Trace metal chemistry: less is more

Dr. Tim Conway from University of South Florida brings a wealth of understanding of trace metals...

One billion liters of seawater would be required to gather just 25 grams of iron, yet this trace element is essential to every form of life on the planet.  A group of scarce but biologically important elements in the ocean, referred to as trace metals, can either limit the growth of organisms or be toxic, depending on the concentration.  Dr. Tim Conway brings a wealth of understanding of trace metals, in part due to extensive interaction with the International GEOTRACES program, a study of the marine biogeochemical cycles of trace elements and their isotopes...

Polar bears investigate GEOTRACES Equipment

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).

Float Your Boat outreach project

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.

FloatBoat

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
