Microbial Community Structure of Subglacial Lake Whillans, West Antarctica

open access: yesFrontiers in Microbiology, 2016
Subglacial Lake Whillans (SLW), located beneath ~800 m of ice on the Whillans Ice Stream in West Antarctica was sampled in January of 2013, providing the first opportunity to directly examine water and sediments from an Antarctic subglacial lake.

Enhanced metabolic versatility of planktonic sulfur-oxidizing γ-proteobacteria in an oxygen-deficient coastal ecosystem

open access: yesFrontiers in Marine Science, 2014
Sulfur-oxidizing Gamma-proteobacteria are abundant in marine oxygen-deficient waters, and appear to play a key role in a previously unrecognized cryptic sulfur cycle.

Iron-based microbial ecosystem on and below the seafloor: a case study of hydrothermal fields of the Southern Mariana Trough

open access: yesFrontiers in Microbiology, 2012
Microbial community structures in deep-sea hydrothermal vents fields are constrained by available energy yields provided by inorganic redox reactions, which are in turn controlled by chemical composition of hydrothermal fluids.

Shifts in organic matter character and microbial assemblages from glacial headwaters to downstream reaches in the Canadian Rocky Mountains [PDF]

open access: yesBiogeosciences
Climate change is causing mountain glacial systems to warm rapidly, leading to increased water fluxes and concomitant export of glacially derived sediment and organic matter (OM).
