Healthy oceans need healthy soundscapes, say marine scientists

February 12, 2021 by Kathleen Wong

marine noise pollution

By Tim Stephens, UC Santa Cruz Rain falls lightly on the ocean’s surface. Marine mammals chirp and squeal as they swim along. The pounding of surf along a distant shoreline heaves and thumps with metronomic regularity. These are the sounds that most of us associate with the marine environment. But this soundtrack of a healthy ocean no longer reflects the acoustic environment ... Continue Reading »

A surprising cycle

ocean hydrocarbon cycle

By Harrison Tasoff, UC Santa Barbara Hydrocarbons and petroleum are almost synonymous in environmental science. After all, oil reserves account for nearly all the hydrocarbons we encounter. But the few hydrocarbons that trace their origin to biological sources may play a larger ecological role than scientists originally suspected. A team of researchers at UC Santa Barbara ...

Surveys Identify Relationship between Waves, Coastal Cliff Erosion

January 28, 2021 by Kathleen Wong

Scripps Institution of Oceanography at UC San Diego researchers have uncovered how rain and waves act on different parts of coastal cliffs. Following three years of cliff surveys in and near the coastal city of Del Mar, Calif., they determined that wave impacts directly affect the base, and rain mostly impacts the upper region of the cliffs. The study appears in the ... Continue Reading »

New study reveals how fences hinder migratory wildlife in the West

January 12, 2021 by lwangdu

By Kara Manke Each year, thousands of migratory mule deer and pronghorn antelope journey northwest from their winter homes in the Green River Basin, a grassland valley in western Wyoming, to their summer homes in the mountainous landscape near Grand Teton National Park. But to reach their destination, these ungulates must successfully navigate the more than 6,000 ... Continue Reading »
