NOAA Fisheries uses satellite tagging, acoustic monitoring, and machine learning to track humpback whale migration and reduce ship strikes.
A 37-year CalCOFI time series provides direct evidence of ocean acidification in the Pacific — the oldest such record in the ocean.
A species-level inventory of marine bioluminescence documents the phenomenon across all major animal groups — from bacteria to fish.
A Great Barrier Reef study finds fully protected no-take zones support more than 3× the fish biomass of open fishing zones.
A multidecadal hydrographic study estimates the biological carbon pump exports 15 Pg C per year — with the mesopelagic zone playing a critical role.
Loggerhead turtles can learn the magnetic signatures of oceanic locations — the first experimental evidence that animals can learn magnetic map cues.
