First estimate of CS subpopulation size

Data collection from field studies that ended in 2016 have provided the first rigorous estimate of demography and abundance of the Chukchi Sea subpopulation, and indices of subpopulation status are generally positive. In a recently published paper in Scientific Reports, the authors stated that:  "Abundance of the Chukchi Sea subpopulation, derived by extrapolating density from the study area using a spatially-explicit habitat metric, was 2,937 bears (95% CRI = 1,552–5,944). Our findings are consistent with other lines of evidence suggesting the Chukchi Sea subpopulation has been productive in recent years, although it is uncertain how long this will continue given sea-ice loss due to climate change".
