1. Deadly hypoxic event finally concludes
   10-30-2006 · EurekAlert!
   The longest, largest and most devastating hypoxic event ever observed in marine waters off the Oregon Coast has finally ended, researchers at Oregon State University say. Monitoring efforts will continue, new technology will be utilized, federal funding will be sought for more work in the area, and work is already under way to identify the amounts of biological damage done by this event, the fifth "dead zone" in five years and, literally, one for the record books.

2. Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
   09-20-2007 · EurekAlert!
   Scientists begin exploring the origins of earthquakes at their source with the launch of the Nankai Trough Seismogenic Zone Experiment. On Sept. 21, the Japanese drilling vessel Chikyu departs from Shingu Port with scientists aboard, ready to log, drill, sample and install monitoring instrumentation in one of the most active earthquake zones on Earth. Situated off Japan's southwest coast, the Nankai Trough has generated large-scale earthquakes and tsunamis for millions of years.

3. Manganese Can Keep Toxic Hydrogen Sulfide Zones In Check In Aquatic Systems
   10-06-2006 · ScienceDaily
   Manganese, in trace amounts, is essential to human health. Now a research team from the University of Delaware, Scripps Institution of Oceanography, the University of Hawaii and Oregon Health and Science University has discovered that a dissolved form of the mineral also is important in waterways such as the Black Sea and Chesapeake Bay, where it can keep toxic hydrogen sulfide zones in check.

4. Red Is For Hummingbirds, Yellow For Moths
   10-07-2006 · ScienceDaily
   Biologists at the University of California, San Diego have discovered that the future of red and yellow varieties of a San Diego wildflower may depend on the fates of two different animals. They report in the current issue of the Journal of Evolutionary Biology that monkeyflowers have two different animal pollinators. The red form, common along the coast, is strongly preferred by hummingbirds, while yellow monkeyflowers, found east of I-15, are favored by hawkmoths.

   04-17-2007 · EurekAlert!
   Pacific Northwest (PNW) Research Station scientists and their colleagues have been conducting research that provides managers with a better idea of the effects -- both intended and unintended -- that forest management practices can have on landscapes. Findings from this research were published recently in a series of six invited papers in Ecological Applications, a peer-reviewed journal of the Ecological Society of America.

10. Changes in west coast marine ecosystems significant
    02-16-2007 · EurekAlert!
    The California Current system has experienced significant changes during the past decade, resulting in dramatic variations in the ecosystem, characterized by shifts in phytoplankton production, expanding hypoxic zones, and the collapse of marine food webs off the western coast of the United States. These changes, driven by new wind patterns, are consistent with predictive models of global climate change.
