PurposeResearch
Objectives1. To recover moorings deployed 59N 22W in 1989.
2. To participate in the BOFS Langrangian experiment by:
(a) Coordinating JGOFS level 1 observations every two days between the two Darwin cruises.
(b) Investigating quantitatively and qualitatively the particulate material throughout the water column, sampling it using stand-alone pumps, sediment traps, large volume water bottles and coherent light photography.
(c) Sampling the pelagic communities in the top 1000m of the water column to assess their contribution to the biological pump.
(d) Collecting core samples of the surficial sediment to evaluate the microbial response to increases in organic input associated with the onset of the spring bloom.
(e) To maintain contact with, and service the drifting moorings deployed for the experiment.
