Crater size estimates for large-body terrestrial impact [PDF]

Calculating the effects of impacts leading to global catastrophes requires knowledge of the impact process at very large size scales. This information cannot be obtained directly but must be inferred from subscale physical simulations, numerical ...

Microbial mats of the Tswaing impact crater: results of a South African exobiology expedition and implications for the search for biological molecules on Mars [PDF]

, 2001
We describe microbial mats from the Tswaing impact crater in South Africa. The mats provide insights into the unique biological characteristics of impact craters and can help strategies for the search for biomolecules on ...

Using Environmental DNA Sampling for Simultaneous Detection of Hosts and Their Pathogens: A Case Study With the Critically Endangered Frog Genus Atelopus

Animal Conservation, EarlyView.
Environmental DNA is a powerful tool for simultaneous detection of rare species and their pathogens. We confirmed the presence of Atelopus at multiple sampling locations and found that the concentration of the amphibian pathogen Bd in eDNA samples was correlated with stream characteristics and the pathogen load of the amphibian community.

Effect of impact angle on central-peak/peak-ring formation and crater collapse on Venus [PDF]

Although asymmetry in ejecta patterns and craters shape-in-plan are commonly cited as diagnostic features of impact angle, the early-time transfer of energy from impactor to target also creates distinctive asymmetries in crater profile with the greatest ...

‘Missing persons’: Ancient legacies of human–environment interaction in tropical natural properties inscribed under the 1972 World Heritage Convention

Archaeometry, EarlyView.
Abstract Cultural and natural values form the core of World Heritage designation. Properties displaying both values, however, comprise a fraction of inscriptions (currently c. 3%) to the World Heritage List. In 1992, when that fraction stood at c. 5%, adoption of the popular ‘cultural landscapes’ category of cultural heritage in 1992 was therefore ...

Magnetic signatures of lunar impact craters

Icarus
The hypothesis that the lunar core dynamo once generated a global magnetic field is widely accepted [1–2]. Paleomagnetic analysis of lunar samples shows that the lunar dynamo field operated from about 4.2 Ga to sometime between 1.92 and 0.8 Ga [3–5].
