The Nam Co Drilling Project (NamCore) aims to retrieve and interpret one of the longest sedimentary records of past climate and environmental changes from the Earth’s “third pole” - the Tibetan Plateau. As a result of vast glacial systems, permafrost, and large lakes, the Tibetan Plateau contributes to the “Asian Water Tower” and feeds river systems (e.g. Brahmaputra, Yangtze) that supply water to almost 2 billion people downstream. By recovering long, continuous sediment sequences from Nam Co, one of the largest and deepest lakes on the plateau, NamCore will help to elucidate how the Asian Monsoon system(s) and the Westerlies responded to changing climate boundary conditions in the past, thereby improving our understanding of future climate change scenarios with socio-economic relevance. Site survey seismic data indicate the presence of more than 700 m of well-layered, undisturbed sediments in the lake depocentre, confirming Nam Co as an ideal natural archive located near the northern boundary of the modern monsoon regime. Scientific drilling operations at Nam Co were carried out in June and July 2024 and, in total, the project drilled 1415.45 m, cored 1175.99 m of sediments and recovered 950.77 m of sediment cores, while reaching a maximum depth of 510.2 m below the lake floor.
All datasets provided within the operational dataset (Adolph et al., 202x?) of the ICDP project NamCore (ICDP 5073) include metadata, data and/or images. This document summarizes the explanations of the tables, datasets and images exported from the project database (mDIS NamCore), supplemented by additional information derived from field and laboratory measurements conducted prior to the sampling parties. Furthermore, sampling data from the first three sampling parties are included, and basic definitions of identifiers used within ICDP are introduced.
