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: Over the course of a study started in the late 60s, UC Santa Cruz researchers have discovered for the first time the purpose of the elephant seal's bizarre vocalizations. Listen to them here and find out what they mean on EurekAlert!

Heat release from stagnant deep sea helped end last Ice Age
The build-up and subsequent release of warm, stagnant water from the deep Arctic Ocean and Nordic Seas played a role in ending the last Ice Age within the Arctic region, according to new research led by a UCL scientist.

Sediment dwelling creatures at risk from nanoparticles in common household products
The review, published today in the journal Environmental Chemistry, highlights the risks posed to aquatic organisms when nanoparticles 'transform' on contact with water and as they pass from water to sediment and then into sediment dwelling organisms.

Toxic blue-green algae pose increasing threat to nation's drinking, recreational water
Blooms of toxic cyanobacteria, or blue-green algae, are a poorly monitored and underappreciated risk to recreational and drinking water quality in the United States, and may increasingly pose a global health threat.

CO2 emissions change with size of streams and rivers
Researchers have shown that the greenhouse gas appears in streams by way of two different sources -- either as a direct pipeline for groundwater and carbon-rich soils, or from aquatic organisms releasing the gas through respiration and natural decay.

Male elephant seals use 'voice recognition' to identify rivals, study finds
Male elephant seals compete fiercely for access to females during the breeding season, and their violent, bloody fights take a toll on both winners and losers. These battles are relatively rare, however, and a new study shows that the males avoid costly fights by learning the distinctive vocal calls of their rivals. When they recognize the call of another male, they know whether to attack or flee depending on the challenger's dominance status.

This week from AGU: Natural arches, Italian earthquake, Canadian rivers & research papers
Natural arches hum their health and scientists are listening For the first time, scientists have found a way to detect if the breathtaking natural arches of Utah's Canyonlands and Arches national parks are suffering from internal damage that could lead to their collapse, according to a new study in Geophysical Research Letters.

Significant breath from streams and rivers
Running streams are key sources of the greenhouse gas carbon dioxide, but why is it so? An international team of researchers, led by Umeå University, publishes the answer in the prestigious journal Nature Geoscience.
