Abstract:
Analysis of water and sediment samples collected during the R/V Endeavor cruise EN528 in the Gulf of Mexico, July 7 - 22, 2013, at cold-seep and control sites. Measurements include the concentration of dissolved nutrients, dissolved organics, cations, anions and dissolved gases acquired from 40 CTD casts and 11 sediment cores.
