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.
Rapid coastal population growth may leave many exposed to sea-level rise
The number of people potentially exposed to future sea level rise and associated storm surge flooding may be highest in low-elevation coastal zones in Asia and Africa, according to new projections published ...
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 ...
Jellyfish experts show increased blooms are a consequence of periodic global fluctuations
Scientists have cast doubt on the widely held perception that there has been a global increase in jellyfish.
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
