from an altitude of 400 meters. Some of the
ice fields are huge (up to 10 miles in diameter,
not shown here) but this is first-year ice
with thickness less than 100 cm. In September
and October, strong storms can destroy these
fields and our buoy could sink. Stronger,
thicker ice is needed. |

Searching for the right ice
On August 20th 2003, at 7:30 AM Louis S. St-Laurent’s
position was 80° 00N, 150°00 W
. This is our farthest North station and the turning
point of our expedition.
During next two weeks, we will gradually move in
the direction of Kugluktuk. There is still a lot
of work waiting for us. The event of reaching the
expedition’s turning point also became a turning
point in the weather and sea ice conditions.
Pleasant, cooperative Arctic weather that had accompanied
our work during the first two weeks, changed rapidly
in the morning. We planned to deploy one of our
four expendable buoys on August 21st, but wanted
to make sure that the buoy would be installed on
an old ice field with a thickness of about 2 meters
so that it would work for at least one year, sending
oceanic water temperature and salinity data to the
Woods Hole Oceanographic Institution two times per
day. Therefore, Scott Payment, the ship’s Ice Observer,
Adrian Godin, helicopter pilot, and WHOI scientist
Andrey Proshutinsky executed a 90-minute ice reconnaissance
helicopter flight to search for an appropriate ice
field.
No good ice fields were found, and fog, clouds and
a general decrease of visibility forced us to return
to the ship. We decided that the search would be
repeated during the 1-2 days, hoping that winds
and currents would move the old and thick ice to
the southeast – region of our future work.
