RIDGE Multibeam Synthesis Project part of SERC Web Resource Collection

An online database of multibeam images and digital terrain models of the ocean floor. Users preview ridge system data by clicking on a map or by selecting from a drop down list. About 15 ridge ...

Images: Visualizing Data part of SERC Web Resource Collection

Available on this site is a host of images, maps, and animations derived from bathymetric and topographic data. Static images and maps include those of estimated seafloor topography from satellite ...

Digital World Tectonic Activity Map (DTAM) part of SERC Web Resource Collection

This visualization tool aids researchers and educators in understanding the tectonic activity of our planet for the past 1 million years. DTAM is a Geographical Information System (GIS) that displays ...

Plate tectonics and the evolution of climate part of SERC Web Resource Collection

Recent work has shown that climate, life, and tectonics interact in ways that are sometimes profound yet not obvious. Norman Sleep reviews two better understood terrestrial examples in this paper. ...

USGS Geophysical Data Products part of SERC Web Resource Collection

This website contains links and listings of digital geophysical products spanning the regional centers of the USGS. There are surveys and reports on magnetic, gravity, and other forms of data. There ...

InSAR: What it is and why you should care part of SERC Web Resource Collection

Provides an overview of what Interferometric Synthetic Aperture Radar (InSAR) is and how it is used to measure surface motion for a variety of geoscience fields. Based on an article originally ...

How does GPS work? part of SERC Web Resource Collection

This document provides a quick explanation of how GPS works, including: (1) errors that need to be considered; (2) how GPS is applied to studying plate tectonics and fault movement; and (3) different ...

GPS data for educators part of SERC Web Resource Collection

Looking for interesting data to use in your course? UNAVCO has worked with educators and scientists to identify GPS stations that illustrate various Earth science processes. The data are the same ...

Elevation correction and the geoid tutorial part of SERC Web Resource Collection

The Earth is not a perfect sphere, but is instead more like a slightly squashed sphere called an ellipsoid. Because of this, GPS receivers must use a correction model (called a geoid) to calculate ...

The geoid and receiver measurements tutorial part of SERC Web Resource Collection

This web page explains how differences in the gravity at different places on Earth requires GPS receivers use additional corrections to find the true elevation of places on Earth's surface. The ...
