Recent research sheds light on the ocean’s annual ‘biological clock’ and highlights the key dynamics that make it susceptible to climate change.

Deeper ocean habitats (30-150 metres) are a key feeding ground for critically endangered hawksbill turtles.

Recent research shows how reducing overfishing is both an ecological imperative and a critical means to addressing climate change.
Puffins and many other seabirds rely on sandeels as a food source.

Many seabird colonies around UK coastlines struggle to breed because the sandeels they feed on have been overfished. The upcoming closure of sandeel fisheries will be good news for marine wildlife.

Trophy fishing is a big threat to some of the most threatened species of fish, but there are ways to adapt the sport with marine conservation in mind.
Scientists have found that hermit crabs are increasingly using plastic and other litter as makeshift shell homes.

Norway has become the first nation on earth to allow deep-sea mineral exploration. But opening this industry could put Norway in murky legal waters.

Over 200 million tonnes of sediment are transported by rivers to the sea each year, the most widespread water contaminant in the country. Its devastating impact on marine life has to be reversed.

Floodwaters pulsing into the sea normally clear within six days. But the 2022 floods in eastern Australia were different.

Artificial reefs are structures that humans put in place underwater that create habitat for sea life. A new study shows for the first time how much of the US ocean floor they cover.
Producing concrete blocks with captured carbon, like these in Brooklyn, NY., has both economic and climate benefits.

The combination of the source of the CO₂ and its end use determines its environmental and economic benefits or consequences.

Anchovies cause a stir as they mate – getting the oceans moving.
Many commercial fishing boats do not report their positions at sea or are not required to do so.

New Zealand’s new government has vowed to explore ‘blue carbon’ options for removing atmospheric CO₂ to meet net zero goals. But first we need a national strategy for this developing field of science.
Male fiddler crabs are small, with one oversized claw.

South of Cape Cod, fiddler crabs and marsh grass have long had a mutually beneficial relationship. It’s a different story in the North, where the harms can ricochet through ecosystems.
