For nearly 40 Washington State teachers attending the Olympic STEM Pathways Partnership workshop at the University of Washington in late-June, it was like Christmas had come early. Each educator sifted through a toolkit full of techy gadgets—a breadboard, ribbon cables, wires, antennas, and a microprocessor. The teachers used their cache of materials to assemble a powerful, data-collecting underwater sensor; and over the next several years, they’ll develop an approach to bring their new expertise back into the classroom.

Tiny drifting algae called diatoms generate about 20 percent of the oxygen produced on Earth each year—more than all of the world’s rainforests. A new study from the College of the Environment’s School of Oceanography and Seattle’s Institute for Systems Biology looked at how common species of diatoms will adjust to sudden and long-term increases in carbon dioxide. The scientists found that when CO2 spikes, as might happen during a sudden change in ocean currents, the diatoms produce a signaling molecule that reduces the energy-intensive process required to concentrate the carbon dioxide.

For more than a century, scientists at UW have utilized Friday Harbor Laboratories’ unique location on the shores of the Puget Sound to study a variety of marine species. With the debut of the Ocean Acidification Environmental Laboratory in 2011, research at Friday Harbor Labs expanded into monitoring the water’s pH and dissolved oxygen levels, total alkalinity, effects of ocean acidification, and strategies for adaptation.

New ocean acidification research published in late April shows a strong correlation between current ocean conditions and the dissolution of sea butterfly shells. Sea butterflies–or pteropods–play an important role in the marine food web, providing a food source for higher-level predators like salmon. The study focuses on the California Current, which stretches along the entire west coast of the United States and is a key driver of how our nearby marine ecosystems take shape and function.

Parker MacCready, professor at the School of Oceanography, finished up a stint as a Visiting Researcher at Microsoft Research last fall, utilizing the newest technology to advance the study of ocean acidification and other ocean sciences. Microsoft Research has the express goal of collaborating “with the world’s top researchers to develop technologies that help solve global challenges.” Ocean acidification is a phenomenon that will adversely affect the Puget Sound region, thus Parker spent four months partnering with the Earth, Energy, and Environment section of Microsoft Research Connections.
