This collection hosts outcomes from the ‘Soil Science & Archaeo-Geophysics Alliance’ (SAGA), an international research network funded by the European Cooperation in Science & Technology (COST) for four years (from 26th October 2018 until 25th October 2022) as COST Action SAGA (CA17131).  SAGA is developing, promoting and facilitating scientific activities bringing together geophysics and soil science with the overall goal of maximising interpretation of geophysical data for archaeological investigations. The collection includes SAGA’s proposal and annual reports on scientific activities (workshops, training schools, short-term scientific missions and Conference Grants) carried out by its members and external participants.
