On Sea
Ice with a Kayak and Walking Gail Ferris |
Here in Sea Ice
is not as brittle as freshwater ice it can be like jello depending on where
it forms and how saline the source water is. I found
that by trying to go forward with this method the chunks of ice I dislodged
would just build up under the bow making progress impossible. |

Below is
a photo showing frazzle ice just forming on the surface flowing on the
outgoing tide in Northeast Greenland King Oscar Fjord at the very end of
August. |

This
photo is from Kullorsuaq showing a thin skim of frazzle ice just starting to
form. Ice came late in 1995 because
there were numerous windy days that would remix the water so extensively that
the ice could not coalesce. |

Sea ice
varies greatly in solidity upon the upwelling currents. The ice
pans you see in this picture area small and enough of a mix with fresh water
that their edges are sharp even though they are the typical murky gray color. It is
hard to tell by looking when above sea ice whether it is solid or
gelatinous. Walking on sea ice is the
only way to find out if the ice is solid. Below is
a 1996photo of dogsleds going out in Kullorsuaq, Even
though the snow covered surface may look solid, the ice off peninsulas can be
dangerously mushy. I had
the experience of nearly slipping through as I attempted to walk in the area
to the left off this photo that was near a peninsula. I realized too late that I was in an area
where there were strong currents off that peninsula that were bringing warm
water to the surface that was keeping the ice from forming as a solid sheet
safe to walk on. I was
very lucky on my snowshoes as I saw a dogsled going by and rushed toward the
dogsled trail where the ice was solid. After
that touchy moment I realized why the dogsleds such as the one you see below
went through some areas and avoided other areas. I
watched Lars Jensen drive his dogsled through this area I had my near dunking
and the dogs began to struggle as they worked very hard to keep the sled going through what was deep a
surface nothing more that deep slush.
The sled would have sunk through if they were unable to keep going. Areas
off Kullorsuaq Lars Jensen told me to watch out about and just stick to the
dogsled trails because Walrus can burst through ice and grab unsuspecting
people in an instant. |

In the
picture below is taken from a helicopter of an area behind an island Nussuaq
where there is an open area. This is
evidence of a strong upwelling current.
No matter how cold the air above is the warm upwelling water will keep
the ice from solidifying solidly. |

Flying
via helicopter south toward Tassiusaq I noticed
this view of the ice. |

In the
photo below the ice looks even perfectly smooth with no breaks in it. This is ice to the north of Kullorsuaq in |

I made a
pair of snow shoes in anticipation during the fall when I lived in Kullorsuaq
Greenland and used them to walk on the ice.
There
was one moment when I almost went through the ice. It felt very strange to be walking in what
looked to be a most innocent area not far from land and to begin to feel the
ice shake like jello and start depressing beneath my weight. I
hastened my walking when I could feel that the surface was shaking even more
violently. The
surface looked like the rest of the area a gray opaque nothing especially
different than elsewhere type of surface. The
picture below illustrates the peninsulas in that area. This is
one of those innocent looking areas which looks like
nothing is happening there. I had
paddled my kayak around there a number of times. In a kayak it is just a quiet place with a
few peninsulas jutting out. |
