Alaskan Wildlife: Observations from the Aleutian Arc Expedition
A USGS-led expedition in the Aleutian Arc off Alaska will provide critical information on energy resources, underwater earthquakes and other hazards, seafloor habitats, and biological resources, including key fisheries, as well as potential seabed minerals. Though the expedition focuses on natural resources below the waves, the science team marvels at Alaska's wildlife above the waves as well.
As the R/V Atlantis makes its departure from Dutch Harbor and heads south down the Aleutian Islands, the Alaskan wildlife is abundant like no other. The upwelling that occurs along the Aleutian chain makes these waters a highly productive place and as a result, these are prime feeding grounds for marine birds. The rapid fluttering of Tufted Puffins renders these birds unforgettable as they are known for their deep diving, not flying. Nonetheless, puffins remain a fan favorite on board.
Murres and Northern Fulmars have colonies nearby and soar in the sky in the hundreds, giving the ship an elegant show to watch and an almost insurmountable task of counting them. One could not miss the graceful flying of the many Albatross species living in this area, including the Laysan and Short-Tailed Albatross, with their long wingspans and effortless gliding close to the sea surface. Cormorants and gulls are a few other bird species that have been sighted and added to our life lists!
Aside from marine birds, seagoers have found joy in watching Northern Fur Seals. As the U.S. Navy's human occupied vehicle Alvin was deployed on the second day of the expedition, several fur seals curiously swam around the submersible, diving down and resurfacing every so often to look around. Everyone on deck found delight in this spectacle. On the third day of the cruise, as the science team transited with rough weather, a humpback whale and an orca made appearances to those who were lucky enough to spot them. Needless to say, the Aleutians are home to incredible wildlife and anyone who experiences it will leave in awe of what they saw.
