These online resources are meant to guide students and educators to topics presented in the online tides and water levels tutorial. The following links will take you to specific Web pages created and managed by NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS). CO-OPS predicts, records and distributes oceanographic and meteorological data from thousands of monitoring stations in U.S. coastal and territorial waters.

"Our Restless Tides" provides comprehensive information about the astronomical and physical forces that cause and affect the world's tides. Detailed diagrams and mathematical formulae illustrating the forces acting on the world's oceans are presented.

The "Glossary of Tide and Current Terminology" is and indispensable reference tool lists and defines more than 400 terms and concepts concerned with the tidal phenomena and its measurement.
The "Physical Oceanographic Real Time System" (PORTS®) website provides real-time oceanographic and meteorological data for 15 major U.S. harbors. After selecting a particular harbor, you can view the types and geographic placement of different sensors in that area by clicking on the sensor locations highlighted on the area maps. To zoom in on a particular area where an instrument is stationed, click on the "plus" symbol in the upper left hand side of the image. You can reorient the image by "dragging" it with your mouse or using the arrow buttons on the upper left hand side of the image. To view specific data for a particular sensor in graphic format click on the image of data graph you wish to view. To view the data in ASCII, or text format, scroll down the page of the graphic presentation and click on the link to the data set you want to see.
This website provides you with tidal predictions computed by CO-OPS for more than 3000 tidal current stations. Click on the year for which you want tidal prediction data. This opens a new page with a list of states and other areas for which there are tide stations on the left side of the page. Clicking on a state name displays a list of regions within that state. Clicking on a region name will present a list of the tidal current stations in the area. These stations are listed geographically. This will make finding the location you are interested in, or a nearby station, simpler.
Unlike tide stations, which are normally located along the shoreline, most tidal current stations are located offshore in channels, rivers, and bays. These stations are often named for the channel, river, or bay in which they are located or for a nearby navigational reference point. A map or some personal knowledge of the area may help you identify stations.

"Understanding Tides" is a technical publication authored by Stacy Dopp Hicks, provides in-depth explanations of many aspects of tides, including Gravitational Attraction, Sun-Earth and Moon-Earth Systems, Spring and Neap Tides, Tide-Generating Forces, Tidal Waves in Gulfs and Estuaries, Tidal Bores, and Tidal Harmonic Constituents.
