Photos of sediment trap, sediment sampling, and sediment analysis

Samples are recovered from the sediment trap once every 9-12 months. Cruises to recover and redeploy the mooring take place on the UNOLS vessel, R/V Pelican, operated by LUMCON, in Cocodrie, Louisianna. On these cruises water is collected for isotopic and trace metal analysis, as well as to measure parameters of the carbonate system (dissolved inorganic carbon, total alkalinity, pH). Sometimes live foraminifera are collected with a plankton net for additional geochemical and genetic analyses.
