Tracking sediments’ fate in largest-ever dam removal

Salmon are beginning to swim up the Elwha River for the first time in more than a century. But University of Washington marine geologists are watching what’s beginning to flow downstream — sediments from the largest dam-removal project ever undertaken.

The 108-foot Elwha Dam was built in 1910, and after decades of debate it was finally dismantled last year. Roughly a third of the 210-foot Glines Canyon Dam still stands, holding back a mountain of silt, sand and gravel.

Burke Museum on UW campus in Seattle shows problem with plastic

Right next to all the good stuff in the Burke Museum is a room full of bad stuff: used plastic, with its adverse impacts on the environment.

The Burke is a museum of cultural and natural history, on the University of Washington campus in Seattle. It is the repository for many of the state's most significant cultural artifacts.

It is also a museum that connects visitors to the world around them. Presently in its changing exhibit hall, plastic is the focus.

UW professor studies global warming

In the face of rising levels of human-produced greenhouse gases, one UW professor is part of a Greenland ice-drilling project that aims to better understand future global warming.

Edwin Waddington, UW professor of earth and space sciences, is one of 133 members involved in the North Greenland Eemian Ice Drilling project, working with project leader Dorthe Dahl-Jensen of the University of Copenhagen in Denmark.

Greenland ice core shows Antarctica vulnerable to warming

An international study indicates the last interglacial period more than 100,000 years ago could be a good indicator of where the planet is heading in the face of increasing greenhouse gases and warming temperatures globally.

The new results from the North Greenland Eemian Ice Drilling project, led by the University of Copenhagen in Denmark, shows that during the Eemian interglacial period 130,000 to 115,000 years ago the climate in North Greenland was about 8 degrees Celsius (14.5 degrees Fahrenheit) warmer than it is now.
