ACME is envisioned to run over two three-year phases.

Phase 1 (2019-2023)

ACME Phase 1 seeks to critically assess and refine current available marine proxies for reconstructing Arctic cryosphere changes and their impacts in the coastal and fjord environments of the circumpolar North.

The main goals are:

1. To build a database that contains a network of proxies commonly used for sea ice, primary production, and meltwater runoff reconstructions in Arctic coastal and fjord environments, alongside with site-specific environmental data. Each database entry will follow the criteria defined by ACME, to ensure easy data quality assessment by the data users.

2. To facilitate knowledge transfer and collaborations between proxy specialists and the integration of the field and satellite monitoring community.

3. To further critical methodological understanding and data handling skills of the next-generation of Arctic paleoceanographers and paleoenvironmental researchers.

Planned activities

2019: Collection of community ideas and perspectives.

Jan 2020: Steering group meeting.

May 2020: First ACME workshop at EGU General Assembly 3-8 May 2020, Vienna, Austria (postponed)

October 2021: First ACME workshop on criteria for the ACME database, Helsinki, Finland

2022-2023: Development of proxy-specific criteria and their application for data entry 

March 2022: Publication of “Predicting the future of coastal marine ecosystems in the rapidly changing Arctic: The potential of palaeoenvironmental records” in Anthropocene

May 2022: ACME Special Session “Cryosphere change impacts on arctic coastal environments and ecosystems during the Holocene” at the PAGES OSM Meeting

October 2022: ACME/C-SIDE PAGES Magazine Special issue

October/November 2022: 2nd ACME workshop on numerical data treatment and analysis targeted particularly at early-career researchers in Copenhagen

Dec 2022: Publication of community-refined criteria for proxy data, planned submission to Earth Science Reviews

May 2023: Third ACME workshop– main outcomes and transition into Phase 2

Phase 2

Phase 2 is envisioned to develop concrete tools that integrate the ACME Phase 1 database with field monitoring data and satellite products, and apply these into past reconstructions from the coastal zone.

The plan for Phase 2 will be elaborated during the course of Phase 1.
