In 2009, a consortium of Icelandic geothermal companies known as the Iceland Deep Drilling Project drilled a well (IDDP-1) into Landsvirkjun’s (National Power Company of Iceland) geothermal field within Krafla Caldera. After 2000 m of drilling they encountered magma, as evidenced by quenched rhyolitic glass. This opened the opportunity to access shallow magma at a known location on an actively utilized geothermal field. The Krafla Magma Testbed is the endeavour to establish a magma observation and experimentation platform at depth. This platform will allow us to learn about magmatic process in-situ, how they interact with the host rock and surrounding hydrothermal system, and how they react to perturbations, either as part of energy extraction or even perhaps as part of a hazard mitigation programme. In preparation for accessing near-surface magma there remains a lot of previous and ongoing research that needs to be brought together, as well as research and development challenges that remain to be solved. This session invites contributions related to the Krafla Magma Testbed, and could consist of details of the science plan, previous and ongoing work in understanding the Krafla caldera and geothermal field, as well as work from other volcanic systems that has relevance to near-surface magmatic processes, magma drilling, near-magma subsurface conditions (e.g. temperature gradients, fluid flow and geochemistry, geomechanics and rheology, magma-hydrothermal interaction), subsurface magma modelling, detection and monitoring of near-surface magma bodies, instrumentation of high-temperature wells, deep geothermal energy, volcano monitoring, etc. This list is not exhaustive but gives an indication of the kinds of topics being sought to stimulate exchange and discussions regarding the existing scientific knowledge about this environment, the outstanding scientific needs to access it and the unique opportunities that accessing it could bring to science.
