New Hampshire / Southern Maine Ocean Uses Atlas: Non-Consumptive sector

The Ocean Uses Atlas Project is an innovative partnership between the Coastal Response Research Center (CRRC) and NOAA's Office of Ocean and Coastal Resource Management (OCRM). The Project was designed to enhance ocean management through geospatial data on the full range of significant human uses of the ocean environment from the shorelines of New Hampshire and Southern Maine to the EEZ boundary. The data were gathered from regional ocean experts and users through participatory GIS methods. For more information on the project scope, background and related data products, please visit http://www.crrc.unh.edu/workshops/ocean_uses/index.html or https://coast.noaa.gov/arcgis/rest/services/MarineCadastre/OceanUsesNewHampshireMaine/MapServer.

The New Hampshire / Southern Maine Ocean Uses Atlas Project fills a critical information gap in ocean management by providing an unprecedented, comprehensive, consistent and spatially explicit picture of human uses for management agencies, policy makers and stakeholders interested in sound and equitable ocean governance. Using participatory GIS concepts and applications, the Atlas Project generated spatial data and map products illustrating patterns, intensity, and temporal changes in a wide range of human uses in three broad categories of use: (i) fishing, (ii) non-consumptive, and (iii) industrial activities. The resulting datasets depict patterns of ocean use on a broad scale appropriate for a variety of ocean planning and management needs. Specifically, the data will be used in the Environmental Response Management Application (ERMA) during the March 2010 Spill of National Significance (SONS) drill. This dataset contains the non-consumptive activities, and is part of the larger New Hampshire / Southern Maine Ocean Uses Atlas database.

The Non-Consumptive sector contains 9 ocean uses: -Beach use: includes walking, running, digging, resting, shell collecting, wildlife viewing, driving, camping, kite flying, bonfires, picnicking, dog walking; excludes beach renourishment, dredging, scientific/educational specimen collecting, seascape viewing from boats or from shoreward of the beach, surf fishing, swimming; -Motorized boating: includes personal watercraft, outboard motors, private motorized vehicles; excludes fishing boats and wildlife viewing charters, cruise ships; -Paddling: includes kayaking, canoeing, rowing, outrigger paddling; excludes motorized craft, surfing, wind-surfing; -Sailing: includes sailboats, overnight anchoring; excludes sailing kayaks and canoes; -SCUBA/snorkeling: includes SCUBA diving, tethered diving, snorkeling (free diving); excludes surface swimming; -Surface water sports: includes surfing, wind-surfing, kite surfing; excludes paddled boats, snorkeling; -Swimming: includes short- and long-distance surface swimming any distance from shore; excludes SCUBA diving, tethered diving, snorkeling (free diving); -Tidepooling: includes use of rocky shores for naturalist, leisure, or educational purposes; excludes intertidal collection or subsistence harvest of living marine species (i.e. plants, invertebrates and fish) for consumption, bait, aquaria or research; -Wildlife viewing at sea: includes any commercial boat-based or aerial wildlife viewing at sea; excludes shore-based wildlife viewing; For all uses mapped in this sector, the use footprint and dominant use areas are included in the dataset. The use footprint (aka the Maximum Footprint of Use) includes all areas in which the use is known to occur with some regularity, regardless of frequency or intensity. The dominant use areas include areas where the use is most commonly pursued and are defined as areas within the general use footprint that are routinely used by most users most of the time. Future use areas are also included for certain uses where participants anticipated an increase in spatial extent or intensity. Future use areas reflect an anticipated significant and disproportionate (relative to other areas) change in patterns of use through either a lateral expansion of a dominant use area or an increase in intensity of use, or both in the foreseeable future but within the next ten years.

Attribute accuracy was maintained by comparing data before and after each process step, and by comparing final product to source data.

Workshops were conducted at a maximum scale of 1:100,000. During post processing, original workshop polygons were aggregated to an ordered one-quarter nautical mile squared grid, so exact use locations within each block are not discernible. Data are intended to portray broad patterns for each use at a comparable scale to inform ocean management but are not intended for navigation or enforcement purposes.

All uses in the Non-Consumptive sector were mapped for the entirety of the project area.

Logical consistency was maintained by comparing data before and after each process step, and by comparing final product to source data.
