PNAS Writer Follows Scientists Seeking to Answer, Did Sub-Sea Dispersants Work?

July 18, 2019

July 18, 2019 Scientist and author M. Mitchell Waldrop accompanied researchers, funded by the Gulf of Mexico Research Initiative, as they conducted the largest experimental simulation to-date of the Deepwater Horizon oil intrusion. The researchers are hoping to provide solid science on dispersant effectiveness so that more informed decisions can be made when the next […]

Study Improves Drifter-Based Estimates of Near-Surface Ocean Currents

July 10, 2019

July 10, 2019 Using 40 years of observations from the NOAA’s Global Drifter Program Array, the authors depict the annual mean speed of ocean currents at 15 meters depth. The vectors highlight the general direction of the large-scale circulation. Image provided by Lucas Laurindo, University of Miami Rosenstiel School of Marine and Atmospheric Science. Scientists […]

Grad Student Grossi Uses Artificial Intelligence to Map Ocean Flows

June 11, 2019

June 11, 2019 Our knowledge about ocean transport comes primarily from ocean circulation models that use field observations and theoretical motion equations to simulate ocean dynamics. Ocean models can depict large-scale circulation features accurately, but resolutions high enough to capture all scales of motion entail significant computational time and cost and are challenging or even […]

Study Compares 2D and 3D Model Simulations of Oil Plume Behavior

June 4, 2019

June 4, 2019 Scientists assessed an economical 2D model simulation of deep-ocean oil plume dynamics against 3D model results using conditions similar to Deepwater Horizon to better understand point-source buoyant convection, which affects the oil’s spreading rate and environmental impact. The 2D model worked best for thermal plumes without bubbles. Although the 2D model successfully […]
