Traces of islandic volcanoes in a northeastern German lake

Precise reconstruction of regional climate changes in the past.
Traces of volcanic ash originating from islandic volcanoes have been found in the sediments of Laker Tiefer See in the Nossentiner-Schwinzer Heide natural park in Mecklenburg-Vorpommern. This allows to more precisely date climate changes of the last 11500 years. The ICLEA researchers detected traces of in total eight volcanic eruptions on Island of which six could be precisely identified. The oldest eruption occurred 11400 years ago and the youngest from AD 1875 has been also described in historical documents.

This video shows the self-combustion of freeze-dried lacustrine sediments ( dark red sediment) immediately after ventilation of the vacuum freeze dryer chamber and the movement of the combustion front (quadruple speed of the original video). Non-combusting light brown sediment bars are located nearby. Aluminium box size: 10.1 x 2.5 x 2 cm; sediment bar size: 10 x 2 x 1 cm. The smouldering and flameless combustion lased for approximately 10-20 min and reached temperatures of about 350°C. (Dräger et al. 2016).

The ICLEA session CL5.6 for Integrated climate and landscape evolution analyses: bridging long proxy data time series and instrumental observation at the European Geosciences Union EGU General Assembly 2015 in Vienna, Austria, 12 - 17 April 2015 is scheduled on:

We are pleasured to present two invited speakers:

Siim Veski (Tallinn University of Technology) will speak about Quantitative summer and winter temperature reconstructions from pollen and chironomid data in the Baltic–Belarus area (abstract EGU2015-4627).


Stefan Dreibrodt (University of Kiel) will present in his talk Integrative investigations on sediments in the Belauer See catchment (northern Germany) (abstract EGU2015-2557).

Authors explore in the study (published in journal The Holocene) how changes in land management influence pollen productivity. The authors study pollen deposition in largely annually laminated sediments from Lake Tiefer See in the Northeastern German lowlands deposited between AD 1880 and 2010. During this period, land use intensity has increased predominantly through the widespread introduction of artificial fertilizers, herbicides and heavy machinery mainly since the 1950s.

The published results are a contribution by ICLEA partners at the University Greifswald and GFZ in WP4 (Work Package Lake Sediments) in cooperation with the University of Helsinki (Finland).

Location of the 4th ICLEA international annual workshop is Słubice (18 km south of the city of Płock), Masovian Voivodeship (Poland). Venue is the Kawallo hotel in the landscape protection area Vistula valley. The Workshop is organized by the polish partner PAN with support by the ICLEA coordination at the GFZ. More information will be published in the first circular in fall 2014.

Dr. Martin Theuerkauf, Researcher in WP4 (University Greifswald) defences successful his dissertation: theme "Fine scaled vegetation patterns in the Lateglacial and Early Holocene of NE Germany - Novel GIS based approaches".

Congratulations by the ICLEA community to Dr. rer. nat. Theuerkauf!

From the 5^th to 7^th of February 2014, the second ICLEA Statistics Workshop took place in Greifswald at the institute of Landscape ecology and ecosystem dynamics, organized by Allan Buras (WP3, University Greifswald), and Markus Schwab (ICLEA Coordinator, GFZ). Altogether 16 participants separated among the WPs 3 and 4 from the Polish Academy of Sciences, the GFZ Potsdam and the University of Greifswald participated.

As in the first workshop, which took place in November 2013, the main focus of this workshop was to create a solid basis on statistical knowledge, which allows for a better analytical collaboration between the different WPs. Further methods of multiple regression, multivariate techniques and time series analyses were introduced, and applied to three different datasets (XRF-lake-sediment data, tree-ring data and Cladocera-lake-sediment data) that have been acquired within ICLEA. Furthermore first results of a multi-WP approach (including WPs 1, 2, 3, and 4) based on the SINOMA-algorithm was presented by Allan Buras.

Two new topics for joint analyses and focusing on the combination of lake sediment and tree-ring data to increase the precision of climate reconstructions were determined, of which first results are likely to be presented at the annual ICLEA meeting in March 2014.
