Ice Planet Orbital Recon: Greenland’s Changing Ice

by Keith Cowing

Greenland is the world’s largest island and about 80% of its surface is covered by the Greenland Ice Sheet, the second largest ice mass on Earth after the Antarctic Ice […]

Dew And Frost Do Not Serve As Water Sources For Rock-dwelling Organisms In The Dry Valleys Of Antarctica

by Keith Cowing

Rock-dwelling chlorolichens and cyanobacteria provide most of the total biomass of the ice-free zone of Antarctica, i.e., the McMurdo Dry Valleys (MDV), and yet, the water sources of MDV are […]

Phenylobacterium ferrooxidans sp. nov., Isolated From A Sub-surface Geothermal Aquifer In Iceland

by Keith Cowing

A novel bacterial strain, HK31-GT, was isolated from a subsurface geothermal aquifer (Hellisheidi, SW-Iceland) and was characterized using a polyphasic taxonomic approach. Phylogenetic analysis of 16S rRNA gene along with […]

Thermophysical Properties of Europa’s Surface Constrained by Galileo Photopolarimeter-Radiometer Temperature Measurements

by Keith Cowing

Thermal measurements constrain the physical properties of icy satellite surfaces, including grain size, porosity, and regolith structure. On Europa, analyses of the Galileo Photopolarimeter-Radiometer (PPR) dataset revealed thermal inertia heterogeneities, […]
