Europe needs coastal adaptation measures to avoid catastrophic flooding by the end of the century
Coastal floods could impact up to 3.65 million people every year in Europe by 2100, according to a new study.

Melt-rate of West Antarctic Ice Sheet highly sensitive to changes in ocean temperatures
Melting of ice shelves in West Antarctica speeds up and slows down in response to changes in deep ocean temperature, and is far more variable than previously thought, according to new research.

Scientists trace atmospheric rise in CO2 during deglaciation to deep Pacific Ocean
How carbon made it out of the ocean and into the atmosphere has remained one of the most important mysteries of science. A new study, provides some of the most compelling evidence for how it happened -- a 'flushing' of the deep Pacific Ocean caused by the acceleration of water circulation patterns that begin around Antarctica.

Sea stars critical to kelp forest resilience
A study by a resource and environmental management researcher reveals that sunflower sea stars play a critical role in the resilience of B.C.'s kelp forests, which are among the most productive ecosystems on Earth. Similar to land-based forests, kelp forests provide essential habitat for species and also help remove CO2 from the atmosphere.

Ice sheets of the last ice age seeded the ocean with essential nutrient silica
New research led by glaciologists and isotope geochemists has found that melting ice sheets provide the surrounding oceans with the essential nutrient silica.

Back to the future of climate change
Researchers are looking to the geologic past to make future projections about climate change. Their research focuses on the ancient Tethys Ocean (site of the present-day Mediterranean Sea) and provides a benchmark for present and future climate and ocean models.

'Biological passport' to monitor Earth's largest fish
Whale sharks, the world's largest fish, roam less than previously thought. This new study used stable isotope analysis to demonstrate that whale sharks feeding at three disparate sites in the Western Indian Ocean and Arabian Gulf rarely swim more than a few hundred kilometers north or south from these areas according to researchers.

Effective method to control algae growth on Hawaiian coral reefs
Researchers have found a management approach that combining manual removal and outplanting native urchin was effective at reducing invasive, reef smothering macroalgae by 85 percent on a coral reef off O'ahu, Hawai'i.

Models may help reduce bycatch from longline fishing
Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after becoming snagged or entangled in longline fishing gear. New models may help reduce the threat by giving regulatory agencies a new tool to predict the month-by-month movements of longline fleets on the high seas and determine where and when by-catch risks are greatest.

Expedition probes ocean's smallest organisms for climate answers
In August a team of scientists is sailing 200 miles to the northeastern Pacific Ocean with advanced robotics and other instruments on a month-long quest to investigate plankton and their impact on the carbon cycle.

Baby sea snails ride waves into shallower waters
The warming ocean may cause the larvae of bottom-dwelling snails to hatch earlier in the spring, when waves are larger, potentially impacting their ability to survive and serve as food for other sea creatures. A new study sheds new light on the sensory organs the snail larvae use to feel -- and perhaps even hear -- whether the water is turbulent or wavy, and improve their odds of being carried to a good habitat where they can settle down as adults.

Pacific Ocean's effect on Arctic warming
New research shows that changes in the heat flow of the northern Pacific Ocean may have a larger effect on the Arctic climate than previously thought.

Earth at risk of heading towards 'hothouse Earth' state
An international team of scientists is showing that even if the carbon emission reductions called for in the Paris Agreement are met, there is a risk of Earth entering what the scientists call 'hothouse Earth' conditions.

Possible connection between U.S. tornado activity, Arctic sea ice
The effects of global climate change taking place in the Arctic may influence weather much closer to home for millions of Americans, researchers report.

Disease is threatening the most plentiful starfish in Antarctica
A study led by experts from the University of Barcelona's Faculty of Biology and Institute for Research on Biodiversity (IRBio) have identified a disease that is affecting the starfish Odontaster validus, one of the most common species on the Antarctic sea floor.

Mapping blue carbon in mangroves worldwide
Mangroves are tropical forests that thrive in salt water and found in a variety of coastal settings worldwide. Mangroves store greater amounts of carbon than any other terrestrial ecosystem, which helps reduce carbon dioxide and greenhouse gases in the atmosphere. When carbon is stored in the ocean or coastal ecosystems, it is called blue carbon. However, a more precise estimate of how much blue carbon is stored by mangroves has not been available until recently.

Some corals might adapt to climate changes
New research shows that not all corals respond the same to changes in climate. The study looked at the sensitivity of two types of corals found in Florida and the Caribbean and found that one of them - -mountainous star coral -- possesses an adaptation that allows it to survive under high temperatures and acidity conditions.

Degrading plastics revealed as source of greenhouse gases
Researchers have found that several greenhouse gases are emitted as common plastics degrade in the environment. Their study reports the unexpected discovery of the universal production of greenhouse gases methane and ethylene by the most common plastics when exposed to sunlight.

Fishing fleets travelling further to catch fewer fish
Industrial fishing fleets have doubled the distance they travel to fishing grounds since 1950, which means that they are now able to reach 90 percent of the global ocean, but are catching only a third of what they did 65 years ago per kilometer traveled.

A soft, on-the-fly solution to a hard, underwater problem
Studying the animals that live in the deep ocean is notoriously difficult, especially because the underwater equipment that exists for sampling them is designed for marine oil and gas exploration and frequently damages the delicate creatures they're trying to capture. Now, researchers have created a soft, flexible sampling device that interacts with delicate marine life gently, and can be 3D printed directly on board ships, greatly increasing the variety of animals that can be collected in one expedition and reducing costs and time.
