New research looks at how different species have managed to cross geographic barriers throughout history and whether their individual traits played a crucial role in these journeys.

Understanding how both cloud cover and temperature work to promote coral bleaching provides valuable insight into how reefs will change over various climate scenarios.
A climate overshoot that creates warmer oceans with lower oxygen levels will reduce the suitable habitat for many marine species long after CO₂ levels have peaked and declined.
Scientists collect water and sediment samples to study how the oceans and climate are changing.

As oceans warm, Canada’s marine protections system looks woefully inadequate. New monitoring systems and flexible governance can help Canada protect the areas most likely to have the greatest impact.

Exploring the often unseen, and poorly understood, nuances of diversity within coral reefs may prove essential for ensuring the long-term health of Earth’s oceans.
Ocean temperatures have hit record highs off the Florida Keys. Scientists and volunteer divers are racing to save these valuable creatures.
Is the sun setting on the Atlantic ocean current system? While not impossible, it is certainly not imminent, and overly sensationalist headlines do little to further the cause of tackling the climate crisis.

Recent headlines around the supposed impending collapse of the Atlantic currents remind us of the importance of avoiding sensationalism in facing global warming.

Rip currents are a leading cause of near-shore drownings, but there are effective ways to survive one. And these phenomena also play important ecological roles that are an emerging research area.

Water temperatures in the 90s off Florida in July are alarming, a NOAA coral scientist writes. Scientists in several North American countries have already spotted coral bleaching off their coasts.
Sharks and rays are rapidly declining globally, and their situation is representative of many other exploited marine species that lack scientific monitoring.
