Our work has gone relatively smoothly over the last four days. We completed
four more profiling transects with all systems working. The computer tech on
board finally fixed the system here so that we could ftp files to the COAST web
page. I sent over the first three Chameleon profiles that Sasha prepared and
also the summaries for temp, sal, denisty, turbulence and turbity for six of the
profiling trasects. If you are limited on time for downloading figures the best
ones are the summaries with file names including 1_7. These are the 6 profile
summaries (profile #2 was aborted when the Chameleon went under the ship). Crab
pots have reappeared and moved some so we continue to restrict the profiling to
daylight hours when we cross the 100-50 m isobaths.
Jim Moum promised a short description of the Chameleon results later today and I
will post it when I get it.
Yesterday, (Tuesday) as part of the profiling transect we filled carboys with
water from the bottom boundary layer and from the surface water every half hour
for discrete chemical measurements of the bottom and surface features. It was a
real marathon for all the water filterers on board with non-stop filtering from
10:00 until 17:00. Last night at our mid-shelf station (CH-5) Burke's pump
system and winch lost power and blew a 30 amp fuse. The sled will be out of the
water until the source of the problem is known and repairs can be made.
We had planned a 48 h time series to examine tidal cycles and the day/night
transitions for phytoplankton photic responses for today and tomorrow (Wednesday
and Thursday). We have postponed this until we have some feedback from Burke
about the status of his pump. Meanwhile Moum's group is back in the water with
their profiler and we should get a good transect in during the 25-30 kt winds
that blew up this morning.
