. This will give your skin a chance to recover before exposing it to the elements.|
|Hypothermia is the lowering of the
body temperature at a rate faster than the body can produce heat. Causes
of hypothermia may be general exposure or the sudden wetting of the body
by falling into a lake or spraying with fuel or other liquids. The initial symptom is shivering. This
shivering may progress to the point that it is uncontrollable and
interferes with an individual's ability to care for himself. This begins
when the body's core (rectal) temperature falls to about 35.5C (96F).
When the core temperature reaches 35 to 32C (95 to 90F), sluggish
thinking, irrational reasoning, and a false feeling of warmth may occur.
Core temperatures of 32 to 30C (90 to 86F) and below result in muscle
rigidity, unconsciousness, and barely detectable signs of life. If the
victim's core temperature falls below 25C (77F), death is almost
certain. To treat hypothermia, rewarm the entire body.
If there are means available, rewarm the person by first immersing the
trunk area only in warm water of 37.7 to 43.3C (100 to 110F).
Rewarming the total body in a warm water bath should be done only in a hospital environment because of the increased risk of cardiac arrest and rewarming shock. One of the quickest ways to get heat to the inner core is to give warm water enemas. Such an action, however, may not be possible in a survival situation. Another method is to wrap the victim in a warmed sleeping bag with another person who is already warm; both should be naked. The individual placed in the sleeping bag with victim could also become a hypothermia victim if left in the bag too long. If the person is conscious, give him hot, sweetened fluids. One of the best sources of calories is honey or dextrose; if unavailable, use sugar, cocoa, or a similar soluble sweetener. Do not force an unconscious person to drink. There are two dangers in treating hypothermia; rewarming too rapidly and after drop. Rewarming too rapidly can cause the victim to have circulatory problems, resulting in heart failure. After drop is the sharp body core temperature drop that occurs when taking the victim from the warm water. Its probable muse is the return of previously stagnant limb blood to the core (inner torso) area as recirculation occurs. Concentrating on warming the core area and stimulating peripheral circulation will lessen the effects of after drop. Immersing the torso in a warm bath, if possible, is the best treatment.
|This injury is the result of frozen
tissues. Light frostbite involves only the skin that takes on a dull
whitish pallor. Deep frostbite extends to a depth below the skin. The
tissues become solid and immovable. Your feet, hands, and exposed facial
areas are particularly vulnerable to frostbite. The best frostbite prevention, when you are
with others, is to use the buddy system. Check your buddy's face often
and make sure that he checks yours. If you are alone, periodically cover
your nose and lower part of your face with your mittened hand. The following pointers will aid you in keeping
warm and preventing frostbite when it is extremely cold or when you have
less than adequate clothing:
Face; Maintain circulation by twitching and wrinkling the skin on your face making faces. Warm with your hands.
Ears; Wiggle and move your ears. Warm with your hands.
Hands; Move your hands inside your gloves. Warm by placing your hands close to your body.
Feet; Move your feet and wiggle your toes inside your boots. A loss of feeling in your hands and feet is a sign of frostbite. If you have lost feeling for only a short time, the frostbite is probably light. Otherwise, assume the frostbite is deep. To rewarm a light frostbite, use your hands or mittens to warm your face and ears. Place your hands under your armpits. Place your feet next to your buddy's stomach. A deep frostbite injury, if thawed and refrozen, will cause more damage than a nonmedically trained person can handle.
|Exposed skin can become sunburned
even when the air temperature is below freezing. The sun's rays reflect
at all angles from snow, ice, and water, hitting sensitive areas of
skin; lips, nostrils, and eyelids. Exposure to the sun results in
sunburn more quickly at high altitudes than at low altitudes. Apply
sunburn cream or lip salve to your face when in the sun. The reflection of the sun's ultraviolet rays
off a snow-covered area causes this condition. The symptoms of snow
blindness are a sensation of grit in the eyes, pain in and over the eyes
that increases with eyeball movement, red and teary eyes, and a headache
that intensifies with continued exposure to light. Prolonged exposure to
these rays can result in permanent eye damage. To treat snow blindness,
bandage your eyes until the symptoms disappear. You can prevent snow blindness by wearing
sunglasses. If you don't have sunglasses, improvise. Cut slits in a
piece of cardboard, thin wood, tree bark, or other available material.
