Strengthening Ocean Acidification Data

 
 
Off of Georgia’s coast is Gray’s Reef National Marine Sanctuary (GRNMS). GRNMS is approximately 17 nautical miles offshore and encompasses 22 square miles of marine protected area that is home to many large invertebrates such as sponges, corals and sea squirts.
 
In 2013, as part of NOAA’s Ocean Acidification (OA) Program, SECOORA received funds to provide support to the GRNMS buoy. The buoy is maintained by the University of Georgia and is part of international efforts to quantify the effects of OA on the world’s ocean. OA is a global change in ocean chemistry resulting from the ocean's uptake of carbon dioxide (CO2), which is increasing in the atmosphere due to the burning of fossil fuels, land use change and more. It is important to measure OA because the increase in CO2 levels can decrease the ocean’s pH, adversely affecting a variety of organisms, particularly those with calcium carbonate shells or skeletons.
 
To date, the GRNMS buoy has been recording high resolution monitoring data for seven years. The sensors on the buoy record pCO2, pH, dissolved oxygen, salinity and water temperature. An overall upward trend has been detected for both seawater and atmospheric pCO2. Seawater pCO2 is increasing on average 2.4% per year and atmospheric pCO2 is increasing on average 0.789% per year.1 The near real time data from the buoy is available on SECOORA’s data portal.

iTAG Workshop

 

The Gulf of Mexico Coastal Ocean Observing System Regional Association (GCOOS-RA) and the Southeast Coastal Ocean Observing Regional Association (SECOORA) co-sponsored an Integrated Tracking of Aquatic Animals in the Gulf of Mexico (iTAG) workshop held May 29-30, 2014. It was hosted and organized by the Florida Fish and Wildlife Research Institute (FWRI) in St. Petersburg, FL. The workshop brought together technologists, scientists, data managers, and administrators from State and Federal government agencies, academic institutions, NGOs, private organizations and international partner Ocean Tracking Network (OTN). The goals of the workshop were to bring together groups involved in animal telemetry, fisheries science and coastal ocean observing in order to: (1) address and advance the science, (2) establish data sharing and exchange policies, and (3) improve coordination and increase spatial infrastructure in the Gulf of Mexico.

The participants discussed the benefits of coordinating animal telemetry efforts in the Gulf. One outcome from the workshop was the consensus to coordinate with GCOOS-RA and SECOORA. The participants agreed to leverage both regional associations coastal observing infrastructures, in particular data management and outreach, in order to establish a web presence for a membership based telemetry group.There was strong agreement to host similar workshops in the future to continue coordinated animal telemetry efforts. A complete workshop report is being complied by Susan Barbieri, FWC/FWRI- for more information please contact Susan via email Susan.Barbieri@MyFWC.com.

 

Wave Heights And Currents in the Florida Straits (WHARF)

SECOORA HF Radar Waves Project Update

In April 2014, Dr. Nick Shay, SECOORA PI from the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science, his graduate student Matthew Archer and the crew onboard the R/V Walton Smith deployed a subsurface mooring in the Straits of Florida.

The mooring is equipped with a NortekUSA acoustic wave and current profiler (AWAC) instrument1. Matthew was a recipient of NortekUSA's Student Equipment Award and was awarded the AWAC to perform the experiment. The AWAC profiler is located at 25.93N and 79.88W in the UM maintained High Frequency (HF) radar footprint (between Dania Beach and Virginia Keys stations) in the Straits of Florida.

It will obtain wave data in order to evaluate the WERA HFR derived significant wave height (SWH) measurements.The AWAC is expected to provide a three month time series. The measurements obtained during the spring and summer transition period will allow proper calibration of the HF Radar wave measurement algorithm.  The data from AWAC, coupled with the HF radar, satellite sea surface temperature and local wind velocity observations will provide a comprehensive four-dimensional (x, y, z, t) dataset to resolve the flow-field evolution at the shelf-break.1The intent is to deliver a quality control index for the extraction of real-time SWH fields for use by the National Weather Service forecasters to evaluate the marine forecasts in the Florida Straits.2  For more information, please contact Nick Shay at lshay@rsmas.miami.edu
