Abstract:

Analysis of water and sediment samples collected during the R/V Endeavor cruise EN515 in the Gulf of Mexico, September 7 - 15, 2012, at cold-seep and control sites. Measurements include the concentration of dissolved nutrients, dissolved organics, cations, anions and dissolved gases acquired from 19 CTD casts and 5 sediment cores. This dataset and dataset R1.x132.135:0015 were used in the publication "Ziervogel K, D'souza N, Sweet J, Yan B and Passow U (2014) Natural oil slicks fuel surface water microbial activities in the northern Gulf of Mexico. Frontiers in microbiology 5.".

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.
