Sockeye salmon are evolving through natural selection to deal with a warming climate, according to a study by researchers at the National Oceanic and Atmospheric Administration.
A new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies – and, in fact, may be less severe than projected by the Intergovernmental Panel on Climate Change report in 2007.
A new study led by University of British Columbia researchers reveals how the effect of climate change can further impact the economic viability of current fisheries practices.
According to a newly publish research paper, fisheries and habitat managers in the Pacific Northwest need to be proactive if they want to blunt the likely negative effects on salmon and steelhead of ever-warming streams.
In order to separate human-caused global warming from the "noise" of purely natural climate fluctuations, temperature records must be at least 17 years long, according to climate scientists.
Fish and other sea creatures will have to travel large distances to survive climate change, international marine scientists have warned.
Each used a different combination of tools, climate indices and calculations, but all five meteorologists offering forecasts during a conference Oct. 29 in Portland agreed that “La Nina” could well influence what sort of upcoming winter the Northwest and other parts of the globe will experience.
A huge “migration” of trees has begun across much of the West due to global warming, insect attack, diseases and fire, and many tree species are projected to decline or die out in regions where they have been present for centuries, while others move in and replace them.
A massive trail of debris from the devastating tsunami that struck Japan in March of 2011 is slowly making its way across the Pacific Ocean en route to the West Coast of the United States, where scientists are predicting it will arrive in the next two to three years – right on schedule.
The highly contagious marine influenza virus, Infectious Salmon Anaemia (ISA) has for the first time been officially reported after being found in the Pacific Ocean on British Columbia’s central coast.
Oregon State University will launch a fleet of undersea gliders in 2012 and deploy new moored ocean-observing platforms beginning the following year as part of the $386 million Ocean Observatories Initiative.
The Department of the Interior this week released a report that assesses the status of scientific information available to help understand the impacts of climate change and other stressors on U.S. freshwater resources and calls for modernization of systems to help monitor and sustain water supplies.
La Niña, which contributed to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into winter.
U.S. commercial fishermen landed 8.2 billion pounds of seafood in 2010, valued at $4.5 billion, an increase of 200 million pounds and more than $600 million in value over 2009, according to a new report released by NOAA.
Scientists can now remotely monitor the ocean’s changing chemistry with help from some of the five-foot-tall Argo floats that drift with deep ocean currents and transmit data via satellite back to land.
Warming streams could spell the end of spring-run chinook salmon in California by the end of the century, according to a study by scientists at University of California Davis, the Stockholm Environment Institute and the National Center for Atmospheric Research.
The Herring School Workshop — a three-day conference this week at British Columbia’s Simon Fraser University, Burnaby campus — brought several groups together to digest and discuss the dismal fate of herring in the Pacific Northwest.
A new Simon Fraser University-related study confirms sea lice from salmon farms are compromising wild fish populations.
It is based on the most comprehensive examination of sea lice from salmon farms and wild salmon dynamics in British Columbia to date.
Worldwide, 2010 was one of the two warmest years on record, according to the 2010 State of the Climate report, which NOAA released last week.
An unprecedented decade-long study of apex predators in the Pacific Ocean found a wider range of distribution among some species than previously thought, unknown relationships between other species, and the importance of biological “hotspots” to the survival of most of these sea creatures.
NOAA’s Climate Prediction Center this week said a transition from La Niña to El Nino/Southern Oscillation-Neutral conditions occurred during May 2011 as indicated by generally small sea surface temperature anomalies across the equatorial Pacific Ocean.
A newly released Washington Department of Ecology study on PCBs in the Spokane River concludes that significant reductions in polychlorinated biphenyls levels have occurred over the last two decades but concentrations still don’t meet state and Spokane Tribal standards.
Facebook is well-known for connecting friends, publicizing events and allowing people ample space to procrastinate online.
A study of one of the largest watershed councils in Portland shows some inequities and a disproportionate representation by the city’s wealthier, well-connected, and liberal residents.
El Niño and its partner La Niña, the warm and cold phases in the eastern half of the tropical Pacific, play havoc with climate worldwide. Predicting El Niño events more than several months ahead is now routine, but predicting how it will change in a warming world has been hampered by the short instrumental record.
