Ocean ecosystems have responded and will continue to respond to climate changes of
different rates, magnitudes, and durations (virtually certain). Human societies depend on …

Abstract In 2018, the Mexican Caribbean coast received a massive influx of pelagic
Sargassum spp. that accumulated and decayed on beaches producing organic …

Water masses can become undersaturated with oxygen when natural processes alone or in
combination with anthropogenic processes produce enough organic carbon that is …

Hypoxia is a mounting problem affecting the world's coastal waters, with severe
consequences for marine life, including death and catastrophic changes. Hypoxia is forecast …

Ocean warming and increased stratification of the upper ocean caused by global climate
