Proposed developments of oil and gas in Canada's Arctic may impact severely on shorelines, wildlife and habitats, and native land uses in the coastal zone. The large scale of these projects requires prior comprehensive planning and environmental assessment at regional scales. Along with other social and environmental information, data on shore types is required. This paper describes a Canadian program of Arctic marine shore classification at regional scales. To date, 20 classes of landform association are used to map, at 1:250,000, shore types for about one-third of the Arctic islands. Applications can include the rating of sensitivity to oil spills, logistics planning for monitoring and emergency measures, site selection and habitat assessment, etc. Examples of shore classes and evaluations are given.

Abstract 2017-161 Over the past four decades, the oil and gas industry has made significant advances in being able to detect, contain and clean up spills and mitigate the residual consequences in Arctic environments. Many of these advances were achieved through collaborative research programs involving industry, academic and government partners. The Arctic Oil Spill Response Technology - Joint Industry Programme (JIP), was launched in 2012 and completed in early 2017 with the objectives of building on an already extensive knowledge base to further improve Arctic spill response capabilities and better understand the environmental issues involved in selecting and implementing the most effective response strategies. The JIP was a collaboration of nine oil and gas companies (BP, Chevron, ConocoPhillips, Eni, ExxonMobil, North Caspian Operating Company, Shell, Statoil, and Total) and focused on six key areas of oil spill response: dispersants; environmental effects; trajectory modeling; remote sensing; mechanical recovery and in-situ burning. The JIP provided a vehicle for sharing knowledge among the participants and international research institutions and disseminating information to regulators, the public and stakeholders. The network of engaged scientists and government agencies increased opportunities to develop and test oil spill response technologies while raising awareness of industry efforts to advance the existing capabilities in Arctic oil spill response. The JIP consisted of two phases, the first included technical assessments and state of knowledge reviews resulting in a library of sixteen documents available on the JIP website. The majority of the JIP efforts focused on Phase 2, actual experiments, and included laboratory, small and medium scale tank tests, and field research experiments. Three large-scale field tests were conducted in the winter and spring months of 2014–2016 including recent participation of the JIP in the 2016 NOFO oil on water exercise off Norway. The JIP was the largest pan-industry programme dedicated to oil spill response in the Arctic, ever carried out. Twenty seven research projects were successfully and safely conducted by the world’s foremost experts on oil spill response from across industry, academia, and independent scientific institutions in ten countries. The overarching goal of the research was to address the differing aspects involved in oil spill response, including the methods used, and their applicability to the Arctic’s unique conditions. All research projects were conducted using established protocols and proven scientific technologies, some of which were especially adjusted for ice conditions. This paper describes the scope of the research conducted, results, and key findings. The JIP is committed to full transparency in disseminating the results through peer reviewed journal articles, and all JIP research reports are available free of charge at www.arcticresponsetechnology.org.

With recent increased interest in oil and gas exploration and development in the Arctic comes increased potential for an accidental hydrocarbon release into the cryosphere, including within and at the base of snow. There is a critical need to develop effective and reliable methods for detecting such spills. Numerical modeling shows that ground-penetrating radar (GPR) is sensitive to the presence of oil in the snow pack over a broad range of snow densities and oil types. Oil spills from the surface drain through the snow by the mechanisms of unsaturated flow and form geometrically complex distributions that are controlled by snow stratigraphy. These complex distributions generate an irregular pattern of radar reflections that can be differentiated from natural snow stratigraphy, but in many cases, interpretation will not be straightforward. Oil located at the base of the snow tends to reduce the impedance contrast with the underlying ice or soil substrate resulting in anomalously low-amplitude radar reflections. Results of a controlled field experiment using a helicopter-borne, [Formula: see text] GPR system showed that a [Formula: see text]-thick oil film trapped between snow and sea ice was detected based on a 51% decrease in reflection strength. This is the first reported test of GPR for the problem of oil detection in and under snow. Results indicate that GPR has the potential to become a robust tool that can substantially improve oil spill characterization and remediation.

