Early on the morning of August 29th, 2005, Hurricane Katrina made landfall on the Louisiana delta region and the Mississippi coast. The storm surge brought enormous damage to the Gulf Coast and, when the levees around New Orleans failed, a great number of fatalities. Coming amidst the very busy 2005 hurricane season, Katrina brought death and destruction not seen in a U.S. land-falling hurricane in decades.
Photos taken from NOAA’s P-3 aircraft during Hurricane Hunter flights conducted on Saturday, August 22nd and Sunday, August 23rd inside Hurricane Danny. Peaking at Category 3 strength on Friday, August 21, Danny had maximum sustained winds of 115 mph as it churned in the Atlantic. Danny then weakened to a tropical depression due to interaction with high levels of wind shear and a mass of dry air in the Caribbean as it moved across the Lesser Antilles. The Hurricane Hunter missions profiled Danny’s wind structure with Tail Doppler Radar, conducted various projects in support of the Hurricane Research Division’s 2015 Field Program, and surveyed the ocean ahead of the storm in order to improve forecasts.
Scientists from NOAA and the Cooperative Institute for Marine and Atmospheric Studies at the University of Miami have documented a dramatic shift from vibrant coral communities to carpets of algae in remote Pacific Ocean waters where an undersea volcano spews carbon dioxide.
With the 2015 Atlantic hurricane season underway, researchers are pointing to the strong presence of El Niño as the major driver suppressing the development of tropical cyclones in the Atlantic basin. But what specific conditions are associated with El Niño that lead to a less than ideal environment for tropical cyclone development? Through research and observation, hurricane researchers know strong environmental wind shear is a major factor affecting potential hurricane development and growth. This hurricane season, AOML researchers are delving further into the relationship between wind shear and tropical cyclones.
AOML welcomes 22 young men and women, including new and returning high school, undergraduate, and graduate students, who are completing internships at the lab this summer. Over the course of their six to ten week internships, students will work with mentors in the fields of Ocean Chemistry & Ecosystems, Physical Oceanography, and Hurricane Research, as […]
The pathways of recently ventilated North Atlantic Deep Water (NADW) are part of the lower limb of the Atlantic Meridional Overturning Circulation (AMOC). In the South Atlantic these pathways have been the subject of discussion for years, mostly due to the lack of observations. Knowledge of the pathways of the AMOC in the South Atlantic is a first order prerequisite for understanding the fluxes of climatically important properties.
A team of scientists from NOAA’s AOML and Southeast Fisheries Science Center have conducted a series of surveys in Florida Bay this year as part of an ongoing project to investigate how juvenile sport fish in the bay respond to changes in water quality and habitat resulting from Everglades restoration. During the survey, scientists collected water quality and seagrass measurements and conducted otter trawls to sample the juvenile sport fish populations.
On July 14th, 2015, AOML physical oceanographers deployed one of two sea gliders in the Caribbean from the University of Puerto Rico’s R/V La Sultana. The third deployment will continue the project’s mission to gather important data in the Caribbean and Tropical North Atlantic Ocean to help with hurricane intensity forecasting and provide valuable information about the role the ocean plays in tropical cyclone development. What’s new for this mission? For the first time, the gliders will collect ocean current velocity profiles in addition to the real-time temperature, salinity, and oxygen data. AOML scientists also equipped the glider with an improved battery which will allow the glider to record more profile measurements. The second of the two gliders will be deployed in the Tropical North Atlantic in the upcoming weeks.
AOML physical oceanographers and interns conducted a hydrographic survey along the 27th north parallel in the Florida Straits aboard the R/V F.G. Walton Smith on July 14-15 as a component of the Western Boundary Time Series project. These 2-day cruises are designed to calibrate daily estimates and quantify Florida Current volume transport and water mass changes.
