Terrestrial Environmental Observatories

TERENO

Within the regional observatory TERENO (TERrestrial ENvironmental Observatories), the Helmholtz Association is investigating the effects of global change on terrestrial ecosystems at regional level. To this end, four regional observatories were set up for an integrated Earth observation, covering regions that are representative for Germany: Eifel/Lower Rhine Valley Observatory, Harz/Central German Lowland Observatory, Bavarian Alps/pre-Alps Observatory and Northeastern German Lowland Observatory. All four areas are equipped with combined in-situ measuring instruments as well as ground and airborne remote sensing technologies. This infrastructure project initially planned until 2025 aims to record changes in the geo-, hydro-, bio-, and lower atmosphere as well as the anthroposphere on different spatial and temporal scales. This facilitates a better understanding of the interdependencies and to develop effective prevention, mitigation and adaptation strategies in the light of global change.

Observatory Northeastern German Lowland

The observatory "TERrestrial Environmental Observatories - Northeastern German Lowland" (TERENO North-East) is operated by the GFZ. It analyses the impact of climate and land-use change on terrestrial ecosystems and currently comprises six main sites located in a region stretching from the Uckermark to the Baltic coast. TERENO North-East serves as a platform for the monitoring, analysis and prediction of changing environmental conditions.

The northeastern lowlands are one of the regions most affected by climate change in Germany. Increases of relative drought and hydrometeorological extreme events are among the greatest challenges. The TERENO observatory includes the Ucker catchment area, the Müritz National Park, the Biosphere Reserve Schorfheide-Chorin, Lake Tiefer See as well as the test site DEMMIN for calibration and validation purposes of the German Aerospace Center (DLR).

The complex relationships and feedback mechanisms of the different parts of the terrestrial systems require an interdisciplinary research approach. Important system variables, which are being monitored within TERENO, include: relocation and exchange processes of water, matter and energy in the groundwater-vegetation-atmosphere system, long-term changes in the structure and functioning of microorganisms, flora and fauna, as well as socioeconomic conditions that must be determined with sufficient temporal and spatial resolution.

The following scientific questions arise:

  • Which consequences will the expected climate change have on the groundwater, soils, vegetation and surface waters?
  • In which way will the feedbacks mechanisms affect the terrestrial fluxes of water and matter (e.g. feedbacks between land surface and atmosphere)?
  • Which direct influences have soil and landuse changes on water balance, soil fertility, biodiversity and regional climate?
  • What are the consequences of large anthropogenic interferences (e.g. open mining, deforestation) on terrestrial systems?

 

The long-term data sets developed in TERENO will significantly foster the validation, advancement and integration of terrestrial models, e.g. groundwater and soil water balance models, regional climate and weather prognostic models, air quality models, runoff and forest/agronomic models as well as diversity and socioeconomical models. Integrated model systems can comprehensively support the management of agronomic and forest ecosystems, e.g. optimization of irrigation systems as well as development of warning systems for extreme weather occurrences and flooding, integrated control systems of water management constructions, and monitoring systems for air, groundwater and surface water quality.

Data management

The working groups in TERENO North-East are supported during the processes of collecting, providing, integrating, managing and exchanging of heterogeneous digital resources. Data Management controls data storage and secures internal and external data access via standardized exchange formats and, thus, data provision in the central TERENO Data Discovery Portal TEODOOR.

Geoarchives

Complex data on climate and landscape development are collected. These are combined in order to derive improved predictions for the future. For this purpose, lake sediments and tree year rings, in particular, are analyzed; in addition samples of archaeological and fossil wood material as well as paleosoils are examined.

Remote sensing

In the DEMMIN test field data on vegetation, soil and exchange processes between soil and atmosphere are recorded. The terrestrial data are compared with aircraft and satellite-based information from remote sensing. These algorithms can finally be transferred to areas for which there are remote sensing data, but only a few terrestrial data available. This facilitates to efficiently gain regional insights into environmental conditions.

Geomicrobiology

Probenahme im Klockenbruch, Serrahner Teil des Müritz Nationalparks

As part of the Helmholtz Young Investigators GroupMicroCenethe working group geomicrobiology deals with the microbial carbon cycle of peat bogs. Molecular methods are used to identify, quantify and characterize key organisms of the methane cycle of various types of peat bogs. The working group thus contributes to the process understanding of current trace gas flows and creates the basis for interpreting the spread and activity of microbial communities in cores of peat bogs reaching back thousands of years. The aim of the work is to be able to better estimate the influence of microbial communities on the trace gas fluxes in the course of the natural and anthropogenic origin of peat bogs. Study sites are the near-natural, oligo- and mesotrophic kettle moors of the Müritz National Park, the coastal peat bog Hütelmoor as well as the eutrophic polder Zarnekow.

Geopedology

The main focus of the soil monitoring is the observation, impact analysis and forecast of soil relocation and coupled material flows in the landscape. The work will be carried out in close cooperation with the Leibniz Center for Agricultural Landscape Research (ZALF) Müncheberg. The main study regions are the intensively agriculturally used Ucker catchment, in particular the Quillow catchment area near Dedelow. Here, a lysimeter is operated as part of the SoilCan project. Each SoilCan-Lysimeter is equipped with sensors facilitating the acquisition of balance parameters such as leachate, soil moisture, evapotranspiration and precipitation with a high temporal resolution. In addition, for the analysis of historical soil relocations and pedogenesis, the catchment area of the Großer Fürstenseer See in the Müritz National Park is another focus region.

Hydrology

In the Great Lake Fürstensee and in its catchment area (Müritz National Park), the dynamics of water and matter moving between running water, sediment and groundwater are examined in detail. In addition, measuring stations are operated at various water gauges in order to monitor the water quality over an extended period of time. In summary, the landscape water balance in the region can be comprehensively stated.

Helmholtz Young Investigators Group TEAM (Trace Gas Exchange in the Earth–Atmosphere System on Multiple Scales)

Exchange processes between terrestrial systems and the atmosphere are investigated on different temporal and spatial scales. The aim is to improve the understanding of the biological, chemical and physical processes that control the exchange of energy and greenhouse gases between soil, vegetation and atmosphere. The determination of the gas fluxes between the ecosystem and the atmosphere takes place in a rewetted peat bog of the Peene near Zarnekow / Dargun using the so-called eddy covariance method. This micrometeorological method is used both at eddy-towers, as well as by means of helicopter or aircraft rides, in order to examine areas of different sizes.