Putting soot under your eyes will help reduce shine and glare. It is very important to relieve yourself when
needed. Do not delay because of the cold condition. Delaying relieving
yourself because of the cold, eating dehydrated foods, drinking too
little liquid, and irregular eating habits can cause you to become
constipated. Although not disabling, constipation can cause some
discomfort. Increase your fluid intake to at least 2 litres above your
normal 2 to 3 litres daily intake and, if available, eat fruit and other
foods that will loosen the stool. Insect bites can become infected through
constant scratching. Flies can carry various disease-producing germs. To
prevent insect bites, use insect repellent, netting, and wear proper
clothing. Avoid travelling during a blizzard. Take care when crossing thin ice. Distribute
your weight by lying flat and crawling. Cross streams when the water level is lowest.
Normal freezing and thawing action may cause a stream level to vary as
much as 2 to 2.5mtrs per day. This variance may occur any time during
the day, depending on the distance from a glacier, the temperature, and
the terrain. Consider this variation in water level when selecting a
campsite near a stream.
Consider the clear arctic air. It makes estimating distance difficult. You more frequently underestimate than overestimate distances. Do not travel in whiteout conditions. The lack of contrasting colours makes it impossible to judge the nature of the terrain. Always cross a snow bridge at right angles to the obstacle it crosses. Find the strongest part of the bridge by poking ahead of you with a pole or ice axe. Distribute your weight by crawling or by wearing snowshoes or skis. Make camp early so that you have plenty of time to build a shelter. Consider frozen or unfrozen rivers as avenues of travel. However, some rivers that appear frozen may have soft, open areas that make travel very difficult or may not allow walking, skiing, or sledding. Use snowshoes if you are travelling over snow-covered terrain. Snow 30 or more centimetres deep makes travelling difficult. If you do not have snowshoes, make a pair using willow, strips of cloth, leather, or other suitable material. It is almost impossible to travel in deep snow without snowshoes or skis. Travelling by foot leaves a well-marked trail for any pursuers to follow. If you must travel in deep snow, avoid snow-covered streams. The snow, which acts as an insulator, may have prevented ice from forming over the water. In hilly terrain, avoid areas where avalanches appear possible. Travel in the early morning in areas where there is danger of avalanches. On ridges, snow gathers on the lee side in overhanging piles called cornices. These often extend far out from the ridge and may break loose if stepped on.
|Your environment and the
equipment you carry with you will determine the type of shelter you can
build. You can build shelters in wooded areas, open country, and barren
areas. Wooded areas usually provide the best location, while barren
areas have only snow as building material. Wooded areas provide timber
for shelter construction, wood for fire, concealment from observation,
and protection from the wind. In extreme cold, do not use metal, such as
an aircraft fuselage, for shelter. The metal will conduct away from the
shelter what little heat you can generate. Shelters made from ice or snow usually
require tools such as ice axes or saws. You must also expend much time
and energy to build such a shelter. Be sure to ventilate an enclosed
shelter, especially if you intend to build a fire in it. Always block a
shelter's entrance, if possible, to keep the heat in and the wind out.
Use a rucksack or snow block. Construct a shelter no larger than needed.
This will reduce the amount of space to heat. A fatal error in cold
weather shelter construction is making the shelter so large that it
steals body heat rather than saving it. Keep shelter space small. Never sleep directly on the ground.
Lay down some pine boughs, grass, or other insulating material to keep
the ground from absorbing your body heat. Never fall asleep without
turning out your stove or lamp. Carbon monoxide poisoning can result
from a fire burning in an unventilated shelter. Carbon monoxide is a
great danger. It is colourless and odourless. Any time you have an open
flame, it may generate carbon monoxide. Always check your ventilation.
Even in a ventilated shelter, incomplete combustion can cause carbon
monoxide poisoning. Usually, there are no symptoms. Unconsciousness and
death can occur without warning. Sometimes, however, pressure at the
temples, burning of the eyes, headache, pounding pulse, drowsiness, or
nausea may occur. The one characteristic, visible sign of carbon
monoxide poisoning is a cherry red colouring in the tissues of the lips,
mouth, and inside of the eyelids. Get into fresh air at once if you have
any of these symptoms. There are several types of
field-expedient shelters you can quickly build or employ. Many use snow
Snow Cave Shelter
The snow cave shelter is a most effective shelter because of the insulating qualities of snow. Remember that it takes time and energy to build and that you will get wet while building it. First, you need to find a drift about 3 meters deep into which you can dig. While building this shelter, keep the roof arched for strength and to allow melted snow to drain down the sides. Build the sleeping platform higher than the entrance. Separate the sleeping platform from the snow cave's walls or dig a small trench between the platform and the wall. This platform will prevent the melting snow from wetting you and your equipment. This construction is especially important if you have a good source of heat in the snow cave. Ensure the roof is high enough so that you can sit up on the sleeping platform. Block the entrance with a snow block or other material and use the lower entrance area for cooking. The walls and ceiling should be at least 30 centimetres thick. Install a ventilation shaft. If you do not have a drift large enough to build a snow cave, you can make a variation of it by piling snow into a mound large enough to dig out.
