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 The oldest eruption occurred 11400 years ago and the youngest from AD 1875 has been also described in historical documents.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).

New paper published

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).  

Save the date: 23 - 26 June 2015
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.

Drilling at the Biesenthaler Becken

German-Polish joint drilling action at the Biesenthal Basin (NE Brandenburg). From the 1st to 2nd of July 2014 the ICLEA partners PAN and GFZ as well as the cooperation partner Landesamt für Bergbau, Geologie und Rohstoffe Brandenburg (LBGR) drilled sediments of a palaeo-lake at the Wukenfurche between the lakes Großer and Kleiner Wukensee. The estimated sediment ages are late Glacial to early Holocene time. Aim of the investigations in work package WP4 (lake sediment data) are new insights in the regional climate and landscape development since the last ice age in a highest temporal resolution.

Probenentnahme am Tiefen See

The EGU General Assembly 2014 in Vienna, Austria, 27 April – 02 May, will bring together around 10.000 geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geosciences.
This year ICLEA is organizing the session CL6.1 "Integrated climate and landscape evolution analyses: bridging long proxy data time series and instrumental observation". New ICLEA results and to our research related results about the theme will be presented and discussed in six talks and at 25 posters.

Probenentnahme am Tiefen See

Thursday March 13, 2014

A public colloquium about ICLEA acivities at the Lake Tiefer See region will be held at the information Centre of the Nature Park Nossentiner/Schwinzer Heide “Karower Meiler”.
The colloquium language will be German.
For registration contact the Nature Park.

The Nossentiner/Schwinzer Heath Nature Park (German: Naturpark Nossentiner/Schwinzer Heide) lies in the western part of the Mecklenburg Lake District in the north German state of Mecklenburg-Vorpommern. The total area of the nature park is 365 km² of which 60% is wooded, about 14% consists of rivers and lakes and the remainder is cultural landscape. There are almost 60 lakes in the nature park. Special features of the nature park are the sandar - sand and gravel deposits left by the last ice age.

2nd ICLEA Statistics Workshop

Participants at the 2nd ICLEA statistics workshop
Fotos: A. Buras, UG

From the 5th to 7th 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.

 

Succesful First ICLEA Statistics Workshop

From the 6th to 8th of November 2013, the first ICLEA Statistics Workshop took place in Greifswald. Organized by Allan Buras (WP3, University Greifswald), Elisabeth Dietze (WP4/5, GFZ Potsdam) and Markus Schwab (coordination), the workshop took place in the seminar room of the Alfried-Krupp-Wissenschaftskolleg. 21 ICLEA members of the WPs 1, 3, 4, and 5 participated at the Workshop.

The main focus of the workshop was to create a solid basis on statistical knowledge, which allows for a better analytical collaboration between the different WPs. The workshop was very successful for qualification in statistics and the interaction between the WP participants from the Polish Academy of Sciences, BTU, GFZ and the University of Greifswald.  I.e. test-statistics, simple modeling, multivariate techniques and time series analyses were dealt with, as well as a new statistical approach (SINOMA) that has been developed within ICLEA and allows for the analysis of noisy serial data streams.
Based on the positive feedback throughout the closing session an advanced 2nd ICLEA Statistics Workshop, based on the in Greifswald acquired knowledge, will be organized for the beginning of 2014 in Greifswald. These workshops shall focus on the combination of different datasets acquired within ICLEA to synthesize the results achieved so far in interdisciplinary statistical analyses.
