Scientists used 3D regional ocean model simulations and sediment trap data to investigate how large (mesoscale) and small (submesoscale) circulations affect the transport of sinking particles, or marine snow, in the northern Gulf of Mexico. Small-scale convergence and divergence processes (a few kilometers) and cross-shore transport of riverine inputs induced by mesoscale eddies significantly influenced the speed and trajectory of sinking particles in offshore waters.
The Smithsonian’s Ocean Portal published an article that describes how oysters (that filter up to 50 gallons of water a day) fare under hazardous environmental conditions.
Scientists developed a modeling framework that includes small-scale fluid dynamics to investigate how dispersant application during Deepwater Horizon may have affected oil biodegradation and the environment.
The Gulf of Mexico Research initiative (GoMRI) congratulates Dr. Antonietta Quigg for her distinction of Regents Professor of Marine Biology and Oceanography at Texas A&M University.
Researchers combined detailed observations, laboratory experiments, and existing numerical models to develop the Texas A&M Oil Spill (Outflow) Calculator (TAMOC) and improve predictions of subsea oil and gas plume dynamics.
Scientists developed a two-stage algorithm that identified the status of drogues attached to ocean drifters deployed during the Lagrangian Submesoscale Experiment (LASER).
Many fish that were exposed to Deepwater Horizon oil survived; however, they may have experienced later-in-life impacts that affected their ability to survive longer than fish that did not experience oil exposure.
Researchers conducted mesocosm experiments that simulated beach ecosystems to assess if razor clams, which are bioturbators, can influence environmental conditions and the fate of polycyclic aromatic hydrocarbons (PAHs).
During the Deepwater Horizon incident, some models predicted that oil would reach the Florida coastline. However, much of the oil became trapped in cyclonic-like currents, which are eddy flows associated with the Loop Current, and exited the Gulf of Mexico without reaching the Florida coast.
Researchers provided some of the first descriptions of the feeding habits of eight deep-sea fishes using dietary tracers (stable isotopes), offering insight into the trophic structure of deep-sea ecosystems and informing ecosystem-based modeling.
