Abstract:

Analysis of water samples collected during the R/V Endeavor cruise EN559 in the Gulf of Mexico, May 29 - June 20 2015, at cold-seep and control sites. Measurements include the concentration of dissolved nutrients, dissolved organics, cations, anions and dissolved gases acquired from CTD casts. Methane oxidation and bacterial production rate measurements were also performed.

Purpose:

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