The most obvious indicator of such change is the dramatic reduction of seasonal sea-ice, but many other aspects of Arctic marine ecosystems are being profoundly altered. The impacts of these changing environmental conditions on marine mammals may be exacerbated by the rapid changes in human activity that they make possible (e.g., expansion of shipping and <a href=\"http:\/\/www.mmc.gov\/priority-topics\/offshore-energy-development-and-marine-mammals\/\">offshore energy exploration<\/a>,\u00a0mining, commercial fishing, coastal development and tourism).<\/p>\n<figure class=\"graphic alignright\" data-modal=\"photo\"><img loading=\"lazy\" class=\"wp-image-2674 size-large\" src=\"http:\/\/www.mmc.gov\/wp-content\/uploads\/5103118034_47489ff5fe_o-1024x681.jpg\" alt=\"Scientist on ice flow listening for real-time sounds of marine mammals and other marine fauna.\" width=\"520\" height=\"346\" srcset=\"https:\/\/www.mmc.gov\/wp-content\/uploads\/5103118034_47489ff5fe_o-1024x681.jpg 1024w, https:\/\/www.mmc.gov\/wp-content\/uploads\/5103118034_47489ff5fe_o-300x200.jpg 300w, https:\/\/www.mmc.gov\/wp-content\/uploads\/5103118034_47489ff5fe_o.jpg 1600w\" sizes=\"(max-width: 520px) 100vw, 520px\" \/><figcaption><p>Scientist listening for real-time sounds of marine mammals and other marine fauna in the Arctic Ocean, Canada Basin. (Jeremy Potter, NOAA\/OAR\/OER)<\/p><\/figcaption><\/figure>\n<p>Several species of marine mammals are <a href=\"http:\/\/www.mmc.gov\/priority-topics\/arctic\/climate-change\/\">adapted to Arctic conditions<\/a>\u00a0and are therefore bound to lose resilience as those conditions change or disappear. Further, <a href=\"http:\/\/www.mmc.gov\/co-management-and-alaska-native-tribal-consultation\/\">native communities in the Arctic depend on marine mammals for subsistence<\/a>\u00a0and cultural fulfillment. The loss of sea-ice is degrading or eliminating important habitat of marine mammals that use sea-ice and snow cover for resting, molting, hunting, reproduction, and refuge from predators (e.g., <a href=\"http:\/\/www.mmc.gov\/priority-topics\/species-of-concern\/polar-bear\/\">polar bears<\/a>,\u00a0walruses, ringed and bearded seals). The long-term consequences of climate change for other species, including bowhead and beluga whales and seasonal visitors such as gray whales and humpback whales, are less clear. However, virtually all marine mammals are likely to be affected at least indirectly by the rapid ecosystem-level changes that are underway\u2014as a result of warming temperatures, ocean acidification, longer seasons of open water, and thinner sea-ice.<\/p>\n<p>Unique among federal agencies, the Commission is also responsible for recommending provisions that ensure the availability of marine mammals for Alaska Native subsistence and cultural purposes.\u00a0 Accordingly, the Marine Mammal Commission has a longstanding commitment to <a href=\"http:\/\/www.mmc.gov\/wp-content\/uploads\/valencia_report.pdf\">support the assessment of marine mammal stocks and the management of risks to marine mammals and subsistence communities in a changing Arctic.<\/a><\/p>\n<figure class=\"graphic alignright\" data-modal=\"photo\"><img loading=\"lazy\" class=\"wp-image-2677 size-large\" src=\"http:\/\/www.mmc.gov\/wp-content\/uploads\/Ribbon-Seal-hauled-out-on-ice_NMFS_Michael-Cameron-1024x681.jpg\" alt=\"Image of ribbon seal hauled out on the ice.\" width=\"520\" height=\"346\" srcset=\"https:\/\/www.mmc.gov\/wp-content\/uploads\/Ribbon-Seal-hauled-out-on-ice_NMFS_Michael-Cameron-1024x681.jpg 1024w, https:\/\/www.mmc.gov\/wp-content\/uploads\/Ribbon-Seal-hauled-out-on-ice_NMFS_Michael-Cameron-300x200.jpg 300w, https:\/\/www.mmc.gov\/wp-content\/uploads\/Ribbon-Seal-hauled-out-on-ice_NMFS_Michael-Cameron.jpg 1600w\" sizes=\"(max-width: 520px) 100vw, 520px\" \/><figcaption><p>Ribbon seal hauled out on the ice. (Michael Cameron, NMFS)<\/p><\/figcaption><\/figure>\n<p>The opening of new sea routes across the Arctic and increased Arctic shipping is following decreased seasonal ice cover, bringing risk of oil spills as well as ship strikes and disturbance of marine mammals. Management of\u00a0<a href=\"http:\/\/www.mmc.gov\/arctic-oil-and-gas-development-and-marine-mammals\/\">offshore oil and gas development in the Arctic<\/a>,\u00a0must account for the risk of oil spills and possible energy development impacts arising from the sounds generated by seismic testing and drilling operations, possible chemical contamination, alteration of key habitats, and disturbance from vessel and aircraft support activities. It is critical to develop scientific baseline information on marine mammals and their ecosystems across the Arctic against which to assess future impacts and evaluate the effectiveness of mitigation and response efforts.\u00a0In this light, the Circumpolar Biodiversity Monitoring program under the Arctic Council\u2018s Conservation of Arctic Fauna and Flora working group published the <a href=\"https:\/\/www.arcticbiodiversity.is\/marine\">State of Arctic Marine Biodiversity Report in May 2017<\/a>, during the final Arctic Council Ministerial under the U.S. Chairmanship. This report, <a href=\"https:\/\/www.arcticbiodiversity.is\/index.php\/findings\/marine-mammals\">which was updated in 2020<\/a>, provides detailed baseline information on status and threats to Arctic marine mammals.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Arctic marine environment is changing rapidly.
