PurposeResearch
ObjectivesThe goal of the GEOTRACES project is to re-visit in 2010-2011 the West Atlantic GEOSECS-1972 cruise to produce complete ocean sections of (A) novel trace elements and several isotopes, (B) transient tracers of global change, (C) microbial biodiversity and metabolism, and (D) interpretation by ocean modelling where the ocean observations A-C serve for verification of the models. Many of these 'tracers in the sea' are the first-ever ocean sections (sub-projects A, (B), C), while others (sub-project B) will allow unravelling of transient global changes over the past ~35 years by comparison with data of 1972-1973 GEOSECS and later cruises (notably 1981-1983 TTO, WOCE 1990's; CLIVAR).
