Description
Summary:Seismic surveys can increase hydrocarbon deposit information, lowering subsequent expected costs of hydrocarbon exploration. Survey noise, however, can interfere with marine mammals and fishes, reducing fitness. Ice-covered Arctic waters temporally constrain both surveying and marine mammal species; damage mitigation requires temporal and spatial planning. The survey noise externality is stronger than that for drilling (Erbe, 2012); there is additional cost to marine species’ habitat versus drilling alone. We develop a spatially explicit bio-economic and Value-of-Information (VOI) model examining these tradeoffs and illustrate it for oil exploration decisions off the Western Greenlandic coast. We use cost-effectiveness to identify implicit thresholds for sound habitat quality conservation as a function of regulatory choices that have different impacts under different assumptions about the relative spatial values of marine mammal habitat maintenance.
