“Light, sound, and the changing Arctic Ocean”<\/h2>\n

The Arctic Ocean is changing rapidly, but observing these changes beneath its ice cover is extremely difficult. Moving beyond traditional methods, optical sensing and acoustic thermometry can allow us to see how ocean temperature and marine ecosystems are changing in the Far North.<\/em><\/p>\n

The event is held in English<\/strong><\/p>\n

\n

The Arctic is the most rapidly changing region on the planet, with increasing temperatures and declining sea ice cover. Sea ice loss amplifies the temperature increase and changes the light conditions that form the foundation of marine ecosystems.\u00a0But the very presence of sea ice also makes it incredibly challenging for us to use conventional methods to observe changes in marine ecosystems and ocean temperature.<\/p>\n

The Nansen Center is leading the development of HiAOOS, a groundbreaking observation system yielding largescale estimates of ocean temperature and geo-positioning of autonomous platforms.<\/p>\n

In this event, two researchers talk about how innovative optical and acoustic techniques can be used to observe changes in primary production and ocean temperature in these inhospitable and largely unexplored waters.<\/p>\n<\/div>\n
