Oceanography in real-time: Undergraduates learn what it takes to do science at sea

Mud wasn’t the only thing students got their hands on. The undergraduates helped to sample the water column and ocean life at two deep locations (3,000 m and 600 m water depth) off the Oregon continental shelf, in addition to conducting a hydrographic survey along the Newport Hydrographic Line, a series of sampling stations that have been active for nearly 60 years.

Daikoku dive 2: Sulfur so good

The first day on the job is nerve-wracking for anyone, but when you’re a multimillion dollar ROV venturing into one of the most inhospitable landscapes on the planet you’d have a pretty good excuse to feel nervous. Everything yesterday with ROV SuBastian went as smoothly as we could have hoped. We all get a quick nights rest and are back ready to go at sunrise. It’s dive two for the #hydrothermalhunt and we’re making another dive at Daikoku seamount for what may be our final visit.

Return to Daikoku

After two cancelled dives in the back-arc, we transit to our northern-most destination: Daikoku seamount. The winds and seas are calmer there, and it is a chance to revisit a fascinating underwater volcano. We get the confirmation we have been hoping for at 6.30am – conditions are good enough and ROV SuBastian is ready for its first dive.

Video: Sikuliaq expedition recap

It’s been an incredible 28 days, full of good science, collaboration, and wildlife and ice viewing. Special thanks to the National Science Foundation, the R/V Sikuliaq, the University of Alaska Fairbanks, the Alaska Eskimo Whaling Commission, Oregon State University, and the Virginia Institute of Marine Science for making this trip possible

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.

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: 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 …
