USGS Researchers publish paper on Florida estuary acidification using 20+ years of data from shellfish industry

USGS researchers Lisa L. Robbins (retired) and John T. Lisle (Research Microbiologist, SPCMSC) published an article, 'Regional Acidification Trends in Florida Shellfish Estuaries: a 20+ Year Look at pH, Oxygen, Temperature, and Salinity,' in Estuaries and Coasts. In the article pH, dissolved oxygen, temperature, and salinity data from 10 Florida shellfish estuaries and shellfish bed stations are compared. Over 80,000 measurements, spanning from 1980 to 2008, taken on Atlantic Ocean and West Florida coast sites showed significant regional trends of consistent pH decreases in 8 of 10 estuaries. Other significant trends include decreasing dissolved oxygen in 9 of 10 estuaries, increasing salinity in 6 of 10, and temperature increases in 3 of 10 estuaries. The data provide a synoptic view of Florida estuary trends, which reflect the complexity of changing climate and coastal ocean acidification. These data provide context for understanding, and interpreting the past and predicting future of regional water quality health of shellfish and other organisms of commercial and ecological significance along Florida's coasts.

USGS Researchers Attend the Florida Coastal Mapping Program Workshop

Research scientists from multiple agencies and universities will participate in developing a strategy for mapping all of Florida's coastal waters during a 3-day workshop in St Petersburg. The USGS and the Florida Institute of Oceanography spearheaded an effort to bring multiple federal and state agencies and stakeholders together to develop a strategy to map all of Florida's coastal waters, from the shoreline to 200 m water depth, over the coming decade. A year-long effort to assess existing data and undertake a gap analysis will culminate in a 3-day workshop Jan 9–11, 2018, to be held at the Florida Wildlife Research Institute in St Petersburg, Florida. A staffer from Representative Crist's office will be providing opening remarks and plans to attend the entirety of the workshop. Cheryl Hapke, Xan Fredericks, Jim Flocks, Jen Miselis, and Stan Locker from the SPCMSC will be participating, along with invited speaker Sam Johnson (PCMSC), and Jeff Danielson from the EROS Data Center. The technical team engaged in the effort include NOAA, BOEM, USACE, FIO, FWRI, FL DEP, USF College of Marine Science, NOVA Southeastern University, U. Miami Rosenstiel School of Marine & Atmospheric Science, and Florida Atlantic University.
