Dear Colleagues:
During the Third Polar Data Forum (PDF) held in Helsinki in November of 2019, members of the Polar Data Community gathered to share information and knowledge and to make practical progress towards greater data sharing and interoperability.  PDF III followed on a series of meetings that have resulted in continuing advancements in the areas of federated search, identification and development of shared vocabularies and formal semantics, data policy, community building and other topics.  Since PDF III, the dialogue has continued. In March and early April, the Arctic data community met during the online Arctic Observing Summit (  The Standing Committee on Arctic Data Management (SCADM) and members of the Southern Ocean Observing System (SOOS) Program have met meeting regularly.  There is broad agreement between these groups and the IASC-SAON Arctic Data Committee (ADC) that meeting more frequently will help us to continue making practical progress on our shared goals.
During these challenging times, meeting in person is not feasible.  However, recent online events have demonstrated that we can successfully collaborate using virtual tools.  
We would like to invite you to join us online on June 30th from 14:00 - 17:00 UTC to continue our efforts to enhance polar data sharing and interoperability.  This will be the first of a planned bi-monthly series of online workshops convened by the ADC, SCADM, SOOS, the Arctic Observing Summit Working Group 4, the Global Cryosphere Watch, and the World Data System on behalf of the polar data community. 
A detailed agenda, objectives and a registration link will be shared in the coming days/weeks.  The general draft agenda is as follows:
1.  Meeting kickoff (plenary) (30 minutes):  Overview of recent developments and objectives for the meeting.

Note:  Due to mutual interests, Working Groups 1 & 2 will start the meeting together to discuss common interests (e.g. metadata vocabularies).  If desired, groups will separate.

Working Sessions (2.5 hours)

2.  Breakout Working Group 1:  Federated Search.  Hosted by POLDER (
•  Share developments in the area of  metadata aggregation with particular focus on

  •  Discussion of linking schema.orgto other metadata standards and services (e.g. ISO 19115/ OGC CSW)
    •  Identify key shared metadata vocabularies in use

3.  Breakout Working Group 2:  Vocabularies and Semantics. Hosted by the ADC-IARPC-SCADM Vocabularies and Semantics Working Group (
• Determine how to work on the Best Practices part of science on
• Work on Time, space, and other sections of science On not addressed at PDF III

  • Understanding the process for contributing to community ontologies (e.g. ENVO)
    4.  Breakout Working Group 3: Policy.  Hosted by SCADM, SOOS and the Arctic Data Committee (Stein Tronstad lead):  At the third Polar Data Forum a process was initiated to update and align the data policies of IASC, SCAR, SOOS and potentially other polar science groups. We aim to move this process forward by forming a bipolar group to work on objectives andcore principles of an updated, «bipolar» data policy document. During this initial webinar we will also be looking at the rationales and key principles of some important international data policies.
    This discussion will also engage representatives from the global data community to ensure broad interoperability.

It is with great anticipation that we officially announce that our upcoming Arctic Change 2020 conference will be coming to you as a Virtual Event from 7-10 December 2020! Whether you are a seasoned ArcticNet conference participant or plan on joining the event for the first time this December, be assured that AC2020 will deliver the quality we have all come to expect from the Network’s annual conferences over the past decade albeit in a new format. We regret that greeting you in person is not possible, however, this challenge has opened exciting and innovative avenues which will maximize engagement and make it easier than ever before to tune in! Distance is no longer an obstacle and we are delighted that a wider audience can be a part of what has become the largest Arctic science event in North America.

Planning is well underway and we will be communicating with you later this summer with further details on how this virtual format will come to life. We look forward to launching the Call for Abstracts mid-July and to receiving your submissions.

Kind regards,

AC2020 Organizing Committee

The webinar called “Stronger together”: European cooperation for Polar science and society - The Integrated European Polar Research Programme will take place on 11th June 2020, 10:00 – 13:00 CEST by a Zoom videoconference.

The agenda for the EU-PolarNet Webinar on the European Polar Research Programme is now available on the EU-PolarNet website:
