Industrial fishing poses greater risk to marine life due to untracked activity, UC Santa Cruz researchers find

A new study led by a scientist at UC Santa Cruz’s Institute of Marine Sciences finds that blue whales, tunas, and other top predators in the northeast Pacific Ocean face greater risk of harm from industrial fishing than previously thought.

Scientists begin to crack open climate-change riddles hiding in ancient coral

An international team of researchers on an expedition co-led by UC Santa Cruz Professor Christina Ravelo collected cores of fossil coral off the coast of Hawai’i to look for signs of climate and sea-level change over the past half million years.

Scientists use Hawaiian fossils to study the past and future of climate change

This month, an international team of researchers returned to shore after a two-month-long ocean expedition exploring fossil coral reefs off the coast of Hawai’i. The fossils provide a record of past climate conditions, so scientists are using them to learn about environmental changes throughout geologic history and make predictions about the future
