Scientists conducted genetic sequencing on bacteria to document the oil-associated groups in sediment affected by marine oil snow post-Deepwater Horizon. The researchers observed increases in bacteria that degrade aerobic Polycyclic Aromatic Hydrocarbons (PAHs) and anaerobic sulfate-reducing bacteria in sediment collected from September-November 2010. Aerobic bacteria likely used oxygen rapidly when consuming PAHs and caused localized Read More

GoMRI ScienceResearch Stories CARTHE Blog Highlights Drones Used in SPLASH Experiment 4468

CARTHE researchers relied on high-resolution cameras mounted to drones to track drift cards’ initial transport during the SPLASH experiment to measure currents. The acquired images are used to see how small scale surface currents behave, especially around fronts. The GPS-equipped LASER drifters collect data for 2-4 months over many kilometers, while the drones allow CARTHE Read More

Approximately 15 local fishermen and their families attended the workshop to meet the scientists and voice their concern about topics such as sediment and marine snow. The fishermen also learned how to use the YSI ProDSSII conductivity/temperature-depth meter (CTD) to collect depth salinity and temperature profiles. They will continue collecting and returning data through the Read More

Scientists tested a new analytical method for a fast and comprehensive characterization of organic compounds in marine sediments. The Rapid Analyte Detection and Reconnaissance (RADAR) method couples atmospheric pressure photoionization in positive ion mode (APPI-P) with Fourier transform ion cyclotron mass spectrometry (FTICR-MS). Twelve minutes of analysis provided a simultaneous detection and identification of thousands Read More

Scientists examined Red Snapper and Spanish Mackerel larvae before, during, and after the Deepwater Horizon oil spill to determine if and how the spill may have affected them. The researchers observed that Red Snapper larvae were in poorer condition during and after the spill compared to pre-spill metrics, which may affect lifetime growth and fitness. However, this Read More

GoMRI SciencePublication Highlights Study Investigates Influence of Hurricanes on Ocean Surface Currents Hurricane Isaac from August 26 – 31, 2012 and GLAD drifter trajectories (thin black and red lines) during the same time period. More details about this image are available in the publication, Figure 1. Image provided by Shuyi S. Chen, Rosensteil School of Marine and Atmospheric Sciences, University of Miami.

Scientists used GPS data collected from ocean drifters during Hurricane Isaac with a coupled atmosphere-wave-ocean model to better understand how hurricanes affect upper ocean circulation. The researchers found that hurricane-induced Stokes drift (wind-wave-driven water mass transport) created a cyclonic rotational flow to the storm’s left and an anticyclonic rotational flow to its right. Stokes drift Read More

GoMRI StudentsPeople Meet C-IMAGE Student of the Month Katelyn Knight 4436

The role of microbial communities during oil spills gets a bit of attention due to their role in biodegradation of oil and dispersants. Since 2010, research have discovered that dispersed oil inhibits growth of certain bacteria strains, and biodegradation occurs in different phases depending on the weathering of the oil. Katelyn Knight looks to make Read More
