Stack plot of the 12 most abundant species comprising ~85% of the ostracode assemblage in a narrow band of the Alaskan Beaufort Sea (sites on Fig 4 map) within 100 km of shore at 20-90m water depth from years 1971 to 2018, (n = 55 surface sediment samples with ≥30 specimens/sample, 6,617 total specimens). Samples collected in 2018 are highlighted in yellow. Other species not shown on the stack plot that account for 1–2% of the assemblage include Rabilimis septentrionalis , Pteroloxa chaunensis , E . concinna , and several Cytheropteron species. Important species in the Bering and Chukchi that exhibited either very low abundance (<1%) or are absent in the Beaufort Sea at 20-90m water depth are: S . ikeyai ., M . mananensis , Finmarchinella spp ., K . arctoborealis , H . clathrata , H . emarginata , J . acuminata , S . affinis , S . mainensis , and S . undata .
