CT24B:
Revealing Biogeochemical Processes on Basin Scales through Ocean Transects V Poster

Session ID#: 93298

Session Description:
Biogeochemical processes that affect the cycling of trace elements and their isotopes, as well as carbon, macronutrients and other constituents, are studied using two basic field strategies: sampling at a fixed station or regime to measure rates and examine specific processes, or transects on up to basin scales. Each has its strengths and weaknesses, but transects can gather a broad sweep of information on a relatively short time scale that can then be used to develop a more specific process-oriented approach. Indeed, the GEOSECS program of the 1970’s used the transect approach, and currently the GO-SHIP/Repeat Hydrography and international GEOTRACES programs feature long ocean transects. This session will highlight biogeochemical processes revealed on basin transects that affect trace constituents such as trace elements and isotopes, as well as organic constituents, including carbon and macronutrients. It will also focus on sampling and data analysis methods applied to sampling across basins, and biogeochemical modeling studies that integrate data from long transects into their analyses.
