Ms. Callaghan’s Classroom: Walking on Ice

As the timing of our science projects got shifted from encountering ice and equipment that didn’t always perform as expected, we ended up with time to allow a side trip to go and walk around on a piece of sea ice.

Earth’s expanding crust swallowed beneath Aleutians

Sometimes, a great idea arrives ahead of its time. A person squints at a raw landscape, thinks about it in his bunk on a heaving ship, dreams of it. He scribbles a diagram. He remains quiet years later as others rediscover the same thing.

Sikuliaq week 3 recap: the home stretch

We’re on the home stretch! Much of the scientific equipment has already been packed and the mood has changed from a final scramble to squeeze every bit of data out of ship time as possible, to a subdued transit lull in which people are catching up on sleep, tying loose ends, and coming to terms with wrapping up this 28 day cruise.

Ms. Callaghan’s Classroom: The Underwater Flying Glider

What’s a glider? It is an underwater robot that “flies” around the sea going from the surface to the bottom of the seafloor collecting different types of science data.

Sikuliaq week 2 recap

We’ve done a lot of science this week! Since the last update, we’ve successfully towed the super sucker, started multi-coring, and upped our CTD tally to a whopping 87 casts, plus all the continuous surface underway data we’ve collected while steaming between sites. The scientists have some preliminary results and ideas about where they’d like to visit again (the beginning of the Wainwright line is of particular interest).

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.)

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!
