Schematic diagram showing the relative depths of the CROMO well array, Quarry Valley and Core Shed Wells, with reference to the lithostratigraphic levels from CSW1-1 cores. Depth of the well, in meters, is shown below each well in the cartoon. In the field, water levels differed slightly. Stars suggest zones of inferred lateral flow of water from formation in CSW1-4 and QV1-3 . Redrawn after Cardace et al. (2013). -- Frontiers in Microbiology

Lipid Biomarkers Reveal Dominance Of Aerobic Methanotrophy In A Continental Serpentinizing System

by Keith CowingApril 3, 2026April 3, 2026

Sources and sinks of methane within an advanced serpentinization-influenced system were investigated at the Coast Range Ophiolite Microbial Observatory (CROMO) in Lower Lake, California. Subsurface water-rock reactions at CROMO contribute […]

DNA Reveals That Unique Microorganisms Evolved At Earth’s Poles

by Keith CowingFebruary 15, 2024February 15, 2024

Communities of microorganisms at the bottom of polar lakes evolved independently from other regions, influenced by the particular geological, biological and climate history of their regions. The unique character of […]
