Marine biology is the scientific discipline that investigates the biology of organisms inhabiting marine and brackish environments, encompassing molecular to ecosystem scales. It examines physiological, genetic, and behavioral adaptations to saline conditions, pressure, light regimes, and hydrodynamics, as well as population dynamics, trophic interactions, and biogeochemical roles of marine taxa from microbes to megafauna. Marine biologists employ field surveys, experimental manipulations, remote sensing, and omics-based approaches to quantify biodiversity patterns, primary production, nutrient cycling, and responses to natural and anthropogenic stressors, thereby informing ecosystem modeling, conservation strategies, and management of living marine resources.
Endangered basking sharks aren't fasting during long-distance migrations. A new study led by the Woods Hole Oceanographic Institution shows that they may be foraging along the way, and in much deeper areas of the ocean than ...