Snow Trench Shelter
The idea behind this shelter is to get you below the snow and wind level and use the snow's insulating qualities. If you are in an area of compacted snow, cut snow blocks and use them as overhead cover. If not, you can use a poncho or other material. Build only one entrance and use a snow block or rucksack as a door.
Snow Block and Parachute Shelter
Use snow blocks for the sides and parachute material for overhead cover. If snowfall is heavy, you will have to clear snow from the top at regular intervals to prevent the collapse of the parachute material.
Snow House or Igloo
In certain areas, the natives frequently use this type of shelter as hunting and fishing shelters. They are efficient shelters but require some practice to make them properly. Also, you must be in an area that is suitable for cutting snow blocks and have the equipment to cut them (snow saw or knife).
|Fire is especially important in
cold weather. It not only provides a means to prepare food, but also to
get warm and to melt snow or ice for water. It also provides you with a
significant psychological boost by making you feel a little more secure
in your situation. All wood will burn, but some types of wood
create more smoke than others. For instance, coniferous trees that
contain resin and tar create more and darker smoke than deciduous trees.
There are few materials to use for fuel in the
high mountainous regions of the arctic. You may find some grasses and
moss, but very little. The lower the elevation, the more fuel available.
You may find some scrub willow and small, stunted spruce trees above the
tree line. On sea ice, fuels are seemingly nonexistent. Driftwood or
fats may be the only fuels available to a survivor on the barren
coastlines in the arctic and subarctic regions.
Abundant fuels within the tree line are;
Spruce trees are common in the interior regions. As a conifer, spruce makes a lot of smoke when burned in the spring and summer months. However, it burns almost smoke-free in late fall and winter.
The tamarack tree is also a conifer. It is the only tree of the pine family that loses its needles in the fall. Without its needles, it looks like a dead spruce, but it has many knobby buds and cones on its bare branches. When burning, tamarack wood makes a lot of smoke and is excellent for signalling purposes.
Birch trees are deciduous and the wood burns hot and fast, as if soaked with oil or kerosene. Most birches grow near streams and lakes, but occasionally you will find a few on higher ground and away from water.
Willow and alder grow in arctic regions, normally in marsh areas or near lakes and streams. These woods burn hot and fast without much smoke.
Dried moss, grass, and scrub willow are other materials you can use for fuel. These are usually plentiful near streams in tundras (open, treeless plains). By bundling or twisting grasses or other scrub vegetation to form a large, solid mass, you will have a slower burning, more productive fuel.
If fuel or oil is available from a wrecked vehicle or downed aircraft, use it for fuel. Leave the fuel in the tank for storage, drawing on the supply only as you need it. Oil congeals in extremely cold temperatures, therefore, drain it from the vehicle or aircraft while still warm if there is no danger of explosion or fire. If you have no container, let the oil drain onto the snow or ice. Scoop up the fuel as you need it. Do not expose flesh to petroleum, oil, and lubricants in extremely cold temperatures. The liquid state of these products is deceptive in that it can cause frostbite. Some plastic products, such as MRE spoons, helmet visors, visor housings, aid foam rubber will ignite quickly from a burning match. They will also burn long enough to help start a fire. For example, a plastic spoon will burn for about 10 minutes. In cold weather regions, there are some hazards in using fires, whether to keep warm or to cook. For example fires have been known to burn underground, resurfacing nearby. Therefore, do not build a fire too close to a shelter. In snow shelters, excessive heat will melt the insulating layer of snow that may also be your camouflage. A fire inside a shelter lacking adequate ventilation can result in carbon monoxide poisoning. A person trying to get warm or to dry clothes may become careless and burn or scorch his clothing and equipment. Melting overhead snow may get you wet, bury you and your equipment, and possibly extinguish your fire. In general, a small fire and some type of stove is the best combination for cooking purposes. A hobo stove is particularly suitable to the arctic. It is easy to make out of a tin can, and it conserves fuel. A bed of hot coals provides the best cooking heat. Coals from a crisscross fire will settle uniformly. Make this type of fire by crisscrossing the firewood. A simple crane propped on a forked stick will hold a cooking container over a fire. For heating purposes, a single candle provides enough heat to warm an enclosed shelter. A small fire about the size of a man's hand is ideal for use in enemy territory. It requires very little fuel, yet it generates considerable warmth and is hot enough to warm liquids.
