Cruise Info. 
Ship name (ship code)Professor Shtokman (RUPS)
Cruise identifierOMEX-0898
Cruise period1998-08-01 — 1998-08-11
StatusCompleted
Port of departureA Coruña, Spain
Port of returnA Coruña, Spain
PurposeResearch
ObjectivesThe main objective of the cruise is the study of physical, chemical and biological properties in the continental shelf and shelf-break zone of the Galician coast near the Rias Baixas (NW Spain) during summer. The results obtained will be used as input data to models and biogeochemical budgets to determine the exchange of matter between the continental shelf and the ocean. This cruise is part of Workpackage 2 of the project OMEX-II, Phase II. The study area is located between Cape Finisterre (43 00' N) and Ria de Vigo (42 09' N).
