• Is the poleward expansion by Atlantic cod and haddock threatening native polar cod, Boreogadus saida? (2011, background): “In the best-documented study of polar cod densities under the ice, concentrations were quite low (never seen during seven 30 m video transects), and usually found singly or in small groups in cracks between ice layers (Gradinger and Bluhm 2004).”
• Linking mercury exposure to habitat and feeding behaviour in Beaufort Sea beluga whales (2008, unknown): “We paired the beluga feeding groups with hypothetical, habitat-specific food webs according to their spatial segregation, i.e.: 1) beluga using shallow, open-water habitats likely use the Mackenzie Delta extensively and were therefore paired with the estuarine-shelf food web; 2) beluga selecting the”
• Under-ice distribution of polar cod Boreogadus saida in the central Arctic Ocean and their association with sea-ice habitat properties (2014, methodology): “…studies, mainly pelagic and demersal trawls were used in open water areas (Ponomarenko 2000; Matley et al. 2013; Nahrgang et al. 2014), while under-ice abundance estimates were made based on hand net sampling (Melnikov and Chernova 2013) and observations by divers (Gradinger and Bluhm 2004).”
• The importance of ice algae‐produced carbon in the central Arctic Ocean ecosystem: Food web relationships revealed by lipid and stable isotope analyses (2016, background): “Together with O. glacialis and G. wilkitzkii, A. glacialis is known to live permanently associated with the Arctic sea ice (Poltermann 2001; Gradinger and Bluhm 2004).”
• From polar night to midnight sun: photoperiod, seal predation, and the diel vertical migrations of polar cod (Boreogadus saida) under landfast ice in the Arctic Ocean (2010, background): “…the adults are dispersed in habitats ranging from coastal brackish waters to the demersal and pelagic zones of the shallow shelves, including the ice–water interface and the ice pack itself (e.g., Craig et al. 1982; Lønne and Gulliksen 1989; Jarvela and Thorsteinson 1999; Gradinger and Bluhm 2004).”
• The sub-ice algal community in the Chukchi sea: large- and small-scale patterns of abundance based on images from a remotely operated vehicle (2005, methodology): “Remote methods of observing sub-ice communities have proven successful in the Arctic (Alexander 1980; Gutt 1995; Werner and Lindemann 1997; Gradinger and Bluhm 2004 ) and Antarctic (Brierley and Thomas 2002) at revealing patterns of ice algal distribution and abundance.”
• Segregation of Beaufort Sea beluga whales during the open-water season (2006, unknown): “If habitats are selected for feeding, then belugas could be feeding on Arctic cod (Boreogadus saida (Lepechin, 1774)) under the ice (Gradinger and Bluhm 2004), or they may be feeding on the rich benthic food available from the deep-water environment.”
• Characteristics of meiofauna in extreme marine ecosystems: a review (2018, background): “To avoid salt stress, amphipods can swim and select more suitable depth and ice structures (Gradinger and Bluhm 2004).”
• Vertical segregation of age-0 and age-1+ polar cod (Boreogadus saida) over the annual cycle in the Canadian Beaufort Sea (2016, background): “Several studies have documented the presence of polar cod\2 years of age in sea ice anfractuosities, indicating that some individuals are sympagic early in the life cycle (e.g. Lønne and Gulliksen 1989; Gradinger and Bluhm 2004; Melnikov and Chernova 2013).”
• The aggregation of polar cod (Boreogadus saida) in the deep Atlantic layer of ice-covered Amundsen Gulf (Beaufort Sea) in winter (2011, background): “Sea ice, light, and the winter aggregation of polar cod Several studies have shown a strong association between polar cod aggregations and sea ice (e.g. Bradstreet et al. 1986; Lønne and Gulliksen 1989; Gradinger and Bluhm 2004).”
