The National Data Bouy Center (NDBC) provides hourly observations from a network of about 90 buoys and 60 Coastal Marine Automated Network (C-MAN) stations to help meet these needs. All stations measure wind speed, direction, and gust; barometric pressure; and air temperature. In addition, all buoy stations, and some C-MAN stations, measure sea surface temperature and wave height and period. Conductivity and water current are measured at selected stations.

The High Frequency Radar Network (HFRNet) is being developed to manage, distribute, and display in near-realtime, ocean surface currents measured by a distributed network of shore-based HF radar systems. HFRNet provides reliable data telemetry, archiving, and integrated processing for a growing list of near real-time products in a scaleable manner for a growing user community supported by the Integrated Ocean Observing System.

The Environmental Research Division's Data Access Program aggregates scientific data from diverse local and remote sources and offers a simple, consistent way to download subsets of the data in common file formats and make graphs and maps. In particular ERDDAP enables easy access to oceanographic data from satellites and buoys.

NOAA's nowCOAST is a GIS-based web mapping portal providing integrated, one-stop access to on-line, real-time coastal environmental observations and NOAA forecasts for any region in the coastal United States. NowCOAST provides users with displays of the latest surface weather and ocean observations, satellite cloud imagery, weather radar reflectivity mosaics, sea surface temperature analyses and gridded forecasts.

The World Ocean Atlas is a set of objectively analyzed (1° grid) climatological fields of in situ temperature, salinity, dissolved oxygen, Apparent Oxygen Utilization (AOU), percent oxygen saturation, phosphate, silicate, and nitrate at standard depth levels for annual, seasonal, and monthly compositing periods for the World Ocean. It also includes associated statistical fields of observed oceanographic profile data interpolated to standard depth levels on both 1° and 5° grids

Giovanni is a Web-based application developed by the Goddard Earth Sciences Data and Information Services Center that provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Giovanni is an acronym for the Goddard Earth Sciences Data and Information Services Center Interactive Online Visualization ANd aNalysis Infrastructure.

The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is the NASA data center responsible for archiving and distributing data relevant to the physical state of the ocean.  The PO.DAAC Ocean ESIP Tool (POET) provides interactive, on-line subsetting and visualization of many of PO.DAAC's data products. Viewing options include: latitude-longitude maps, animations, time series plots, and space-time profiles.

The Climatology of Global Ocean Winds (COGOW), is a web-based interactive atlas from which users can retrieve climatological wind maps as well as wind statistics, both in tabular and graphic form, on a 0.5° latitude by 0.5° latitude grid, for almost any particular region of interest. The accuracy of QuikSCAT wind measurements is equivalent to that of observations by well-calibrated buoys.

VDatum is a tool developed by the Office of Coast Survey for the transformation of elevation data from one vertical datum into another. Such transformations are necessary when data from diverse sources are to be combined or compared. Artificial steps or discontinuties can appear in maps and charts if they are built from data based on inconsistent datums. This problem can be particularly acute in coastal areas.

The Topographic and Bathymetric Data Inventory displays the best-available topographic and bathymetric data for the United States. It includes information from two inventories, one conducted by the NOAA Coastal Services Center and one by the Federal Emergency Management Agency (FEMA).
