Title: NOAA RESTORE Science Program: linking habitat to recruitment: evaluating the importance of pelagic sargassum to fisheries management in the Gulf of Mexico: microplastic concentration and ingestion in the Northern Gulf of Mexico, 2017-07-20 to 2019-06-04 (NCEI Accession 0232040)
Abstract: This dataset includes microplastic concentration and ingestion information from samples of sargassum and open water habitats collected in the northern Gulf of Mexico during four cruises across three years (2017-2019). Microplastic concentration data includes samples from both Sargassum and open water habitats collected in May and July of 2018. Microplastic ingestion data includes sargassum-associated juvenile fish samples from sargassum habitats collected in July 2017, May 2018, July 2018, and May 2019.

Supplementary information: Methods:
Microplastics and Sargassum-associated fishes were collected during four sampling cruises between 2017 and 2019. Microplastics were collected using net tows at the surface through Sargassum and open water habitats. Sargassum associated juvenile fishes were collected using net tows, Sabiki hook and line fishing, and opportunistic dip netting within the Sargassum habitat. Microplastics from May 2018 and July 2018 were sorted out of samples under dissecting microscopes, treated with potassium hydroxide (KOH) in order to remove any other organic material, filtered onto Whatman glass fiber filters (grade GF/F-0.7 µm), dried, and weighed to the nearest mg for both Sargassum and open water samples. Sargassum-associated juvenile fishes from July 2017 and July 2018 were dissected, guts removed, weighed, and opened under dissecting microscopes in order to record diet items and microplastic ingestion (select species were also analyzed for May 2018 and May 2019). Clean techniques were used during sorting and gut analysis, which included wearing 100 % cotton lab coats, cleaning the work space before use, using non-plastic tools where possible, and placing out water blanks for every sample in order to capture microplastic air contaminants.
