The ongoing global decline of coral reefs underscores the need to identify key mechanisms driving reef deterioration. The Flower Garden Banks (FGB) reefs in the northern Gulf are widely regarded as so...

A belt of seaweed has formed across the tropical Atlantic nearly every year since 2011, despite reduction in its extent elsewhere. The causes of this growth are now coming into clearer focus.

Arctic sea-ice loss affects biological productivity, sustenance in coastal communities, and geopolitics. Forecasting these impacts requires mechanistic understanding of how Arctic sea ice responds to ...

High near-surface nitrogen-fixation rates that promoted the recent growth of the Great Atlantic Sargassum Belt were tied to greater upwelling of phosphorus from the equatorial Atlantic, according to c...

Basin-wide depth profiles of nitrate δ15N and δ18O indicate a supply of low-δ15N N to the Mediterranean Sea Nitrate δ15N can be explained by modest rates of N2 fixation and/or anthropogenic N dep...

Incorporation of animal-based foods into early hominin diets has been hypothesized to be a major catalyst of many important evolutionary events, including brain expansion. However, direct evidence of ...

Elevated sea surface temperatures are causing an increase in coral bleaching events worldwide, and represent an existential threat to coral reefs. Ear…

The impact of global warming on the ocean’s oxygen-deficient zones (ODZs) is uncertain, partly because of a lack of data on past changes. We report monthly resolved records of coral skeleton–bound nit...

Nitrogen isotope evidence of Mid-Devonian photosymbiotic associations in certain types of corals suggests that autotrophic and heterotrophic corals co-existed on extinct reefs, as today, but in w...
