The Space Review – The oceans are integral to our global ecosystem. As a source of nutrition and livelihood for much of the world’s population, ocean health is critical for UN development goals. Activities that jeopardize the sustainability of marine resources, particularly illegal, unreported, and unregulated (IUU) fishing, are therefore a major international issue. Fortunately, space capabilities such as satellite radar and multispectral imaging are making it easier for the international community to track, characterize, and combat illegal fishing.
