    Description: Because geoscientific research often occurs via community-instigated bursts of activity with multi-investigator collaborations variously labelled as e.g., years (The International Polar Year IPY), experiments (World Ocean Circulation Experiment WOCE), programs (International Ocean Discovery Program), missions (CRYOSAT spacecraft), or decades (The International Decade of Ocean Exploration IDOE), successful attainment of research goals generally requires skilful scientific project management. In addition to the usual challenges of matching scientific ambitions to limited resources, on-going coordination and specifically project management, planning and implementation of polar science projects often involve many uncertainties caused by, for example, unpredictable weather or ocean and sea ice conditions, large-scale logistical juggling; and often these collaborations are spatially distributed and take place virtually. Large amounts of funding are needed to procure the considerable infrastructure and technical equipment required for polar expeditions; permissions to enter certain regions must be requested; and potential risks for expedition members as well as technical issues in extreme environments need to be considered. All these aspects are challenging for polar science projects, which therefore need a well thought-through program including a realistic alternative “plan B” and possibly also a “plan C” and “plan D”. The four most challenging overarching themes in polar science project management have been identified: international cooperation, interdisciplinarity, infrastructure, and community management. In this paper, we address ongoing challenges and opportunities in polar science project management based on a survey among 199 project and community managers and an additional of 85 project team members active in the field of polar sciences. Case studies and survey results are discussed with the conclusive goal to provide recommendations on how to fully reach the potential of polar sciences project and community management.

    Description: In the context of the German-Korean Energy Policy Dialogue, integration of renewable power sources and smart grids have been identified as topics with high relevance. This study aims to support mutual learning and exploration of new fields for collaboration by identifying similarities and differences in the respective status quos, strategies and policies in both countries. After a short introduction to the South Korean energy situation, Chapter 2 provides an overview of the South Korean power market, its situation regarding renewable power sources and the Korean definition of smart grids. Chapter 3 of this study highlights the major South Korean energy strategies and regulatory frameworks relevant to integration of renewable energies and smart grids. In Chapter 4, the status and perspectives of renewable energy sources integration and smart grids in South Korea are discussed, presenting various demonstrative examples, new business models and the current situation of technology deployment. Chapter 5 puts South Korea in the global context and compares it to Germany. Finally, Chapter 6 draws conclusions and presents recommendations on suitable areas for mutual learning.

    Description: Reconstructions of Quaternary climate are often based on the isotopic content of paleo-precipitation preserved in proxy records. While many paleo-precipitation isotope records are available, few studies have synthesized these dispersed records to explore spatial patterns of late-glacial precipitation δ18O. Here we present a synthesis of 86 globally distributed groundwater (n = 59), 
cave calcite (n = 15) and ice core (n = 12)
 isotope records spanning the late-glacial (defined as
 ~ 50000 to ∼ 20000 years ago) to the late-Holocene (within the past ∼5000 years). We show that precipitation δ18O changes from the late-glacial to the late-Holocene range from −7.1 ‰ (δ18Olate-Holocene 〉 δ18Olate-glacial) to +1.7 ‰ (δ18Olate-glacial 〉 δ18Olate-Holocene), with the majority (77 %) of records having lower late-glacial δ18O than late-Holocene δ18O values. High-magnitude, negative precipitation δ18O shifts are common at high latitudes, high altitudes and continental interiors (δ18Olate-Holocene 〉 δ18Olate-glacial by more than 3‰). Conversely, low-magnitude, positive precipitation δ18O shifts are concentrated along tropical and subtropical coasts (δ18Olate-glacial 〉 δ18Olate-Holocene by less than 2 ‰). Broad, global patterns of late-glacial to late-Holocene precipitation δ18O shifts suggest that stronger-than-modern isotopic distillation of air masses prevailed during the late-glacial, likely impacted by larger global temperature differences between the tropics and the poles. Further, to test how well general circulation models reproduce global precipitation δ18O shifts, we compiled simulated precipitation δ18O shifts from five isotope-enabled general circulation models simulated under recent and last glacial maximum climate states. Climate simulations generally show better inter-model and model-measurement agreement in temperate regions than in the tropics, highlighting a need for further research to better understand how inter-model spread in convective rainout, seawater δ18O and glacial topography parameterizations impact simulated precipitation δ18O. Future research on paleo-precipitation δ18O records can use the global maps of measured and simulated late-glacial precipitation isotope compositions to target and prioritize field sites.

