These data were automated to provide an accurate high-resolution historical shoreline of Brunswick, ME suitable as a geographic information system (GIS) data layer. These data are derived from shoreline maps that were produced by the NOAA National Ocean Service including its predecessor agencies which were based on an office interpretation of imagery and/or field survey. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.

Click on a parcel to open a popup balloon listing groundwater, soil and use restrictions for that parcel. Each popup also contains a link to download the applicable FOST/FOSL(s) for the parcel. COLOR CODING OF EACH PARCEL REFERS ONLY TO SOIL RESTRICTIONS! You must open the popup to see other restrictions.Access to or contact with groundwater ANYWHERE on Brunswick Landing is strictly prohibited without prior written approval by the US Navy, USEPA and Maine DEP. This includes water that may fill an excavation during construction work.Residential, recreational and/or similar uses are PROHIBITED on certain parcels. Please refer to the restrictions listed for each parcel for additional information.Note that the color of parcel in this map refers ONLY to level of soil disturbance restrictions:RED parcel: Property owner must obtain written approval from the Navy, USEPA and Maine DEP prior to work to disturb ANY amount of soil for ANY reason.YELLOW parcel: Property owner must stop work and notify Navy, USEPA and Maine DEP if previously unknown contamination such as stained or odiferous soil is encountered.BLUE parcel: No approval or notification is necessary (though notification of Maine DEP is recommended if previously unknown contamination is encountered).

Point locations of about 100 glaciomarine deltas in Maine referenced in Thompson, Woodrow B., Crossen, Kristine J., Borns, Harold W., Jr., and Andersen, Bjorn G., 1989, Glaciomarine deltas of Maine and their relation to late Pleistocene-Holocene crustal movements: in Anderson, Walter A., and Borns, Harold W., Jr. (editors), Neotectonics of Maine: studies in seismicity, crustal warping, and sea level change: Maine Geological Survey, Bulletin 40, p. 43-67, 25 p., 16 figs., 2 appendices, abstract. The elevations of the contacts between the topset and foreset beds of 65 deltas in Maine and New Brunswick were measured in order to locate the positions of sea level to which the deltas were graded. There are another 40 delta locations without surveyed elevation displayed.

This sediment database contains location, description, and texture of samples taken by numerous marine sampling programs. Most of the samples are from the Atlantic Continental Margin of the United States, but some are from as diverse locations as Lake Baikal, Russia, the Hawaiian Islands region, Puerto Rico, the Gulf of Mexico, and Lake Michigan. The database presently contains data for over 27,000 samples, which includes texture data for approximately 3800 samples taken or analyzed by the Atlantic Continental Margin Program (ACMP), a joint U.S. Geological Survey/Woods Hole Oceanographic Institution project conducted from 1962 to 1970. As part of the ACMP, some historical data from samples collected between 1955 and 1962 were also incorporated into the dataset.

This dataset contains the seagrass beds delineated in 2022 in Casco Bay, from Cape Elizabeth to Cape Small in Phippsburg. Polygons were screen digitized from aerial imagery flown at low tide on July 16th, 2022. Imagery was captured using a Vexcel Eagle 80-mm Mark 3 aerial camera mounted on a fixed wing aircraft and flown at an elevation of approximately 9,500 feet. Polygons were refined based on field verification efforts that took place between August 29 and September 27, 2022. Field verification was carried out on foot by Old Brunswick Road at the New Meadows River and by boat using a Maine DEP vessel (20-foot Maritime Skiff with a 115 horse outboard motor), Ocean Systems High-Definition (HD) underwater video camera and SeaViewer 950 Sea-Drop Analog underwater video camera, and Eos Positioning Systems Arrow Gold GNSS GPS systems that pair wirelessly to Android powered ruggedized field tablets capable of submeter accuracy. Each seagrass bed is named by sequential number moving from southwest to northeast along the coast, then back southeast along the islands, which is provided in the ‘Name’ column. These beds are further divided into polygons by percent cover. Polygons are labeled with a unique identifier consisting of sequential numbers in the ‘Id’ column. A singular bed can consist of several Ids. Percent cover categories and percentages are based on those established by Orth et al. (1991), where 1=0-10% cover (very sparse), 2=10-40% cover (sparse), 3=40-70% cover (moderate), 4=70-100% cover (dense). This seagrass polygon shapefile also contains fields for whether the bed was field verified in 2022 (Y=yes or N=no) and whether there is corresponding underwater video footage (Y=yes, N=no). Field verified beds were verified only in part, meaning one or more transects were placed along the perimeter of the bed to confirm seagrass presence and aerial signatures; bed boundaries were not verified in their entirety. Field verification refers to whether the bed (Name field) was visited, it does not account for individual parts of the bed (Id field) with differing cover classes, though often verification occurred in more than one cover class per bed. Underwater video is present for most of the field verified beds but is lacking in some areas due to video transfer errors. The video column corresponds to the named underwater video file, which corresponds to transect name. Species and comment fields are also incorporated in this dataset. Species are only noted if directly observed by underwater video or by visual observations in shallow water. Widgeon grass was observed only in the New Meadows River area off of Old Brunswick Road from samples washed up near shore.
