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. ...

Participants of the DIPCON conference visit the LakeLab

Today, IGB scientists Mark Gessner, Ute Mischke and Peter Casper welcomed 16 participants of the DIPCON conference at the LakeLab. The excursion was part of the 17th International Conference of the International Water Association (IWA) on Diffuse Pollution and Eutrophication. The meeting jointly organized by IWA and IGB took place in Berlin from 13th to 18th of September.


"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. ... [»]


"I have chosen this PhD project because I find it amazingly interesting"

After her master's thesis on zooplankton, biologist Susanne Stephan wanted to broaden her knowledge and did not hesitate to accept the proposed PhD position on phytoplankton at the LakeLab. Now after almost 3 months at IGB Stechlin, she is already in the thick of it, and has learned a lot of new techniques. Furthermore, she enjoys working with the highly motivated LakeLab team. ...

High school interns on the LakeLab

Three students from the tenth grade in Strittmatter High School in Gransee are currently completing their two-week socio-ecological internship at the LakeLab. While accompanying the scientists of IGB Stechlin they get insights into a variety of tasks and the ongoing research conducted there. ... [»]


«It is very rewarding to be part of a large team with a common goal!»

«Compared to last year when we worked with only 8 enclosures, this year we are running an ambitious experiment using 21 enclosures», says Darren Giling, Postdoctoral fellow at IGB Stechlin. Together with more than 60 people taking part in the LakeLab experiment 2015, he is one of the mainstays always giving a helping hand or sharing his experience with new people in the LakeLab team. ...

Prof. Georg Pohnert from the University of Jena visits the LakeLab

Phytoplankton communication is the main research interest of Prof. Georg Pohnert from the Institute for Inorganic and Analytical Chemistry of the University of Jena. So far he focused on marine algae. Now Pohnert visited IGB Stechlin in order to discuss future collaborations within the scope of possible research projects at the LakeLab. Dr. Jens Nejstgaard, Scientific Coordinator of the LakeLab, took him on a tour to the platform. ... [»]


The LakeLab in the rbb TV series "A summer in Brandenburg"

During last summer, from June to September 2014, rbb journalist Johannes Unger and his team travelled through Brandenburg. Driving an old Robur bus that had been produced in the former GDR, they were looking for exceptional places, people and stories. On July 22nd, they stopped over at IGB Stechlin where Prof. Hans-Peter Grossart and PhD student Thomas Hornick explained their research at the LakeLab. The whole trip has been summarized in a special road movie that will be broadcasted in four parts at the rbb TV from April 28 to May 1, 2015. ... [»]


"You can be proud of this facility"

Today, Professor Ulf Riebesell of the Helmholtz Centre for Ocean Research in Kiel (GEOMAR) visited the LakeLab. Using marine mesocosms, he investigates how oceans and their organisms respond to acidification and global warming.
