RRS Frederick Russell FR4/85
Cruise summary report
|Ship name (ship code)||RRS Frederick Russell (74GG)|
|Cruise period||1985-06-26 — 1985-07-07|
|Port of departure||Plymouth, United Kingdom|
|Port of return||Plymouth, United Kingdom|
|Objectives||1. To investigate benthic invertebrate community structure (macrobenthos and meiobenthos) at Shelf, Slope and abyssal stations as it relates to production and sedimentation processes in the water column. To collect and process a series of replicate benthic samples from three stations, completing the depth range of sampling started on FR 7/84.
2. To determine the community structure of pelagic organisms (particularly species body size distributions and species abundance patterns) at one station (CS2), for comparison with the benthos.
3. To measure in situ and on deck primary production at all three stations and to partition production into different size-classes of phytoplankton: to measure the abundance and vertical distribution of phytoplankton, bacteria and flagellates: to measure bacterial production throughout the water column.
4. To relate light penetration with particulate load at all three stations.
