This project established a permafrost monitoring network in this region, providing a baseline of permafrost thermal regimes for assessing future change at a total of 26 automated monitoring stations. Stations have collected year-round temperature data from the active layer and the permafrost starting from the summer of 2011. The strong correspondence between spatial variability in permafrost thermal regime and an existing ecotype map allowed for the development of a map of ‘permafrost thermal classes’ for the broader study region. Further, the annual temperature data was used to calibrate models of soil thermal regimes as a function of climate, providing estimates of both historic and future permafrost thermal regimes...

This collection (known internally at Maryland Geological Survey as Component 9) consists of 1,474 black-and-white aerial photographs (1,472 unique frames plus 2 duplicates) plus 2 index maps which serve as a finding aid for the photographs in the two sub-components of this collection -- DC Collection 1 and DC Collection 2. The photographs are 9 in. by 9 in. in size and cover Washington, DC and vicinity (including portions of Maryland and Virginia). The counties in Maryland covered by these aerial photographs are Anne Arundel, Howard, Montgomery, and Prince George's Counties. No date is printed on these photographs; however, based on features shown in the photographs, Maryland Geological Survey (MGS) estimates...
