Stable isotopes of carbon and nitrogen from multiple species of invertebrates, teleosts, elasmobranchs, and marine mammals sampled in Cumberland Sound, 2007-2009

As the largest fish and most prolific eater in the Arctic seas, the Greenland shark is a very unique vertebrate in the Arctic ecosystem. Given their diet, Greenland sharks hold a position in the food web similar to that of polar bears. Little is known about how these sharks behave or how their behaviour might shift in response to changes in climate. Given their importance in the Arctic food web, this project is assessing the feeding ecology and behaviour of the Greenland shark under different ice conditions to determine how different environments affect this fish. This assessment involves the analysis of stable isotopes of carbon and nitrogen from multiple species of invertebrates, teleosts, elasmobranchs, and marine mammals sampled in Cumberland Sound in 2007, 2008 and 2009.
