Which is more alive: a live tree or a dead tree? Dr. Mark Harmon studies how dead trees on the forest floor can provide habitat for many living organisms.
Scientists use a large crane to gather samples from the tops of trees. These samples will be tested for turgor in an attempt to explain why trees stop growing. Featuring Dr. Barbara Bond, Dr. Rick Meinzer, and R.A. Dave Woodruff.
The diverse habitat required by salmon and other anadramous fish is often created by fallen debris in a stream. Scientists aid conifers in growing near streams to eventually become this debris. Featuring Dr. Bill Emmingham.
Mushrooms are found lots of places, such as beneath trees or on woody debris. Dr. Nancy Weber however found mushrooms in a spot most people wouldn't expect to look, in the canopy.
Scientists seek to create a method of tracking logs from stand to product using scent. In addition to developing the chemicals needed for "aroma tagging," scientists work to create an "electronic nose" to recognize the scents. Featuring Dr. Glen Murphy.
For a long time historians have looked at Lewis and Clark's journals as important sources. Now scientists are doing the same to learn about the Pacific Northwest before white settlement. Featuring: Dr. Andrea Laliberte and Dr. William Ripple
Scientists use sound wave techniques as well as NIR (near infra-red light) to determine the stiffness through density of logs. Featuring Dr. Glen Murphy.
The dangers for National Park Service rangers have been increasing. Scientists study psychology, sociology, and recreation resources to help balance the dangers of crime and hazards with the increase in demand for outdoor recreation. Featuring Dr. Jo Tynon.
Because all life on Earth begins with plants capturing energy from the sun, the living things that you see around you are essentially sunlight. Sunlight energy helps transform carbon dioxide in the air into living plant tissues made of carbon materials such as sugars, starches, and fibers.
Scientists seek to explore the relationship between land use and nitrogen levels at different places along the Calapooia River. Featuring Bill Floyd and Dr. Stephen Schoenholtz.
Earthquake tests have trouble imitating the randomness and varied nature of actual earthquakes. Scientists seek to remedy this and make buildings safer by creating dynamic tests that imitate the random nature of earthquakes. Featuring Dr. Rakesh Gupta.

High resolution, continuous records of GRAPE wet bulk density (a carbonate proxy) from Ocean Drilling Program Leg 138
provide one the opportunity for a detailed study of eastern equatorial Pacific Ocean carbonate sedimentation during the last 6 m.y.
The transect of sites drilled spans both latitude and longitude in the...
Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic
studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment
depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...
We analyzed the unsaturation ratio (U k/37 ) of long-chain ketones—a molecular sea-surface temperature (SST) indicator—concentrations of carbonate and organic carbon in sediments from Site 846 in the eastern equatorial Pacific Ocean. Based on an isotopic age model for the composite depth section of 0-46 m below seafloor and on...
The sorbed gases at all four Ocean Drilling Program Leg 139 sites (855, 856, 857, and 858) showed the unmistakable presence of thermogenic hydrocarbons. No indication of abiogenic gas was found. The evidence for the thermogenic hydrocarbons includes elevated contents of higher hydrocarbons (i.e., C₁/[C₂ + C₃] ca. 2-20), δ¹³CCH₄...
Ocean Drilling Program (ODP) Leg 138 was designed to study the late Neogene paleoceanography of the equatorial Pacific Ocean at time scales of thousands to millions of years. Crucial to this objective was the acquisition of continuous, high-resolution sedimentary records. It is well known that between successive advanced piston corer...
