Ginny Cousens successfully defended Master’s thesis on August 25th
Ginny recently presented her Master of Science in Oceanography research titled “The Role of Biological Production in Oxygen Ventilation of Circumpolar Waters in Pine Island Bay, Antarctica” to the GSO community. Congratulations to Ginny on her excellent presentation, and successful defense!

GTK members will be participating in the GEOTRACES GP17 Expeditions!
PhD Student Mollie Passacantando and Assoc. Professor Brice Loose have received an NSF award to participate in the upcoming GP17 Expedition series. The goal of the expedition is to evaluate how deep sea and Antarctic Continental sources may feed nutrients, as well as trace elements and isotopes into the Southern Ocean and the Antarctic Circumpolar Current. The waters of the Southern Ocean are a main pathway by which the atmosphere and the deep ocean communicate.

GeoTracerKitchen takes part in GSO’s Science Saturday
The GeoTracerKitchen Lab had their own exhibit set up at GSO’s Science Saturday, a day full of exhibits open to the public to display the latest in ocean exploration, discovery, and science happening at the Narragansett Bay Campus! On display was the Breathing Ocean display, showing ocean circulation created by a cold source on one side of a seawater tank to simulate a polar environment, with a fan blowing across the top to simulate ocean winds. Also on display was the Picarro Analyzer, showing how a marsh environment has a big impact on the methane production in Earth’s atmosphere.

Freeze Tank Experiment
Progress being made with the Freeze Tank Experiment! Multiple freezes have been run over the past few months, producing exciting ice growth. After removing the ice from the tank, ice cores are taken to preserve the structure of the ice for future analysis. The core will be analyzed to aid in the investigation of how noble gases partition between sea ice and seawater.

MOSAiC Expedition
We are very thankful to have participated in the MOSAiC Expedition – a year-long icebreaker drift through the central Arctic, which begun in October 2019. The project represents nearly a decade of planning, with a total of 17 countries who participated. MOSAiC took place throughout all seasons of the Arctic environment to better understand the ocean-ice-atmosphere system.
