Tides and Water Levels

The Tides and Waters Levels Tutorial, presented by NOAA's National Ocean Service (NOS), is an overview of the complex systems that govern the movement of tides and water levels. The tutorial is made up of 11 chapters that can be read in or out sequence and include many illustrative and interactive graphics to visually enhance the learning process. To complement the information highlighted in the tutorial, the site also features a Roadmap to Resources page which provides links to additional tutorials and specific tidal and current data offered by NOAA.

Long Island Sound and Connecticut River Ocean Tide Simulation

This site features two animations that are helpful for understanding the distribution of tides in space and time and their relationship to the phases of the moon. The utility of these animated maps is explained by Wesleyan University geologist Susan O'Connell in a short video introduction. The two animated simulations show color-coded water depths for Long Island Sound and the Connecticut River and the location of high and low tides during specific phases of the moon, as well as bathymetric profiles and geographical locations for reference.

Sediment Transport Movies

This site features a collection of 25 freely downloadable brief movies that demonstrate different types of sediment transfer processes in a variety of environments. Videos present both live and laboratory-created conditions and events such as turbidity currents, debris flows, tidal fluctuations, and the formation of dunes and ripples. For example, two live videos by Canadian sedimentologist Gerard Middleton show the effects of tidal processes at the Bay of Fundy, Nova Scotia. There are also four videos which capture the growth of mineral crystals. Text to accompany the videos can be downloaded as a PDF file by clicking the appropriate link.

Mantle Plumes

This site provides a broad suite of information and resources about "hot spots" and the current debate as to their existence. The site features technical tutorials and publications on a variety of mantle plume topics divided into four main categories: localities, mechanisms, generic, and other resources. The site also includes links to current news articles, information about conferences and meetings, and additional resources. Suggestions and contributions to the site are encouraged.

Undersea Landscapes: Bay of Fundy

This site uses text and photos to explain how the physical characteristics of the Bay of Fundy create the unique tides that occur there. It also explains how the extreme tides affect nutrient cycling and plankton in the Bay, mudflats, and salt marshes. A static 3D map shows the areal extent of the Bay and an interactive 3D map explains the concept of vertical exaggeration. A short movie shows real footage of the rise and fall of the legendary tide in one local harbor.

Regional Paleogeographic Views of Earth History

This site presents a series of paleogeographic and plate-tectonic reconstructions that illustrate the broad patterns of the Earth's structural history. Reconstructions of North America, Colorado Plateau, SW North America, and Mesozoic terrane accretion. Older Mediterranean, Central and Southern Asia views are also available. Reconstructions by geologist Ron Blakey (formerly Northern Arizona University) and Colorado Plateau Geosystems, Inc.

Paleogeography of the Southwestern US

This site features maps of the paleogeography of the Southwestern US from 1.8 billion years ago to 10 million years ago. The images were prepared by placing stratigraphic, tectonic, and sedimentologic data on a base map, plotting land versus sea over this data, and then adding climatic data and detailed landforms such as mountains, shelf edges, rivers, arc-trench systems, and lowlands. The maps are organized by time period and when viewed in sequence they show the paleogeographic evolution of the region. Two different interpretations are presented; one showing a tectonic evolution in which most elements of the western US were derived from the North American continent, and the other depicting a tectonic history of exotic terrain accretion.

The Canadian Cordillera

This site provides numerous diagrams, maps, and cross sections of the terranes and tectonic elements of the Canadian Cordillera and northwestern North America. The site also features several abstracts about the source and mineralogy of Cordilleran rocks and whether or not terranes are of a native or exotic origin.

NOAA Interactive GIS Climate Maps

This website contains an interactive GIS map with global temperatures, precipitation, ecosystems, population and other layers. The tool can zoom in and out, provide limited geographic information, and display a variety of climatic information.

Climate Diagnostic Center Plots

Through static map interface, the Climate Diagnostic Center provides access to plots of current and historical United States temperature, precipitation and PDSI drought maps. The interface allows users to plot the raw data and view map visualizations of data.
