Pennsylvania State University scientists analyzed images of impacted and non-impacted deep sea corals to characterize their symbiotic relationship with brittle stars and determine if brittle stars influenced coral recovery from the Deepwater Horizon spill.

Members from NCEAS, DataONE and Data Carpentry are teaming together to provide an NCEAS led, 3-week open science training event. This training event will be hosted by the National Center for Ecological Analysis (NCEAS), Santa Barbara CA, July 10th – 28th.

Scientists developed a new model to predict how much oil from a spill might bind to sediments or organic matter in the water column. The model, A-DROP, introduces a formula that accounts for oil stabilization by particles, particle hydrophobicity, and oil-particle size ratio.

Scientists from LSU are set to present new research at the 2017 Gulf of Mexico Oil Spill and Ecosystem Science Conference in New Orleans.

Meiofauna are invertebrate organisms that live in seafloor sediments. These marine creatures perform ecosystem functions such as trophic transfer, biogeochemical cycles, pollution removal, and sediment transport stability.

Scientists analyzed weathered and fresh Macondo oil to learn about oil products resulting from microbial degradation and photochemical reactions. They observed that 48 months after the Deepwater Horizon spill, less than 1 percent of oil remained in marsh sediments collected from heavily-impacted sites; however, it was still 400 times greater than sites with moderate-to-no observed oiling.

Opportunity: Environmental Scientist, GS-0401-12/13 (DE/CR), NOAA – JANUARY 28, 2017 GS-13 Level Environmental Scientist sought for the National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Office of Response and Restoration (ORR), in New Orleans, Louisiana. Applications are due Monday 1/30/2017
Details
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.
Details
Marshes depend on a healthy, well-functioning complex of plants, microbes, and benthic communities to support the environmentally and economically important ecosystem services they offer, such as reducing storm surges and providing nursery grounds for many species.

Scientists conducting oil spill research participated in the 2013 Marine Oil Snow Sedimentation and Flocculent Accumulation (MOSSFA) workshop. The researchers discussed the formation and fate of oil-associated marine snow and its ecological impacts on deep-sea environments and made recommendations for future marine oil snow research.