    Description: While the Paris Agreement (PA) has enshrined ambitious long-term objectives, the current level of action of the Parties to the Agreement falls far short of this ambition, as is recognised in the very COP decision adopting the Agreement. The Global Stocktake (GST) established in Art. 14 of the PA is a key element to address this problem. Its purpose is to review the implementation of the PA and to assess the progress made towards the collectively agreed goals. The aim of this report is to develop recommendations on how to maximise the potential impact of the GST. The report starts from a perspective of what the GST could ideally do, irrespective of decisions already taken under the UNFCCC and other political constraints. In the second step, the report takes these limitations into account and suggests ways for how to nonetheless work towards the desired outcome.

    Description: The Argentine margin contains important sedimentological, paleontological and chemical records of regional and local tectonic evolution, sea level, climate evolution and ocean circulation since the opening of the South Atlantic in the Late Jurassic–Early Cretaceous as well as the present-day results of post-depositional chemical and biological alteration. Despite its important location, which underlies the exchange of southern- and northern-sourced water masses, the Argentine margin has not been investigated in detail using scientific drilling techniques, perhaps because the margin has the reputation of being erosional. However, a number of papers published since 2009 have reported new high-resolution and/or multichannel seismic surveys, often combined with multi-beam bathymetric data, which show the common occurrence of layered sediments and prominent sediment drifts on the Argentine and adjacent Uruguayan margins. There has also been significant progress in studying the climatic records in surficial and near-surface sediments recovered in sediment cores from the Argentine margin. Encouraged by these recent results, our 3.5-day IODP (International Ocean Discovery Program) workshop in Buenos Aires (8–11 September 2015) focused on opportunities for scientific drilling on the Atlantic margin of Argentina, which lies beneath a key portion of the global ocean conveyor belt of thermohaline circulation. Significant opportunities exist to study the tectonic evolution, paleoceanography and stratigraphy, sedimentology, and biosphere and geochemistry of this margin.

    Description: In July 2007 GFZ hosted ILP’s first Potsdam Conference, titled “Frontiers in Integrated Solid Earth Sciences”. The results of this meeting were presented in an over 400 pages large Springer book, the first volume of a new series on the International Year of Planet Earth (IYPE). In October 2010 ILP’s Second Potsdam Conference took place, entitled “Solid Earth – Basic Science for the Human Habitat”, again in Potsdam. More than 70 scientists from more than 20 states worldwide came together and shared their results, ideas and visions. This time, in September 2015, ILP’s 35th birthday was the motivation for “Celebrating Excellence in Solid Earth Sciences”. Together with more than 50 scientists, members of the ILP Task Forces and Coordinating Committees, the ILP bureau and ILP’s office came together for three days in September.

    Description: The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project focuses on mountain building processes in a major mid‐Paleozoic orogen in western Scandinavia and its comparison with modern analogues. The project investigates a subduction‐generated complex (Seve Nappes) and how these in part under ultra‐high pressure conditions metamorphosed outer continental margin and continent‐ocean transition zones (COT) assemblages were emplaced onto the Baltoscandian platform and there influenced the underlying allochthons and the basement in a section provided by two fully cored 2.5 km deep drill holes. This operational report concerns the first drill hole, COSC‐1 (ICDP 5054‐1‐A), drilled from early May to late August 2014. It sampled a thick section of the lower part of the Seve Complex and was planned to penetrate its basal thrust zone into the underlying lower grade metamorphosed allochthon. The drill hole reached a depth of 2495.8 m and nearly 100 % core recovery was achieved. Although planning was based on existing geological mapping and new high‐resolution seismic surveys, the drilling resulted in some surprises: the Lower Seve Nappe proved to be composed of rather homogenous gneisses, with only subordinate mafic bodies and its basal thrust zone was unexpectedly thick (〉 800 m). The drill hole did not penetrate the bottom of the thrust zone. However, lower grade metasedimentary rocks were encountered in the lowermost part of the drill hole together with garnetiferous mylonites tens of metres thick. The tectonostratigraphic position is still unclear and geological and geophysical interpretations are under revision. The compact gneisses host only 8 fluid conducting zones of limited transmissivity between 300 m and total depth. Downhole measurements suggest an uncorrected average geothermal gradient of ~20°C/km. The drill core was documented on‐site and XRF scanned off site. During various stages of the drilling, the borehole was documented by comprehensive downhole logging. This operational report provides an overview over the COSC‐1 operations from drilling preparations to the sampling party and describes the available datasets and sample material.
