Abstract: Shaped and filled by the Rhine Glacier: the overdeepened Tannwald Basin in southwestern Germany Bennet Schuster, Lukas Gegg, Sebastian Schaller, Marius W. Buechi, David C. Tanner, Ulrike Wielandt-Schuster, Flavio S. Anselmetti, and Frank Preusser Sci. Dril., 33, 191–206, https://doi.org/10.5194/sd-33-191-2024, 2024 The Tannwald Basin, explored by drilling and formed by repeated advances of the Rhine Glacier, reveals key geological insights. Ice-contact sediments and evidence of deformation highlight gravitational and glaciotectonic processes. ICDP DOVE 5068_1_C core data define lithofacies associations, reflecting basin infill cycles, marking at least three distinct glacial advances. Integrating these findings aids understanding the broader glacial evolution of the Lake Constance amphitheater. PubDate: Thu, 04 Jul 2024 10:16:17 +020 DOI: 10.5194/sd-33-191-2024 2024

Dril., 33, 173–190, https://doi.org/10.5194/sd-33-173-2024, 2024 We built six observatory stations in central Italy to monitor a fault potentially capable of generating a strong earthquake. Each site has 80–160 m deep wells equipped with strainmeters and seismometers. At the surface, we placed GNSS antennas and seismic and meteorological sensors. All data, which are open access for the scientific community, will help us to better understand the complex physical and chemical processes that lead to the generation of the full range of slow and fast earthquakes.

Layers there are about vertical; we drilled sideways. Sedimentary strata from eight boreholes showed that they had been deposited in rivers, sandy shorelines, tidal flats, estuaries, and the ocean. Some have well-preserved remnants of microbes. We will learn how life was established on a planet which would appear very inhospitable to us nowadays.

Dril., 33, 93–108, https://doi.org/10.5194/sd-33-93-2024, 2024 The Deep Drilling in the Turkana Basin project seeks to determine the relative impacts of tectonics and climate on eastern African ecosystems. To organize goals for coring, we hosted a workshop in Nairobi, Kenya, which focused on how a 4 Myr sedimentary core from Turkana will uniquely address research objectives related to basin evolution, past climates and environments, and modern resources. We concluded that a Pliocene to modern record is best accomplished through a two-phase drilling project. PubDate: Mon, 17 Jun 2024 12:17:53 +020 DOI: 10.5194/sd-33-93-2024 2024

Coastal plain sediments can resolve this uncertainty, but their discontinuous nature requires numerous sites to constrain events. Workshop participants identified 10 drill sites that target the PETM and other interesting intervals. Our post-drilling research will provide valuable insights into Earth system responses.

Dril., 33, 33–46, https://doi.org/10.5194/sd-33-33-2024, 2024 The Greenland ice sheet is highly sensitive to global warming and a major contributor to sea level rise. In Northeast Greenland, ice–ocean–tectonic interactions are readily observable today, but geological records that illuminate long-term trends are lacking. NorthGreen aims to promote scientific drilling proposals to resolve key scientific questions on past changes in the Northeast Greenland margin that further affected the broader Earth system.

Dril., 33, 21–31, https://doi.org/10.5194/sd-33-21-2024, 2024 Lake Victoria is home to the largest human population surrounding any lake in the world and provides critical resources across eastern Africa. It is vital to understand the connection between the lake and climate and how it has changed through its history, but to do so we need a complete archive of the sedimentary record. To evaluate the Lake Victoria basin as a potential drilling target, ~50 scientists met in Dar es Salaam, Tanzania, in July 2022 for the Lake Victoria Drilling Project workshop.

Dril., 32, 101–111, https://doi.org/10.5194/sd-32-101-2023, 2023 Natural hazards associated with the ocean can have a direct impact on coastal populations and even affect populations located far away from the coast. These hazards may interact, and they include tsunamis that result in major damage and catastrophic loss of life and submarine landslides, which themselves can produce tsunamis and damage subsea infrastructure.

Abstract: Poor Man's Line Scan – a simple tool for the acquisition of high-resolution, undistorted drill core photos Lukas Gegg and Johann Gegg Sci. Dril., 32, 55–59, https://doi.org/10.5194/sd-32-55-2023, 2023 Geoscientists working with drill cores often struggle with proper photo documentation. We present a simple smartphone-based setup for acquiring high-resolution undistorted core pictures as an alternative to state-of-the-art commercial line scan imaging systems that are typically expensive and inflexible. It makes use of the phone's panoramic picture mode while being guided along the core in question on a rail, and the resulting images are of similar quality to classic line scan photos.

Abstract: Coring tools have an effect on lithification and physical properties of marine carbonate sediments David De Vleeschouwer, Theresa Nohl, Christian Schulbert, Or M. Bialik, and Gerald Auer Sci. Dril., 32, 43–54, https://doi.org/10.5194/sd-32-43-2023, 2023 Differences exist in International Ocean Discovery Program (IODP) sediment lithification depending on the coring tool used. Advanced piston corers (APCs) display less pronounced lithification compared to extended core barrels (XCBs) of the same formation. The difference stems from the destruction of early cements between sediment grains and an acoustic compaction caused by the piston-core pressure wave. XCB cores provide a more accurate picture of the lithification of the original formation. PubDate: Thu, 26 Oct 2023 10:15:38 +020 DOI: 10.5194/sd-32-43-2023 2023
