Objectives and Narrative |
This is one of two cruises aimed at evaluating the controls over mesopelagic remineralisation depth. This is the depth to which material sinks when it leaves the surface ocean, a factor we know to be a critical control over climate. There are three serious hypotheses explaining what controls this depth; plankton community structure, temperature and oxygen concentrations. COMICS will test two of these; oxygen and community structure with this cruise exaimining the role of community structure; more precisely how the evolution of community structure over the course of the bloom affects sinking depth.
In order to evaluate this three long stations of about a week duration each were worked over a 1 mo period between mid Nov and mid Dec in the major plankton bloom which occurs NW of South Georgia. At each station surface community structure and a variety of metrics of downward particle flux were measured, together with estimates of the biomass and growth rates of the major taxonomic classes of organisms responsible for consuming sinking material. All operations were conducted in the vicinity of BAS station P3 (52 40 S, 40 06 W). |
