Deep submersible dives shed light on rarely explored coral reefs

Mesophotic corals

Just beyond where conventional scuba divers can go is an area of the ocean that still is largely unexplored. In waters this deep — about 100 to at least 500 feet below the surface — little to no light breaks through. Researchers must rely on submersible watercraft or sophisticated diving equipment to be able to study ocean life at these depths, known as the mesophotic zone.

First book published on fishes of the Salish Sea

The Rosethorn Rockfish (Sebastes helvomaculatus)

The first book documenting all of the known species of fishes that live in the Salish Sea is now available. “Fishes of the Salish Sea” is a three-volume book and is the culmination of more than 40 years of research by authors Theodore W. Pietsch, curator emeritus of fishes of the Burke Museum and University of Washington professor emeritus of aquatic and fishery sciences, and James W.

Mysterious holes in Antarctic sea ice explained by years of robotic data

A seal wearing an ocean sensor.

The winter ice on the surface of Antarctica’s Weddell Sea occasionally forms an enormous hole. A hole that appeared in 2016 and 2017 drew intense curiosity from scientists and reporters. Though even bigger gaps had formed decades before, this was the first time oceanographers had a chance to truly monitor the unexpected gap in Antarctic winter sea ice. A new study led by researchers in the UW School of Oceanography combines satellite images of the sea ice cover, robotic drifters and even seals outfitted with sensors to better understand the phenomenon.

What does the 2019 fire season look like for Washington? UW experts weigh in

Wildfire season is already upon us. In 2018, roughly 1700 fires occurred in Washington, burning 500,000 acres of forested land and immediately affecting thousands of people in rural communities. Wildfires have a larger, regional impact too – long term exposure to smoke can increase the risk of heart and lung disease, as well as increase sensitivity to asthma. So what’s in store for Washington this year as the 2019 wildfire season gets underway?
