Ship name (ship code)RRS Discovery (74E3)
Cruise identifierD198
Cruise period1992-11-11 — 1992-12-17
StatusCompleted
Port of departureStanley, Falkland Islands (Malvinas)
Port of returnPunta Arenas, Chile
PurposeResearch
ObjectivesPhysical, chemical and biological study of algal blooms. The overall objective was to evaluate the magnitude and variability of biogeochemical fluxes (particularly carbon and nitrogen), during early summer in the South East Pacific Sector of the Southern Ocean, with emphasis on rates and processes in the marginal ice zone.
