AOML scientists are collaborating with partners from the Northern Gulf Institute of the University of Mississippi, and the University of Miami’s Cooperative Institute for Marine and Atmospheric Studies to tackle increasing nutrient levels throughout Biscayne Bay. A previous study detected the slow but steady eutrophication and warned of a regime shift towards murky algal dominated waters if better water quality management practices were not implemented.
The 2019 Atlantic hurricane season ended on November 30 but not before churning out 18 named storms, including catastrophic Hurricane Dorian. Throughout the season, AOML’s hurricane scientists were at the forefront of NOAA’s efforts to prepare vulnerable communities for severe weather.
Scientists are now looking to expand their observing capabilities to include the biology and chemistry of the oceans, currently available globally from ocean color satellites that measure chlorophyll, indicating algal blooms at the ocean surface. A recent paper in the Journal of Atmospheric and Oceanic Technology by AOML postdoctoral scientist Cyril Germineaud of the University of Miami’s Cooperative Institute for Marine and Atmospheric Studies and colleagues shows that in close synergy with ocean color satellites, a global array of biogeochemical sensors complementing the existing core Argo network could revolutionize our knowledge of the changing state of primary productivity, ocean carbon cycling, ocean acidification, and the patterns of marine ecosystem variability from seasonal to interannual time scales.
The ways in which Sargassum has invaded the tropical Atlantic have been a mystery, but we may now have an answer. A new study in Progress in Oceanography, led by researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML), identifies possible mechanisms and pathways by which Sargassum entered and flourished in the tropical Atlantic and Caribbean.
NOAA is turning 50! The federal science agency that provides daily weather forecasts, severe storm warnings, fisheries management, and coastal restoration, is celebrating by opening its doors to the south Florida community with a free open house on April 25th, 2020 from 10:00 a.m to 3:00 p.m. What better way to celebrate Earth Day than seeing science in action with friends and family!
TACOS has added 10 acoustic current meters to the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) buoy, moored at 4N, 23W. Profile measurements are taken every 1-10 minutes, depending on depth. Prior to the addition of the TACOS upper ocean observations in March 6, 2017 velocity profiles were only collected at this location during shipboard surveys. These measurements are important because ocean currents influence temperature, salinity, and air-sea fluxes in the tropical North Atlantic, which affect weather, climate, and fisheries of the surrounding continents.
Every year the Global Carbon Project publishes an authoritative observation based Global Carbon Budget detailing the annual release of fossil fuel carbon dioxide and the uptake by the terrestrial biosphere and oceans. In 2018 the global carbon emissions were still increasing, but their rate of increase had slowed. Global carbon emissions are set to grow more slowly in 2019, with a decline in coal burning offset by strong growth in natural gas use worldwide.
The ability to predict Earth’s future climate relies upon monitoring efforts to determine the fate of carbon dioxide emissions. For example, how much carbon stays in the atmosphere or becomes stored in the oceans or on land? The oceans in particular have helped to slow climate change as they absorb and then store carbon dioxide for thousands of years.
AOML’s hurricane scientists conducted multiple airborne missions into several tropical systems that formed in the Atlantic in September and October. The data gathered in Humberto, Jerry, pre-Karen, Lorenzo, and Nestor improved track and intensity forecasts, aiding NOAA’s efforts to prepare vulnerable communities for severe weather. The missions also supported research to better understand how tropical cyclones form, intensify, and dissipate, as well as supported efforts to validate satellite measurements of these storms.
November 19 – 21, 2019, AOML hosted a three day external review to evaluate the quality, performance, and relevance of our research portfolio. NOAA’s Office of Oceanic and Atmospheric Research conducts these reviews every five years to gauge the effectiveness of the research portfolios of all the labs, and also to forge new partnerships for research and collaborations across NOAA. Feedback received after the completion of the lab review will help set new priorities for AOML. The 2019 AOML review featured presentations from each science division, lightning talks from scientists, a poster session, lab tours, and an early career luncheon. We also had the pleasure of hosting Deputy NOAA Administrator Rear Admiral Tim Gallaudet at the opening of the review.
