Abstract:

Analysis of water and sediment samples collected during the R/V Endeavor cruise EN505 in the Gulf of Mexico, April 12 - 24, 2012, at cold-seep and control sites in VK826, MC252, GC600, OC26 and VK906. Measurements include the concentration of dissolved nutrients, dissolved organics, cations, anions and dissolved gases aquired from 8 CTD casts and 6 multiple corer drops are included.

Purpose:

The purpose of this dataset it to assess 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.
