Hercules Spill Response Cruises, Water Chemistry. Louisiana South Timbalier Block 220, 27-30 July (R/V Acadiana) and 25 August (R/V Weatherbird) 2013

Hydrographic and water column data were collected during a cruise to the Hercules 265 site using a CTD-rosette system aboard the R/V Acadiana. We characterized the physical and chemical properties in the water column at/near the rig in the immediate aftermath of its blowout. The ship departed Cocodrie LA on 07/27/2013 for a day cruise, then returned to the rig on 07/29/2013 - 07/30/2013. A second visit on 25 August by the R/V Weatherbird provided additional hydrographic and chemical data from the water column.
