Oceans & Seas

Authors measure nutrient content in coral reef fishes in Seychelles and show that reef fish are important sources of selenium and zinc and contain levels of calcium, iron, and omega-3 fatty acids comparable with other animal-source foods.

Aquatic foods are increasingly being recognized as having an important role to play in an environmentally sustainable and nutritionally sufficient food system. Proposals for increasing aquatic food production often center around species, environments, and ambitious hi-tech solutions that mainly will benefit the 16% of the global population living in high-income countries.

This book chapter advances SDG 14 by explaining the significant change in the exploration, study, and understanding of the oceanography of the Arctic Mediterranean. The first SCISEX cruise with USS Pargo 1993 indicated that the salinity and temperature in the upper layer of the Eurasian Basin were higher than previously reported, while the upper layer salih upward-looking sonars, and when the newly observed thicknesses were compared with those measured 30 years earlier, they indicated that the mean ice thickness had been reduced by about 40%. Suddenly change rather than constancy became the focus, and observations spread over time, which previously had been used to describe the mean circulation and the mean state, now acquired a time dimension.
