Members of sub-projects Z2, Z3 and C8 carried out a joint field campaign between 8. and 26. March 2022. Fieldwork focused on continuing the installation of standard fog collectors (SFCs) associated with mobile and permanent weather stations. Three Onset Hobo mobile weather stations with fog collectors were requested by sub-project B1 and now operate in one of the B1 focus study areas with Tillandsia landbeckii, some 20 km from the city of Caldera (cf. Fig. 1, video). The weather stations were placed in different elevations (between 400 and 700 m asl) along a 3.5 km-long transect. In addition, two further new permanent weather stations with fog collectors were installed in the central and northern CRC focus areas, i.e., in the Salar Grande area (S42) and close to Oficina Dolores (S40; Fig. 2).

In addition, new sub-project C08 took first sediment samples in the southern CRC focus area during the March 2022 field campaign. Samples were taken from surfaces of a coastal alluvial fan in the Paposo area (Fig. 3), where sub-project C02 had already started chronostratigraphical investigations. Further collaboration and coordinated site selection with sub-project C02 is planned for future field work.
