In 2016 dr. Chris McKnight approached Artinis with the idea to measure NIRS under water on wild animals. Initially there was some skepticism, since our devices are not intended to be taken underwater, let alone on a wild animal. However, we really liked the challenge and together with the Sea Mammal Research Unit (SMRU) of the University of St. Andrews we created a submersible NIRS-sensor specifically for the seals.
