ACME scientific goals

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)

2020–2021: Database building.

Winter 2022: Second ACME workshop, targeted particularly at early-career researchers.

Summer 2022: Third ACME workshop prior to, and special session at, PAGES Open Science Meeting.

2022–2023: Planning of ACME 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.
