Unexploded ordnance (or UXOs/UXBs, sometimes identified as UO) are explosive weapons (bombs, bullets, shells, grenades, land mines, naval mines, etc.) that did not explode when they were employed and still pose a risk of detonation, potentially many decades after they were used or discarded. This is NOT a complete collection of unexploded ordnance on the seafloor, nor are the locations to be considered exact. The presence and locations of the unexploded ordnance have been derived from graphical representations recorded on NOAA Raster Navigation Charts.

The groundfish data comprises three types of data, showing two gear types and historical areas. The current groundfish data gear types are broken down into gill net and trawl. The historic data represents a combination of gill net, trawl, and hook fisheries. Data collection did not target historic groundfishing areas, but captured that information as offered by participants. Therefore, historical data should not be viewed as a complete representation of effort or distribution, but rather as a sampling of historical groundfish data as provided by interviewees. Other institutions like the Penobscot East Resource Center are prioritizing the collection of historical data about groundfish and may have more resources to add richness to the historical distribution of groundfish. The groundfish data set involves both data collected through the work funded by the Maine Coastal Program and also work conducted previously by the Island Institute using substantially the same methodology. Overall, the groundfish data layers represent the information from about 20 interviewees: current and former groundfish fishermen as well as lobstermen whose fishing areas are adjacent those utilized by the groundfish fleet. Federally managed habitat and mortality closed areas play an important role in the groundfish fishery. This is not reflected in this data very well due to the scale and generalization of the data upon being aggregated. The data gives a sense of the vast area fished off the coast of Maine as well as the complexity of fisheries and gear types across areas. It shows areas of fishing from only selected harbors or regions, however, and represent an incomplete “snapshot” from an ongoing project. It should not be viewed as representing a complete data set for Maine’s fisheries, but rather as one step towards understanding fisheries-use patterns offshore and methods for documenting them.

Blue_mussels is a REGIONS dataset and contains distribution information for blue mussels (Mytilus edulis) for the coast of Maine . Polygons are based on locations indicated by town officials, harvesters, Harbormasters, DMR biologists, DMR specialists or DMR scientists from February 2008 to May 2009. POLYGON codes include: Town, County, Species, NOAA_Chart, Updated, Shape, ACRES, OBJECTID, SHAPE_AREA, SHAPE_LEN, and Source.
