Résumé(Sommaire disponible en anglais seulement)
A series of dark targets derived from a visual interpretation of RADARSAT-1 data from Davis Strait (and part of Baffin Bay) is provided as a baseline for supporting further targeted investigations and as an aid in understanding the subsurface geology and hydrocarbon potential of these basins. While recognizing that many of the 69 SAR features may have origins other than from oil slicks, the identification of these features, false positives included, greatly reduces the area meriting further investigation from the overall 350,000 km2 region surveyed. Persistent detection of dark features through repeat observations is required to more confidently ascribe the origin of these features to natural hydrocarbon seeps.
The longevity of the Scott Inlet seep is demonstrated and suggests the presence of an actively discharging petroleum system. Estimates of the rate and volumes of hydrocarbon from this natural seepage are significant and contribute towards our understanding of the background levels of oil being discharged naturally into the environment of the region. Recognition of seep activity in the region and the potential discovery of new occurrences provide valuable, unconventional geoscience information about the offshore petroleum potential in these eastern arctic basins.
