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.
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.
Exploring Our Dynamic Planet: Jules Verne Voyager, Jr.
Exploring Our Dynamic Planet consists of interactive tools, curriculum, and background materials that enable students to better visualize geophysical and geological processes and structures. A classroom module explores plate tectonics using geodesy results from GPS to observe and measure crustal motion. Tools include Jules Verne Voyager, Jr., which allows students to choose from a variety of base maps, add a number of geographic and geophysical overlays (e.g. plate boundaries, earthquake and volcano locations), and then superimpose crustal motion velocity vectors to observe how the tectonic plates move in relation to one another. The tool can be used to explore topics such as plate tectonics, seafloor spreading, and seasonal land and ocean productivity.
The PLATES Project
This is the web page for PLATES, a program of research into plate tectonic and geologic reconstructions at the University of Texas at Austin Institute for Geophysics. The page contains links to a brief overview of plate tectonics and plate reconstructions using the PLATES Project's global plate reconstruction model, in addition to movies in the format of powerpoint animations which can be downloaded for later use. Models are shown on the evolution of the earth's oceans and the movement of the earth's tectonic plates from the Late Precambrian through the present day, reconstructing (i.e. "predicting") geological environments through geologic history. Maps of the following can be accessed: late Neo-Proterozoic, Silurian, early Jurassic, early Cretaceous, Cretaceous-Tertiary Boundary, and Oligocene. Movies are available on the following subjects: global plate motion, Jurassic to present day, opening of the Indian Ocean, and tectonic evolution of the Arctic region.
This Dynamic Earth: the Story of Plate Tectonics
This publication provides an introduction to the theory of plate tectonics. It was intended as a companion to the map entitled 'This Dynamic Planet', published by the U.S. Geological Survey (USGS) and the Smithsonian Institution. Topics include the history and development of the theory, lines of evidence, plate motions and interactions, hotspots, what drives plate motion, and extraterrestrial plate tectonics. It can be viewed online, downloaded, or purchased in hardcopy. Ordering information is provided.
Monterey Canyon Turbidity Flow
This website describes two turbidity events flowing down Monterey Canyon. The flows were recorded in December 2002 by a benthic mooring device located at1300 m depth. The website contains a detailed description of the events as well as graphs and illustrations of the effect of the event on instrumentation, including parameters such as flow speed and temperature.
The fluid dynamics of natural turbidity currents, Lillooet Lake, British Columbia, Canada
This website describes the outcome of two field studies at the University of Leeds, that examined the dynamics of density currents generated by river inflow into Lillooet Lake. This website presents the background to the study, details of the methodology as well as photographs and graphical representations of the findings. The study provides the first dataset from natural sediment-laden turbidity currents and bridges the gap between natural currents and laboratory and numerical simulations.
This website provides information and photographs of current laboratory models of turbidity currents. Photographs include pictures of the flume and the movement of turbidity currents in that flume.
Essentials of Geology: Hot Spot Volcanoes Animation
This animation, listed as 2.10 in Chapter Two in the Essentials of Geology web page, shows how hot spot volcanoes arise. Users may access this and many other animations describing plate tectonic processes from the Chapter Two webpage. Users may also follow links to other chapters in the Essentials of Geology book.
