and regions at risk.But, until recently, the geological activity that leads to an earthquake like Chignik was a significant blind spot to scientists, lying hidden and inaccessible beneath the waves.Now, thanks to ongoing collaboration and development between underwater technology company Sonardyne, Scripps Institution of Oceanography and the U.S. Geological Survey (USGS), the ability to remotely monitor our restless earth is not just possible but also becoming standard practice.Using a technique called GNSS-A, an increasing amount of coastline most vulnerable to earthquake and tsunami hazards, including

much more detail than possible in this article. Zoom in on the sections relevant to your work, then come back later and explore other seal designs, such as dovetail grooves, SAE Boss seals, crush seals, rotary seals, and others that might be helpful another day on another project. In my early years at Scripps, I found the Handbook a little confusing in parts. Older, experienced engineers and machinists helped me through it. In the long time since, from inside the Arctic Circle to the bottom of ocean trenches, Parker design guidelines never once let me down. Pretty epic win-loss ratio. In the early 1980&rsquo

The company said the project represents its move from research and development into commercial operations after previously exporting power only to a microgrid at the Scripps Institution of Oceanography during a 2021–22 open-ocean deployment.The five-year agreement, running from 2026 to 2030, enables BPA to purchase up to 20 MW of energy per hour from OSU. PacWave’s offshore test site does not always operate at full capacity, but the arrangement provides

Barrels of Caustic Waste Found Off California

New research from UC San Diego's Scripps Institution of Oceanography reveals that barrels of caustic waste, thought to be related to the pesticide DDT, have created an extreme environment around them.Though the study’s findings can’t identify which specific chemicals were present in the barrels, DDT manufacturing did produce alkaline as well as acidic waste.“One of the main waste streams from DDT production was acid, and they didn’t put that into barrels,” said Johanna Gutleben, a Scripps postdoctoral scholar and the study’s first author. “It makes you
