The Arctic cryosphere is changing rapidly due to increased runoff from land, changing sea-ice regime and the degradation of the circumpolar permafrost zone. Fjords and other nearshore areas form a productive zone that is vital for both Arctic biodiversity and local communities, rendering the understanding of Arctic coastal ecosystem change from a long-term perspective crucial.
The Past Global Changes (PAGES) working group project ACME provides a community platform to critically assess and refine available coastal marine proxies that can be used to reconstruct cryosphere changes and their multifaceted ecosystem impacts. ACME seeks to promote a leap forward in the accuracy of paleo reconstructions that are central for deciphering cryosphere-biosphere interactions in the Arctic region at relevant timescales.
