Study recommends ongoing assessment of impact of offshore wind farms on marine species
Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. In a recent paper, University of Maryland Center for Environmental Science researcher Helen Bailey reviews the potential impacts of offshore wind developments on marine species and make recommendations for future monitoring and assessment as interest in offshore wind energy grows around the world.

Amphibians being wiped out by emerging viruses
Scientists tracing the real-time impact of viruses in the wild have found that entire amphibian communities are being killed off by closely related viruses introduced to mountainous areas of northern Spain. Researchers from UCL, Zoological Society of London and Queen Mary University of London in the UK, and the National Museum of Natural Sciences in Madrid, Spain found the viruses are causing severe disease and mass deaths in many amphibian species sampled, including frogs and salamanders.

Amphibian communities collapse in wake of viral outbreak
Two closely related viruses that have been introduced to northern Spain in recent years have already led to the collapse of three different species of amphibian -- the common midwife toad, the common toad, and the alpine newt -- in the protected area of Picos de Europa National Park. In all, six amphibian species have suffered from severe disease and mass mortality and researchers say that the viruses appear to be on the move.

Rivers flow differently over gravel beds, study finds
River beds, where flowing water meets silt, sand and gravel, are critical ecological zones. Yet how water flows in a river with a gravel bed is very different from the traditional model of a sandy river bed, according to a new study that compares their fluid dynamics. The findings establish new parameters for river modeling that better represent reality, with implications for field researchers and water resource managers.

Microfossils reveal warm oceans had less oxygen, Syracuse geologists say
Researchers in Syracuse University's College of Arts and Sciences are pairing chemical analyses with micropaleontology -- the study of tiny fossilized organisms -- to better understand how global marine life was affected by a rapid warming event more than 55 million years ago. Their findings are the subject of an article in the journal Paleoceanography.

Satellite eyes first major Atlantic Hurricane in 3 years: Gonzalo
Hurricane Gonzalo has made the jump to major hurricane status and on Oct. 15 was a Category 4 storm on the Saffir-Simpson Hurricane Scale. NOAA's GOES-East satellite provided imagery of the storm. According to the National Hurricane Center, Gonzalo is the first category 4 hurricane in the Atlantic basin since Ophelia in 2011.

New study shows the importance of jellyfish falls to deep-sea ecosystem
This week, researchers from University of Hawai'i, Norway, and the UK have shown with innovative experiments that a rise in jellyfish blooms near the ocean's surface may lead to jellyfish falls that are rapidly consumed by voracious deep-sea scavengers. Previous anecdotal studies suggested that deep-sea animals might avoid dead jellyfish, causing dead jellyfish from blooms to accumulate and undergo slow degradation by microbes, depleting oxygen at the seafloor and depriving fish and invertebrate scavengers.

Could sleeper sharks be preying on protected Steller sea lions?
Pacific sleeper sharks, a large, slow-moving species thought of as primarily a scavenger or predator of fish, may be preying on something a bit larger -- protected Steller sea lions in the Gulf of Alaska. A new study has found the first indirect evidence that this cold-blooded shark that can grow to a length of more than 20 feet -- longer than a great white shark -- and may be an opportunistic predator of juvenile Steller sea lions.

Dolphin 'breathalyzer' could help diagnose animal and ocean health
Alcohol consumption isn't the only thing a breath analysis can reveal. Scientists have been studying its possible use for diagnosing a wide range of conditions in humans -- and now in the beloved bottlenose dolphin. In a report in the American Chemical Society journal Analytical Chemistry, one team describes a new instrument that can analyze the metabolites in breath from dolphins, which have been dying in alarming numbers along the Atlantic coast this year.
