Ms. Callaghan’s Classroom: Sampling from the Sea
This is the latest in a series of dispatches from scientists and education officers aboard the National Science Foundation’s R/V Sikuliaq. Jil Callaghan is a 6th grade science teacher at Houck Middle School in Salem, Oregon. She is posting blogs for her students while aboard the Sikuliaq as part of a teacher at sea program through Oregon State University. Read more posts here. Track the Sikuliaq’s progress here. By Jil …
Ms. Callaghan’s Classroom: Multi-coring
It was so cool to watch pieces of ice float by as we were working on deck! I’m standing next to the hose because we wash off the utensils (the metal sheet for cutting, the spatula used for scraping it into the bag, and the plastic ring) in between samples so that we don’t contaminate one layer with mud from another!

Keep your Berings Strait
Today is our first full day at sea after leaving the port of Nome yesterday morning. We’re traveling through the Bering Strait, headed toward a mooring about 30 miles off of Barrow, Alaska. (The mooring is actually that of Robert Pickart, a well known physical oceanographer who isn’t on this cruise.)
Sikuliaq Dispatch: No Place Like Nome
The man I met on the plane ride here was right when he said the roads in Nome lead to rivers and to nowhere.

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!

Hello from Sikuliaq 2016: The Dynamic Arctic
Welcome to our Dynamic Arctic blog! This will be our information hub to keep you up-to-date as we embark on a research cruise through the Beaufort and Chukchi Seas. Our journey will begin in Nome, Alaska on about August 31 and finish around October 1, 2016.

One Million Icequakes
Nestled in the Arctic is a glacier like no other. This glacier quakes once a minute creating seismic events that rattle the earth—more frequently than scientists have ever seen. Understanding why these icequakes are so common may help researchers predict future ice flow, a process that propels climate-driven sea level rise.
Restoring white Arctic will fall to future generations who never knew it
Scientists and policymakers have discussed for decades how to slow the rate of global warming and melting Arctic ice—most recently at the Paris talks—but few have discussed how to restore the ice after it is lost. That task will likely fall to future generations who not only grew up without a white Arctic but may have conflicting interests in keeping it blue, according to an analysis presented on Monday by scientists at the 2015 American Geophysical Union Fall Meeting.
