Dear Colleagues,

Following a very successful Third Polar Data Forum held in Helsinki, Finland in late 2019, we are pleased to announce that the Fourth Polar Data Forum will be co-hosted by the Royal Belgian institute of Natural Sciences and the European Polar Board (EPB) at the Netherlands Organisation for Scientific Research (NWO) in The Hague (NL) and online from September 20th to 24th, 2021. This event will be co-located with the Second Southern Ocean Regional Workshop for the UN Ocean Decade and Hackathon and focus on the polar oceans.  

The meeting will be co-organized with regional partners including the Southern Ocean Observing System, Standing Committee on Antarctic Data Management, the World Data System, EuroGOOS, and many other organizations engaged in polar data management.

Initial steering and organizing committees have been formed and will be expanded in the coming weeks.  If you are interested in participating, please reply directly to us.  A website with detailed information is being developed and we will notify you through this list and other channels when the site is published.  A call for abstracts will be released in mid-May, 2021 with the submission deadline in mid-June.  Notification of acceptance will be provided to authors in mid-July.

Based on previous meetings and workshops this iteration of the Polar Data Forum will combine a two  day conference style meeting (23, 24, September) in support of information exchange, with the remainder of the week using a "hackathon" approach that will build on the development work done in previous meetings and workshops (20-22, September).

Preliminary list of themes:

Knowledge mobilization and decision making

Co-production of data, information and knowledge

All aspects of interoperability

FAIR data for the polar regions

Federated Search and

Vocabularies and formal semantics

Data policy

Data management for modellers and remote sensing communities 

Data management for polar observing assets logistical information

Mapping data flows into international data aggregation efforts

Barriers to data sharing / User Requirements

Biogeochemical data management

New ships and real-time data in low connectivity locations

Kind regards,

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.
