Abstract:

Modeled Lagrangian data using a 1km horizontal resolution Regional Ocean Modeling System (ROMS) run. The Lagrangian model adopted is LTRANS v2b. Particles with sinking speeds of 20 m d-1, 30 m d-1, 50 m d-1 and 100 m d-1 are released at two sediment traps, GC600 (27.375 N, -90.511667 W) and AT357 (27.525 N, -89.71 W) in April and October 2012. Backward simulation of particles is applied to investigate the influence of mesoscale and submesoscale circulations on the trajectories of sinking particles in the Gulf of Mexico.

Purpose:

Lagrangian runs are simulated to investigate how sinking particles transport in the presence of large, energetic Loop Current eddy and where those particles come from. Particulate organic carbon fluxes are calculated from sediment traps deployed at about 100 m above the seafloor at two locations throughout 2012.
