Rewriting the Climatology of the Tropical North Atlantic and Caribbean Sea Atmosphere

Dunion, J.P., 2011: Re-writing the climatology of the tropical North Atlantic and Caribbean Sea atmosphere. J. Climate, 24(3), 893-908, doi:10.1175/2010JCLI3496.1

Abstract: The Jordan mean tropical sounding has provided a benchmark reference for representing the climatology of the tropical North Atlantic and Caribbean Sea atmosphere for over 50 years. However, recent observations and studies have suggested that during the months of the North Atlantic hurricane season, this region of the world is affected by multiple air masses with very distinct thermodynamic and kinematic characteristics. This study examined ;6000 rawinsonde observations from the Caribbean Sea region taken during the core months (July–October) of the 1995–2002 hurricane seasons. It was found that single mean soundings created from this new dataset were very similar to C. L. Jordan’s 1958 sounding work. However, recently developed multispectral satellite imagery that can track low- to midlevel dry air masses indicated that the 1995–2002 hurricane season dataset (and likely Jordan’s dataset as well) was dominated by three distinct air masses: moist tropical (MT), Saharan air layer (SAL), and midlatitude dry air intrusions (MLDAIs). Findings suggest that each sounding is associated with unique thermodynamic, kinematic, stability, and mean sea level pressure…

Scientists Use 3D Printing Technology to Study Water Chemistry at Coral Reefs

AOML researchers have taken an innovative approach to studying the changing carbonate chemistry of seawater at shallow coral reef sites. Using 3D printing technology made possible by the new Advanced Manufacturing and Design Lab at AOML, researchers with the Acidification, Climate, and Coral Reef Ecosystems Team, or ACCRETE, have created a water sampler in-house.

New Cruise Studies Red Tide Impacts in South Florida

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.

Dominance of the Geostrophic and Ekman Transports on the MOC in the South Atlantic

The Meridional Overturning Circulation (MOC) plays a critical role in global and regional heat and freshwater budgets. Recent studies have suggested the possibility of a southern origin of the anomalous MOC and meridional heat transport (MHT) in the Atlantic, through changes in the transport of warm/salty waters from the Indian Ocean into the South Atlantic basin. This possibility clearly manifests the importance of understanding the South Atlantic MOC (SAMOC). Observations in the South Atlantic have been historically sparse both in space and time compared to the North Atlantic. To enhance our understanding of the MOC and MHT variability in the South Atlantic, a new methodology is recently published to estimate the MOC/MHT by combining sea surface height measurements from satellite altimetry and in situ measurements (Dong et al., 2015).

AOML Selects Coral Researcher, Jim Hendee, to Lead Ocean Chemistry & Ecosystems Research

AOML is proud to announce the selection of Dr. James “Jim” Hendee as the director of its Ocean Chemistry and Ecosystems Division. Internationally recognized for his expertise in coral observing systems and data management, Jim’s almost 25-year tenure with AOML began in 1990 as a data manager for several ocean chemistry programs. Jim is well known for his ability to leverage resources to innovatively develop and inspire productive research teams. Jim steps into the role of director after serving in an acting capacity since June 2013.