|There are many sources of water in the arctic and subarctic. Your location and the season of the year will determine where and how you obtain water. Water sources in arctic and subarctic regions are more sanitary than in other regions due to the climatic and environmental conditions. However, always purify the water before drinking it. During the summer months, the best natural sources of water are freshwater lakes, streams, ponds, rivers, and springs. Water from ponds or lakes may be slightly stagnant, but still usable. Running water in streams, rivers, and bubbling springs is usually fresh and suitable for drinking. The brownish surface water found in a tundra during the summer is a good source of water. However, you may have to filter the water before purifying it. You can melt freshwater ice and snow for water. Completely melt both before putting them in your mouth. Trying to melt ice or snow in your mouth takes away body heat and may cause internal cold injuries. If on or near pack ice in the sea, you can use old sea ice to melt for water. In time, sea ice loses its salinity. You can identify this ice by its rounded corners and bluish colour. You can use body heat to melt snow. Place the snow in a water bag and place the bag between your layers of clothing. This is a slow process, but you can use it on the move or when you have no fire. When ice is available, melt it, rather than snow. One cup of ice yields more water than one cup of snow. Ice also takes less time to melt. You can melt ice or snow in a water bag, MRE ration bag, tin can, or improvised container by placing the container near a fire. Begin with a small amount of ice or snow in the container and, as it turns to water, add more ice or snow. Another way to melt ice or snow is by putting it in a bag made from porous material and suspending the bag near the fire. Place a container under the bag to catch the water. During cold weather, avoid drinking a lot of liquid before going to bed. Crawling out of a warm sleeping bag at night to relieve yourself means less rest and more exposure to the cold. Once you have water, keep it next to you to prevent refreezing. Also, do not fill your canteen completely. Allowing the water to slosh around will help keep it from freezing.|
|There are several sources of food
in the arctic and subarctic regions. The type of food fish, animal,
fowl, or plant and the ease in obtaining it depend on the time of the
year and your location. During the summer months, you can easily get
fish and other water life from coastal waters, streams, rivers, and
lakes. The North Atlantic and North Pacific coastal waters are rich in
seafood. You can easily find crawfish, snails, clams, oysters, and king
crab. In areas where there is a great difference between the high and
low tide water levels, you can easily find shellfish at low tide. Dig in
the sand on the tidal flats. Look in tidal pools and on offshore reefs.
In areas where there is a small difference between the high- and
low-tide water levels, storm waves often wash shellfish onto the
beaches. The eggs of the spiny sea urchin that lives in
the waters around the Aleutian Islands and southern Alaska are excellent
food. Look for the sea urchins in tidal pools. Break the shell by
placing it between two stones. The eggs are bright yellow in colour. Most
northern fish and fish eggs are edible. Exceptions are the meat of the
arctic shark and the eggs of the sculpins. The bivalves, such as clams
and mussels, are usually more palatable than spiral-shelled seafood,
such as snails.
The black mussel, a common mollusc of the far north, may be poisonous in any season. Toxins sometimes found in the mussel's tissue are as dangerous as strychnine. The sea cucumber is another edible sea animal. Inside its body are five long white muscles that taste much like clam meat. In early summer, smelt spawn in the beach surf. Sometimes you can scoop them up with your hands. You can often find herring eggs on the seaweed in midsummer. Kelp, the long ribbon like seaweed, and other smaller seaweed that grow among offshore rocks are also edible. Plants include; Arctic raspberry and blueberry, Arctic willow, Bearberry, Cranberry, Crowberry, Dandelion, Eskimo potato, Fireweed, Iceland moss, Marsh marigold, Reindeer moss, Rock tripe and Spatterdock.
