RRS John Biscoe (74JB)

Cruise identifier

JB04

Cruise period

1983-07-27 — 1983-10-10

Status

Completed

Port of departure

Grytviken, South Georgia and the South Sandwich Islands

Port of return

Montevideo, Uruguay

Objectives

The primary objective was to investigate krill physiology and behaviour at a time when concentrations of the primary food source (phytoplankton) were low. However, low krill populations were encountered and an alternative study of ichthyoplankton was used to occupy the remaining cruise time.
