A new global database of Mars impact craters ≥1 km: 1. Database creation, properties, and parameters

Development of a global land cover characteristics database and IGBP DISCover from 1 km AVHRR data

Researchers from the U.S. Geological Survey, University of Nebraska– Lincoln and the European Commission’s Joint Research Centre, Ispra, Italy produced a 1 km resolution global land cover characteristics database for use in a wide range of continentalto global-scale environmental studies. This database provides a unique view of the broad patterns of the biogeographical and ecoclimatic diversity...

Iranian Brain Imaging Database: A Neuropsychiatric Database of Healthy Brain

Introduction: The Iranian Brain Imaging Database (IBID) was initiated in 2017, with 5 major goals: provide researchers easy access to a neuroimaging database, provide normative quantitative measures of the brain for clinical research purposes, study the aging profile of the brain, examine the association of brain structure and function, and join the ENIGMA consortium. Many prestigious databases...

Deep Craters on Mars Page 1 Deep Impact Craters in the Isidis and Southwestern Utopia Planitia Regions of Mars: High Target Material Strength as a Possible Cause,

Using THEMIS, MOC and MOLA data, we have found 120 craters in the diameter range 6 11.2 km that have unusually high depth/diameter (d/D) ratios (i.e., 0.0012) within southwestern Utopia Planitia and Isidis Planitia, Mars (Figure 1). Previous studies [1, 2, 3] noted a concentration of deep simple craters located mainly in SW Utopia Planitia suggesting that the deep simple craters could be caused...
