A History of Satellite Remote Sensing Research at Oregon State University

Satellite data have revealed fundamental features of the world's oceans

CEOAS faculty have been involved in every aspect of satellite remote sensing, including sensor and satellite mission design, development of algorithms for retrievals of the physical and biological variables of interest, and applications of satellite observations to study a host of oceanographic research questions.

Strange bedfellows: magnetism and climate

What's magnetism got to do with it? An OSU postdoctoral scientist joins an expedition to the Atlantic to look for climate clues.

Chuang Xuan is at sea on the research vessel JOIDES Resolution studying magnetic and climate evidence in deep-sea sediment cores.

Speaking of Plastic

Plastic doesn't belong in the ocean, but let's get real

You might have heard a few supposed facts about plastic in the ocean: 1) There is a massive swirling gyre of plastic, the “Great Pacific Garbage Patch,” between California and Japan that is twice the size of Texas; and 2) this plastic debris outweighs plankton and is growing in size. Interestingly, the scientific literature does […]

Shellfish on Acid

How will acidic water affect Oregon's shellfish industry?

“O Oysters,” said the Carpenter, “You’ve had a pleasant run! Shall we be trotting home again?” But answer came there none — And this was scarcely odd, because They’d eaten every one. — Lewis Carroll The Walrus and the Carpenter Whether or not you’re a fan of gulping down raw oysters doused with Tabasco, recent […]

OSU's growing fleet of underwater gliders monitors the Pacific Ocean

For more than half a century, oceanographers have ventured out of Newport to measure, probe and monitor the Pacific Ocean off the central Oregon Coast. And since the 1950s, these seafaring researchers have recorded about 4,000 “profiles” of the near-shore waters — surface to bottom measurements of temperature, salinity and oxygen levels that begin to […]

Dolphins Hunt Together

Watch spinner dolphins corral their quarry and work together to feed in these animations. Kelly Benoit-Bird used acoustic data of dolphins feeding at night near Hawaii. She reported her findings in the following journal article: Benoit-Bird, K.J. & Au, W.W.L. 2009 “Cooperative prey herding by a pelagic dolphin, Stenella longirostris.” Journal of the Acoustical Society […]

Genius of the Sea

Ecosystem processes hidden in deep ocean waters are falling prey to Kelly Benoit-Bird's investigations

Kelly Benoit-Bird studies ocean organisms smaller than a microchip and bigger than a luxury motor home — the tiniest crustaceans to the mightiest cetaceans. In effect, she studies just about anything that swims or drifts in the sea: copepods and krill, diatoms and dinoflagellates, siphonophores and salps, spinner dolphins and Humboldt squid, Pacific sardines and […]

Oregon has become an international center for ocean research

For the past decade, Oregon State University has boasted an oceanography program ranked among the top five in the nation, and its broad spectrum of marine and coastal research has an international reputation that few institutions can match. OSU Marine Science by the Numbers 350 OSU faculty, nearly $100 million in research, more than 150,000 […]

Uncharted Waters

Communities, engineers and scientists prepare for the next tsunami

It may come like it did the last time, in the middle of a cold and blustery January night. Suddenly the ground will begin to shake, windows will shatter, bridges collapse, the electricity will go out and parents will frantically try to find a flashlight and dig sleepy kids out of bed, ignore everything else […]

Reserve for Rockfish

Policy and science in Port Orford

Redfish Rocks is home to a diverse collection of marine species — and to a unique collaboration among fishermen, university scientists and the Oregon Department of Fish and Wildlife. The jagged reef off the shores of Port Orford, one of two pilot sites in Oregon’s developing marine reserve network, was established by coastal residents who […]

Global Ocean

Sea levels are rising. Coral reefs are under siege. “Dead zones” are proliferating. From the poles to the Equator, Oregon State University marine scientists are tackling these and other problems in their quest to understand how oceans work, how ecosystems are responding and how we can manage them. With one of the largest concentrations of […]

Living on the Fault

On a computer generated diagram of seismic profiles from Nepal and Tibet, John Nabelek traces a thin blue line. “That’s the interface between the Indian and the Eurasian tectonic plates,” he says. The earthquake-prone, mountainous terrain above it is home to an estimated 40 million people. “It is very steep. In earthquakes, landslides come tumbling […]

DNA fingerprints reveal clues to ancestry and illicit hunting of cetaceans

Scott Baker, an Oregon State University conservation geneticist and cetacean specialist whose work was featured in the Academy Award-winning documentary, “The Cove,” has been named one of four 2011 Pew Fellows in Marine Conservation.

Secret Slaughter

In the seaside village of Taiji, Japan, there’s a jarring juxtaposition: Jolly-looking tour buses shaped like happy dolphins putter up and down the streets by day, while by night fishermen secretly slaughter hundreds of panic-stricken dolphins in a nearby inlet and sell them as meat. This sinister irony permeates the Academy Award-winning movie, The Cove, […]

Depths of Discovery

A young oceanographer carries on a legacy of epic seafloor science.

The colossal clamshells caught the young scientist’s eye soon after he arrived at Oregon State University in the late 1970s. Giant bivalves the size of footballs were piled in the corners of offices and cradled in the arms of researchers walking the halls of the School of Oceanography. “I realized pretty quickly that they weren’t […]

Sensing the Seas: New equipment will monitor coastal ecosystems

Ocean science is confronted with many unknowns about the intricate interplay of physics, chemistry and biology in Earth’s vast oceans. In this era of climatic flux, better understanding of sensitive ocean systems has taken on new urgency. OSU oceanographers Jack Barthand Murray Levine are refining and testing an innovative sensing system designed to track trends in temperature, […]

Modelers explore future states of the planet

You can’t just walk into the data center in the College of Earth, Ocean, and Atmospheric Sciences (CEOAS). The sign on the door says you need a pass card. There should be another sign too: Caution, planetary experiments in progress. Inside, computer clusters churn 24/7, spinning out information about ocean currents, winds, air temperatures, ice […]

New study finds increasing acidification along the West Coast

Water that upwells seasonally along the West Coast of North America is growing increasingly acidic, according to a survey conducted in 2007 by an international team of scientists. In June, they reported finding acidified ocean water within 20 miles of the shoreline, raising concern for marine ecosystems from Canada to Mexico. Deep-ocean currents take years […]

Voracious “red devil” squid are on the move

It was like a scene from a grade-B horror film. On a gently rocking vessel in the warm waters of the Sea of Cortez, a young oceanographer earnestly watches her computer screen while colleagues lower a cable into the water.

Scientists link air and water currents as shifting conditions take their toll on the Oregon coast

In his 32 years as a crab fisherman off the central Oregon coast, Al Pazar has pulled up a lot of strange things in his pots: wolf eels, skates, huge starfish, fossilized rocks, octopi, fish that rarely stray south of Alaska, and others that prefer the warm subtropical waters off Mexico. But until July 2002, […]

Grinding Out Lessons From the Earth

When Jeremiah Oxford, a master’s student from Coos Bay, Oregon, isn’t in class or writing a paper, he puts his mind to that most unacademic of tasks: grinding rocks. Tedious as it might sound, his work in Robert Duncan’s lab in the College of Oceanic and Atmospheric Sciences isn’t a punishment. Instead, he is preparing […]
