A Wild and Crazy Day
Rumor has it around here that the first and last dredges are "bad luck
dredges". If you have been following along for the past 2 months, you know
that our first dredge was lost and is on the ocean floor. So did the rumor
hold true for our last dredge? It certainly did, and that's only the
beginning.
The last 24 hours have been a roller coaster. Yesterday afternoon, the
weather was gorgeous as we completed our 100th dredge! We celebrated this
centennial dredge with photos and high spirits. Shortly after this
occurred, however, the weather drastically changed. Within a few hours, we
were in winds over 40 mph and the temperature (with the wind chill) was 15
degrees below zero Fahrenheit!
Despite the conditions, the last efforts to collect data from Gakkel Ridge
continued into the night. Dredge #101 was attempted, but we drifted off
course and it came up with no rocks. Then a CDT cast was attempted
(collection of water samples to find evidence of hydrothermal plumes).
Problems arose with this effort, too. When the CTD was in the water, the
wire it was attached to was forced under the ship due to the strong drift.
It was rubbing against the hull, which created a dangerous scenario. The
decision was made to halt the process and bring the CTD to the deck, but the
winch that pulls in the wire quit working, and the CTD stuck in the water
for several hours. When it finally arrived on deck, it was instantly
covered with ice! At least some water was collected and will be usable for
analysis.
When I awoke early this morning and opened my porthole, all I saw was
whiteness. The weather conditions were worsening. The temperature had
dropped to 25 degrees below zero, the winds had increased, and the decks
were covered with snow and ice. I arrived for my shift to find that we
planned one more dredge-- #102. After spending several hours fighting the
conditions, the final dredge was canceled. Soon afterwards the call was
made to secure all decks and no one was permitted outside for the remainder
of the day.
Our time for dredging officially ended at noon today, and we began our
transit to meet with our partner the Polarstern and begin our journey home.
Soon after we began our travel to the rendezvous point, the call came that
they were stuck in the ice and needed rescued! However, the visibility was
so poor and the conditions were so questionable that the decision was made
to drift together and re-evaluate the situation. It is now evening and we
are still drifting. Tune in tomorrow...
If there is one thing I have learned today, it is that the unpredictable
Arctic gets the last say.
The weather prevented the last dredge attempt.
Hedy Edmonds stands in front of the CTD. The ice melted off and all was well.
Yesterday was a beautiful day as we moved onward from dredge #100 (with our shadow preceding us).
An empty dredge sits on the ice covered deck. This was dredge #102.
We happily celebrated our 100th dredge yesterday. Little did we know then that bad weather would make #100 our last successful dredge.
