Mars Odyssey Epithermal Neutron Data overlayed on MGS-MOLA Topography Data (Full Globe, Viking True
Mars Odysseys Gamma-ray spectrometer (GRS) instrument has detected large amounts of Hydrogen on Mars, particularly near the south pole. This is an indication that water ice exists in the upper meter of these areas of the Martian surface. The epithermal neutron data ranges from 0 to about 12 counts per ...
FUSE-MOLA: Mars Once Had Oceans
This visualization shows how Mars might look with an ocean at -500m where the lowest point on Mars is about -8000m and the highest point is about 22000m. Data from The FUSE spacecraft and from the Mars Global Surveyor-MOLA instrument where used to support this theory.
AURA-OMI Tropospheric Ozone over South America
Auras instruments study tropospheric, or low-level atmospheric chemistry. Many different organizations monitor regional areas of the troposphere, but Aura is the first to record daily global measurements.
Ocean Tides Lost and Found
The Moon's gravity imparts tremendous energy to the Earth, raising tides throughout the global oceans. What happens to all this energy? Scientists studying data from the orbiting TOPEX/Poseidon satellite believe they now have an answer. Users can read about the tidal energy imparted upon the earth by ...
Mapping the Watery Hills and Dales
This classroom activity explains and demonstrates how the Global Positioning System satellites work to provide precise location information to positions on the ground, as well as to other satellites whose job is to map the surface of Earth. The activity is specifically tied to NASA's Jason-1 and Topex/Poseidon ...
Total Ozone Mapping Spectrometer
Visitors can access near-realtime measurements of ozone in the atmosphere. A full global image can be selected, or today's measurements, or ozone data over any chosen location. Archived measurements are available as far back as November 1978, and a link to an online textbook about stratospheric ozone ...
This activity has students create a Cartesian diver, which will act in some ways like a submarine. Students will adjust the amount of air and water in an inverted test tube (the "diver") so that it at first barely floats in a water-filled bottle. Then, they will squeeze the closed bottle to create higher water pressure, causing the diver to sink. Releasing the bottle allows the diver to float again. Written instructions, a list of materials, and illustrations are included.
Ocean Surface Topography from Space
The "Global Conveyor Belt" shows how the oceans move energy from the tropics to the poles and back again in order to moderate Earth's climate. This is accomplished through long-term ocean circulation. This on-line tutorial about ocean circulation features text, pictures, and satellite imagery with links ...
Mississippi River Sediment Plume
This satellite image shows the brown sediment-laden water of the Mississippi River mixing wih the dark blue water of the Gulf of Mexico following a rainstorm. The city of New Orleans and Lake Ponchartrain can easily be discerned near the center of the image.
Precipitation Data and Information Services Center
This site contains several sets of precipitation data from NASA Goddard Space Flight Center. Data sources include the Tropical Rainfall Measuring Mission, global precipitation data, and hydrology field experiments. Data sets include real time, monthly or daily global precipitation analyses, precipitation ...
How does the temperature of the Great Lakes change over time?
This classroom activity allows students to use water surface temperature, bathymetric data and weather data to look at trends in the water temperature of the Great Lakes. The exercise asks students to make predictions, and then use the data to answer questions. The site contains everything that is needed ...
US Global Change Research Program
This site contains a variety of information related to global change research and specifically the research efforts of the US Global Change Research Program (USGCRP). Some of the sections on this site include global change data from a variety of government agencies as well as reports from national and ...
US National Assessment of the Potential Consequences of Climate Variability and Change
The United States Global Change Research Program (USGCRP) was created as a high-priority national research program to: address key uncertainties about changes in the Earth's global environmental system, both natural and human-induced; monitor, understand, and predict global change; and provide a sound ...
WEB-PHREEQ: Aqueous Geochemical Modeling
WEB-PHREEQ is a web-based computer application for aqueous geochemical modeling. WEB-PHREEQ was developed for classroom teaching and for routine calculation of the distribution of chemical species in water. Users can calculate the effects of mixing of waters, adding phases to the solution, or changing ...
"Electromagnetic Field Theory: A Problem Solving Approach, Spring 2008"
" This text is an introductory treatment on the junior level for a two-semester electrical engineering course starting from the Coulomb-Lorentz force law on a point charge. The theory is extended by the continuous superposition of solutions from previously developed simpler problems leading to the general integral and differential field laws. Often the same problem is solved by different methods so that the advantages and limitations of each approach becomes clear. Sample problems and their solu
"Electromechanical Dynamics, Spring 2009"
" First published in 1968 by John Wiley and Sons, Inc., Electromechanical Dynamics discusses the interaction of electromagnetic fields with media in motion. The subject combines classical mechanics and electromagnetic theory and provides opportunities to develop physical intuition. The book uses examples that emphasize the connections between physical reality and analytical models. Types of electromechanical interactions covered include rotating machinery, plasma dynamics, the electromechanics o
"Global Enterprise for Micro-Mechanics and Molecular Medicine (GEM4), Summer 2006"
"GEM4 VisionGEM4 has brought together researchers and professionals in major institutions across the globe with distinctly different, but complementary, expertise and facilities to address significant problems at the intersections of select topics of engineering, life sciences, technology, medicine and public health.GEM4 creates new models for interactions across scientific disciplinary boundaries whereby problems spanning the range of fundamental science to clinical studies and public health ca
The carbon cycle: what goes around comes around
Resources provided in this publication will allow you to facilitate your students’ application of carbon, carbon compounds, and carbon cycle knowledge to real environmental issues. In this way they apply knowledge, analyze issues, synthesize concepts, and evaluate proposed solutions.
Turbidity and TSS
This image-rich Streams.org website describes turbidity and total suspended solids (TSS). It includes overviews about what they are, why they are measured, how they are measured, and why they vary. The site also features links to sensor and other water quality parameters.
