Oiled wildlife response for Antarctica: Practical and realistic solutions

Abstract

ABSTRACT Through the Antarctic Treaty on Environmental Protection all of the Antarctic member nations are required to have in place contingency plans for oil spills including oiled wildlife response. The current risks for marine pollution incidents to the Antarctic environment include refuelling activities associated with Antarctic stations/bases; routine station/base activities; and shipping associated with stations/bases, tourism, commercial fishing and whaling. Between 1981 and 2011 there have been reported 33 spills or near spill incidents associated with the Antarctic marine environment. Wildlife at risk from oil spills include seabirds (flying birds and penguins), pinnipeds and cetaceans. Antarctic and polar environments both provide a number of logistical and practical complications given their climatic and geographic character. The key elements for response actions for Antarctic wildlife identified are divided amongst primary, secondary and tertiary oiled wildlife response activities. Primary activities identified include focussing containment and clean up efforts to protecting wildlife as a priority using tools such as sensitivity mapping, stochastic and real time modelling. Secondary activities specific to individual wildlife groups were identified and included specialised hazing, exclusion and pre-emptive capture mechanisms focussed to the Antarctic environment. Tertiary activities are considered with regards to the real capacity of Antarctic stations to respond, take and rehabilitate oiled wildlife given the Antarctic environment and its limitations. The paper identifies realistic mechanisms and systems considering the climatic, logistical and practical issues of the Antarctic environment. Although specific to Antarctic bases the paper outcomes can be equally applied to other polar environments.
