Researchers are finding alarming concentrations of persistent pollutants such as PFAS in Australian dolphins. These record-breaking levels are cause for concern.
The majestic St. Lawrence River, a jewel of economic, historical and environmental importance, reminds us of the need to preserve this essential ecosystem.
The waters of the St. Lawrence are running out of breath and bottom-dwelling organisms are already feeling the effects. Here’s how ecosystems are reacting.

A recent study focusing on how offshore wind farms in Massachusetts waters could affect endangered right whales does not call for slowing the projects, but says monitoring will be critical.
Growing awareness of sexual harassment and discrimination in the field prompted an international survey and research into potential solutions.

Nigeria’s new marine and blue economy ministry has promise but it must be well run.
Mounting evidence shows seismic surveys can harm a range of marine animals.

Environmental DNA provides a wealth of information for conservationists, archaeologists and forensic scientists. But the unintentional pickup of human genetic information raises ethical questions.
Marine heat waves can reach the ocean floor as well as surface waters.

El Niño can trigger intense and widespread periods of extreme ocean warming known as marine heat waves. They can devastate marine life.
The discovery of the deepest fish in a Japanese trench raises the question, what else is out there? But before the mind leaps to all things dark and spooky, take a fresh look at life in the deep sea.

The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
Considered too deep for most reef biologists, and too shallow for deep-sea researchers, most deep reefs are unprotected.
Invasive rats can fundamentally alter the functioning of surrounding marine ecosystems.
Rats are disrupting the flow of nutrients towards the sea on many tropical islands – this has consequences for fish behaviour and the wider ecosystem.
When fish like this netted cod are exposed to mercury, it accumulates in certain organs, including the lenses of their eyes.
A new study shows that a time stamp can be put on mercury that accumulates in fish eyes, offering a window into their lifetime exposure.

A study offers evidence that marine biology’s biggest stage is broken, and suggests ways to fix it.
