Study Develops Biogeographic Classification of the World’s Deep Oceans

An interdisciplinary panel of 23 experts in oceanography, ecology, physics, and geospatial-mapping combined their knowledge of pelagic faunal distribution patterns to create a biogeographic map of the world’s deep oceans. The panel identified 33 distinct mesopelagic (200-1000 meters depth) ecoregions that reflect regional variation of biodiversity and function.

Science at Sea: Researchers Monitor Marine Ecosystems Near Deepwater Horizon

A 12-day science expedition on the exploration vessel Ocean Intervention II embarks June 11 to investigate how oil, gas, and chemical dispersants affect marine life and their environment deep in the Gulf of Mexico. Scientists and outreach personnel onboard the vessel will interact with the public and school-age children using streaming video, social media, and question-and-answer sessions.
