With the support of the National Science Foundation, we have
completed the first cruise devoted to the GOFS and JGOFS program for the
North Atlantic Bloom studies between March 28 and April 6 on board R/V
Atlantis II. The major task of this cruise, to deploy bottom-tethered mooring
arrays with time-series sediment traps along with current meters at two
critical stations, 34°N and 47°N along 20°W, was accomplished. All 6
sediment traps, 3 on each array, were set at 14-day intervals for 13 periods
from April 3 to September 26, 1989. Their opening and closing times were
synchronized throughout the period of deployment. The arrays and
instruments will be recovered and redeployed in September/October, 1989.
Ancillary water column data, such as CTD, fluorometry, pigments, and major
nutrient distribution, were also successfully completed (except for
transmissometry profiling at the 47°N station) in order to understand the prebloom
setting at JGOFS 34°N, 47°N, and 60°N stations. At the 47°N station on
April 2, the mixed layer depth was 248m.
