Increasing nitrogen loading in the Gulf of Mexico undermines coral reef resilience

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 some of the healthiest in the continental United States, but recent disease outbre...

Reduced N2 fixation in the tropical Atlantic Ocean during the warm late Pliocene
