Abstract:

Analysis of water and sediment samples collected during the R/V Falkor cruise FK006b in the Gulf of Mexico, November 4 - 28, 2012, at cold-seep and control sites. Measurements include the concentration of dissolved nutrients, dissolved organics, cations, anions and dissolved gases acquired from niskin bottles deployed on 16 ROV dives and 11 sediment cores.

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.
