One of the most damaging invasive species in the oceans has breached a major barrier – the Amazon-Orinoco river plume – and is spreading along Brazil’s coast. Scientists are trying to catch up.
New research reveals baby clownfish like Nemo are incredible athletes, able to swim 10-50 body lengths per second. Their athletic traits support their journey from the open ocean back to the reef.
One meadow made enough sand to create a new island in 18 years.
Remote islands in the Indian Ocean are now strewn with plastic waste – the origin of this waste has until now not been established.
Considered too deep for most reef biologists, and too shallow for deep-sea researchers, most deep reefs are unprotected.
Rats are disrupting the flow of nutrients towards the sea on many tropical islands – this has consequences for fish behaviour and the wider ecosystem.
Humans are expert pattern-finders. But artificial intelligence tools are better at trawling through vast data sets to find anything from waste dumps to heat-tolerant corals.
Environment ministers from both sides are determined not to see the Barrier Reef listed as in danger. The question is – why?
Our new, world-first research provides strong evidence of a significant increase in reef manta rays in protected areas of Raja Ampat over a decade.
Black corals provide critical habitat for many creatures that live in the dark, often barren, deep sea, and researchers are learning more about these rare corals with every dive.
Mayotte is no exception to the adage “small islands, big problems”. A newly born volcano combined with poor land management and accelerating climate change has put its fabled lagoon at risk.
The oceans bordering West African countries are in grave danger from pollution; checking further degradation is crucial for human survival.
A recent paper suggested damaging climate tipping points could be closer than first thought.
Rising concern about possible environmental damage from the active ingredients in sunscreens could have ripple effects on public health if it causes people to use less of them.
Researchers have long suspected that an ingredient in sunscreen called oxybenzone was harming corals, but no one knew how. A new study shows how corals turn oxybenzone into a sunlight-activated toxin.
Marine heatwaves will happen so often that reefs will struggle to weather successive bleaching events.
The ocean is naturally noisy. Here’s what all the buzz is about.
The old ways of keeping giant clam species healthy won’t work with climate change. We need new techniques - and fast.
New research shows just 2% of the Great Barrier Reef remains untouched by bleaching since 1998. Its future survival depends on how much higher we allow global temperatures to rise.
The remarkably resilient structure is in good health, for now. But work is needed to ensure it is preserved for future generations.
