In her professional career, Dawn Wright, chief scientist of the Environmental Systems Research Institute (on hiatus from Oregon State University), has mapped what lies beneath and uses that knowledge to influence sustainable coastline designs.

Beavers have long been punished by farmers because of their knack of flooding croplands and altering landscapes. But biologists are now trying to put those same skills to use on public lands -- for the benefit of salmon.
Ernestine Neitzel moved to Oregon in 1925 at the age of four and has lived her whole life on the truck farm along the Necanicum River. Her father grew vegetables that he sold at stores in nearby Seaside. After she married, she and her husband expanded the farm to include dairy cows. Over the years, she has watched as one farm after another was subdivided and developed, and the more she thought about it, the more she thought about protecting her land.
New system helps move salmon past Cougar Dam
Some of the changing social values and demands to ensure species viability that ultimately caused the collapse of national forest management plans in the 1980s and 90s have been addressed, scientists say, but other topics still have similar potential for conflict.
"Bryan was able to correlate increases in winter temperature with changes in tree ring width and growth declines," says Jeff Stone, an expert in tree diseases at Oregon State University who is also studying Swiss needle cast.
Tom Calvanese, a biologist and Oregon State University graduate student, studies the nearly 40 rockfish species that live along the Oregon coast. They're popular to look at because of their menacing spines and vibrant colors, but they're also popular for eating.
The trail is a vital part of interpretive efforts at Oregon State University (OSU)"™s Hatfield Marine Science Center (HMSC) in South Beach.
For years government agencies have bulldozed these meddlesome weeds to give the troubled shorebirds more sand. But new research from Oregon State University now shows those efforts also have unwelcome side effects. Bulldozing wipes out native plants and can further change the ecology of the beach.
Deciding to decommission logging roads isn't as simple as it might seem, said Julia Jones, a Department of Geosciences professor at Oregon State University. She's studied the hydrology of logging road runoff.
In the new study researchers led by Andreas Schmittner from Oregon State University focused on the climate during the last ice age, about 19,000 to 23,000 years ago, to estimate how sensitive the climate system is to changing amounts of CO2 (in the ice age scenario, a reduction of CO2 helped cool the globe).
The acidification of the world"™s oceans from an excess of CO2 has already begun, as evidenced recently by the widespread mortality of oyster larvae in the Pacific Northwest. Scientists say this is just a harbinger of things to come if greenhouse gas emissions continue to soar.
The study was done by researchers from Oregon State University and other agencies, and concluded that heavy loads of parasites can affect salmon growth, weight, size, immune function, saltwater adaptation, swimming stamina, activity level, ability to migrate and other issues.
Bob Dziak, an Oregon State University marine geologist based at Hatfield Marine Science Center (HMSC), said this is the second leg of deployment under the Cascadia Initiative, a $10-million project funded under the American Recovery and Reinvestment Act of 2009 to build an offshore/onshore network of seismic and geodetic (earth) stations ranging from Cape Mendocino, Calif., to Cape Flattery, Wash.
Andrew Blaustein, an ecologist at Oregon State University, said environmental factors are driving the spread of parasite infections.
The western United States has experienced increasing drought conditions in recent years "and conditions may worsen if global climate change models are accurate“ yet the country is doing little to prepare for potential catastrophe, a group of scientists said today.
Will recovery efforts in the Willamette Basin be enough to save a species that scientists fear could become extinct in 40 years? Includes text and video.
No-logging zones along state forest streams are making a difference in keeping temperatures cool for fish, according to a study issued Wednesday by Oregon State University.
A new study by Oregon State University researchers indicates that thinning Douglas firs, which gives them more room to grow and develop the old forest characteristics favored by northern spotted owls, is bad news for the threatened bird's primary prey.
Now an Oregon State University professor is studying algae strains at a series of Oregon waterways to determine whether these individual strains can produce toxins capable of sickening and killing people or whether they are nothing more than gross, smelly scums producing no greater public-health danger than swimmer's itch.
Submarine landslides triggered by major quakes on land have sent layers of sediments onto the seabed, and by dating those sediments researchers led by Chris Goldfinger, a marine geologist at Oregon State University, have calculated that the temblors rupture the ground roughly every 240 years on what is called the Cascadia Subduction Zone.
Oregon State University scientists say they've discovered an eruption of an undersea volcano about 250 miles off the Oregon Coast.
The panel of scientists took issue with a recent Science magazine report led by Andreas Schmittner of Oregon State University that looked at pollen and seafloor records of the last Ice Age that was more than 19,000 years ago.
Keen interest is growing for development of wave energy along the Oregon coast. But some officials and residents in Seaside are expressing concern about the impact of developing such renewable energy sources.
Oregon State University scientist Solomon Yim, director of the O.H. Hinsdale Wave Research Laboratory, says that each time a major tsunami hits, his $20 million lab sees an uptick in research projects from his average of $2 million in annual grants. "Before 2004, tsunamis were not on the radar screen of Americans," says Yim. That all changed with the Indonesian tsunami, and in 2005, the departments of transportation for the three western coastal states commissioned more research.
