What is VIIRS?
The visible infrared imaging radiometer suite, or VIIRS, is a satellite-based highly sensitive optical sensor to see lights at day and night. The sensor is highly sensitive so that it can detect light emitted by vessels on the ocean at night. The Earth Observation Group (EOG) at the Colorado School of Mines has developed an […]

Rendezvous at Sea: What is Transshipping?
In the commercial fishing world, transshipment is the transfer of catch from one vessel to another. During a transshipment, a fishing vessel meets up with a large refrigerated cargo-type ship, known as a “reefer.” They tie up alongside one another and drift while the fishing vessel offloads tons of catch before heading back out to […]
