Sampling during the ice experiment

The sunny sky greatly improved the sampling campaign which took place today. It is part of the ice experiment currently running at the LakeLab. Before the scientists were able to determine water transparency with the secchi disk and to collect ice, water and plankton samples, holes had to be cut into the ice. ... [»]

At last winter at Lake Stechlin

The IGB team around project manager Dr. Stella Berger has been waiting quite a while for these cold temperatures. The scientists were ready to start the scheduled ice experiment at the LakeLab. Now their time has come: Ice forms on Lake Stechlin as well as in the enclosures of the LakeLab. Since ice cover duration of lakes is modified due to climate change, the scientists want to explore the consequences of such ice cover shifts for lake ecosystems. ... [»]

Aquacosm: First call for Transnational Access in 2018 is now open

Between January 2018 and December 2020 the EU financed project AQUACOSM — Network of Leading European AQUAtic MesoCOSM Facilities will offer more than 11500 person-days of Transnational Access to more than 37 different European mesocosm facilities ranging from the Sub-Arctic to the Mediterranean and beyond, from mountains to lowlands, from freshwater to estuarine and fully marine systems, and spanning from ultra-oligotrophic to hyper-eutrophic conditions. The IGB LakeLab located in Lake Stechlin is one of the supported research facilities. ... [»]

Organized by young researchers for young researchers

Every two years, the scientific meeting "Fresh Blood for Fresh Water" appealing exclusively to young aquatic ecologists, is organized by a different research institute or university. This year, the Biological Center of the Czech Academy of Sciences in Budweis hosted the conference from April 9th to 13th. Nearly 60 researchers –master and PhD students as well as young postdoctoral fellows – from many European countries took part. Among those also the two LakeLab researchers Susanne Stephan and Cleo Stratmann. ... [»]

Consequences of extreme summer storm tested in IGB LakeLab: Turbid prospects for pristine lakes

The frequency of extreme weather events is increasing due to climate change. This includes summer storms, which will disturb terrestrial and aquatic ecosystems more often in the future. Two recent studies by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB), published in the renowned journals "Ecosystems" and "Global Change Biology", now show that such storms can have dramatic effects on ecosystem processes, especially in pristine lakes where they can cause massive algal blooms. ...

From Arctic to the Mediterranean

Lakes, rivers, estuaries and oceans are closely connected. Despite this, aquatic research is still divided in marine and freshwater sciences. Now scientists from 19 leading research institutes and universities and two enterprises from 12 countries across Europe aim to change this and have joined forces in the project “AQUACOSM - Network of Leading European AQUAtic MesoCOSM Facilities Connecting Mountains to Oceans from the Arctic to the Mediterranean”. The network will perform the first systematic large-scale experiments in both freshwater and marine ecosystems. The project is coordinated and lead by Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB). ... [»]

From Costa del Sol to Lake Stechlin

In addition to German and English, Spanish is the most frequently used language at the LakeLab this year. Six Spanish guests, including Professor Maria Segovia Azcorra and her two doctoral students Charo Lorenzo Garrido and Victor Vazquez Manzanares from the University of Malaga, take part in this year's LakeLab experiment on the effects of light pollution. Their special research field is the stress physiology of phytoplankton in marine systems however this summer the three "Málagueños" exchanged the Mediterranean Sea against Lake Stechlin. ... [»]

Who invented it?

With chocolate, Lucerne Birewegge* and a self-developed respiration system in his luggage, Dany Steiner, technician at the Swiss Federal Institute of Aquatic Science and Technology – Eawag, arrived at Lake Stechlin. His main objectives: To break out from the usual work routine and get insights into the operation of another research institute and at the same time to implement his technique of respiration measurements at IGB Stechlin. By the end of August, he was successfully involved for three weeks with the LakeLab experiment on light pollution before he returned with many new impressions to Lake Lucerne. ... [»]

At night all researchers are grey

Throughout the LakeLab experiment 2016 samples are regularly taken during day and night. For example, the team of IGB scientist Gabriel Singer gets out once a week shortly before dawn. They focus on aquatic bacteria which are responsible for the decomposition of organic material. ... [»]

Searching the darkness – Impact of light pollution is tested at one of Germany’s darkest regions

Nights which are almost as dark as before the introduction of the electric lighting system can still be experienced at Lake Stechlin in the north of Brandenburg. This message is the result of a study recently published by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB). Not only hobby astronomers but also the scientists will benefit from these good conditions. They will examine the impact of increasing light pollution on lakes and aquatic organisms at the IGB LakeLab, a floating research platform in Lake Stechlin. The experiment that starts today focuses on skyglow. ... [»]

Fish released into the LakeLab

In this year's LakeLab experiment, PhD student Franziska Kupprat studies how fish respond to light pollution. As an important member in the food web of lakes these animals may not lack in the enclosures. However, but it must be assured that the enclosures contain the same number and weight class of fish. Therefore eight European perches have been released today into each of the 15 participating enclosures. ... [»]

The Stechlin swing

No, we are not talking about a new technology for skiing or dancing. With the Stechlin Swing algal growth on the enclosure walls should be decreased. It is composed of large plastic sheets of 8 x 8 meters in size, which cover the inner walls of the enclosures. Last week, 60 Stechlin Swings were constructed and installed. ... [»]

Illumination lake ecosystems

The start of this year's LakeLab experiment is getting closer. For the preparations the team is working full tilt. The project "Illumination lake ecosystems – ILES" aims at elucidating how light pollution affects lakes and aquatic organisms. It focuses on the diffuse illumination of the night sky caused by artificial light, the so-called skyglow. For the experiments, physicist Andreas Jechow and his team developed a special lighting system. Two rings that are equipped with LED lights will be installed in 15 of the 24 enclosures in order to simulate skyglow. At Lake Stechlinsee the effects of light pollution can be particularly well explored, since this is one of the darkest places in Germany and thus offers excellent reference conditions. ... [»]

Laboratories of the future

Already in the beginning of August, «Stern» journalist Rüdiger Braun visited the LakeLab. Today his article appeared in the journal «Stern». On the occasion of the UN conference on climate change in Paris, the paper presents innovative field laboratories such as the LakeLab in Lake Stechlin, the marin mesocosms from Kiel and the Kranzberberg forest roof experiment where scientists simulate future environmental conditions expected with proceeding climate change. ...

"As a light physicist I have until now mostly worked in darkened and sterile laboratories"

After returning from his postdoctoral residency at the University of Brisbane in Australia, Andreas Jechow visited by chance the Lake Stechlin Information Center in 2012. There he saw a scale model of the LakeLab and was immediately fascinated by the research platform and the concept behind it. Now, three years later he is part of the LakeLab team and studies the light regimes in the mesocosms. ... [»]
