Numeric Nutrient Criteria Study Cruise

AOML scientists conducted a Numeric Nutrient Criteria Study cruise Wednesday and Thursday, March 18-19th in Biscayne Bay off of Broward and Miami-Dade Counties aboard the NOAA R/V Hildebrand. The study provides concurrent water column and coral reef status data for four coral assemblies off of Miami-Dade and Broward County. These results will be employed by the Florida Department of Environmental Protection to determine numeric nutrient criteria for the coastal waters of Southeast Florida.

Gulf of America Marine Food Web Changes Over the Decades

Scientists in the Gulf of America now have a better understanding of how naturally-occurring climate cycles–as well as human activities–can trigger widespread ecosystem changes that ripple through the Gulf food web and the communities dependent on it, thanks to a new study published Saturday in the journal Global Change Biology.

NOAA Selects Biscayne Bay for Next Habitat Blueprint Focus Area

NOAA has selected South Florida’s Biscayne Bay as one of the next Habitat Focus Areas under NOAA’s Habitat Blueprint. Habitat Blueprint offers opportunities for NOAA to partner with organizations to address coastal and marine habitat loss and degradation issues. It provides a framework, which builds upon existing programs, prioritizes activities, and helps users act strategically and preventively [...]

Hydrographic Survey Conducted in the Florida Straits

PhOD personnel Ryan Smith, Grant Rawson, and Jay Hooper conducted a hydrographic survey along 27N in the Florida Straits aboard the R/V F.G. Walton Smith on January 12-13, 2015. The cruise was part of the Western Boundary Time Series project, which is designed to quantify Florida Current volume transport and water mass changes. This survey and others help to calibrate daily estimates of the Florida Current volume transport derived from a submarine telephone cable deployed across the Straits. Divers also exchanged a project pressure gauge on the west side of the 27N section.

Hydrographic Survey Conducted in the Florida Straits

Ryan Smith, Robert Roddy, and Jay Hooper conducted a hydrographic survey along 27N in the Florida Straits aboard the R/V F.G. Walton Smith December 11-12, 2014. The cruise was performed as part of the Western Boundary Time Series project, which conducts regular surveys such as this to quantify Florida Current volume transport and water mass changes in the Straits of Florida. This survey and others also help to calibrate daily estimates of the Florida Current volume transport derived from a submarine telephone cable deployed across the Straits.

Waterways Program Features the Impacts of Ocean Acidification on Coral Reefs

The latest episode of the educational television series “Waterways” features coral research conducted by NOAA scientists in the Florida Keys. As the global ocean becomes more acidic, NOAA is documenting these changes and their impact on organisms like corals. The first part of the episode entitled “Ocean Acidification & Tortugas Tide Gauge”   features AOML [...]

Living Oceans Foundation Global Reef Expedition

AOML coral scientists Renee Carlton participated in the Living Oceans Foundation Global Reef Expedition to the Solomon Islands from October 27, 2014 through November 25, 2014. Carlton collected seawater carbon dioxide data and coral cores for calcification analysis as part of the ongoing collaboration between the Living Oceans Foundation and AOML to obtain baseline ocean acidification-related data from remote coral reef locations across the Pacific Ocean.

NOAA Partners Join CalCofi to Examine the Potential of ‘Omics Research

NOAA’s Atlantic Oceanographic and Meteorological Laboratory is teaming up with NOAA’s Office of Ocean Exploration and Research, National Marine Fisheries Service, and Integrated Ocean Observing System, as well as the J.C. Venter Institute and the Scripps Institution of Oceanography to enhance ecosystem observation programs by integrating genome-enabled techniques and technologies (i.e., ‘omics) into the California Cooperative Oceanic Fisheries Investigations (CalCOFI). CalCOFI is a multi-partner, long-term ecosystem and fisheries study off the coast of California. The first quarterly CalCOFI expedition that included ‘omics recently completed at the end of November.

The Central Caribbean Marine Institute (CCMI) Redeploys Coral Reef Early Warning System (CREWS) Buoy

During the month of October, the Central Caribbean Marine Institute (CCMI) finished redeploying their buoy, which is part of the Coral Reef Early Warning System (CREWS). The buoy was first deployed in October 2013 and needs to be returned to land each year for cleaning, repainting and instrumentation swap. The buoy was towed from its deployment site on October 14th and returned to position on October 29th. AOML’s Mike Jankulak worked remotely with CCMI personnel to update the buoy’s programming and develop procedures for instrument configuration. As of October 31st all data feeds from the buoy to AOML and NDBC has fully resumed.
