Purpose | Turbidity can have a significant impact on coral reef ecosystems, through light limitation, sedimentation, and eutrophication (e.g., Bessell-Browne et al. 2017). Several U.S. reef jurisdictions have made as a priority (e.g., FDEP 2004 Local Action Strategy), to determine the tracks and fates of turbidity in their waters. National Oceanic and Atmospheric Administration’s Coral Reef Conservation Program (NOAA - CRCP) funded a collaborative project in 2013-2015 (Project #881), to help meet this priority. Potential sources of turbidity described in the literature include natural sediment resuspension due to wind and waves (e.g., Storlazzi and Jaffe 2008), tidal runoff and coastal inlets and oceanic wastewater outfalls (Staley et al. 2017), and other human activities such as dredging (e.g., Wang and Beck 2017). Because of the complexity both of potential sources and of coastal circulation and mixing patterns, in situ monitoring of turbidity and associated sedimentation is challenging (e.g., Whinney et al. 2017). Using satellite remote sensing to monitor coastal turbidity has a variety of potential advantages (e.g., Hu et al. 2012). NOAA CRCP Project #881 was funded to provide managers with historical maps of turbidity, and alerts and maps for near real-time tracking of turbidity plumes, in coastal waters of three CRCP priority jurisdictions: American Samoa (including Faga'alu), CNMI (including Saipan, Rota/Talakhaya, and Tinian), and south Florida (including reefs offshore of projects for port/tunnel expansion and beach refurbishment in three Counties). Academic partners (USF) in collaboration with AOML began back-processing and analyzing remote-sensing data in 2013 to produce maps of "relative turbidity", an indicator of change in available light, for the three target regions. These relative turbidity or "Color Index" (CI) maps are gathered via MODIS ocean color instruments on two polar-orbiting satellites at 250 m spatial resolution. Maps have been produced for analysis from July 2002 to the present, and new maps are made available to management partners in all three jurisdictions in near real-time via public Web site. |
