Abstract

Abstract. Campeche Bay, located in the Gulf of Mexico, is a well-established fossil fuel producing region, with numerous oil rigs exploring oil and natural gas. In an effort to reduce negative impacts on marine ecosystems, Pemex continuously monitored Campeche Bay for oil slicks, i.e., naturally occurring oil seeps and manmade oil spills. A long-term dataset (2000–2012) of synthetic aperture radar measurements from both RADARSAT satellites (766) is leveraged to investigate the spatial-temporal distribution of oil slicks (14,210) in this region. The present study has a threefold goal: (1) describe the monitoring strategy completed by Pemex and the information produced during such monitoring; (2) investigate the spatial-temporal distribution of the oil slicks observed in Campeche Bay, centering on aspects related to their occurrence; and (3) demonstrate the usefulness of RADARSAT-derived information in the execution of effective long-term environmental applications to locate seeps and spills on the sea surface. The observations confirm the massive oil input contribution of the Cantarell Oil Seep to the Campeche Bay. Oil spills (96%) usually occur in water depths shallower than 100 m, whereas oil seeps (63%) commonly occur in waters deeper than 1,000 m. The successful long-term application of RADARSAT-derived information has been shown.

Résumé. La Baie de Campeche, située sur la côte Mexicaine dans le Golfe du Mexique, est une région productrice de combustibles fossiles, avec de nombreuses plateformes exploitant le pétrole et le gaz naturel. Afin de réduire ses impacts négatifs sur les écosystèmes marins, Pemex surveille en permanence la Baie de Campeche pour les fuites naturelles et anthropiques. Les données pluriannuelles (2000–2012) des mesures de radar à synthèse d’ouverture «synthetic aperture radar» des satellites RADARSAT (766) sont utilisées pour étudier la distribution spatio-temporelle des nappes de pétrole (14.210) dans cette région. La présente étude a un triple objectif: (1) décrire la stratégie de surveillance de Pemex et les informations qu’elle a produites; (2) etudier la distribution spatio-temporelle de la nappe de pétrole de la Baie de Campeche, notamment les aspects liés à son occurrence; et (3) démontrer l’utilité des informations obtenues par RADARSAT dans les systèmes à long terme de surveillance environnementale en milieu marin. Les observations confirment l’énorme impact du suintement d’huile Cantarell dans la Baie de Campeche. Généralement, les déversements de pétrole (96%) surviennent à moins de 100 m et les suintements (63%) à plus de 1,000 m de profondeur. L’efficacité de l’utilisation à long terme de RADARSAT a été démontrée.
