Description:Using gap-free satellite observations of chlorophyll-a (Chl-a) concentration, sea surface temperature (SST), and sea surface salinity (SSS) following Hurricane Ian in 2022, we demonstrate the capabilities and benefits of the collective satellite remote sensing approach to monitor the ocean physical, biological, and biogeochemical responses to a hurricane. The evolvements of Chl-a, SST, and SSS from 26 September to 7 October show that ocean responses to the hurricane are regional-specific and the spatial maps of changes in these three ocean properties are distinct. Quick SST and SSS changes were observed following the passage of Hurricane Ian, while Chl-a change lagged hurricane winds for about 3–4 days. The ocean features of the elevated Chl-a, reduced SST, and enhanced SSS after Hurricane Ian were found to last until late October 2022. Results in the temporal variations show that Chl-a more than doubled, SST dropped by > ~2°C, and SSS increased by > ~1 psu in the continental shelf of the Gulf of Mexico.
