Sustainable use of marine resources requires effective monitoring and management of the world’s fish stocks. Remote sensing techniques are being used to help manage fisheries at sustainable levels, while also guiding fishing fleets to locate fish schools more efficiently. Fish tend to aggregate in ocean areas that exhibit conditions favored by specific fish species. Some of the relevant oceanographic conditions, such as sea surface temperature, ocean color (productivity) and oceanic fronts, which strongly influence natural fluctuations of fish stocks, can be observed and measured by remote sensors on satellites and aircraft. The remotely sensed data are provided in near-real time to help fishermen save fuel and ship time during their search for fish; to modelers who produce fisheries forecasts; and to scientists who help develop strategies for sustainable fisheries management. This article describes how acoustic, optical and radar sensors on ships, satellites and aircraft are used with forecast models to improve the management and harvesting of fisheries resources.

Coastal agencies require advance information on the predicted path, intensity and progress of a storm and associated waves and storm surges, near-real-time information during the peak of the storm to monitor flooding and control rescue operations, and post-storm reports to assess the damage and plan and implement the recovery. The same holds true for other disasters, such as oil spills and algal blooms. Coastal communities are also facing a rising sea level, caused mainly by global warming. Airborne and satellite remote sensors, such as multispectral imagers, Lidar and radar, are now able to provide most of the information required for emergency response and coastal management.
