Seismic surveys can improve estimates of net private benefits from uncertain hydrocarbon deposits. The Value-of-Information (VOI) can capture these gains. At the same time, seismic surveys impose uncertain damages from noise pollution on marine life. Arctic waters are increasingly attractive exploration locales, but ice cover temporally constrains both surveying and marine mammal species. Thus, damage mitigation requires both temporal and spatial planning. We develop a spatially explicit bio-economic model through which we can calculate the VOI from seismic surveying options alongside potential marine mammal displacements. We demonstrate the model using hydrocarbon exploration opportunities off the Western Greenlandic coast. Lacking estimates for marine mammal sound habitat conservation benefits, we use cost-effectiveness (CEA) as an alternative to weakly informed cost–benefit analysis to identify implicit thresholds as a function of regulatory choices based on different relative spatial values of marine mammal habitat conservation. We check robustness using Monte Carlo (MC) simulations. We illustrate how the combined use of VOI, CEA and MC can ease decision making when uncertainties are compounded and cost–benefit analysis is not feasible.
