An international mission to map geochemistry of the Arctic Ocean
Read this very interesting and appealing article about the U.S. Arctic GEOTRACES expedition and watch the videos included in it. This article has been prepared by the Florida International University, home institution of Dave Kadko, the chief scientist of this expedition: http://arctic.fiu.edu/
Canada Arctic GEOTRACES Expedition: Preparing and deploying sampling systems
Two videos documenting work for educational purposes on the icebreaker CGCS Amundsen as part of the Canadian Arctic GEOTRACES expedition are available below:
Preparing the Trace Metal Rosette for Deployment in the Labrador Sea
Scientists from the University of Victoria and University of British Columbia work together to prepare a specialized trace metal clean seawater sampling system to be deployed in the Labrador Sea during July 2015.
US GEOTRACES participates in the “Float Your Boat” an educational outreach program that provides young people an opportunity to learn about the changing Arctic, marine debris, and maritime careers through participation in a study of Arctic drift patterns, by sending their own toy boats to the Arctic. This project recreates an historic drift cask study conducted at the turn of the last century. Float Your Boat aims to provide students with an understanding and appreciation of their connection with the world’s oceans.
The US GEOTRACES plans to deploy over 1300 boats on the ice as drifters to track the ice movement across the Arctic. This project was featured on the Float Your Boat home page: http://floatboat.org
A short (less than a minute) video showing all the 1,300 colourful boats as they were packed in boxes for loading on board USCGC Healy is available on the following link: http://floatboat.org/node/6
Catherine Jeandel (GEOTRACES IPO senior scientist) and Virginie Sanial (PhD student at LEGOS, France) scientists participants at the French GEOVIDE cruise (GA01) are members of the NGO "Les étoiles brillent pour tous (The Stars Shine for Everybody)" in Toulouse, France. The objective of this NGO is disseminating research in confined environments such as prisons or hospitals but also in rural or inland areas.
In this context, Catherine and Virginie set up a project with the Seysses Prison (Toulouse, France). During 6 months (April-October 2014), they exchanged with prisoners (via their teachers). They did this before the cruise, during the cruise (thanks to a cruise blog accessible here, in French only) and after the cruise. The project ended with a session at the Toulouse Knowledge Festival called, La Novela, in October 2014.
We invite you to view the video below about this project shown during the festival "La Novela" (in French, subtitled in English).

We invite you to view the video below to meet three curious polar bears that investigate the cable of the Canadian GEOTRACES clean sampling system during the 2015 GEOTRACES Arctic expedition.
The video was taken by Kathryn Purdon (undergraduate student, University of Victoria, Canada) on September 16, 2015, near 75 N 150 W in the middle of the Beaufort Sea in the Arctic Ocean. The ship was located far from sea ice and land. Indeed, Arctic sea ice extent was the fourth lowest on record this year and there has been speculation that this imposes stress on polar bears which rely on the ice to hunt. They tested out the cable (which is made of a synthetic fiber similar to kevlar that is used in bulletproof vests) with their teeth. In the end the cable survived intact. The equipment was retrieved as quickly and safely as possible so the ship could move off and give the bears their space (click here to discover the equipment being deployed).
