During the annual salmon run last fall, University of Washington researchers pulled salmon DNA out of thin air and used it to estimate the number of fish that passed through the adjacent river. Aden Yincheong Ip, a UW research scientist of marine and environmental affairs, began formulating the driving hypothesis for the study while hiking on […]
The research vessel Sikuliaq will begin a long journey to Antarctica this week, marking a new era for the Seward-based ship and its crew. The ship, which has been owned by the U.S. National Science Foundation and operated by the University of Alaska Fairbanks College of Fisheries and Ocean Sciences since 2014, has largely been […]
Instruments typically used to detect the ground motion of earthquakes can also be used to identify the type of aircraft flying far overhead, research by University of Alaska Fairbanks scientists shows. That’s because aircraft sound waves also shake the ground, although to a much lesser extent. An aircraft’s type — a Cessna 185 Skywagon, for […]
The waters bordering North America could soon be inhospitable to critical marine creatures if the Northeastern Pacific Ocean continues to acidify at the current rate, a new study shows. Earth’s oceans have become approximately 30% more acidic since the industrial revolution began more than 200 years ago. Acidification changes marine chemistry and depletes key minerals that calcifying organisms, such […]
