These blue-green algae - cyanobacteria - would be the only winners from a warming ocean. Joydeep

If warming oceans leave algae hungry, we’ll go hungry too

Global warming is having a significant impact on marine life, as many marine organisms are adapted to live only within the average temperature range of their habitats. This applies to larger fish and sea…
As ocean cooling reverses, the planet will begin warming once more. Michael Seljos

Warming slowed by cooling Pacific Ocean

The cooling of eastern Pacific Ocean waters has been counteracting the warming effect of greenhouse gases. Our research, released today in Nature, shows this natural variability in ocean cycles is responsible…
Just how much bigger can they get? Chris Radburn/PA

Designing green ships, from sails to micro-bubbles

Maritime engineering is no exception in worldwide effort to save energy and protect the environment. In 2008 the International Maritime Organization, a UN agency, set up its Marine Environmental Protection…
Best served chilled: Antarctic krill (Euphausia superba) Uwe Kils/BAS

A view to a krill: warming seas may leave predators hungry

Although it is far from the power stations, roads and flight paths of the populated world, the Southern Ocean is already responding to climate change. Average sea temperatures in some parts have risen…
This eastern shovelnose stingaree was once unheard of in northern Tasmania. Now it is abundant. Peter Last

Marine life spawns sooner as our oceans warm

Warming oceans are affecting the breeding patterns and habitat of marine life, according to a three-year international study published today in Nature Climate Change. This is effectively re-arranging the…
The offshore industry need not be so dangerous if safety is put first. PA

The oil industry has yet to learn lessons of Piper Alpha

The explosions and fire that completely destroyed the North Sea oil rig Piper Alpha and cost 167 workers their lives remains the world’s worst offshore oil disaster. Saturday, July 6, marks 25 years since…
Coral are among the sea organisms susceptible to small changes in acidity. NOAA/David Burdick

Ocean acidification is chemistry, not conjecture

As a scientist working on the impact of climate change on marine ecosystems, one of my duties is to communicate my work. My main goal is to convince students, citizens, economists and politicians that…
Chagos: more marine life than practically anywhere else, and Captain Bird’s Eye is getting his hands on none of it. Anne Sheppard/Chagos Trust

The Chagos Islands are unique and worth protecting

The Chagos Islands marine protected area is the largest of its kind in the world, encircling the dozens of tiny islands of the Chagos archipelago that lie in thousands of miles of Indian Ocean between…
What’s out there? We know next to nothing about the amazing chemistry and compounds produced in the deep sea. Tim Donnelly

Sea of miracles: industrial uses for ocean biodiversity

The seafloor is our planet’s most biodiverse realm. It is in the sea that life on earth began over 3.5 billion years ago. It is in the sea where 34 of the 36 known phyla of animals remain to this day…
Ocean power can be harnessed for electricity generation using both wave energy and the tide. Scottish Government

Explainer: what is ocean energy?

Renewable ocean energy harnesses the power of the oceans to produce electricity. This can be done in several ways, but the resources that have the most immediate potential in terms of energy production…

Climate change at the dinner table

A new study confirms what most fishermen and seafood consumers are already feeling: warming oceans have already affected…

Leave the ocean garbage alone: we need to stop polluting first

Recent plans to clean plastics from the five massive ocean garbage patches could do more damage to the environment than leaving the plastic right where it is. There is no doubt that the focus on cleaning…
Despite the cold, high pressure and lack of light, the deep sea is an incredibly rich ecosystem. AAP Image/Queensland Brain Institute

Final frontiers: the deep sea

With the global population now well over seven billion people there are few remaining parts of the world relatively untouched by human activity. We assess the current state and future prospects of five…

Deep-sea microbes thrive under pressure

Microbes have been found thriving in even the deepest spot on the ocean floor. Research found the Mariana trench, nearly…
Plastic is a major threat to our seabirds and marine life - this bird has filled its stomach with plastic during the 80-90 days it lived. Ian Hutton

Plastic and politics: how bureaucracy is failing our forgotten wildlife

Seabirds: the poster children for ocean health. Fishers use them to identify fishing hot spots. Environmental and marine scientists use them as indicators of the condition of the ocean environment due…
Recent research shows an acidifying ocean is more damaging to coral than we’d hoped. Community Eye Health

Jumps in ocean acidity put coral in more peril

Ocean acidification - where the ocean becomes less alkaline as it absorbs excess CO2 from the atmosphere - has been described as the evil twin of global warming. Yet, remarkably, it is only over the past…

Abnormal hydro-heatwave explained

A number of factors contributed to the marine heatwave that affected ecology off the WA coast in 2011. A team of oceanographers…
