The global mean sea level rise caused by ocean warming and glacier melting over landforms such as Greenland is one of the most alarming aspects of a shifting global climate. However, the dynamics of the ocean and atmosphere further influence sea level changes region by region and over time. For example, along the U.S. East Coast, a pronounced acceleration of sea level rise in 2010-2015 was observed south of Cape Hatteras, while a deceleration occurred up North. These patterns provide background conditions, on top of which shorter-period (and often stronger) weather-driven sea level fluctuations compound what coastal communities directly experience day by day. Therefore, to develop or improve regional sea level predictions, it’s important to identify these patterns and explore how they change over time.
New Study Shows Atlantic Meridional Overturning Circulation and Mediterranean Sea Level are Connected
The new research published by NOAA and international partners in Science finds as carbon dioxide emissions have increased in the atmosphere, the ocean has absorbed a greater volume of emissions. Though the volume of carbon dioxide going into the ocean is increasing, the percentage of emissions — about 31 percent — absorbed by it has remained relatively stable when compared to the first survey of carbon in the global ocean published in 2004.
Frank Marks, Sc.D. honored with the OAR Dr. Daniel L. Albritton Outstanding Science Communicator Award
The National Oceanic and Atmospheric Administration’s Oceanic and Atmospheric Research Dr. Daniel L. Albritton Outstanding Science Communicator Award recognizes outstanding achievement in communicating the meaning and value of NOAA-related science and research to non-scientific audiences. The award is named in honor of Dr. Daniel L. Albritton, a retired OAR scientist, who proved to be one of the most effective communicators of NOAA research and related science.
AOML hurricane researchers supported nearly all of the 50 missions NOAA’s Hurricane Hunter aircraft flew into eight tropical systems in 2018’s hurricane season, collecting data to help improve forecasts for future storms. The final flight into Hurricane Lane would make history for several reasons. Hurricane Lane was part of NOAA’s first hurricane deployment out of Hawaii, and one of those flights was led by the first all-female science crew on the flying laboratory. For Women’s History Month, we are proud to highlight this milestone and recognize the members of the first all-female science crew on a hurricane flight.
AOML recently led a multi-agency (NOAA/AOML, NOAA/SEFSC, State of Florida Fish and Wildlife Research Institute, Florida Fish and Wildlife Commission, NOAA/NESDIS, University of South Florida, MOTE Marine Laboratory and Aquarium, and University of Miami) research cruise to study the effects of Southwest Florida’s ongoing red tide. To address such a complex problem as red tide, the cruise brought together a diverse team of experts consisting of commercial fishermen, oceanographers, systems ecologist, phytoplankton ecologist, and fish population biologist. This cruise allowed researchers to take a holistic approach to characterize the extent of the red tide and its impacts. The goal of the cruise was to understand why these blooms happen to better inform effective future response measures and hopefully improve Florida’s resilience to these coastal events.
Few accessible places represent Earth’s natural beauty quite like our beaches, but looks can be deceiving if there is a bacterial outbreak or contamination from offshore activities. Not being able to see these contaminants puts families at risk of exposure if they aren’t properly warned. The BEACHES project (Beach Exposure And Child Health Study), a collaboration between the University of Miami’s College of Engineering and the Cooperative Institute for Marine and Atmospheric Studies and AOML, along with the Universities of Arkansas and Texas, aims to pair child behavioral science with microbiology to address exposure risk of beachgoers.
AOML drives improvements to hurricane forecasts by leveraging expertise in tropical cyclone observations, research, and modeling. Our numerical weather modeling team uses HWRF to test new technology and advance hurricane prediction through data collection, assimilation, and experimental modeling.
In August 2018, a team of biological oceanographers and ecologists set sail on the R/V Walton Smith to sample the waters of Biscayne Bay & Florida Bay. AOML has conducted regular interdisciplinary observations of south Florida coastal waters since the early 1990’s. We spoke with Chris Keble, the lead scientist for AOML’s South Florida Ecosystem Restoration Research project, to learn more.
NOAA will soon launch a fleet of 15 unmanned gliders in the Caribbean Sea and tropical Atlantic Ocean this hurricane season to collect important oceanic data that could prove useful to forecasters. “If you want to improve prediction of how hurricanes gain strength or weaken as they travel over the ocean, it’s critical to take the ocean’s temperature and measure how salty it is,” said Gustavo Goni, an oceanographer at NOAA’s Atlantic Oceanographic and Meteorological Laboratory who is helping lead the glider research. “Not just at the surface, which we measure with satellites, but down into deeper layers of ocean waters.”
NOAA contributed to a study published today in the journal Nature that compares the upward growth rates of coral reefs with predicted rates of sea-level rise and found many reefs would be submerged in water so deep it will hamper their growth and survival. The study was done by an international team of scientists led by the University of Exeter in the United Kingdom.
