Satellites show overall increases in antarctic sea ice coverWhile recent studies have shown that on the whole Arctic sea ice has decreased since the late 1970s, satellite records of sea ice around Antarctica reveal an overall increase in the southern hemisphere ice over the same period. Continued decreases or increases could have substantial impacts on polar climates, because sea ice spreads over a vast area, reflects solar radiation away from the Earth’s surface, and insulates the oceans from t
Important ocean process examined with newly developed ’BubbleCam’
The relaxing atmosphere of a walk along the shore, especially the sounds of waves breaking on the beach, has seemingly forever lured people to coastlines.
For Grant Deane and Dale Stokes, oceanographers at Scripps Institution of Oceanography at the University of California, San Diego, the seaside sounds of hundreds of millions of air bubbles bursting at the shoreline represent an important key to und
A new study of marine ecosystems suggests that the preservation of biodiversity is more than just a lofty goal – it’s an absolute necessity to keep the system healthy and prevent both local or regional extinction of multiple species.
The population balance between various fish species, their competitors and their predators are all essential to the proper functioning of the ecosystem, the study showed, and overfishing of any one species can have ripple effects that destabilize the whole
Researchers from Woods Hole, Scripps oceanographic institutes sail on new Coast Guard ice breaker to study climate, ocean changes
A University of Massachusetts Amherst geoscientist is part of a team of researchers sailing the Bering and Chukchi seas this summer, searching for clues about the sea floor history and the land bridge that once existed between what is now Alaska and Russia. The team will also explore how the disappearance of the land bridge may have affected that region
Scientists at the Hebrew University of Jerusalem have demonstrated that sea spray over the oceans contributes to cleansing air that has been polluted overland. The air pollution is washed down by rain, which occurs because the rain-suppressing effect of such pollution is significantly neutralized. An article on this research appears in the online magazine Science Express, published today.
In previous studies, Prof. Daniel Rosenfeld of the Ring Department of Atmospheric Sciences, and collea
Commercial fishing practices can reduce genetic diversity in fish populations, possibly threatening their productivity and adaptability to environmental change, new research has found.
An Australian zoologist now at the University of Melbourne, along with colleagues from the United Kingdom and New Zealand, was the first to record a decline in the genetic diversity of a commercially exploited marine species.
Their findings, published in the latest volume of the “Proceedings of the
