Abstract:

Analysis of water and sediment samples collected during the R/V Endeavor cruise EN509 in the Gulf of Mexico, May 26 - June 19, 2012, at cold-seep and control sites. Measurements include the concentration of dissolved nutrients, dissolved organics, cations, anions and dissolved gases aquired from 35 CTD casts and 17 multiple corer drops are included.

Purpose:

The purpose of this dataset it to asses the impacts of the Deepwater Horizon blowout on sediment and water chemistry on fallout sites and compare these impacts to naturally occurring oil and gas seeps.
