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.
How much carbon can the ocean absorb, and what happens to it as the planet warms? Sonya Dyhrman, a microbial oceanographer and professor at Lamont-Doherty Earth Observatory, is trying to answer these questions. (Lamont is ...
