Autonomous Measurements of Carbon Flux During the 2008 North Atlantic Spring Bloom



Wednesday - January 7, 2009

Pacific Forum – 3:00 p.m.

Using optically-instrumented Lagrangian mixed-layer floats and Seagliders, the 2008 North Atlantic Spring Bloom experiment provided continuous observations of the bloom –– from pre-bloom to post-bloom conditions –– in a region southeast of Iceland near the historical Joint Global Ocean Flux Study (JGOFS) and MLML sites. The goal of this collaborative experiment was to understand carbon export by combining a new generation of autonomous sampling platforms with traditional and modern shipboard observational methods. The experiment succeeded in capturing a major carbon flux event, dominated by diatoms cells and cysts, and hence demonstrated a new way to sample carbon flux events. Our observations show the power of coordinated autonomous and ship-based sampling, using complementary bio-optical and biogeochemical measurements to measure coupled biophysical processes controlling ocean carbon fluxes. Principal collaborators are Eric D’Asaro and Craig Lee, University of Washington.
