Coral Reef Photo

In early August of this year, University of Washington biologist Peter Ward encountered an example of the extremely rare nautilus Allonautilus scrobiculatus. Considered by Ward potentially one of the rarest species in the world, not a single one has been seen since Ward's first expedition over three decades past in 1984. Read about his latest expedition on EurekAlert!.

Video:Warming oceans may lead to Antarctic king crabs ascending to the top of the food chain for the first time in millions of years as traditional barriers to their dominance are diminished. Florida State University researchers explain why in this video and on EurekAlert!.

NSF, National Geospatial-Intelligence Agency support development of new Arctic maps
The National Science Foundation, in partnership with the National Geospatial-Intelligence Agency, is supporting development of high-resolution topographic maps of the Arctic that for the first time will provide consistent coverage of the entire globally significant region, including Alaska.

Saving coral reefs depends more on protecting fish than safeguarding locations
A new study by Wildlife Conservation Society has found that coral reef diversity 'hotspots' in the southwestern Indian Ocean rely more on the biomass of fish than where they are located, a conclusion that has major implications for management decisions to protect coral reef ecosystems.

CT scan of Earth links deep mantle plumes with volcanic hotspots
Geophysicists have detected plumes of hot rock rising through the mantle from the core-mantle boundary, and hypothesized that they remain stationary for millions of years, generating volcanic island chains as the crust moves over them. UC Berkeley and Berkeley Lab scientists now have proof of this connection, after using seismic waves from large earthquakes to map Earth's interior to obtain a CT scan of the mantle. The plumes are much fatter than expected.

The Condor
Loons return faithfully to the same wintering sites year after year
Common Loons nest on lakes across Canada and the northern US, but every winter they disperse, many to the open ocean where they're difficult to track. It's been well established that many loons return to the same nesting sites every spring, but new research in The Condor: Ornithological Applications shows for the first time that they are similarly faithful to their wintering sites.

New international standards needed to manage ocean noise
As governments and industries expand their use of high-decibel seismic surveys to explore the ocean bottom for resources, experts from eight universities or organizations say new global standards and mitigation strategies are needed to minimize the amount of sound the surveys produce and reduce risks posed to vulnerable marine life, especially in formerly unexploited areas such as the Arctic Ocean and US Atlantic coast now targeted for exploration.
