Using Landsat and AVIRIS satellite imagery and 2010-2011 NRDA\u00a0observations, the authors estimated Sargassum coverage in oiled areas ranged from 1296 \u00b1 453 km2 (for areas with > 5% thick oil) to 736 \u00b1 257 km2 (for areas with > 10% thick oil).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"float: right;\" src=\"https:\/\/www.marine.usf.edu\/c-image\/wp-content\/uploads\/2019\/09\/Sargasum-romero.jpg\" alt=\"Sargassum\" width=\"242\" height=\"182\" \/>The most significant result from this study is the finding that all satellite instruments and high-altitude airborne instruments will miss significant amounts of <em>Sargassum<\/em> in all seasons. Therefore, even though they could provide general distributions of large <em>Sargassum<\/em> patches, satellite data alone are insufficient to provide accurate estimates of the total <em>Sargassum<\/em> coverage. Scaling factors using the much higher-resolution observations from low-altitude airborne measurements are required to provide a more accurate estimate of <em>Sargassum<\/em> coverage. At present, the Landsat-based <em>Sargassum<\/em> coverage estimates scaled using low-altitude airborne measurements represent our best knowledge of <em>Sargassum<\/em> coverage before, during, and after the DWH oil spill in 2010.<\/p>\n<p>Full Citation:\u00a0Hu, C.; Hardy, R.; Ruder, E.; Geggel, A.; Feng, L.; Powers, S.; Hernandez, F.; Graettinger, G.; Bodnar, J.; McDonald, T.
