Over the last few years, our lab has been involved in a large number of oceanographic field experiments all over the world.

• Since 1988, we have been mearsuring DIC (dissolved organic carbon) and alkalinity in the Sargasso Sea as part of the U.S. JGOFS BATS time series. Until March 2006, measurements took place aboard the RV Weatherbird II (below left). In March of that year, the RV WBII was replaced with the larger RV Atlantic Explorer (below right).

• Our lab is part of the ongoing CLIMODE project studying the dynamics of 'Eighteen Degree Water' (EDW), the subtropical mode water of the North Atlantic. In February 2006, our technician was aboard the RV Atlantis (below left) taking DIC and Alkalinity measurements in the North Atlantic. We are also part of upcoming cruises in February/March 2007 aboard the RV Knorr (below right).

• In summer 2004 and 2005, we took part in 2 of 4 cruises in the Sargasso Sea to track meso-scale eddies and measure their phsyical an biogeochemical properties aboard the RV Weatherbird II and the RV Oceanus (below left). See more information on the EDDIES project here.

• In 2002 (Spring and summer) and 2004 (Spring, summer and fall), technicians from our lab were aboard the USCGC Healy (above right) as part of the SBI II project. The cruises took place in the Chukchi and Beaufort Seas. Read about Christine Pequignet's experiences aboard the USCGC Healy in the Arctic Ocean here.

• In May 2001 aboard the RV Oceanus (above left), we were part of a team answering the question: "Elevated N* in the western Sargasso Sea: Local or non-local source?"

• Also in 2001, we were on board the RRS Darwin in the Indian Ocean studying hydrothermal plume processes.
