Going against the trend
Global warming has affected the entire planet’s surface, except for one particular area of the ocean, which until 2015 had bucked the trend. A research team has now unraveled what was going on.

Shelf sediments, freshwater runoff from rivers brings more carbon, nutrients to North Pole
Freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift—a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.

Researchers find new ways for coral reef ecosystems to grow
Particulate organic matter from the open ocean has a bigger-than-expected role in the growth and health of coral reefs, say researchers studying declining coral reefs in Hawaii.

Deep diving robots find warming accelerating in South Pacific Ocean waters
The coldest, near-bottom South Pacific waters originating from Antarctica are warming three times faster than they were in the 1990s, according to new research analyzing data from deep-diving ocean robots and research cruises.

New early warning system could protect vulnerable islands from flooding
A recently developed early warning system can forecast floods on coral-lined coasts worldwide and could help save residents of low-lying island nations from unprecedented disaster, according to researchers.

Ms. Callaghan’s Classroom
Hi everyone, my name is Jil Callaghan and I’m a 6th grade science teacher at Houck Middle School. I’ll be posting content for my students – who will be taught by Ms. Wright until my return in October – intermittently throughout the trip about the science done onboard. I’m looking forward to teaching from such a unique place!

An Arctic fixation
Nitrogen fixation has always been thought to require warmth and a lot of light. But it turns out that’s not true. Surprisingly, nitrogen fixation is happening in the cold waters of the Chukchi Sea. Researchers found this to be the case during an Arctic research cruise in the summer of 2011. Is this a new phenomenon, or just newly noticed?
Getting there
If you look long enough, you’ll see it: Alaska is the silhouette of a scraggly old man. His face juts out defiantly into the cold of the Arctic Circle, neck stretched, as if willing the rest of the North American continent to follow across the finish line of the Bering Strait. He has sunken eyes, a huge nose and chin, and a long, thin beard of Aleutian Islands. The left nostril – that’s where we’re going. Nome.

A note on Arctic sea ice loss
This is the latest in a series of dispatches from scientists and education officers aboard the National Science Foundation’s R/V Sikuliaq. Read more posts here. Track the Sikuliaq’s progress here. By Kim Kenny We probably won’t see much of this view during our trip – fragments of ice in the ship’s wake, a thin white sheet stretching to the horizon. We’re more likely to see the endless blue of 2°C …

Less ice, more food?
This is the latest in a series of dispatches from scientists and education officers aboard the National Science Foundation’s R/V Sikuliaq. Read more posts here. Track the Sikuliaq’s progress here. By Kim Kenny An introduction to the research Two teams will do separate but related scientific work aboard the Sikuliaq over the next month. The following is an overview of their proposed research and what they expect to find: Dr. …
