Day 14
6/13/98
What a day! To say things went like a whirlwind from sunup to sundown
would not be correct in at least a couple of ways but if the sun had
gone down the day would have still been twice that busy. We got
underway at about 3:00 AM and made pretty good time for most the
morning. The ice is still well over a meter thick but there are more
polynyas which indicate a decrease in pressure and gives the displaced
ice a place to go as the ship crashes through the floes.
A polar bear sow and yearling cub were spotted off the bow this morning
and they paralleled the ships course for about two miles. They remained
about 200 yards off and offered plenty of good viewing to most of the
crew that turned out for their first good bear sighting. The ship had
apparently bothered them during a meal because their muzzles were
bloody and several people said they saw the cub with something in it's
mouth for several hundred yards. They were an awesome sight as they
climbed over the ridges and seemed to effortlessly move across the ice
with that pigeon toed gait common to these great beasts of the arctic.
Chlorophyll's to run, lab gear to clean up, journals to catch up on,
and general busy work kept both Aaron and I occupied for most the
morning. Just as lunch was finishing up we parked the ship and station
#7 got rolling with little wasted motion. We came to rest with a 1st
year ice floe holding us fast on the starboard side and a small floe of
very dirty ice surrounded by clean white snow just off the port side.
The flourometer was in the water before the ice crew had cleared the
side of the ship as the crane got us onto the dirty floe. The ROV went
down for a look at the bottom as soon as the fluorometer was back
aboard and found enough activity that a box core was put on the
schedule for an end of station activity. We began punching cores from
both dirty and clean ice, as the helicopter took off for an ice
reconnaissance flight. The CTD rosette went down to collect water
samples and as soon as it surfaced the divers and ROV made ready for a
plunge.
We were once again attempting to set up an above and below the ice
measurement and communication system. This was an especially
challenging activity at this station due to the fact that the dirty ice
floe we were working on was well over 2 meters thick with a very rough
and irregular bottom surface. This required the ROV to do a lot more
looking up rather than forward and the divers were able to assist by
making sure the ROV was on the right course as it tried to get from the
dirty floe to the clean one. We tried to lower small strobe lights
through the core holes but they came to rest on little ledges beneath
the ice which did not allow them to get all the way below the floe.
As it turned out this dirty floe had an abundance of shells and egg
sacs lying on the surface and we even found a dead isopod (a little
horseshoe crab looking critter) in one of the melt ponds. Pete and
Aaron scoured the surface for as many animal parts as they could find
while we continued to bob the strobes and push our stakes down the
holes. We were out on the ice for over five hours and though it wasn't
terribly cold, the wind did a very good job of sucking the heat right
out of me and I had a good chill going by the time we got back aboard.
The dry lab was the center of activity as samples were being organized,
logs brought up to date, and mustangs and boots being traded out for
warm, on board attire. The MST's readied the box core for a drop as the
benthic group suited up for a chilly evening of work. There appeared to
be some problems with the brake on the winch that lowers the box so
repairs looked to be tops on the list.
Overall it had been a very productive day for the science group aboard
Polar Sea. As I observed all the activities taking place both on and
off the ship it once again made me feel very lucky to be part of the
entire evolution. Women and men, civilian and military, young and old,
experienced and rookies, all working together to further our
understanding of the arctic. Way cool!!
