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...

Low-altitude (80 and 100 meters above ground level) digital images were collected at Sage Lot Pond in Waquoit, Massachusetts, two sites on the Mill River in Taunton, MA, Great Marsh in Barnstable, MA, the Wells National Estuarine Research Reserve in Wells, ME, and on the Woods Hole Oceanographic Institution Quissett Campus in Woods Hole, MA using 3DR Solo unoccupied aircraft systems (UAS) during 2018. These images were collected to support science and data needs in wetland research, topographic mapping, and landcover detection at the U.S. Geological Survey Woods Hole Coastal and Marine Science Center. The imagery and associated ground control points can be used to create Digital Elevation Models (DEMs), orthoimages,...

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...

This collection (known internally at Maryland Geological Survey as Component 7) consists of 48 high-altitude, 9 in. by 9 in. infrared aerial photographs (48 unique frames). The photographs date from 1970-1974 and were flown over ten counties in Maryland and some small portions of Virginia along the Maryland border. The counties in Maryland covered by these photographs include Anne Arundel, Baltimore, Calvert, Carroll, Charles, Frederick, Harford, Howard, Montgomery, and Prince George?s Counties. The scale of these photographs is not printed on the photographs; however, Maryland Geological Survey (MGS) calculates the scale to be approximately 1:120,000 for the Series 74-039 photographs; approximately 1:140,000...
This project resulted in an extensive mapping of coastal change along the entire coastline of the Western Alaska Landscape Conservation Cooperative (LCC). The work provides important baseline information on the distribution and magnitude of landscape changes over the past 41 years. The extent of change to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons, was known to be substantial in some areas along the coast (e.g., portions of the Yukon–Kuskokwim Delta), although the extent of change along the full Bering Sea coast was not well documented. With this analysis, changes can be summarized for different land ownerships or other units to assess the extent of recent...

The western coastline of Alaska is highly susceptible to coastal storms, which can cause coastal erosion, flooding, and have other pernicious effects to the environment and commercial efforts. The reduction in ice coverage due to climate change could potentially increase the frequency and degree of coastal flooding and erosion. Further, estuaries and delta systems act as conduits for storm surges, so when there is less nearshore ice coverage, these systems could introduce storm surge into terrestrial environments unaccustomed to saline intrusion, flooding, or other alien biogeochemical factors.‚ÄčThis project quantified the effect of reduced nearshore ice coverage on coastal flooding. The project developed a large...
The objective of this project was to produce an Alaskan Existing Vegetation Type (AKEVT) map at 30m resolution for a portion of the Western Alaska Landscape Conservation Cooperative (WALCC) region using a very consistent (2000 +/- 1 yr.) remote sensing data set (Landsat 7 ETM+) and the same methodology. The mapped area encompasses the western and northern parts of the WALCC region, plus the Kodiak Archipelago.

A high spatial resolution storm surge model was developed for the YK Delta area to assess biological impacts of storm surges under current and future climates. Storm surges are expected to be more frequent and more severe in the YK Delta area due to climate change and sea level rise. The biological impacts in the YK Delta due to the changed storm surges could be extreme.The model was assessed with respect to measured water level data at the coast and, where available, spatial extent of inundation, for 6 storms from the period 1992 to 2011. In total, inundation projections from 9 historical storms (5 from the assessment + 4 others) were developed. For each storm, an spatial inundation index (time-integral of water...

This collection (known internally at Maryland Geological Survey as Component 5) consists of 4,720 items – 4,715 black-and-white aerial photographs (4,688 unique frames plus 27 duplicates) and 5 associated index maps. The aerial photographs were flown or acquired by the U.S. Geological Survey (USGS) and organized on a 7.5-minute quadrangle basis. The photographs are black-and-white and approximately 9 in. x 9 in. in size. The scale of the aerial photography varies but ranges from approximately 1:12,000 to 1:35,400. These photographs date from 1936-1991 and were donated to the Maryland Geological Survey (MGS). The index maps serve as a finding aid for several of the flight series flown over five quadrangles...

The "Historical Aerial Photographs of Maryland, 1937-1990, County Collection" consists of black and white aerial photos (9"x9", 1:20,000-scale) from several time periods: 1937-1938, 1949, 1951-1953, 1957, 1961-1964, 1968, 1970-1972, 1979-1981, and 1983-1990. These photographs were usually flown or otherwise acquired by the U.S. Department of Agriculture (USDA), the U.S. Geological Survey (USGS), or the private firm Air Photographics, Inc. (API). USDA and USGS photographs were donated to the Maryland Geological Survey (MGS), mainly by the Maryland State Highway Administration (SHA). MGS purchased the copyrighted API photographs. Due to copyright limitations, the public may view the paper API photographs but...

This project used previously collected ShoreZone imagery to map nearly 1,600 km of coastline between Wales and Kotzebue. With additional mapping supported by the Arctic LCC and National Park Service, this effort completed the Kotzebue Sound shoreline, which now has been included in the state-wide ShoreZone dataset. The complete ShoreZone dataset for the region was used to conduct a coastal hazards analysis and create maps that identify areas undergoing rapid coastal erosion and areas that are sensitive to inundation by storm surge and sea level rise.‚Äč

This collection (known internally at Maryland Geological Survey as Component 2) consists of 505 enlargements of unrectified, black-and-white aerial photographs flown along Maryland's barrier islands during 13 different time periods (or "sets") between October 1952 and July 1964. Each of the photographs in the collection is about 2 feet x 2 feet in size. Some of the photographs have a scale of 1:14,400 or 1:6,000 stamped on the front. On the backs of many of the photographs is another stamp of "1" = 200 ft". The photographs cover the Maryland section of two narrow barrier islands that lie along Maryland's Atlantic coast, separated by the Ocean City Inlet: Fenwick Island to the north and Assateague Island to the...
