We present the results of comprehensive pre-site surveys and deep drillings in two clay pans in the central Atacama Desert of northern Chile, one of the driest deserts on Earth. The results of the site surveys as well as lithological and downhole-logging data of the deep-drilling operations highlight the potential of the sediment records from the PAG (Playa Adamito Grande) and Paranal clay pans to provide unprecedented information on the Neogene precipitation history of the hyperarid core of the Atacama Desert. 

In this paper, we present the technical choices we made to craft a universal core opening bench. This device has been designed to open sediment cores in polyvinyl chloride (PVC) liners up to 1.5 m long and with 3 mm thick walls. The accepted external diameters are 63 and 90 mm, but this may be customized easily. All plans and 3D shapes are available online at no charge.

We present five new sediment cores, the Rates of Interglacial Sea-level Change and Responses (RISeR) cores, extracted from the southern North Sea. The cores will allow us to study the evolution of the basin in the Quaternary (the last 2.58 million years). The cores reveal widespread soil, wetland, and river deposits, reflecting a lost, predominantly terrestrial, landscape that now sits around 20 m below sea level. Understanding these landscapes is vital, as they form the foundations for a rapidly growing offshore wind industry.
