Laser In-Situ Scattering and Transmissometer (LISST) and Conductivity Temperature Depth (CTD) measurements and supporting data collected in response to the Deepwater Horizon oil spill Incident from multiple vessels in the Gulf of Mexico from 21/04/2010 to 24/08/2010 (NCEI Accession 0086284)

At the request of the United States (U.S.) government and BP, research scientists and technicians from the Centre for Offshore Oil Gas and Energy Research (COOGER), Fisheries and Oceans Canada (DFO) conducted at-sea monitoring operations with other scientific experts on board vessels R/V Brooks McCall and R/V Ocean Veritas to assist in a comprehensive environmental monitoring program in response to the Deepwater Horizon oil spill.

Throughout the period from May 8 to August 24th the DFO COOGER team maintained a continuous monitoring program that recovered a total of 3197 unique water samples from 404 stations at depths down to 2000m for analysis of dispersant effectiveness by characterizing oil droplet size and UV-fluorescence. This collection of data is organized into nine database tables which include all data used by COOGER to conduct analyses.
