AbstractIn order to assess the potential impact from oil spills and decide the optimal response actions, prediction of population level effects of key resources is crucial. These assessments are usually based on acute toxicity data combined with precautionary assumptions because chronic data are often lacking. To better understand the consequences of applying precautionary approaches, two approaches for assessing population level effects on the Arctic keystone species polar cod (Boreogadus saida) were compared: a precautionary approach, where all exposed individuals die when exposed above a defined threshold concentration, and a refined (full-dose-response) approach. A matrix model was used to assess the population recovery duration of scenarios with various but constant exposure concentrations, durations and temperatures. The difference between the two approaches was largest for exposures with relatively low concentrations and short durations. Here, the recovery duration for the refined approach was less than eight times that found for the precautionary approach. Quantifying these differences helps to understand the consequences of precautionary assumptions applied to environmental risk assessment used in oil spill response decision making and it can feed into the discussion about the need for more chronic toxicity testing. An elasticity analysis of our model identified embryo and larval survival as crucial processes in the life cycle of polar cod and the impact assessment of oil spills on its population.

Combatting oil spills in the Arctic is a major challenge. Drilling or producing oil or gas in the marginal ice zone (MIZ) may allow booms to be deployed upstream of an offshore structure to clear the water of ice, thereby enabling conventional oil spill countermeasures to be used. Such a boom would be kept in place by two ice-going service vessels or by moored buoys. SINTEF NHL and NRC have performed a number of small-scale tests with a flexible boom in the NRC ice basin in Ottawa. The purpose of the tests was to measure the effectiveness of using a flexible boom for collecting ice, and to determine the loads associated with collecting the ice. In the tests, various boom configurations were towed against a broken ice field consisting of ice pieces typically 50–100 mm across and 30 mm thick. The ice concentration was usually 10/10, but it was reduced to 8/10 and 5/10 for two tests. The boom was towed at speeds of 20 and 50 mm-s−1. Both the width of the boom and the slackness of the boom were varied over reasonable ranges. Two six-component dynamometers were used to support the boom. Thus, the force components on each end of the boom were measured. Further, two video cameras were used to record the effectiveness of each boom configuration. In this paper, the full results of this test program are presented and the application of the test results to the full-scale situation are discussed. The tests show that, under certain conditions, the use of boom is feasible for ice management in oil-contaminated water.

ABSTRACT Environment Canada has established standard operating procedures (SOPs) for their emergency response officers so that they can respond to environmental emergencies with a uniform and professional approach. The SOPs cover a wide range of issues due to the complexity and intricacy of spills and related emergency situations. The focus here is on procedures for responding to oil spills. These include, but are not limited to, conducting a preliminary assessment of the spill, determining lead government agency responsibility, assessing and addressing response and protection needs, ensuring appropriate information is documented and distributed to concerned groups, dealing with the media, obtaining legal evidence and support, arranging finances, and using and obtaining approval for implementing certain response technologies.

ABSTRACT The Center for Fire Research (CFR) at the National Institute of Standards and Technology (NIST) is conducting research related to safety in offshore drilling and oil spill pollution under joint funding from Minerals Management Service (MMS), U.S. Coast Guard, and the American Petroleum Institute. Technical assistance in measurement has been donated by Environment Canada. This research has focused on examining the phenomena associated with crude oil combustion and the impact of using burning as a spill response method. The process of burning crude oil on water as a means to mitigate oil spills has been investigated with a research effort combining both small-scale experiments and calculations. As a result of these studies, there has been increased understanding of the burning process, including burning rate, heat radiation, smoke emission, smoke composition, and smoke dispersion in the atmosphere. A key to gaining acceptance of burning as a spill response technique is the demonstration that favorable results obtained at laboratory scale can be shown to continue in test burns representing the size of fires expected in actual operations. Field-scale burn tests are being planned and coordinated jointly by MMS, API, USCG, and Environment Canada to document the use of burning technology under conditions simulating actual oil spill cleanup operations. The purpose of this project is to measure the effects of oil spill burning in laboratory and field tests.
