Archaeologists find massive fortifications from the Iron Age
Researchers from Tel Aviv University have unearthed the remains of massive ancient fortifications built around an Iron-Age Assyrian harbor in present-day Israel.
Small islands may amplify tsunamis
Small islands, long thought to be natural tsunami barriers for coast-dwellers, may in fact amplify the waves they are supposed to break, researchers warned Wednesday.
Sea-level rise drives shoreline retreat in Hawaii
Sea-level rise (SLR) has been isolated as a principal cause of coastal erosion in Hawaii. Differing rates of relative sea-level rise on the islands of Oahu and Maui, Hawaii remain as the best explanation ...
Forecast is for more snow in polar regions, less for the rest of us
A new climate model predicts an increase in snowfall for the Earth's polar regions and highest altitudes, but an overall drop in snowfall for the globe, as carbon dioxide levels rise over the next century.
Algae declines in the water off Sydney

Changes in coastal upwelling linked to variability in marine ecosystem off California
In findings of relevance to conservationists and the fishing industry, new research links short-term reductions in growth and reproduction of marine animals off the California coast to increasing variability ...
Humble plants may save the planet
Marine ecologists call them seagrass meadows. They once wrapped Australia's coastline providing sanctuary and food for dugongs and turtles, habitats for fish to breed and myriad other ecosystem services such ...
Scientists find impact of open-ocean industrial fishing within centuries of bird bones
The impact of industrial fishing on coastal ecosystems has been studied for many years. But how it affects food webs in the open ocean―a vast region that covers almost half of the Earth's surface―has ...
When hungry, Gulf of Mexico algae go toxic
When Gulf of Mexico algae don't get enough nutrients, they focus their remaining energy on becoming more and more poisonous to ensure their survival, according to a new study by scientists from North Carolina ...
Invasive species: Understanding the threat before it's too late
(Phys.org) —Catching rides on cargo ships and fishing boats, many invasive species are now covering our shorelines and compromising the existence of our native marine life.
Local factors cause dramatic spikes in coastal ocean acidity
(Phys.org) —A new Duke University-led study has documented dramatic, natural short-term increases in acidity in a North Carolina estuary.
Model now capable of street-level storm-tide predictions
The water that surged into the intersection of New York City's Canal and Hudson streets during Hurricane Sandy—to choose just one flood-ravaged locale—was ultimately driven ashore by forces swirling hundreds ...
Report: Tsunami would swamp California's economy (Update)
If a monster earthquake struck off Alaska's coast, tsunami waves would rush toward California, crippling the nation's busiest port complex and flooding coastal communities, a report released Wednesday suggests.
