4.5 Potential Effects of Oil and Gas Development Theoretical considerations of potential oil and gas development impacts on marine species have been discussed previously for the St. George Basin (Hameedi 1982) and the North Aleutian Shelf (Thorsteinson 1983) in the southeastern Bering Sea. Several workshops held at Asilomar, California (1980) and at Anchorage, Alaska (1981, 1982) considered the impact of oil in this region on commercial crustaceans, notably Tanner crab and red and blue king crab. Largely as a result of these meetings at which biological information on the species was summarized in regards to potential oil impact, shortcomings in available information crucial for oil impact assessment were identified and projects such as the present study were initiated. Consequently, literature dealing with potential hydrocarbon impacts on crab and shrimp of the southeastern Bering Sea has been reviewed several times over recent years (Armstrong, et al. 1981a, 1983a,b; Curl and Manen 1982). These reviews have considered both the physiological/biological sensitivity of crustaceans to hydrocarbons and the ecological vulnerability of selected species. The following discussion is limited to potential impacts of oil spills. A consensus that red king crab along the NAS and blue king crab around the Pribilof Islands are species of high ecological vulnerability (Armstrong, et al. 1983a) prompted OCSEAP to support research that would better portray the general ecology of these species (e.g., distribution and abundance over different substrate types), and establish links between the population dynamics and year class strength of larvae, juveniles and mature females. As noted by Armstrong, et al. (1983b), the relative interannual variability in temporal and spatial population dynamics of larvae should be considered in terms of: 1) female stocks as the origin of hatch; and 2) young benthic juveniles as the final location of pelagic survivors. This theme has been expanded in the current study and serves as a basis for discussing potential oil impacts to red king crab in the NAS-Bristol Bay region. 396
The approach taken in this analysis is one that considers major life history stanzas of the species in regards to important biological and ecological traits, and discusses the modes and extent of oil pollution as it may affect these stages. Use of life history stanzas is considered a sound categorical division for comparing and contrasting physiological, reproductive and ecological changes that occur during a life cycle (Wooster 1983). Armstrong, et al. (1983b) have provided a review of oil impact literature and interpreted their data in light of these life history stanzas. The assertions and hypotheses of Armstrong, et al. (1983b) have been modified in accordance with the field data acquired during the present study. 4.5.1 Oil Transport Models and Impact Scenarios Before relating the biology of red king crab to predictions of oil impact, it is important to first discuss the physical transport of oil both horizontally and/or vertically by currents, winds and biological processes. A brief recount of oil impact scenarios used at OCSEAP synthesis meetings will illustrate the locations and magnitude of oil pollution considered to be representative of possible spills along the NAS and in the St. George Basin. These scenarios will serve as a point of reference in framing estimates of species' vulnerability based on data in this report. Two models of physical transport processes, water movements and biological interactions and responses to oil in the Bering Sea have been constructed (Leendertse and Liu 1981; Sonntag, et al. 1980). Several models of water transport and circulation have been based on net current directions and velocity (Hebard 1959; Kinder and Schumacher 1981b), and on methane profiles (Cline, et al. 1981). Hebard (1959) described currents moving to the northwest through Unimak Pass, with a component then moving northeast along the North Aleutian Shelf. Although the direction of the current is highly variable and 397
