Dear subscriber,

It's been a litte longer than we anticipated, and we are excited to share some updates with you.

First, the LinkedEarth team would like to thank all the participants of the Workshop on Paleoclimate Data Standards, that was held in Boulder last June, which was a resounding sucess from our point of view.

The workshop generated interesting discussions and we are currently working on implementing some of the recommendations. To learn more about the outcomes of the workshop, please read the report in the latest issue of the PAGES magazine.

What's next for LinkedEarth?


It took us much of the summer to update the ontology to include broader concepts of paleoclimatology. The biggest change is that the LinkedEarth ontology is now mostly a data model, and is linked together with other ontologies that you (yes, you) have the power to edit and expand. To learn how, please visit this page. The ontology also re-uses many concepts from other ontologies, which means that it will be useful to a wider community.

Big ups to Daniel Garijo and Deborah Khider for getting it done. The ontology is a solid foundation to assimilate and generate knowledge in our field, and we are excited to see it grow as more of our colleagues used the platform to describe and analyze their data.



Varun Ratnakar has made great strides updating the wiki:

It is now fullly linked to the new ontology; social profiles allow each member to describe themselves better and to keep track of everyone's volunteer time (brag about it to your program manager). You can also join working groups; to contribute to the data standard. Finally, we are working on user-friendliness (now featuring a button to download the datasets you care about).

We revised the design of the front page to make it easier to access the information that you want.

We also created a step-by-step tutorial for new and more experienced wiki users.

In the next months, we plan to:

1. Allow for intuitive queries.

2. Build a data/metadata importer directly on the wiki.

3. Share scientific workflows that use the wiki.

If you have further suggestions on user experience, please address them to


We are also slowly building the database. You might have noticed that it only contains a few coral records, mostly from the Ocean2k compilation.

In the next few months, we will add:

1. ~600 more records from the PAGES2k database

2. ~100 marine Holocene records

3. 182 benthic stable oxygen isotope records covering the past 5 million years

This, of course, is in addition to the records you might upload. Please hold off on that, however, we are still working out some kinks. Please look for details in the next newsletter.

How can you help?

We are looking for volunteers to:

  1. Create/join working groups to develop data standards for each archive. 
  2. Coordinate such working groups
  3. Join the Ontology Editorial Board. To learn more about the duties of  Editorial Board members, read our charter and the editorial process.
