Understanding the temporal dynamics and spatial distribution of natural seepage phenomena in the Gulf of Mexico is fundamental for the definition of proper environmental management practices in this often cloud-covered region. RADARSAT-1 images analyzed in this paper were acquired using the wide 1 and wide 2 (W1, W2) and ScanSAR narrow 1 (SCN1) beam modes. Image processing was carried out using the unsupervised semivariogram textural classifier (USTC). In combination with RADARSAT-1 satellite images, and essential ancillary data, this technology enhances the detection of seepage slicks on the ocean surface based on radar texture. USTC classification of RADARSAT-1 data provided systematic evidence from space of the presence of prolific, present-day petroleum generation and migration in the Cantarell Complex of oil fields. |
