Microplastics in Marine Mud

Ocean plastics present serious problems. Plastics choke and starve wildlife, pollute the water and degrade living conditions in coastal and island communities, introduce toxins into the marine food web that extend up to us in our seafood, damage fish stocks, and decrease overall ocean health. The “Great Pacific garbage patch” formed by the North Pacific…

Diazotrophs in the Arctic

Kendra Turk-Kubo’s research focuses on diazotrophs. Diazotrophs are microscopic organisms that have the special ability to fix nitrogen. They come in all shapes and sizes, as bacteria or archaea. Turk-Kubo talks about their individual characteristics with a fond familiarity – Trichodesmium, Nostoc, UCYN-A, Richiela, Nodularia, Crocosphaera – all diazotrophs she’s spent the last decade of…

Getting Our Fix

This post includes an explanation of the Virginia Institute of Marine Science teams work on this cruise and a summary of their two weeks of work in Barrow, Alaska. The next post will feature Kendra Turk-Kubo, a research specialist at the University of California Santa Cruz, who collaborates closely with the VIMS team. Scroll to…

A Student Perspective

From undergraduate to graduate to a recently finished Ph.D., the Virginia Institute of Marine Science (VIMS) team has a unique student perspective. These interviews were conducted and edited by Deb Greene, an educator from the Anchorage School District. Dr. Jenna Spackeen Spackeen submitted her dissertation from port the day this cruise left. Her Ph.D. generally…

Barrow and Back Again

Our cruise track so far, from Nome to Barrow Canyon Bring on the science The first transect of the cruise began this morning. We’ve transited from Nome, Alaska through the Bering Strait up the Alaskan coast to the waters off Barrow, Alaska. We’re now doing a northerly transect across Barrow Canyon into the Chukchi Sea….

Watching the Ocean Breathe

Not everyone would be excited about blue and gray dots hopping horizontally across a graph, but Laurie Juranek is. It means the amount of oxygen in the water sampled over the past 24 hours is abnormally high. The blue dots are Juranek’s data and the gray dots are from the oxygen sensor attached to the…

Underway

We are underway! The Sikuliaq left Nome Sunday evening. The scientists are set up at their stations – Burke Hales’ OSU team in the wet lab, Laurie Juranek and Miguel Goñi’s OSU teams in the main lab, the VIMS team in the analytical lab – and continuous sea water samples from beneath the ship are…
