Thrilled to be part of this important study led by Dr. Goodman. Key takeaway? Climate change is transforming the Bering Sea, shifting species distributions northward and reshaping populations as warming intensifies—novel conditions will reshape much of the Bering Sea by century’s end. bit.ly/3P0U1dd
Hindcasted (1995–2015) summer log biomass density and projected end of century (2080–2099) change in log biomass density under low warming or "SSP 1–2.6" and high warming or "SSP5-8.5" scenarios. Scales for biomass density and change in biomass density differ among species and life stages to allow for intercomparison of spatial patterns. Inset: Map of the EBS survey region, showing NBS and SEBS sub-regions and corresponding stations on the standard survey grid. Maps of two metrics of environmental novelty in the Bering Sea survey region for average temperature, pH and oxygen conditions during 2040–2059 and 2080–2099, under each climate scenario (low warming or "SSP 1–2.6" & high warming "SSP 5–8.5") and each climate model (CESM, GFDL & MIROC). Areas in grey are those for which temperature, pH and oxygen are within the range of the average hindcasted conditions between 1995 and 2015. Areas in red/orange are those for which temperature, pH and/or oxygen lie completely outside of the set of average conditions observed between 1995 and 2015. Areas in blue/green are those for which temperature, pH and oxygen lie inside the range of hindcasted conditions, but represent novel combinations of these covariates. For both metrics, brighter colours indicate more novel conditions.
