The study was contracted for the purpose of investigating the sensitivity of Arctic krill, namely the euphauslid Thysanoessa raschii, to the water soluble fraction (WSF) of Prudhoe Bay crude oil. The study had two primary objectives: (1) determine, through laboratory bioassays, the 96-hr LC50 of Prudhoe Bay crude oil WSF for T. raschii; and (2) estimate the losses to populations of T. raschii and the potential recovery rates resulting from hypothetical oil spills in the Beaufort Sea. The major concern prompting the study is the fact that euphauslids are a major food source for the endangered bowhead whale in the western Beaufort Sea.
