Using MODIS and MERIS to detect seeps

In search of oil seeps in the Cariaco basin using MODIS and MERIS medium resolution data

The Cariaco basin with its high sedimentation rates and active faulting make it a favorable place for active oil seeps to occur. Information on the number of seeps or their locations does not exist in the literature. Data collected from the MODIS and MERIS sensors were examined to see if they could detect oils seeps in the Cariaco basin. MODIS was able to detect 2 regions of surface slicks in 2011, however, identifying where they came from is more complicated. By identifying multiple slicks from the same region, Chen and Hu determiend that they can be traced to the same location. These sensors can be used to conservatively estimate the number of slicks as long as they are at least 3 pixels in length on the image.

Podcasts from The Loop

The Loop is a series of podcasts which take an in depth look at C-IMAGE research. Partnering with Mind Open Media reporters Ari Daniel Shapiro and David Levin, our researchers share the importance of their studies and how they help our understanding of oil spills. David and Ari have produced eight podcasts and have more in the queue. The podcasts are linked below. Plug in and learn about our research!
