It is also the first spill in which the incorporation of oil and/or dispersant into marine snow was directly observable. Marine snow formation, incorporation of oil (MOS – marine oil snow) and subsequent settling to the seafloor, has been termed MOSSFA: Marine Oil Snow Sedimentation and Flocculent Accumulation. This pathway accounts for a significant fraction of the total oil returning back to the sea floor. GOMRI funded studies have determined that important drivers of MOSSFA include, but are not limited to, an elevated and extended Mississippi River discharge, which enhanced phytoplankton production and suspended particle concentrations, zooplankton grazing, and enhanced mucus formation (operationally defined as EPS, TEP, marine snow). Efforts thus far to understand the mechanisms driving these processes are being used to aid in the development of response strategies. These include modeling efforts towards predicting plume dynamics. Although much has been learned during the GOMRI program (reviewed herein and elsewhere), there are still important unknowns that need to be addressed. Understanding of the conditions under which significant MOSSFA events occur, the consequences to the biology, the sinking velocity and distribution of the MOSSFA as well as its ultimate fate are amongst the most important consideration for future studies. Also important is the modification of the oil and dispersant within the MOS and its transport as part of MOSSFA. Ongoing studies are needed to further develop our understanding of these complex and interrelated phenomena.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88480565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system consists on a UAS that carries multiple cameras that integrate 10 wavelength band sensors ranging from Ultra-Violet (UV) to Long Wave Infrared (LW-IR). This system has been originally tested at OHMSETT and at the MC-20 site in the Gulf of Mexico. More recently this UAS was put in operation during the Lake Washington Wellhead blowout in Louisiana. In here we present examples of how this operational tool allowed oil spill responders to efficiently deploy containments of the floating oil (booming) and to monitor the collection of the oil on real time. Moreover, using a rapid classification algorithm, the multispectral data collected by our UAS allowed us to make a detailed high resolution classification of the oil detected on the shorelines of the affected areas. The UAS also delivered near real time oil detections that were used during the spill by the NOAA oil spill science coordinators through the ERMA system. This UAS has proven its ability to detect oil on ‘hard to reach areas’ and it offers a valuable option for the evaluation of affected areas impacted by the spill. We compared the SCAT surveys with the UAS oil detections and conclude the importance of adding this UAS tool as part of the operational assessment of the spill to determine the level of impact of the spill on the nearshore environment.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90092575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An SRP builds on the recognized strengths of an IMS-based organization and of a SCAT program that utilizes an integrated and focused approach to streamline and better coordinate the decision and planning processes and the operational implementation activities. An SRP is an extension of the traditional SCAT program but with a broader focuses on strategic and tactical planning to minimize the short- and long-term impacts of oil on shorelines, the efforts and costs involved in a shoreline response, and the volumes of waste that would be generated. The inclusion of an SRP concept in drills, exercises and preparedness training can directly improve the ability to respond quickly and effectively during the initial response phase. Not implementing an SRP at the very outset of a spill response, when typically the best opportunities exist for the removal of bulk oil, can have significant long-term consequences. Shifting an emphasis on management and physical resources from, often only partially successful, on-water activities to onshore shoreline activities when oil can be picked up more rapidly and effectively can significantly reduce i) the footprint of the response, ii) the duration and scale of the shoreline operation, iii) the exposure of shore zone resources to the oil, and so accelerate environmental recovery, and iv) waste generation.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81233458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The regulations have been in effect since 1983 requiring oceangoing vessels of less than 400 gross tons to have the capacity to retain all oily mixtures onboard or install an approved oily water separator (OWS) equipment for processing oily mixtures from bilges.\u0000 New Bedford, MA is the homeport to over 400 commercial fishing vessels within a 2 square mile port area. The circumstances in New Bedford are considered to be representative of most ports for vessels less than 400 gross tons nationwide. Sector SENE has used various mechanisms to educate the local commercial vessel fleet owners and operators. The education includes the issuance of Marine Safety Information Bulletin 03-18 by Coast Guard Headquarters (United States Coast Guard, 2018).\u0000 In 2012, the Partner Agency - Massachusetts Department of Environmental Protection created and funded the Bilge-Pump-Out Program. This voluntary program provides commercial vessels with free oily bilge waste disposal services. Previously, there was no established “permanent” solution to the pervasive oily discharge problem and bad practice of illegally disposing of oily waste directly from commercial vessel bilges overboard into U.S. navigable waterways. In conjunction with local authorities having jurisdiction, Sector SENE began a focused pollution prevention and enforcement effort. Several pollution cases were forwarded to the Department of Justice (DOJ) and fines of over 1 million dollars have been issued for the illegal practices. The culmination of educational outreach, surge operations and coordinated interagency efforts have led to the initial levels of compliance.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77827818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper will discuss these activities. Immediately following the incident, the U.S. oil and natural gas industry launched a comprehensive review of offshore safety and operations to identify potential improvements in spill prevention, intervention, and response capabilities. Four joint industry task forces were assembled to focus on the critical areas of equipment, operating procedures, subsea well control and oil spill response. In addition to their own work, the task forces fully considered the recommendations of the Presidential Oil Spill Commission in forming their recommendations to improve offshore safety and response in the respective four areas. One of the major recommendations and actions directly linked to the Presidential Commission recommendations was the formation of an industry organization fully focused on Safety and Environmental Management Systems (SEMS) and managing risk. The industry organization formed is the Center for Offshore Safety (COS). The COS is fully focused on SEMS and its continual improvement through SEMS Auditing, safety data collection and analysis, good practice development, and sharing industry information. Additionally, there has been a continuing special focus on new and enhanced Industry standards. The task force on equipment and other post-Horizon reports contained strong recommendations on the need to develop new and revised standards to enhance safety in the offshore. This work was done through the standards development process and organizations including collaboration with national and international Standards Development Organizations, the offshore oil and gas community, and the Federal government.

