This news article examines how scientists are looking at sites on Earth, especially Mono Lake in central California, to see how evidence of past life on Mars might be preserved. A selection of links to related topics is provided. Full description.

This document provides an extensive description of a strategy to deliver credible predictions of future atmospheric carbon dioxide levels based on improved understanding of dynamics in the Earth's carbon reservoirs (the land, air and oceans). Full description.

This article explains how the TOPEX/Poseidon satellite has been used to measure changes in sea level due to heat storage in the ocean. The satellite is able to measure and compensate for the effects of solar and lunar tides so that the data can be used for the study of ocean circulation. Full description.

This article explains how the TOPEX/Poseidon satellite has been used to track large-scale ocean waves called Rossby waves. This new data indicates that the waves may move faster than previously thought, which may have implications for global weather forecasting. Links to related sites are provided. Full description.

This tutorial provides a basic discussion about crystallography. Text and diagrams explain how crystals are measured, classified, and described, and point out that minerals can be identified by their crystal shapes and growth habits. Full description.

This resource presents basic information about how the TOPEX/Poseidon satellite works, what factors affect ocean topography and how ocean circulation affects the Earth's climate. Remote imagery, diagrams, and links to related topics are included. Full description.
