Displays the location of buoys for the State of Hawaii as recorded on NOAA nautical charts, which are used as aids to navigation (ATONs) to indicate traffic channels, to warn against potential dangers, or for other navigational purposes. Some include lights or radar reflectors to make them visible at night and in conditions of reduced visibility. In the IALA B maritime buoyage system (North and South America), red lateral markers have even numbers and should remain on your right when returning from sea ("red, right, returning") while green lateral markers have odd numbers and should remain on your left. Other colors and color combinations are used for non-lateral markers with a variety of purposes.

Displays the location of marine beacons for the State of Hawaii as recorded on NOAA nautical charts. While buoys float at the surface of the water, beacons are fixed to the sea bottom. Both are used as aids to navigation (ATONs) to indicate traffic channels, to warn against potential dangers, or for other navigational purposes. Some include lights or radar reflectors to make them visible at night and in conditions of reduced visibility. In the IALA B maritime buoyage system (North and South America), red lateral markers have even numbers and should remain on your right when returning from sea ("red, right, returning") while green lateral markers have odd numbers and should remain on your left.

This layer shows coastal channels and waterways that are maintained and surveyed by the U.S. Army Corps of Engineers. These channels are necessary transportation systems that serve economic and national security interests. The possibility of silting is always present. Local authorities should be consulted for the controlling depth. NOAA Charts frequently show controlling depths in a table, which is kept current by the U.S. Coast Guard Local Notice to Mariners.

These data show the boundaries for select vessel routing measures in U.S. waters. These measures are part of an international ships routing system established by the IMO. Routing systems are systems of predetermined routes and related measures that are recommended for use by, and may be made mandatory for, all ships, certain categories of ships or ships carrying certain cargoes when adopted and implemented in accordance with the guidelines and criteria developed by the [IMO] and are designed to contribute to the safety of life at sea, safety and efficiency of navigation, and/or protection of the marine environment. SOLAS Chapter V, reg. 10, para. 1. For coastal and ocean planning. Not for navigation.

NOAA, National Ocean Service, Office of Coast Survey, Marine Chart Division is responsible to build and maintain a suite of more than 1000 nautical charts that are used by commercial and recreational mariners to navigate the United States and U. S. territory waters safely.A Nautical Chart is a graphic portrayal of the marine environment. They are used to lay out courses and navigate ships by the shortest and most economically safe route. They can also serve as base maps for resource management and shoreline development planning by state and local government.Charts depict the location of the shoreline, minimum water depths, aids to navigation, hazards to navigation, the nature and form of the coast, water depths, the general character and configuration of the sea bottom, the rise and fall of the tides, protected areas, and the characteristics of the Earth's magnetism.The suite of charts is compiled and maintained with data provided by federal, state, and private partners such as the National Ocean Service elements, United States Coast Guard, United States Army Corps of Engineers, United States Power Squadron Auxiliary, Port Authorities.The charts are currently available as Lithographically printed paper charts, Electronic Raster Nautical Charts (RNCs), up-to-date paper charts (printed with print on demand technology), and are now offered as Digital Vector Electronic Nautical Charts (ENC).The NOAA RNCs are electronic images of the NOAA paper charts. The NOAA RNCs were productized with a successful Cooperative Research and Development Agreement (CRADA) with private sector partner BSB Electronic Charts, a subsidiary of Maptech, Inc. Andover, Massachusetts. As of November 1, 2005 the NOAA RNC's are available for free download via the NOAA website.

This data set contains vector points depicting locations for access, anchorage, boat ramps, diving sites, locks and dams, marinas, and ports in Northwest Peninsular Florida. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. The entirety of the ESI Human-Use data layers consists of: PARKS-MANAGED AREAS Polygons; NAVIGATION-MARINE Points; POLITICAL-JURISDICTIONAL Polygons, Points; RESOURCE MANAGEMENT Polygons, Points; SOCECON Polygons, Lines, Points; and NATURAL HAZARD Polygons.

The Office of Coast Survey (OCS) has been involved in the development of a NOAA Electronic Navigational Chart (NOAA ENC) suite to support the marine transportation infrastructure and coastal management for a number of years. The NOAA ENC will support all types of marine navigation by providing the official database for electronic charting systems (ECS), including the Electronic Chart Display and Information System (ECDIS). NOAA ENCs support real-time navigation as well as collision and grounding avoidance needs of the mariner, and accommodate a real-time tide and current display capability that is essential for large vessel navigation. NOAA ENCs will also provide fully integrated vector base maps for use in geographic information systems (GIS) that are used for coastal management or other purposes. The NOAA ENCs are in the International Hydrographic Office (IHO) S-57 international exchange format and comply with the ENC Product Specification.

MarineCadastre.gov is a marine information system that provides authoritative ocean data, offshore planning tools, and technical support to the offshore renewable energy community. The project was initiated by the Energy Policy Act of 2005 (P.L. 109-58) - Sec. 388 - Alternative Energy-Related Uses on the Outer Continental Shelf, which directs the secretary of the interior, in cooperation with the secretary of commerce, the commandant of the Coast Guard, and the secretary of defense, to establish an outer continental shelf (OCS) mapping initiative to assist in decision-making related to alternative energy uses on the OCS. At its core, MarineCadastre.gov contains marine cadastral data, which encompass the spatial extent, usage, rights, restrictions, and responsibilities of marine areas, as well as other regionally specific data needed to support planning, management, and conservation of submerged lands and marine spaces. The combination of marine cadastral and regionally specific data provides users with many of the data layers needed for renewable energy siting and other ocean planning efforts. The MarineCadastre.gov National Viewer is intended to be used as a planning and screening tool to inform decisions on ocean uses. It is not intended to be used for precise site selection, but rather to provide the geospatial picture of ocean planning data layers needed to make decisions about where suitable areas exist for offshore activities. MarineCadastre.gov also has more regionally focused viewers within its Map Gallery. Those viewers demonstrate how marine cadastre data can be used along with state or regionally applicable data sets to inform ocean planning decisions.The MarineCadastre.gov Data Registry lists all the data layers that can be found on MarineCadastre.gov with the ability to shop for layers, add these to a cart, and open in a map on ArcGIS Online. There are quarterly updates to the National Viewer and Data Registry. Please sign up for data updates here: https://coast.noaa.gov/digitalcoast/publications/subscribe.

From March 10 - 28, 2021 (Key West, FL to San Juan, Puerto Rico), NOAA Ocean Exploration conducted mapping operations south of Puerto Rico in U.S. waters, aiding in closing bathymetric gaps within this region. EX-22-02 collected 18,850 square kilometers of bathymetry and associated water column data, 18,033 square kilometers of which were within the U.S. Exclusive Economic Zone and Territorial Sea deeper than 200 m. During mapping operations, NOAA Ocean Exploration simultaneously collected EM 304 multibeam sonar bathymetry observations and Simrad EK60/EK80 split-beam fisheries sonar observations of biologic material in the water column, as well as Knudsen 3260 sub-bottom profiler observations of sub-seafloor geologic structure and sediment. A single CTD cast during the expedition validated deep deployment capabilities in preparation for planned CTD operations on EX-22-03. The exploratory mapping operations conducted during this cruise will provide initial characterization of the region, as well as data to support further exploration.

These data provide an accurate high-resolution shoreline compiled from imagery of Port of Astoria, OR-WA . This vector shoreline data is based on an office interpretation of imagery that may be suitable as a geographic information system (GIS) data layer. This metadata describes information for both the line and point shapefiles. 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.
