Dr. Leticia Barbero is a chemical oceanographer at NOAA’s Cooperative Institute for Marine and Atmospheric Studies at the University of Miami. In her role, she works with AOML to study the carbon dioxide system in the ocean, specifically ocean acidification in the coastal waters of the U.S. East Coast and Gulf of Mexico.
AOML is deploying drifting buoys as part of a large multinational project that aims to improve our current understanding of the complicated interactions between the air and sea which create shallow convective clouds. NOAA scientists are interested in studying shallow cloud and air-sea interactions because of their influence on global conditions from temperature and precipitation to more extreme weather events.
Existing observations show that Indian Ocean surface water temperatures have been increasing since the 1970’s. But has the deep ocean warmed? Have the regional concentrations of dissolved oxygen, carbon dioxide, or nutrients changed? Has the western Indian Ocean become more acidic? These and more questions will be addressed by scientists after the completion of this cruise.
Collaborative NOAA Research Cruise Studies Role of Ocean Currents in Larval Fish Distribution in Gulf of Mexico and Caribbean
A team of NOAA oceanographers sets sail from Miami aboard the NOAA Ship Nancy Foster on May 7th to investigate ocean currents and fish larvae distribution in the southern Gulf of Mexico and western Caribbean. The joint cruise between NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and Southeast Fisheries Science Center (SEFSC) is a new chapter in a long-term effort that pools cross-line office resources to better understand the early life history and larval recruitment pathways of important fisheries in the region, including the ecologically important and commercially valuable Atlantic bluefin tuna.
During the months of March and April, AOML joined an international team of oceanographers to actively sample the Indian Ocean in support of the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP), an initiative to measure and investigate the ocean basins from coast to coast and from top to bottom. Aboard the R/V Roger Revelle, the team transected the Indian Ocean from the Antarctic northward into the Bay of Bengal, collecting seawater samples at 113 stations as part of a multi-decadal effort to measure various ocean properties, including temperature, salinity, nutrients, carbon and other gases.
When Barack Obama becomes the first president to visit Cuba since Calvin Coolidge, his visit will highlight not only a new course in international relations, but showcase on-going scientific opportunities with the country only 90 miles off the Florida coast.
A team of researchers, including scientists from AOML and the University of Miami, set sail June 19th on a research cruise aboard the NOAA ship Gordon Gunter to provide increased understanding of ocean acidification and its drivers along the U.S. East coast. The cruise, which is part of a larger effort supported by NOAA’s Ocean Acidification Program, investigated near-shore and deep waters, and provided researchers with more detailed information about changing ocean chemistry in different environments.

AOML is partnering with NOAA’s Southeast Fisheries Science Center (SEFSC) to conduct an interdisciplinary research cruise aboard the NOAA Ship Nancy Foster from April 11, 2015 through June 3, 2015. The cruise will begin in the U.S. Virgin Islands and extend westward across the northern Caribbean conducting various biological and physical oceanographic surveys.