Climate change has removed large quantities of ice and has removed impediments to Arctic sea navigation and in doing so has opened up a new route. Most of these ice-free routes can be used for navigation including oil and gas logistics and transportation and reducing transit by more than 5000 nautical miles. While these events allow for a widening of transportation routes but many challenges naturally inherent to the Arctic are still present, for example, the risk of possible oil spills in the very sensitive ecosystem and the safety risks to crew and equipment. New Technology offers more thorough ways to minimize and manage this risk and to preserve the integrity of ecosystems, safety of people and the profits of companies where operations are more cost sensitive and difficult than in other regions of the world. This paper proposes one model of risk reduction and evaluates the best ways to reduce ecological and safety risks of oil and gas companies operating in the Arctic route. It also proposes methods to incorporate digital value into the organization through four sectors, Sustainability, Efficiency, Accountability and Profitability.

Abstract. Characterizing methane sources in the Arctic remains challenging due to the remoteness, heterogeneity and variety of such emissions. In situ campaigns provide valuable datasets to reduce these uncertainties. Here we analyse data from the summer 2014 SWERUS-C3 campaign in the eastern Arctic Ocean, off the shore of Siberia and Alaska. Total concentrations of methane, as well as relative concentrations of 12CH4 and 13CH4, were measured continuously during this campaign for 35 d in July and August. Using a chemistry-transport model, we link observed concentrations and isotopic ratios to regional emissions and hemispheric transport structures. A simple inversion system helped constrain source signatures from wetlands in Siberia and Alaska, and oceanic sources, as well as the isotopic composition of lower-stratosphere air masses. The variation in the signature of lower-stratosphere air masses, due to strongly fractionating chemical reactions in the stratosphere, was suggested to explain a large share of the observed variability in isotopic ratios. These results point towards necessary efforts to better simulate large-scale transport and chemistry patterns to make relevant use of isotopic data in remote areas. It is also found that constant and homogeneous source signatures for each type of emission in a given region (mostly wetlands and oil and gas industry in our case at high latitudes) are not compatible with the strong synoptic isotopic signal observed in the Arctic. A regional gradient in source signatures is highlighted between Siberian and Alaskan wetlands, the latter having lighter signatures (more depleted in 13C). Finally, our results suggest that marine emissions of methane from Arctic continental-shelf sources are dominated by thermogenic-origin methane, with a secondary biogenic source as well.

ABSTRACT The increase in petroleum development activities in the arctic region has raised concerns over potential oil spills during the broken ice season. Currently, exploratory drilling for oil and gas is restricted during this season due to the lack of proven oil spill cleanup methods for broken ice fields. Test programs have been conducted at the U.S. Environmental Protection Agency's Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT) to determine the feasibility of cold weather testing and to evaluate various oil spill cleanup methods considered for use in the arctic. This paper describes a test program to determine the practicality of using a catamaran-mounted rope-mop skimmer for spill cleanup in broken ice fields. An Oil Map Pollution Control, Ltd., prototype arctic skimmer was tested in the test tank under controlled conditions during January 30 to February 7, 1984. Freshwater ice cubes of 250 to 280 millimeters (mm) were used in the tests to approximate a broken ice field. During tests, a predetermined ice condition was established across the encounter width of the rope mops and oil was distributed over the ice. The oil and ice were channeled into the skimmer by two booms, which were joined to the skimmer at the bow. Nine tests were conducted at a tow speed of 1 knot using Circo 4X light oil. During the tests, ice concentrations were varied from 0 to 75 percent of the surface area, and oil slick thickness varied from 3 to 8 mm. The test results demonstrated the spill cleanup capability of the skimmer in ice-infested waters having up to 50 percent ice coverage. At higher ice concentrations, the skimmer was ineffective due to ice jamming at the skimmer inlet.

AbstractDiscovery of petroleum resources in Arctic waters and the rapid loss of sea ice raise concerns over environmental risks of oil development in Arctic waters. One of the biggest threats to the marine environment from offshore oil production is a large-scale oil spill, akin to Deepwater Horizon. The challenging operating conditions, lack of infrastructure and effective clean-up techniques in the Arctic conditions exacerbate the need to ensure robust regulation of petroleum activities in the region. Whereas national laws vary extensively across the Arctic States, international law does not offer a uniform approach to prevention of and response to oil spills. This paper examines the scope and application of the relevant treaties and argues that a regulatory gap exists in the prevention of oil spills and addressing the challenges of response in Arctic conditions. It further suggests that there is an increasing role for soft-law regional cooperation in addressing these gaps.
