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.

Crystal Growth Movies (title enhanced by cataloger)

This site, maintained by the Department of Geology and Geophysics at the University of Wyoming, contains four QuickTime videos of actual crystal growth. To access the videos, scroll down to the bottom of the page and click on any of the downloads that are available. These videos enhance understanding of the processes involved in crystallization.

Alan L. Jones Computer Programs: Seismic/Eruption

This site is the homepage of Alan L. Jones, of the State University of New York at Binghamton. Dr. Jones is interested in most earthquake-related topics, computer graphics, and computers in education. He has created various computer-based visualizations: Seismic/Eruption, Seismic Waves, AmaSeis, and Eqlocate. Seismic/Eruption is a program used to visualize seismicity and volcanic activity in space and time. The program displays earthquakes and volcanoes (data from the Smithsonian Institution Global Volcanism Program) and can show seismicity beneath the earth in three-dimensional and cross-sectional views. Programs can be downloaded from this page.

Why Topography?

Part of the supporting resources for the School of Earth Sciences dynamic earth module, the -Why Topography?- site discusses two models introduced in the 19th century that are still used to explain topographic variations. These models are the Pratt and Airy models of isostasy. In the Pratt model, high topography (relative to surroundings) is due to lower density whereas in the Airy model, high topography is due to thick crust.

NOAA Photo Library: America's Coastlines

America has 95,000 miles of coastline. In this collection of images from NOAA, the user can view images of America's coasts and adjacent coastal regions. Images include early Nineteenth Century sketches and drawings and modern photographs of waves, rocky shores, sandy beaches, marshes, mangroves, seaside villages, and port cities.

National Oceanic and Atmospheric Administration: Paleoclimatology Program

The National Oceanic and Atmospheric Administration's (NOAA) Paleoclimatology Program, located at the National Geophysical Data Center (NGDC), helps the world share scientific data and information related to climate system variability and predictability. Their mission is to ensure the international paleoclimate research community meets the scientific goals of programs including the International Geosphere-Biosphere Programme PAGES (IGBP PAGES) and the World Climate Research Programme on Climate Variability and Predictability (WCRP CLIVAR). This site includes a section on Research Programs, including information on the scientific goals, reports and publications, extramural program, and scientific conferences. An Education and Outreach section provides background on paleoclimatology as a discipline, paleoclimatology slide sets, information specific to primary and secondary educators, and links to other paleoclimate education programs, including NOAA's own (GLOBE). The Paleoclimate Data section assists users in both data access and submission. Data are available for the following subdisciplines: borehole data, climate forcing, corals, fauna, ice cores, insects, paleoclimate modeling, paleolimnology, paleooceanography, plant macrofossils, pollen, tree ring, and other paleo data. Alternatively, searches for subsets of data can be conducted within all available paleoclimatology data, global climate modeling (GCM) boundary conditions, paleocean data, paleoclimate model output, pollen data, or tree ring data. Other site features include a What's New section, Paleo Perspectives, a general link list (Places of Interest), a Paleo Visitor Program, an Address Exchange and Discussion List, and an area in which to download Free Software useful in paleoclimate research.

Climate TimeLine Information Tool

The Climate TimeLine (CTL) Information Tool summarizes climate history for time spans from 1 year to 100,000 years ago and beyond. The relation between human development, weather, and climate is explored. The CTL explains how past climate is measured, provides basic information on paleoclimatology, and explains the use of paleo proxies. There is a tutorial on drought and how to use the CTL to investigate that topic. There is also a climate glossary and links to climate and paleoclimate data.

Plate Tectonic Animations

This is a collection of thirteen brief plate tectonic animations that were originally produced for the US Geological Survey video Secrets in Stone. They have been converted to animated gifs for web display.

Exploring Earth

Using imagery and visualizations, this site offers investigations of almost every Earth science topic imaginable. It is structured to follow the unit and chapter headings of an Earth science textbook, offering interactive explorations to complement the topics. The scope is extensive, covering dynamic Earth processes, atmospheric science and ocean science.

SeaWiFS: NASA Carbon Cycle Initiative

SeaWifs 3 year data of the pulse of the planet, helps show the Carbon Build up in the air. For this presentation the Scientist wanted to show how the earth reacts to the chemicals in the air.
