TRACE 2021 is preceded by pre-conference workshops. Registration for the workshops is done via the online registration process on a first-come, first-serve basis.
Effective Scientific Presentation Workshop
Maximize the signal to noise ratio from your next talk.
Alan Crivellaro, Department of Geography, University of Cambridge
Date: 2-4 PM (CET), 1 June & 8 June
Max. participant: 12
Description: The phrase ‘giving a presentation’ strikes fear into the hearts of many and I was one of those. But presenting scientific research is an essential skill for young and experienced researchers. Therefore, I designed this workshop to guide students and scientists through what they need to know to deliver an effective presentation.
Session 1. Learn the key elements of an effective presentation.
This first session will provide information, practical exercises and plenty of opportunities for discussion. It will explore how to refine speaking style, increase personal impact and how to plan and structure an effective presentation.
Session 2. Practice your presentation and receive peer and tutor feedback.
This second session will occur a week after the first session. It aims to practice a short presentation in a supportive and friendly environment and to sharpen the skills required for an effective presentation.
Guildline: The participants will have a week in between the two session to be able to prepare their presentation, and also some days before the meeting to be able to incorporate suggestions after the second session of the workshop.
If we will have more than 15 people interested in the workshop, it can run another sessions on the 2nd and 9th of June (second group), and even on the 3rd and 10th if needed (third group).
DendroTools R package: dendroclimatological analysis using daily climate data and simple nonlinear machine learning methods
Jernej Jevšenak, Slovenian Forestry Institute, Department of Yield and Silviculture, Večna pot 2, Slovenia
Date: 10 AM (CET), 15 June
Description: This workshop is practically oriented and provides insights into the dendroTools R package, particularly emphasizing the use of daily data for dendroclimatological analysis. Short introduction about machine learning methods will be given as well, with the focus on dendroclimatic reconstructions and the comparison between different regression models. Given the advanced topic of this workshop and the comparably short time, there will be no time to explain the fundamental functioning of ‘R’ wherefore a basic understanding of ‘R’ is mandatory for a meaningful participation.
Max. number of participants: no limit
Software requirements: The newest R version
Guildline: Participants will get presentations and R codes in advance, so there should be no problem with conducting the workshop.
10.00 – 11.30 Morning session: Introduction to dendroTools R package
11.30 – 12.00 Break
12.00 – 13.30 Afternoon session: Exercises and more advanced topics
Blue Intensity for Dendroclimatology
Rob Wilson, University of St. Andrews, UK
Ryszard Kaczka, Charles University in Prague
Session A June 11th from 12pm (CET)
Session B June 14th from 12pm (CET)
Blue Intensity (BI) is as a comparable tree-ring variable to maximum latewood density (MXD) in conifer trees. MXD is the gold standard tree-ring variable for the reconstruction of past summer temperatures and research over the past decade has shown that BI performs very similarly to MXD. Measuring BI rests on the spectral properties of lignin in the cell walls which preferentially absorbs the blue part of the light spectrum. When latewood ring density is high (i.e. thick cell walls), the intensity of reflectance is low (i.e. darker). BI and MXD are therefore inversely correlated in their raw measurement forms. Unlike MXD, BI can be measured easily, quickly and cheaply from digital images of wood samples of various conifer species. Unlike MXD, it is therefore an analytical approach available to all tree-ring laboratories for a modest investment.
To date, ring-width has been the main tree-ring variable used for historical dating. However, the utilization of BI and stable isotopes provides exciting new possibilities in dendroarchaeology. The workshop will introduce both theoretical basics of the BI method and practical aspects of measuring and using it for dendrochronology with the workshop focusing on its potential for historical dating. We will however also provide participants with information relevant for utilising BI data for dendroecology and dendroclimatology.
