Expedition Team in the Northwest Passage
Our experts are here to safeguard both explorers and the pristine environment. They serve as your invaluable hosts throughout your expedition cruise.
“The oceans are full of fascinating life forms, from birds to plankton, from fish to seals to whales – and I love to help our guests learn to observe all the diversity of life on their route.”
- Mario Acquarone, Expedition Team Leader
Unmatched expertise
Expedition Teams at Hurtigruten represent the best of the best. The Expedition Team Leader and Assistant Expedition Leaders are experts on safety and sustainability, making sure your exploration of these remote destinations is done right.
Together with guest lecturers and scientists, they will enhance your voyage with first-hand knowledge and fascinating insights, ensure your complete safety during landings, and guarantee the lightest possible footprint in this pristine environment.
Leading and teaching
During your discovery of the Northwest Passage, your Expedition Team will lead the way on landings, short hikes and small boat cruises. Briefings occur before each landing, making you aware of any potential risks and of strict protocol regarding local wildlife.
Both on and off the ship, lectures are held on a wide variety of specialist topics. These may include:
- exploration history
- flora and fauna (polar bears)
- geology and oceanography
- sea ice and glaciers
- marine mammals and birds
- culture and climate
- photography and storytelling
