Abstract:

The cruise investigated how complex fine-scale structure and processes in coastal waters dominated by pulsed-river plumes control the exposure, impacts, and ecosystem recovery from offshore spills like the Deepwater Horizon release of 2010. Data were collected along three transects in the northern Gulf of Mexico in water depths from 10 meters to 60 meters using the Reson 7125 multibeam sonar and an In Situ Ichthyoplankton Imaging System (ISIIS). Stations along the corridor completed CTD casts, trace metal testing, water chemistry, FlowCam analysis, radio-isotopes testing, and productivity experiments. This dataset, remotely hosted at NCEI, contains the s7k (water column) data obtained during the R/V Point Sur cruise, PTS02.

Purpose:

CONCORDE is the CONsortium for oil spill exposure pathways in COastal River-Dominated Ecosystems (CONCORDE). It is one of 12 research consortia funded by the Gulf of Mexico Research Initiative (GoMRI) to conduct scientific studies of the impacts of oil, dispersed oil, and dispersant on the Gulf’s ecosystem and public health during 2015-17.

Data Parameters and Units:

Relative acoustic backscatter relating to impedance contrasts within the water column across a swath of 512 beams.

Instruments:

Reson SeaBat 7125 high-resolution multibeam echosounder
