Here’s the second post in the Discover magazine series on climate work with Arctica islandica off northern Norway. Al Wanamaker and Michael Carroll are looking for the most northerly populations of Arctica islandica, living at depths up to 180 metres.
Rob Witbaard and Irene Ballesta are also up there, deploying clams wired with activity loggers to look in great detail at the environmental factors driving shell growth.
You can also read about raised beaches, thought to be about 6,000 years old, that are covered with ancient shells.
Rob Witbaard and Michael Carroll help Captain Thorleif Hanssen redeploy Rob’s clam experiment.
