Carbon accrual in the Atacama Desert

Global and Planetary Change, 2019
Abstract The Atacama Desert is the oldest and driest desert on Earth, nevertheless traces of life have been observed in several places, accumulating residues of organic matter (OM) in the desert soil. We evaluated to which degree the distribution of soil organic carbon (SOC) stocks depends on aridity.

Microbial Life in the Atacama Desert

Science, 2004
In their Report “Mars-like soils in the Atacama Desert, Chile, and the dry limit of microbial life,” R. Navarro-Gonzales et al. found only very low levels of culturable bacteria in the Mars-like soils of the Atacama Desert, and they did not recover DNA (Reports, 7 Nov. 2003, p.

Microflora of extreme arid Atacama Desert soils

Soil Biology and Biochemistry, 2007
Abstract Surface and subsurface soil samples from the most arid region within the Atacama Desert, Chile, were analyzed for total organic carbon (TOC), phospholipid fatty acids (PLFA) and culturable bacteria. TOC content was determined to range between 560 and 765 μg/g. PLFA analysis indicated 2.0×10 6 –1.0×10 7  cell equivalents/g.

Fungal diversity in the Atacama Desert

Antonie van Leeuwenhoek, 2018
Fungi are generally easily dispersed, able to colonise a wide variety of substrata and can tolerate diverse environmental conditions. However, despite these abilities, the diversity of fungi in the Atacama Desert is practically unknown. Most of the resident fungi in desert regions are ubiquitous.

The Atacama Desert Trek: outcomes

Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002
In June and July 1997, Nomad, a planetary-relevant mobile robot, traversed more than 220 kilometers across the barren Atacama Desert in Chile, exploring a landscape analogous to the surfaces of the Moon and Mars. In this unprecedented demonstration, Nomad operated both autonomously and under the control of operators thousands of kilometers away ...

Preandean Atacama Desert Endolithic Microbiology

2020
Endolithic ecosystems are considered environmental refuges for life in arid and hyperarid deserts around the world. The microbial communities colonizing these habitats are of special interest due to their ability to live in a polyextreme environment characterized by scarcity of water and extreme solar radiation.
