Lagrangian Sediment Trap
MBARI adapted the design of an existing float to function as a drifting sediment trap under an iceberg. The sediment trap was deployed from an icebreaker in the Antarctic during a 2008 engineering test cruise funded by NSF for Ken Smith and Bruce Robison. The purpose of the sediment trap is to capture particulate organic matter exported from the enriched ecosystems newly discovered under icebergs and quantify their contribution to the global carbon cycle. Based on what was learned about operations over the side of an icebreaker from the first expedition, the trap will be modified, tested in Monterey Bay, and redeployed during the second Antarctic cruise in March/April 2009.
