Abundance and distribution of narwhals (Monodon monoceros) on the summering grounds in Greenland between 2007-2019

Frontiers in Marine Science
Narwhal abundance in West Greenland (WG) and East Greenland (EG) was estimated from aerial surveys conducted between 2007 and 2019 at their summer grounds.

Chronicles in ivory: estimating the age of narwhals (Monodon monoceros) through stochastic modeling of seasonally varying trace elements

Frontiers in Marine Science
IntroductionAge estimation is an important tool for understanding the life history of animal populations, and several techniques have been developed, each with its own strengths and limitations.MethodsIn this study, we apply a novel age estimation method

Strange attractor of a narwhal (Monodon monoceros)

Strange attractor of a narwhal (Monodon monoceros)
Detecting structures within the continuous diving behavior of marine animals is challenging, and no universal framework is available. We captured such diverse structures using chaos theory. By applying time-delay embedding to exceptionally long dive records (83 d) from the narwhal, we reconstructed the state-space portrait.

Creating a Health Index for Narwhal (Monodon monoceros) in the Canadian Arctic

This thesis looks at the health of narwhal, Monodon monoceros from several perspectives. A critical review examines current knowledge of narwhal health at an individual and population level. Information on health parameters is a necessary input for monitoring plans that provide information for the conservation and management of Arctic marine mammal ...