To protect the health of SMART teams, boats typically remain at least 2 miles away from slicks during aerial dispersant treatment. After the spray completes, the SMART boats transit into oil slicks. The time between completion of spray and initiation of SMART monitoring can be > 30 minutes. In 30 minutes, dispersed oil plumes will significantly dilute making them difficult to detect based on fluorescence. Further, we identified a separate issue. That is, oil fluoresces primarily because of the aromatic constituents in the oil and many of the aromatics in oil are at least somewhat volatile and water soluble. Modeling found that these aromatics leach from the oil prior to the application of dispersant. So, even if fluorometers were immediately underneath dispersing oils slicks, the loss of aromatics from the oil challenges SMART. The combination of aromatic leaching and rapid plume dilution limits the ability of the Tier II/III SMART protocol to identify fluorescence signals above the recommended five times background. This means that effectively dispersed oil slicks might not be accurately characterized. What is needed is a monitoring technique that can be applied rapidly and targets some other characteristic of the oil.\u0000 Polarized infrared (IR) cameras can measure both the thermal differences between slicks and water and the difference in emissivity when IR energy is emitted by sheens / slicks relative to water. These cameras can be easily flown on dispersant spray/support planes. They can be used to image oil slicks before, during, and after dispersant spray operations. Effectively dispersed oil slicks will have a significant change in their thermal signature and IR emissivity as the oil transfers from the water surface into the water column. Polarized infrared cameras can be an effective tool for monitoring dispersant operations. They can be deployed continually during slick dispersion providing a longitudinal and synoptic record of the dispersion process.\u0000 In this paper, we describe modeling to estimate the water-column concentrations of aromatic hydrocarbons (both mono and polycyclic) from plumes after applying dispersants to an oil slick. In addition, we describe testing of a polarized IR camera at the OHMSETT tank during dispersant testing. We use the modeling to identify the need for modifying SMART and the OHMSETT testing to show that polarized IR cameras can meet this need.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84633870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physical processes are strongly influenced by the interaction of circulation in the GoM deep basin interior and in the surrounding shelf areas of diverse morphologies that include deltas, estuaries, barrier islands and marshes. This was particularly evident during the 2010 Deepwater Horizon (DwH) incident, a deep blow-out close to the Northern GoM shelves, over an area strongly affected by the brackish river plume originated from the Mississippi River Delta. The specific physical conditions are revisited, to illustrate the synergy between the evolution of the Loop Current – Florida Current system and the rapidly changing shelf and coastal currents under the influence of river runoff and winds. Each of these physical factors had been studied prior to the DwH incident, but their combined effects on hydrocarbon pathways were not known.\u0000 Examples are given on what has been learned through research under the Gulf of Mexico Research Initiative (GoMRI) in the last 10 years. The focus is on transport processes in the GoM along the ocean continuum from the deep basin interior to the coastal and wetland areas, and their relevance for oil transport and fate. Post-DwH studies have advanced regarding methodologies and tools. These include multi-platform observations and data analyses, in tandem with high-resolution, data assimilative models for past simulations and predictions.\u0000 Important new findings include the connectivity between remote coastal regions, as deep oceanic currents can facilitate the cross-marginal transport of materials not only locally, but regionally. This creates a broader and more challenging view for the management of coastal marine resources that should be integrated for preparedness and response. Two examples are presented on connectivity processes. First, advances in the understanding of transport rates and pathways from the Mississippi Delta to the Florida Keys. Second, new findings on how coastal circulation near Cuba influences the evolution of the Loop Current system and the oil fate from a potential oil spill in Cuban waters.\u0000 The synthesis of the above findings aims to demonstrate how knowledge acquired during GoMRI can advise future planning of scientific research to aid preparedness and response not only for the GoM, but for many offshore areas of oil exploration. The goal is to advance the understanding and predictability of oil slick trajectories over pathways from the deep to the coastal environment and vice versa.","PeriodicalId":14447,"journal":{"name":"International Oil Spill Conference Proceedings","volume":"311 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72761679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
