Abstract

Using high-resolution airborne measurements and more synoptic coverage of <a title="Learn more about Landsat from ScienceDirect's AI-generated Topic Pages"> Landsat </a> measurements, we estimated the total <a title="Learn more about Sargassum from ScienceDirect's AI-generated Topic Pages"> Sargassum </a> coverage in the northeastern <a title="Learn more about Gulf of Mexico from ScienceDirect's AI-generated Topic Pages"> Gulf of Mexico </a> (NE GOM) during 2010, with the ultimate purpose to infer how much Sargassum might have been in contact with oil from the Deepwater Horizon oil spill. Mean Sargassum coverage during the four quarters of 2010 for the study region was estimated to range from ~ 3148 ± 2355 km 2 during January–March to ~ 7584 ± 2532 km 2 during July–September (95% confidence intervals) while estimated Sargassum coverage within the integrated oil footprint ranged from 1296 ± 453 km 2 (for areas with > 5% thick oil) to 736 ± 257 km 2 (for areas with > 10% thick oil). Similar to previous studies on estimating Sargassum coverage, a direct validation of such estimates is impossible given the heterogeneity and scarcity of Sargassum occurrence. Nonetheless, these estimates provide preliminary information to understand relative Sargassum abundance in the NE GOM.
