DESCRIPTION:Taking its name from the Iñupiaq phrase for “ice bridge” 
 the Ikaaġvik Sikukun project has successfully built bridges between a div
 erse team of scientists and Indigenous Knowledge-holders to study the chan
 ging sea-ice environment of Kotzebue Sound\, Alaska. We have broken new gr
 ound by co-producing our hypotheses in partnership with an Indigenous Elde
 r advisory council to develop research questions that cut across disciplin
 ary boundaries and address the needs of both the local and scientific comm
 unities. To share our story broadly and in a way that respects the oral tr
 aditions of Indigenous Knowledge\, our team also includes an ethnographic 
 film-maker who has been documenting each step of our unique research journ
 ey. Over the past three years\, with continued guidance from our advisory 
 council\, we have designed and carried out a research plan to observe the 
 sea ice and marine mammals in Kotzebue Sound and how these come together a
 s habitat and hunting grounds. Using satellite data\, unmanned aerial syst
 ems (UAS)\, oceanographic moorings and on-ice measurements we have witness
 ed two exceptional years (2018 and 2019) with unprecedentedly low sea ice 
 extent and the earliest start of bearded seal (Erignathus barbatus) huntin
 g in recent memory – contributing to a broader trend towards shorter spr
 ing hunting seasons\, which have been recorded in Kotzebue since 2003. We 
 also observed widespread flooding of the landfast ice\, possibly caused by
  relatively high snowfall on top of thin ice\, as well as the detachment a
 nd fragmentation of landfast ice recently occupied by ringed seal (Phoca h
 ispida) pups\, adults\, and their lairs. Having integrated Indigenous Know
 ledge throughout our approach\, we are now in a unique position to turn th
 ese interrelated observations into answers to our research questions. Join
  the diverse Ikaaġvik Sikukun team as I share an overview of our research
  approach and preliminary results including observations of the sea ice he
 at budget that undergoes a rapid change during Spring melt and breakup\, a
 s well as the profound impact of sea ice change on the traditional use of 
 these regions by local indigenous Iñupiaq populations.\n\nTeam: Andrew R.
