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!.

Where iron and water mix
A new study demonstrates that chemical-laden plumes erupted from vents at one section of Mid Ocean Ridge in the southeast Pacific can be traced all the way across the Pacific for more than 4,000 kilometers. It also shows how the iron can be brought to the surface oceans of Antarctica where it has the potential to serve as a key life-sustaining micronutrient, supporting removal of carbon from the sunlit upper waters of that ocean.

Assessing quality of flowing waters with DNA analyses
The quality of waters can be assessed using of the organisms occurring therein. This approach often results in errors, because many species look alike. Therefore, new methods focus on DNA analyses instead. Biologists at the Ruhr-Universität Bochum have optimized the process so that they are now able to identify many organisms at once in a quick and reliable manner using short DNA sequences. The results have been published in the PLOS ONE magazine.

Global trends show seabird populations dropped 70 percent since 1950s
UBC research shows world's monitored seabird populations have dropped 70 percent since the 1950s, a stark indication that marine ecosystems are not doing well.

Integrating past warm climate data, scientists hone future sea-level rise predictions
In a recent review of the science on past sea-level rise and climate change, climate scientists including Robert DeConto of the University of Massachusetts Amherst survey modeling and other methods used to reconstruct past sea levels and say we are verging on a new era of understanding how quickly the Greenland and Antarctic ice sheets may respond to warming, and what rates of sea-level change might accompany such change.

Human activities, shifts in local species reshaping coastal biodiversity
While human activities have caused extinctions across the globe, your favorite beach or diving site may actually be home to as many, or more, species then it was a few decades ago. That's the conclusion of a synthesis of 50 years of marine biodiversity data conducted by University of British Columbia researchers.

Global sea levels have risen 6 meters or more with just slight global warming
A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years. What is most concerning is that amount of melting was caused by an increase of only 1-2 degrees (Celsius) in global mean temperatures.

Managing mining of the deep seabed
The International Seabed Authority is meeting on July 15 to decide on a regulatory framework for mining in the deep-sea floor. In a paper published this week in Science, researchers from the Center for Ocean Solutions and co-authors from leading institutions around the world propose a strategy for balancing commercial extraction of deep-sea resources with protection of diverse seabed habitats.

New study showed spawning frequency regulates species population networks on coral reefs
New research on tropical coral reef ecosystems showed that releasing larvae more often is beneficial for a species' network. The study on reproductive strategies is critical to assess the conservation of coral reef ecosystems worldwide.

New database documents submarine landslides
Submarine landslides, also known as mass transport deposits (MTDs), are common in marine environments and pose risks to coastal communities and offshore infrastructure. This new 332-point database presented by Lorena Moscardelli and Lesli Wood is drawn from studies of multiple MTDs around the world. Understanding these MTDS, they write, will help determine the extent of ancient submarine landslides and contribute to the development geo-models for forecasting future submarine slides.
