On the top of the world

We study how the chemistry of the Arctic Ocean is shifting due to climate change.

Sampling at sea

Bi-annual cruises will allow us to measure how surface water chemistry changes through time.

MoRIS

Moored Radium In-situ Samplers will collect monthly samples between cruises.

Project Overview

Find details on our project goals and sampling plan, which includes the development of novel in-situ radium samplers.

Outreach

Learn about our collaboration with artist Diane Burko, and find out how to become involved in the project as an undergraduate researcher.

Publications

Read the latest results from our work studying radium in the Arctic.

Scientific Objective

 

ARION is a combined shipboard and mooring-based observational network for measuring radium isotopes in the Arctic Ocean in order to detect and understand long term changes in material fluxes from the Arctic shelves to the central basins.

First ARION cruise underway this fall

By lkipp | June 16, 2021

The first ARION cruise will take place this fall (Sept-Oct 2021). Team members Lauren Kipp and Adele Anderson will board the Akademik Tryoshnikov, a Russian icebreaker, for 40 days to collect surface water samples in the eastern Arctic Ocean and deploy the MoRIS samplers for the first time.
