Snow has temperature???? Perhaps, you just believed
snow was cold. However, snow acts as a warm blanket.
It insulates whatever lies beneath the snow pack from
the cold air above. Therefore, the snow closest to
the ground will be the warmest layer. The snow on top
will be the coldest layer. The temperature of the snow
can be measured by using a thermister that is
connected to a digital readout. The thermister is
placed in the snow and the reading is read on
the screen.
The following temperature numbers were taken while
doing a snow pit several days ago. Make a line graph,
plotting temperature versus height.
Height (cm) Temp (degrees Celsius)
43 -10.4
37 -11.1
33 -9.6
29 -10.8
25 -10.5
20 -9.1
16 -9.0
12 -9.2
7 -7.0
0.0 -6.4
The temperature of the air on this parcticular day was
–8.1
degrees Celsius.
WHERE IS MRS. CHEUVRONT??? LET'S PLOT!!!
LATITUDE: 69.03833 degrees North
Longitude: 155.61664 degrees West
The difference between "cold" and "extreme cold" is
zero degrees Fahrenheit and –30 degrees Fahrenheit.
The difference between cold and extreme cold is being
able to have exposed hands for minutes compared to
seconds before there is pain biting at the skin. The
difference between cold and extreme cold is warm bunny
boots and icy/frozen bunny boots. The difference
between cold and extreme cold is cold nostrils and
frozen nose hair. The difference between cold and
extreme cold is hair and frost-covered hair.
Life is tougher when it's colder. We have traveled
far north above the Arctic Circle. The cold
encircles,
envelopes our every action. The same tasks must be
accomplished despite the numb-biting, extreme cold.
Snow must be melted for water, tents must be erected,
therma-rests must be blown up, food must be cooked,
power-bars must be thawed, and science measurements
must be taken. In the cold, more layers of clothes
must be worn. It is essential to have faces covered
to keep our skin from getting frostbite. It is a
continuous, never-ending task to warm boots to keep
your feet and toes from freezing.
More food is consumed. Food is no longer looked upon
as tasteful, but is now looked upon as energy. It is
the fuel for the inner body furnace. The tedious,
multitude science measurements are still accurately
collected and recorded. The team still works as one.
The team works harder together and more uniformly in
the cold.
The day was a long measurement day. A complete site
was recorded along with two abbreviated sites. At 6
pm, the cold, long process of Class I chemical
sampling began. The cold made the rubber gloves
metamphorize into ice-hard objects. Four hours later
the samples had been collected, and our bodies were
completely chilled.
Camp is set up and hidden in a creek surrounded by
immense snowdrifts. These will provide protection
against the wind. The body longs for rest in the warm
sleeping bags.
Temperature Max: -23 degrees Celsius
Temperature Min: -34 degrees Celsius (about –30 F)
