Centuries before modern science, humans traveled, exploited, contemplated and celebrated the seas as explorers, fishermen, whalers, merchants, poets, storytellers, musicians and philosophers. Two new courses sponsored by OSU’s Spring Creek Program and Environmental Leadership Institute will delve into this ancient human-ocean relationship.
Whether or not you’re a fan of gulping down raw oysters doused with Tabasco, recent declines in the succulent Northwest shellfish are cause for alarm. That’s because the chemical changes in seawater that are harming oysters could have far-reaching effects on other ocean species as well.
If you separate predators from their prey, you get more prey. Now that simple relationship has been used to explain one of the most important annual events in the ocean: the North Atlantic spring phytoplankton bloom.
In some of Earth’s most extreme environments — Antarc- tica’s frigid ice fields, Yellowstone’s sulfuric hot springs, Crater Lake’s lightless depths, the oceans’ deep-sea basalts — Stephen Giovannoni has discovered thriving communities of bacteria. As the holder of the Emile F. Pernot Distinguished Professorship in Microbiology, he has discovered some of the most abundant life forms on the planet.
For more than half a century, oceanographers have ventured out of Newport to measure, probe and monitor the Pacific Ocean off the central Oregon Coast. And since the 1950s, these seafaring researchers have recorded about 4,000 “profiles” of the near-shore waters — surface to bottom measurements of temperature, salinity and oxygen levels that begin to tell us how the world’s largest ocean influences everything from our weather to fisheries.
