Lightning ‘superbolts’ form over oceans from November to February

The lightning season in the Southeastern U.S. is almost finished for this year, but the peak season for the most powerful strokes of lightning won’t begin until November, according to a newly published global survey of these rare events. A University of Washington study maps the location and timing of “superbolts” — bolts that release electrical energy of more than 1 million Joules, or a thousand times more energy than the average lightning bolt, in the very low frequency range in which lightning is most active.

Seagrass in Australia help students prepare for the real world

In the real world, engineers and scientists work together to conduct research and solve problems, but that is typically not the case in classrooms. But a month-long study abroad program provided an opportunity for student scientists and engineers to collaborate. University of Washington students traveled to the Queensland University of Technology in Australia, where they studied why seagrass and coral reef ecosystems are important, how to measure changes within these ecosystems and how to use robots to collect data.

Tides don’t always flush water out to sea, study shows

Jennifer Ruesink and Eli Wheat in Willapa Bay in 2007.

By area, tidal flats make up more than 50 percent of Willapa Bay in southwest Washington state, making this more than 142-square-mile estuary an ideal location for oyster farming. On some parts of these flats, oysters grow well, filling their shells with delicacies for discerning diners. But according to experienced oyster farmers, oysters raised in other parts of Willapa Bay don’t yield as much meat.

Kīlauea lava fuels phytoplankton bloom in the North Pacific Ocean

A new study co-authored by University of Washington researchers examines the effects of molten lava that flowed into the ocean as the result of the eruption of Kilauea volcano in Hawai’i from April to August 2018. UW School of Oceanography professors Virginia Armbrust and Anitra Ingalls found phytoplankton growth in the typically nutrient-poor Pacific, stimulated by high concentrations of nutrients from the lava.
