Associate Professor Mark Holzer's recent paper on silicon isotopes in the ocean, written with co-author Mark Brzezinski (UCSB), has featured as the cover story of this month's issue of Global Biogeochemical Cycles journal (GBC).

GBC presents research on regional to global biogeochemical interactions, as well as more local studies that demonstrate fundamental implications for biogeochemical processing at regional or global scales. Published papers draw on a wide array of methods and knowledge and extend in time from the deep geologic past to recent historical and potential future interactions. This broad scope includes studies that elucidate human activities as interactive components of biogeochemical cycles and physical Earth Systems including climate.

GBC is a major international journal with an impact factor of 4.528.
