  2. Acknowledgements • Hard work of a lot of people • Allizon Mojzis (nutrients) • Xiaogang Chen (optics) • Sumit Chakraborty (pigments) • Adam Boyette, Luz Molina, Matthew Stone, Ashley Lojek, Merritt Tuel (sampling and technical assistance) • Funding provided by NOAA (NGI, CenGOOS) and NASA

  3. Overview • Approach • Sampling Locations • Preliminary Results • Future Plans

  4. Approach • Monthly cruises from St. Louis Bay out to USM buoy site 10 km south of Horn Island • Additional stations occupied near mouth of East Pearl River

  5. Approach • Profiles of variables included: • Temperature • Salinity • Depth • Dissolved Oxygen • Optics (selected stations) • At selected stations and depths: • Nutrients • Trace metals • CDOM, DOC, DON • Pigments • Particulate Absorption • Total Suspended Matter

  6. Pearl River St. Joe Henderson Pt. • Sampling locations on April 14 ‘+’ and 17 ‘o’ • MODIS Aqua enhanced true color image from April 15

  7. Sampling locations on May 19 ‘+’ and 20 ‘o’ • MODIS Aqua enhanced true color image from May 19 (spillway closed since May 8)

  8. Preliminary Results

  9. Future Plans • Additional sampling planned on monthly basis • Complete analyses of water quality variables: • Nutrients • CDOM • Pigments • TSM • Particulate absorption
