The Helmholtz Climate Initiative REKLIM (Regionale Klimaänderungen/Regional climate change) is a consortium of eight research centres within the Helmholtz Association.
Theme of the Virtual Institute for Integrated Climate and Landscape Evolution Analyses ICLEA is the better understanding of the Dynamics of Climate and Landscape Evolution of Cultural Landscapes in the Northern Central European Lowlands since the Last Ice Age.
The TERENO terrestrial observatories have to be operated on a long-term basis (at least for a decade), in order to facilitate the determination and quantification of environmental changes.
INTegrating Ice core, MArine, and TErrestrial records – INTIMATE:
INTIMATE is an open network for all interested scientists working on palaeoclimate reconstructions in the period 60,000 to 8000 years ago.
Up to 460 m long sediment cores, drilled 2010/2011 in the deep basin of the Dead Sea, recover a high-resolution sequence of the Pleistocene-Holocene sedimentary record. The cores provide a record up to annual / seasonal time resolution of the palaeoenvironmental climatic, seismic and geomagnetic history of the East Mediterranean region.
Several joint expeditions by Russian, American, and German scientist mainly in 1998, 2000, and 2003 revealed that the sedimentary record of 12 km wide lake El'gygytgyn (Chukotka Peninsula, Northeast Siberia) filling a meteorite impact crater, has a high potential for a long-term paleoclimate study. Sediment cores were drilled 2008/2009 during an ICDP campaign.
PROGRESS stands for "Potsdam Research Cluster for Georisk Analysis, Environmental Change and Sustainability". It is a joint research project subsidised by the German Federal Ministry for Education and Research (BMBF) within the framework of „Advanced Research and Innovation in the New Federal States.
The joint research project CADY - Central Asian climate DYnamics aims to reconstruct the Holocene climate variability and regional hydrology in Central Asia along three transects on the Tibetan Plateau. CADY is part of the BMBF research program "Central Asia and Tibet: Monsoon dynamics and geo-ecosystems".
HIMPAC - HImalaya: Modern and PAst Climates is an Indo-German initiative targeted towards understanding the modern and palaeomonsoon variability on seasonal to decadal time scales over the Indian subcontinent.
In the Amudarya Delta, there is a distinct salinity contrast between the low-salinity river water (~ 1g/l), low-salinity confined groundwater of Cretaceous aquifers and the salinity of the unconfined groundwater (10 – 95 g/l) and the Aral Sea (~ 100 g/l).
The use of confocal laser scanning microscopy CLSM in quantitative wood anatomy as a novel advance for developing long chronologies of wood cell structure measurements.
Investigations of the East Asian monsoon system over the last glacial-interglacial cycle are based on sediments of small lakes with high sedimentation rates from South- and Northeast-China. Main aspects of palaeoclimatic reconstructions are variations of precipitation and dust flux, as well as vegetation dynamics.
Central Asia, extending between the Caucasus and the eastern Tibetan Plateau, with a semiarid/arid belt with water shortage to the west and a glaciered mountainous area with very unstable surface conditions to the east, holds a key position for understanding geodynamic and climate processes.
The Near East region encompasses a unique set of contrasting environments, where changes in hydrological regimes are probably the most prominent expressions of climate variability. Environmental changes in this region had a profound impact on prehistoric and early historic cultural evolution of mankind.
Lakes Holzmaar (HZM) and Meerfelder Maar (MFM), located only a few km apart in the Eifel Mountains, Germany, contain long annually laminated sediment records.
The project „Assessment of contemporary vs. Lateglacial/EarlyHolocene climate variability based on isotopes from the NZ kauri tree-ring archive – IsoWoodNZ“ is supported by the International Bureau of the BMBF.
This project funded by the International Bureau of the BMBF studies „Past and Present Response of Woody C3 and C4 Plants to Climate Change using Sophora chrysophylla (C3) and Euphorbia olowaluana (C4) trees in Hawai`i, USA“
Laminated sediments recovered from the maar lake Lago Grande di Monticchio in southern Italy provide detailed information about the regional climatic and environmental development and unique chronostratigraphic information about the explosive activity of nearby (100-540 km) Quaternary Italian volcanoes.
Newly recovered Mýtina Palaeo-Maar is investigated with a multi-disciplinary approach and used as an outstanding late Quarternary palaeoclimate archive.
The origin of non-hydrocarbon gases in the North-German Basin: Sources, migration paths and relative timing of nitrogen release
The North German Basin forms part of the Mid European Basin where natural gas produced from Carboniferous, Permian, and Triassic reservoirs mainly sourced from coal-bearing strata and marine shales of Carboniferous age.
Stratigraphy, from Latin stratum + Greek graphia, is the description of all rock bodies forming the Earth's crust and their organization into distinctive, useful, mappable units based on their inherent properties or attributes in order to establish their distribution and relationship in space and their succession in time, and to interpret geologic history.
