Abstract:

Dissolved trace element data collected on four cruises in the vicinity of the Deepwater Horizon blowout. Cruises were in early May 2010, late May 2010, October 2010, and October 2011. Besides data on dissolved concentrations of metals (including Fe, Mn, Ba, Co, and Cu), dataset also includes dissolved oxygen, nutrients, and total PAH's. There is additional data on trace element concentrations in oil and dispersant as well as experiments in which natural waters were mixed with oil and/or dispersant.
