2nd September 13:00-15:30 UTC


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 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 2nd September 13:00 - 15:30 UTC to continue our efforts to enhance polar data sharing and interoperability.  This is an online workshop in a planned series of bi-monthly 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.

Due to the constraints of our virtual platform, participation is limited. Registration is required. Connection information for the virtual meeting will be provided to registered participants closer to the event time.

Draft agenda:
1.  Meeting kickoff (plenary) (5 minutes): Introductory remarks, overview of recent developments and objectives for the meeting series can be found in the documentation from the first workshop on 30th June 2020. An introduction to the workshop is found as this recording by Peter Pulsifer from the first workshop on 30th June 2020.
2. Working Sessions (2.5 hours)

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.


Breakout Working Group 1: Federated Search. Hosted by POLDER (
& Breakout Working Group 2: Vocabularies and Semantics. Hosted by the ADC-IARPC-SCADM Vocabularies and Semantics Working Group (

NB: POLDER has a new GitHub Repo so that we can keep track of changes to our template example and start putting things into a best practice document. Join us!

13:05-13:35 : Demonstration of a thematic portal for Arctic repositories using the new DataONE Plus service, by Matt Jones. Followed by discussion.
There are roughly 100,000 Arctic-ish (> 50 degrees North) datasets in 26 repositories that are currently in DataONE, including many that are on the matrix worksheet from POLDER. Matt and his team have been harvesting from some of those, and other metadata records from others. It would also be interesting to see if more repositories were ready with published records to be harvested. Here's a summary of the current content -- Pangaea has the most datasets, as can be seen in the graph. The DataONE Plus service also provides a set of metadata completeness metrics following the FAIR principles that I think would be of interest. We could create a similar portal for Antarctic data, or a combined Arctic and Antarctic portal if that makes sense, as well as thematic clusters of data.

13:35-14:20 : Describing the contents of a dataset

Continue discussions on how best to describe 

  • less structured data types, such as interviews, and 
  • derived variables, such as remote sensing products and model outputs, 
  • Structured datasets without relevant controlled vocabularies

In preparation, please follow the three links in this comment on the ESIP GitHub page to catch up on a parallel discussion in the earth sciences community. It is unlikely that we will resolve these issues today so the conversation will likely focus on a process for resolving them (perhaps a small group discussion?) 

If there is time, some discussion on what level of granularity we want to be able to describe datasets at. 

14:20 - 14:30 Tea Break

14:30 - 15:10 Time, Space, and Licencing

Tidying up our recommendations on documenting 

  • time (including gaps in time and geological time), 
  • space, and 
  • licensing.

Through this discussion, we will update the template created in Helsinki.

15:10 - 15:30 Best Practice Documentation

What do we want to include in a best practice guide for implementing Can we create a skeleton structure for a document so that we can work on it between meetings?


Breakout Working Group 3: Policy. Hosted by SCADM, SOOS and the Arctic Data Committee (Stein Tronstad, lead)

  • 13:05-14:10

    During this session we will aim to develop an outline for a “Polar Data Policy Recommendations” document, based on our discussions during the June 30 workshop. The intended purpose of such a document will be to identify the most important concerns (rationales) for polar data policies to address, to identify needs for alignment between the existing polar data policies, and to provide recommendations on the core data management principles that should be laid down by future revised data policies.

    Our ambition is to have a complete document ready by the end of this year, as an input to further discussions within the interested communities (SCADM, ADC, SOOS and others). Everyone interested is welcome to contribute.

    The outcomes of the June 30 data policy session can be found here.

    As a starting point for discussions an initial document outline can be found here.
