This item was filled under Climate
It's what Bill Patzert, a climatologist and oceanographer at NASA's Jet Propulsion Laboratory, likes to call a "La Nada" -- that puzzling period between cycles of the El Ni?o-Southern Oscillation climate pattern in the Pacific Ocean when sea surface heights in the equatorial Pacific are near average....

Plastic found in nine percent of ‘garbage patch’ fishes: Tens of thousands of tons of debris annually ingested

This item was filled under Climate
The first scientific results from an ambitious voyage led by a group of graduate students from Scripps Institution of Oceanography at UC San Diego offer a stark view of human pollution and its infiltration of an area of the ocean that has been labeled as the "Great Pacific Garbage Patch."...

Scientists study earthquake triggers in Pacific Ocean

This item was filled under Climate
New samples of rock and sediment from the depths of the eastern Pacific Ocean may help explain the cause of large, destructive earthquakes similar to the Tohoku Earthquake that struck Japan in mid-March. Nearly 1,500 meters (almost one mile) of core collected from the ocean floor near the coast of Costa Rica reveal detailed records of approximately two million years of tectonic activity along a seismic plate boundary....

Heavy metal meets hard rock: Battling through the ocean crust’s hardest rocks

This item was filled under Climate
Scientists and drillers recovered a remarkable suite of heat-tempered basalts that provide a detailed picture of the rarely seen boundary between magma and seawater. These samples were collected during a return to ODP Hole 1256D, one of the deepest "hard rock" penetration sites of scientific ocean drilling. ODP Hole 1256D has been stabilized, cleared to its full depth, and primed for further deepening....

Arctic melting will affect the migratory strategies of seabirds

This item was filled under Climate
A study of kittiwakes (Rissa tridactyla) in the arctic region provides the first data on the migratory patterns of this seabird species and analyses its capacity to respond to environmental changes. The kittiwake is one of the most emblematic marine species of the arctic area, and evidence suggests that rising temperatures at the north pole over the coming decades will have a dramatic impact on populations of this bird....

Preserving the ‘Life Mud’ of a California Estuary [Feature]

This item was filled under News
At the Elkhorn Slough National Estuarine Research Reserve (NERR), a 1,700-acre tidal salt marsh inland of Monterey, California, kismet recently came calling in the form of a $4.5 million grant from NOAA through the American Recovery and Reinvestment Act. The grant made possible the recent construction of an experimental underwater retaining wall, called a “sill,” that’s designed to slow the fast tidal currents that are stripping a portion of the estuary of its mud bottom in a process known as tidal scour.

Clinker geochronology, the first glacial maximum, and landscape evolution in the northern Rockies

This item was filled under Climate
Scientists have developed and successfully carried out a novel, extraordinary technique for learning how efficiently river channels cut and increase local topographic relief: They have used the exposure of "clinker" deposits in combination with highly refined dating techniques....
