Prof. Vening Meinesz opened up the oceans for high precision gravimetric observations. Today, his submarine adventures are an inspiration to my science and education in gravimetric research. We will follow him along his voyage aboard the K18, along which I will discuss several applications using global gravity field models. The theory of isostasy allows us the use the static gravity field to study GIA processes in Fennoscandia and North America. Also, observed crustal structure from...

Permian deposits are found in outcrops and in the subsurface of Central Tunisia. Their sedimentary and stratigraphic characteristics and origin are not fully understood and represents the main focus of this work. Base level changes, location of the palaeo-coastline and stratigraphic architecture and sandstone connectivity of formations are insufficiently known. Answering these questions will impact future hydrocarbon exploration and improve the geological understanding of Tunisia. Seismic lines and well data of the Jeffara Basin have...

As part of the Education And Training On Handling Of Research Data IG activities, the Minimal Metadata for Learning Resources Focus Group recommends a minimal set of metadata for learning resources. By comparing and analyzing existing learning resource-related metadata schemas to find the overlaps, the group provides guidance on metadata elements that should be minimally required for purposes of learning resource discovery to those concerned with supporting or providing training resources. This set includes a...

Delft geothermal project (DAPwell) is a planned geothermal well doublet, where relatively cold water is going to be injected through one well into a low enthalpy geothermal reservoir to produce hot water from the other well. The volume of the cold water around the injection well will increase over time and, in the end, result in a thermal breakthrough. Thus, it is essential to trace the time-lapse change in the volume of the cold water...

One of the most important actions to limit climate change is to decrease worldwide CO2 emissions. A large contributor to worldwide CO2 emissions is the production of heat. Therefore, the recently started transition from fossil based fuels to renewable heat sources is of great importance. Renewable heat sources like geothermal and solar energy often exhibit a temporal mismatch between the availability and demand of heat. Excess heat is available in summer while the heat demand...
