An enhanced PIRATA data set for tropical Atlantic ocean-atmosphere research

AOML oceanographers, Greg Foltz, Claudia Schmid, and Rick Lumpkin released a new and enhanced set of daily time series for the tropical Atlantic upper ocean temperature, salinity, and velocity, and standard meteorological fields. This new dataset (ePIRATA) is fully described in the newly accepted paper in Journal of Climate and can be accessed through ePIRATA homepage. Full story>>


Ocean dynamics played key role in Antarctic sea ice changes during past decades

AOML Oceanographer Sang-Ki Lee and his colleagues used an ocean and sea-ice coupled model to show that ocean dynamics played key role in Antarctica's sea ice changes during past decades. This research* was selected as an Editor's highlight for the Journal of Geophysical Research. Full story>>


Underwater Glider Data Improved Intensity Forecasts of Hurricane Gonzalo

In a recent study published in Weather and Forecasting,* AOML researchers and their colleagues used NOAA's HWRFHYCOM operational hurricane forecast model to quantify the impact of assimilating underwater glider data and other ocean observations into the intensity forecasts of Hurricane Gonzalo (2014).

Project Explores Deep Ocean Heat Accumulation in the South Pacific

One of the most challenging questions in global climate change studies today is how quickly, or if, heat that accumulates within the Earth system penetrates into the deep ocean. Scientists with the University of Miami (UM), AOML, and NASA's Jet Propulsion Laboratory (JPL) recently tackled this question by using a combination of present-day satellite and in situ observing systems to study the distribution of heat in the oceans.

Remote influence of Interdecadal Pacific Oscillation on the South Atlantic meridional overturning circulation variability

This study explores potential factors that may influence decadal variability of the South Atlantic meridional overturning circulation (SAMOC) by using observational data as well as surface-forced ocean model runs and a fully coupled climate model run. Full story>>


Global Characteristics of Coherent Vortices from Surface Drifter Trajectories

In a recent study by Lumpkin (2016) looping trajectories of surface drifting buoys were extracted from the global drifter dataset and analyzed in order to examine the distribution of submesoscale to mesoscale vortices. Over 15,000 looping trajectory segments were identified worldwide. Full story>>
