This project deployed seven new temperature loggers in the Flower Garden Banks region and the U.S. Caribbean, in order to extend the vertical range of present monitoring studies associated with Coral Reef Watch. The loggers were deployed over the side of the boat or with an ROV in a low-relief area with few obstructions. The loggers will be recovered using an ROV or burn wire releases. Temperature data will be downloaded and plotted for reports, then uploaded to public repository at NOAA Coral Reef Watch website.
The SEDCI ocean acidification project deployed a CTD-rosette to 1500 m depth for a series of water column profiles at intervals on the order of 5, 25, 50, 100, 150, 250, 500, 1000, 1500 m depth aboard the NOAA Ship Nancy Foster expedition in August 2017. Samples were also opportunistically collected aboard the NOAA Ship Okeanos Explorer in 2018 and 2019. Water samples were shipped following established safety guidelines by the United States Geological Survey (USGS) for water chemistry measures, working in coordination with Southeast Ocean and Coastal Acidification Network (SOCAN).
A workshop held by SOCAN in March 2017 established shellfish (primarily oysters), shallow and deep coral reefs as key species for environmental monitoring of aragonite saturation in marine environments. The SOCAN workshop specifically identified a need to collect water samples directly adjacent to cold-water scleractinian corals. This was identified as the top priority for deep-sea corals. Sampling at Lophelia pertusa reefs (300-800 m depth) and Oculina vericosa reefs (~80-100 m) off the coast of Melbourne, FL and near the Gulf Stream were a priority. Water and biological samples were collected using the ROV Deep Discoverer aboard the NOAA Ship Okeanos Explorer. Dr. Kim Yates (USGS) provided supplies needed for water sampling, including chemicals, and analyzed samples for carbonate chemistry. Through this SEDCI project, aragonite saturation data will be downloaded and plotted for reports and then uploaded to public repository at AOML. The project partnered with the NOAA Ocean Acidification program, SOCAN, and others, in order to leverage additional resources and accomplish shared goals.
