Abstract
Benthic meiofauna samples from the northern Gulf of Mexico were collected with multi-corers on research cruises during 16 September - 30 October 2010, 23 May - 11 June 2011, and 29 May - 28 June 2014. Organisms were identified taxonomically and their abundance was determined. Taxonomic richness, diversity, and evenness of meiofauna, as well as nematode to copepod ratios were calculated at 34 stations for each of the three sampling times.
Purpose
The analysis of benthic meiofauna in samples from 2010, 2011, and 2014 was conducted to determine how the Deepwater Horizon oil spill affected these communities over time.
