Deep submersible dives shed light on rarely explored coral reefs

Corals that live in the mesophotic zone

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.

Tiny fishes fuel life on coral reefs

Most bottom-dwelling fish try to avoid predation through hiding or camouflage. This colorful bluebelly blenny fish scans its surroundings with its head sticking out of its hole.

In a paper published May 23 in Science, a team of international researchers from Simon Fraser University, University of Washington and other institutions reveals that the iconic abundance of fishes on reefs is fueled by an unlikely source: tiny, bottom-dwelling reef fishes.

Exploring Our Watery World at UW’s Aquatic Science Open House

On May 4th, the University of Washington held its second annual Aquatic Science Open House, inviting Seattle-area families, students, and teachers to explore the institution’s marine and freshwater science programs. The event was organized by the Students Explore Aquatic Sciences (SEAS) outreach group based in the School of Aquatic and Fishery Sciences (SAFS) and the Academic and Recreational Graduate Oceanographers (ARGO) outreach group based in the School of Oceanography.

“We’ve known for a long time that there are very low levels of arsenic in the ocean,” said co-author Gabrielle Rocap, a UW professor of oceanography. “But the idea that organisms could be using arsenic to make a living — it’s a whole new metabolism for the open ocean.”

Wisdom of Crowds: A Conversation with Andrew Berdahl

School of salmon staging at mouth of Sam Creek.

In 1906 while attending a livestock fair in Plymouth England, Sir Francis Galton witnessed an interesting contest where locals were trying to guess the correct weight of a slaughtered and dressed ox (think jellybeans in a jar, but for butchers). He examined all 800 guesses and calculated the median calling it the vox populi, or “voice of the people,” reasoning that this would cancel out outliers on either side of the true answer. Astonishingly, the median guess was extremely close–within .8%–of the weight measured by the judges and closer than any individual guess. “This started the idea of the wisdom of crowds, where if you have a whole bunch of independent guesses you can average them, cast off the errant guess on either side and hone in on the right answer,” said Dr. Andrew Berdahl one of the University of Washington School of Aquatic and Fishery Sciences’ newest faculty members.

Sea Pens: Light on the Seafloor

Orange Seapen

It’s easy to see where the orange sea pen gets its name. A soft-bodied invertebrate that lives on the ocean floor, sea pens look just like feathered quills once used for writing. And where there’s one sea pen, there are usually others – lots of them – all swaying in the ocean current gobbling up planktonic plants and animals as they drift by.
