Outreach

Meet QUEST at EGU 2018

With the EGU General Assembly coming up next month, we have rounded up the first-author presentations from the people involved in QUEST. Most of the action takes place during Thursday and Friday (barring David Hodell’s presentation on Tuesday) and in Hall X5 and Room F2. Be sure to note this down in your calendar for the EGU week!

The topics are many, interesting, and diverse — they are sure to spark off interesting discussions and debate. Share this post with your colleagues and spread the word!

Workshop on palaeoclimate time series analysis and statistics in Potsdam

Last week, representatives of all QUEST collaborators met on the Telegrafenberg in Potsdam for the QUEST Workshop on palaeoclimate time series analysis and statistics to disseminate our results, first among ourselves, and then to a public audience. We would like to thank all participants for their contributions and lively discussions.
The workshop was very nicely organized by Bedartha and Norbert. Beth came all the way from New Zealand, while David came from Great Britain, Inken from Mainz, and Seb and Cinthya from Bochum. We started with a short summary of ongoing work and activities in the different laboratories. An important point raised and discussed were the planned secondments (Cinthya and Inken had aleady packed for their secondments to Waikato!) and under which conditions Thomas can actively participate to QUEST. We then got quick updates from the different laboratories, all make good progress with respect to quantification of proxy data. A cosy workshop dinner in Old Town Potsdam facilitated more discussions of ideas and thoughts.
On Thursday and Friday we had several lectures and hand-on sessions, open to the public. Colleagues from as far as Australia learned about agemodeling, recurrence analysis and other innovative statistical tools developed at PIK Potsdam. Hands-on sessions gave the opportunity to discuss the complexities of unpublished data and the subtilities hidden inside the obvious.
The workshop also served as a platform to strike new collaborations and to exchange ideas how to extract a wealth of information from multi-proxy data.
The next workshop will take us to the Antipodes.

Public outreach at the 20th anniversary of the Speleo Club Berlin

The Speleo Club Berlin is a small caving club of cavers from Germany’s capital and surrounding region. At the 20th anniversary of this club in the assembly hall of the “Radfahrer-Kirche” in Kienitz at September 23rd 2017, Norbert gave a public talk on several scientific aspects of cave research, including speleothem based palaeoclimate studies as performed within QUEST. The audience, consisting not only of speleologists but also of the curious public, has been very interested and enquiring.

QUEST in the Arctic

Norbert contributed to the Sydney Chapman Chair Seminar series “Complex Systems Science Meets Arctic Science” at the University of Fairbanks, Alaska, 28 Feb 2017 and 2 March 2017: One lecture on recurrence plot analyses for the scienific experts and one lecture on “Caves as scientific archives” for the non-expert audience, but both related to research performed within QUEST.

There was opportunity to visit the one and only permafrost tunnel of the world.
