Pelagic cruise CTD casts and ship-track velocity and weather data near the Mississippi Delta, July 2014

During July, 2014 (2014-07-07 - 2014-07-10), several members of CARTHE and other PIs conducted a water column sampling expedition aboard the R/V Pelican (PE15-01, cruise DOI https://doi.org/10.7284/904713). The objectives of the expedition were to sample the Mississippi River plume at the surface and the remnants of the Deepwater Horizon plume at depth, using guidance from shore-based scientists monitoring ocean color, temperature, and salinity. Execution of the expedition followed closely the rationale of the GLAD expedition carried out by CARTHE in its use of shore-based scientific guidance; however, the features monitored during the expedition were different (freshwater buoyant plume and salinity fronts). Samples were taken from five primary sites and several secondary sites to complete a hydrographic section relative to the Mississippi River plume.
