Subject: Revelle Report 1-6 Feb.
During the last five days we completed three more profiling transects
between
CH-1 and CH-6.5. These included chemistry and optics for the surface
water and
filling carboys with surface water for the organic and pigments
measurements.
This will be a very nice series for comparisons across the sharp
salinity
gradients along the CH-line on 1 and 2 Feb compared with a narrower
range in
surface salinity conditions on 5 Feb.
We took advantage of the good weather on 5 Feb to retrieve Moum's
bottom lander.
The spar buoy was detached so we needed to drag for the bottom line to
pull the
weight and lander back on board. The chief fabricated a grapnel and
when that
failed, gamely contrively a fix to it. During the actual recvovery
(which took
three drags and 12 + hours) the ship's crew were open-minded and
resourceful and
contributed to the success. The spar buoy was later found near Cape
Lookout.
During the work near CH-5 we were able to include five light/dark
transitions
for Ricardo's fluoresence measurements.
On 4 Feb Moum's group took a break and we continued with ADCP and
underway
surface sampling and bottom mapping during the night. Our last
profile
(Chameleon #13) was completed on 5 Feb and we are finishing off with
more bottom
mapping and several more ADCP transects acroos the CH-line.
In summary, we are delighted with the results of the winter cruise and
are
returning to Newport this afternoon after completing 12 successful
profiling
transects, 18 pump stations, and more than 50 ADCP transects along the
CH line.
Thanks and congratulations to all the scientists and crew aboard
Revelle! Good
luck to the WECOMA for their last few days of work.
