Australian Acid Brine Lake as a Mars Analog: an Analysis of Preserved Lipids in Shore and Lake Sediments
Introduction: The ephemeral, saline, acidic lakes on the Yilgarn Craton of Western Australia have been suggested as geochemical analogues to Martian paleoterrains that are characterized by the interbedding of large deposits of phyllosilicates and hydrated sulfates [1]. These areas indicate shifting environmental conditions, from the circumneutral wet to alkaline wet conditions that began in the...
متن کاملAlkane and alkanoic acid variations with depth in modern sediments o f Pyramid Lake
-Pyramid Lake, a salt lake in Nevada, has undergone a 30~ reduction in volume over the past 100 yr due to diversion of river inflow for irrigation of farmland. This has altered the depositional-benthic environment and possibly has changed the overall aquatic environment of Pyramid Lake as indicated by changes in the hydrocarbon and monocarboxylic acid content in a sediment core. In the top 30 c...
متن کاملNitrogen cycling in deeply oxygenated sediments: Results in Lake Superior and implications for marine sediments
To understand the nitrogen (N) cycle in sediments with deep oxygen penetration, we measured pore-water profiles to calculate N fluxes and rates at 13 locations in Lake Superior in water depths ranging from 26 to 318 m. Sediments with high oxygen demand, such as in nearshore or high-sedimentation areas, contribute disproportionally to benthic N removal, despite covering only a small portion of t...
متن کاملDon Juan Pond, Antarctica: Near-surface CaCl2-brine feeding Earth's most saline lake and implications for Mars
The discovery on Mars of recurring slope lineae (RSL), thought to represent seasonal brines, has sparked interest in analogous environments on Earth. We report on new studies of Don Juan Pond (DJP), which exists at the upper limit of ephemeral water in the McMurdo Dry Valleys (MDV) of Antarctica, and is adjacent to several steep-sloped water tracks, the closest analog for RSL. The source of DJP...
