Project to save the Belize coast provides valuable framework
A coastal zone management plan designed to safeguard Belize's natural assets has produced a win-win opportunity for people and the environment, providing a valuable framework for other coastal nations around the world where overfishing, development, and habitat degradation are increasingly serious problems.

Coral gardening is benefiting Caribbean reefs, study finds
A new study found that Caribbean staghorn corals (Acropora cervicornis) are benefiting from 'coral gardening,' the process of restoring coral populations by planting laboratory-raised coral fragments on reefs.

Seawalls: Ecological effects of coastal armoring in soft sediment environments
For nearly a century, the O'Shaughnessy seawall has held back the sand and seas of San Francisco's Ocean Beach. At work even longer: the Galveston seawall, built after America's deadliest hurricane in 1900 killed thousands in Texas.

Summer sea ice melt in the Arctic
Earlier this year Arctic sea ice sank to a record low wintertime extent for the third straight year. Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic's oldest and thickest sea ice.

Challenging prevailing theory about how deep-sea vents are colonized
Despite being relatively close together, two recently discovered hydrothermal vent fields in the Gulf of California host very different animal communities. This finding contradicts a common scientific assumption that neighboring vents will share similar animal communities, and suggests that local geology and vent-fluid chemistry are important factors affecting vent communities.

Strength of tectonic plates may explain shape of the Tibetan Plateau
Geoscientists have long puzzled over the mechanism that created the Tibetan Plateau, but a new study finds that the landform's history may be controlled primarily by the strength of the tectonic plates whose collision prompted its uplift. Given that the region is one of the most seismically active areas in the world, understanding the plateau's geologic history could give scientists insight to modern day earthquake activity.

Ancient Italian fossils reveal risk of parasitic infections due to climate change
In 2014, a team of researchers found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes. Now, an international team has found that rising seas could be detrimental to human health on a much shorter time scale.

Could sharks help save shipping industry billions?
Whales, sharks, butterflies and lotus leaves might together hold the secret to saving the shipping industry millions and help save the planet, according to a marine biologist.

Coral reefs in the Gulf of Aqaba may survive global warming, new study finds
Coral reefs in the Red Sea’s Gulf of Aqaba can resist rising water temperatures, suggests new research. If they survive local pollution, these corals may one day be used to re-seed parts of the world where reefs are dying. The scientists urge governments to protect the Gulf of Aqaba Reefs.

A super-algae to save our seas? Genetic engineering species to save corals
Solutions to climate change, and particularly its effects on the ocean, are needed now more than ever. Coral bleaching caused by climate change is a huge threat to coral reefs. Recent extreme bleaching events have already killed corals worldwide and permanent destruction of reefs is projected within the century if immediate action is not taken. However, genetically engineering a group of microalgae found in corals may enhance their stress tolerance to ocean warming and save coral reefs.

Shifting storms to bring extreme waves, seaside damage to once placid areas
The world's most extensive study of a major stormfront striking the coast has revealed a previously unrecognised danger from climate change: as storm patterns fluctuate, waterfront areas once thought safe are likely to be hammered and damaged as never before.

Sea cave preserves 5,000-year snapshot of tsunamis
Scientists digging in a sea cave in Indonesia have discovered the world's most pristine record of tsunamis, a 5,000-year-old sedimentary snapshot that reveals for the first time how little is known about when earthquakes trigger massive waves.

Sea temperature changes contributing to droughts
Fluctuations in sea surface temperature are a factor in causing persistent droughts in North America and around the Mediterranean, new research suggests.

Did life begin on land rather than in the sea?
A new discovery pushes back the time for the emergence of microbial life on land by 580 million years and also bolsters a paradigm-shifting hypothesis that life began, not in the sea, but on land.

Key to speeding up carbon sequestration discovered
The slow part of a chemical reaction that allows carbon to be sequestered in the ocean has now been identified by researchers, who have demonstrated how to speed it up with a common enzyme.

Stronger winds heat up West Antarctic ice melt
Stronger winds 6000kms away on the East Antarctic, have generated waves that circle the continent at almost 700kmh. When these waves meet the steep underwater topography of the West Antarctic Peninsula they push warm water under the ice shelves. This helps explain the increased ice melt in this region that can lead trillion tonne ice shelves, like Larsen C, to break away from the continent.

Record-breaking marine heatwave powered by climate change cooks Tasmania's fisheries
Climate change has warmed the waters east of Tasmania at four times the speed of the global average. But the heatwave of the southern summer of 2015/2016 was something exceptional, damaging fisheries and bringing new species to the island. It's a sign of things to come, say the researchers examining these events.

Fossil site shows impact of early Jurassic's low oxygen oceans
Using a combination of fossils and chemical markers, scientists have tracked how a period of globally low ocean-oxygen turned an Early Jurassic marine ecosystem into a stressed community inhabited by only a few species.

Deep-sea coral reefs discovery in depths of the North-Pacific
Scientists had long believed that the waters of the Central and Northeast Pacific Ocean were inhospitable to certain species of deep-sea corals, but a marine biologist's discovery of an odd chain of reefs suggests there are mysteries about the development and durability of coral colonies yet to be uncovered.

Why Japan's coastal zones might be disappearing due to climate change
Climate change can cause a range of effects on coastal environments, such as a decrease in sediment supply, changes in the intensity and frequency of extreme events, and changes in sea levels and wave climate. The estimation of changes due to climate change is a major issue for future coastal management decisions.
