The USCGC Healy Bow Wash System
(Deluge System) in the Canadian Arctic ice floe:
The Bow Wash System is employed when there
is an abundance of snow. Heavy snow renders
the ship less capable and consequently slows it down.
Water spouts from each side of the bow to wash
the snow off the ice and to provide a liquid
lubricant to the sides of the ship. This system
reduces the friction of the snow
against the ship and lessens its resistance.
It facilitates the ship's forward movement
over the ice. (Refer to my journal
entries of May 6, 2000, "Profiling Ice Thickness" and
May 10, 2000, "Testing Snow Density.")

Douglas Griggs drilling, Dr. Stephen Jones
documenting, US Navy personnel in the background
on the Canadian Arctic multi-year ice floe.
They are drilling a core for collecting
and recording ice temperatures.

An ice core from the Canadian Arctic multi-year ice floe.
The ice core is drilled every 10 cm
for the placement of the probe that is used to collect
and record ice core temperatures.

multi-year floe demonstrating partial
ice thickness and standing just in front
of the channel broken by the ship into the floe.
Note the brash ice in the channel path.

Sandra Kolb (TEA) on the Canadian Arctic ice floe
demonstrating the completed size of a snow house
large enough tosleep one or two people.
Note the beautiful bluish light created
from the sunlight filtering through the snow into the interior.

Nilas Ice in the Canadian Arctic.
Nilas Ice is the second stage of ice development.
The first stage is New Ice and the third stage is Young Ice.
