Marine oil snow is the largest commuter of carbon to the seafloor and occurs when oil and marine particles aggregate and sink through the water column. Previous studies show that oil and dispersant significantly increased marine microorganisms’ production of exopolymeric substances (EPS), an extremely sticky goo that holds marine snow together. Maya Morales-McDevitt conducts mesocosm experiments investigating how certain Read More

They will continue collecting and returning data through the Read More

ECOGIG • GoMRI Students • People • Grad Student Girard Uses High-Definition Imagery to Assess Post-Spill Coral Recovery 4014a

Deep-sea corals are important organisms that support a healthy and diverse deep-sea ecosystem. However, there is much we do not know about certain coral species, including how they grow, reproduce, or interact with other organisms. Fanny Girard’s research helps bridge that knowledge gap through her work on how disturbances such as oil spills affect deep-sea Read More

CONCORDE • GoMRI Students • People • Grad Student Dykstra Sees Global Applications for Local Ocean Circulation Maps 4031a

When Deepwater Horizon oil approached coastal environments, it was unclear how river water entering the Gulf of Mexico would affect the oil’s transport and fate. Steve Dykstra uses drifters and ship-deployed sensors to study how freshwater plumes disperse in the coastal environment over different seafloor topography. He plans to someday use his findings and experience Read More

GoMRI Students • People • RECOVER • Grad Student Diamante Investigates How PAHs Affect Fish Development 4084a

Polycyclic aromatic hydrocarbons (PAHs) can disrupt important signaling pathways that transcribe genes during fish’s early embryonic development, which could cause malformations. Graciel Diamante is conducting laboratory experiments with fish embryos to understand how weathered PAHs affect fish development. She is also finding that her work demonstrates the importance of perseverance, giving back, and collaborating within Read More

CONCORDE • GoMRI Students • People • Grad Student Quas Analyzes Sediment Grain Size to Characterize Oil Behavior 3915a

Oil droplets can attach to tiny sediment particles suspended in the water column, causing them to sink to the seafloor where they can linger for a long time. Sediment grain size influences if and how oil droplets are resuspended into the water column. Larger particles sink faster and are more difficult to resuspend in the Read More

CWC • GoMRI Students • People • How Grad Student Cui Uses River Diversion Models to Inform Oil Spill Remediation 3831a

When oil from the Deepwater Horizon spill began approaching land, one proposed response was to divert Mississippi River water and sediment into the marshes to try and push surface oil more towards the Louisiana-Texas shelf. Linlin Cui is investigating the impacts of Mississippi River diversions on Barataria Bay hydrodynamics to help inform how future oil Read More

ACER • GoMRI Students • People • How Grad Student Seubert Interprets Gulf of Mexico Resiliency Using Predator Diet 3820a

Major environmental disturbances such as oil spills can alter a marine ecosystem’s structure and even cause species losses or additions in impacted areas – changes which may have long-term consequences for an ecosystem’s functions. Emily Seubert investigates the diets of marine predators in the northern Gulf of Mexico food web to better understand how the Read More

GoMRI Students • People • RECOVER • Grad Student Pasparakis Looks to Fish Embryos for Long-Term Oil Spill Answers 3739a

Studies that investigate the effects of oil exposure on developing fish are typically conducted at otherwise non-stressful ambient conditions, which may result in conservative impact estimates. Christina Pasparakis is studying the combined effects of oil exposure and other environmental stressors to create a more comprehensive assessment of Deepwater Horizon impacts. Christina is a marine science Read More

CRGC • GoMRI Students • People • Grad Student Fiore Investigates Oil Spill Impacts on Gulf Economy and Fisheries Resiliency 3719a

Natural and manmade disasters often involve long-term effects, but the majority of follow-up research tends to focus on the biophysical impacts rather than the social. Jacqueline Fiore, a Louisiana resident, understands how disasters such as hurricanes and oil spills can impact local industries, citizens, and ecosystems. Jacqueline, a Ph.D. student in Tulane University’s Economic Analysis Read More

There are hundreds of deep-pelagic fish species in the Gulf of Mexico, but we know very little about their taxonomy, diversity, and population sizes. Max Weber plans to catch fifteen individual specimens of each of the 500 known deep-sea Gulf fish species to help us better understand these organisms and how the Deepwater Horizon oil Read More
