New Elements Issue: Alkaline Lakes

Alkaline lakes are incredibly dynamic, unique, and fascinating biogeochemical environments. This thematic issue leverages the authors’ multidisciplinary insights to portray alkaline lakes’ biogeochemical, mineralogical, and geological importance for both science and society. The articles individually explore the unique conditions leading to the formation of alkaline lakes, the distinctively productive microbial ecosystems that inhabit them, their distinguishing chemistry and mineralogy, their role as societally important economic resources....

All EAG members have online access to current and past issues of Elements. Members who have selected to receive print copies of Elements, will shortly receive the latest issue by post (log into the EAG Membership Platform to verify your preferences and postal address).
