Given technician experiences with preliminary sensor deployments and results from previous studies, one objective of this project was to identify possible sensor interferences and develop standardized empirical correction procedures. Another objective of this project was to test how well extracted CHL-A (micrograms/L) could be predicted from the suite of YSI EXO sensors. While there is value in the YSI EXO Total Algae (TAL) sensor's relative fluorescence units (RFU) for short-term or single-site chlorophyll measurements, reliable predictions of extracted CHL-A (micrograms/L) would provide a standard measure to compare among sites and with historic data. Concentrations of the photosynthetic pigment chlorophyll a are used as a proxy for phytoplankton biomass by estuarine scientists and managers to study eutrophication, food web dynamics, and harmful algal blooms. Traditionally, chlorophyll has been measured by filtering a water sample and extracting pigments from the filter in a laboratory, which is the current practice employed by the NERRS in monthly grab samples; however, monthly measurements are not sufficient for tracking plankton dynamics, which fluctuate hourly. Recent sensor technology development allows high-frequency, in situ measurement of chlorophyll on the same YSI EXO sondes used in the NERRS System-Wide Monitoring Program (SWMP). While in situ measurements are related to extracted measurements, there are variations in the environment that cause inconsistencies. Before this project, no tested relationships existed for the EXO sensors, and SWMP practitioners were asking for this information so they can respond to local and national needs for algal bloom research. completed Office for Coastal Management 2234 South Hobson Avenue Charleston SC 29405-2413 https://www.coast.noaa.gov/ WWW:LINK-1.0-http--link Office for Coastal Management Website Website listed for Office for Coastal Management information custodian asNeeded EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > ESTUARY theme Global Change Master Directory (GCMD) Science Keywords 23.3 chlorophyll estuary HARMFUL ALGAL BLOOM (HABs) estuary monitoring estuary nutrients estuary water quality fdom fluorescence high frequency interference temperature turbidity theme Elkhorn Slough NERR, CA Grand Bay NERR, MS Great Bay NERR, NH Guana Tolomato Matanzas NERR, FL He'eia NERR, HI Lake Superior NERR, WI Mission Aransas NERR, TX North Inlet-Winyah Bay NERR, SC Old Woman Creek NERR, OH Padilla Bay NERR, WA Sapelo Island NERR, GA Wells NERR, ME place DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2026.
