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.

King Tide: tide at 10:30am shows high watermark on a bridge in Coconut Grove

Research Fit for a King Tide

The colloquial term ‘king tides’, referring to the highest astronomical tides of the year, is now part of most Miami Beach residents and city managers’ vocabulary. Exacerbated by rising seas, these seasonal tides can add up to 12 inches of water to the average high tide, threatening the urbanized landscape of Miami Beach. During these events, AOML’s Microbiology Team is on the scene to investigate these tidal waters as they rise and recede. The microbiologists are part of a research consortium for sea level rise and climate change, led by Florida International University’s Southeast Environmental Research Center. The research effort focuses on collecting samples and monitoring water quality at locations along the Biscayne Bay watershed where the City of Miami Beach has installed pumps to actively push these super-tidal floodwaters back into the bay.
