Visitors can find answers to frequently asked questions regarding sea level and sea level changes. Topics addressed include how mean sea level is defined, how much sea level would rise if all the world's ice were to melt, differences in sea level between oceans and at different latitudes, the meaning of altitude above sea level, and others.

The International Ice Patrol is a branch of the United States Coast Guard. They monitor iceberg danger near the Grand Banks of Newfoundland, and provide the limits of all known ice to the maritime community. This kids page provides an illustrated story of the life cycle of icebergs, as well as a list of questions and answers about icebergs in general. There is also a set of links to other sites that ...

This activity guide explores the potential for global climate change to increase the frequency and intensity of hurricanes and storm surges, and the impacts that could result. Designed to teach through scientific inquiry, the activity seeks to stimulate thought about the long-term impact of a warmer planet. The activity responds to national education standards in the English language arts, geography, ... Full description.

This site provides information on the many aspects of the study of the sea surface from space. Measuring the ocean surface topography provides information for studying global ocean circulation and the oceans heat budget. Regular scanning of the ocean surface to maintain a database of ocean surface topography can help predict short-term changes in weather and longer-term patterns of climate. Educational ...

Use real-time data to investigate the driving forces behind the Gulf Stream, learn how it affects the Atlantic Ocean, and explore how it affects mankind on a daily basis. This website provides classroom activities in science, math, history and language arts. Use the material as a complete tutorial, or use pieces individually to supplement traditional classroom lessons. Many external links that provide ... Full description.

Scientists have studied the physical properties of clouds and have developed instruments onboard satellites to characterize the types of clouds they see below. Some satellites have instruments that allow them to measure rainfall as well. For this lesson, students will hypothesize what types of clouds they believe will create the most precipitation (rainfall) over Nashville, TN. Students use the Live ... Full description.

One of the most studied and important ocean currents of the world lies along the eastern coast of the United States and is called the Gulf Stream. It derives its name from its source region of warm water in the Gulf of Mexico. For the past two decades, scientists have been collecting sea surface temperature (SST) data from satellites, buoys and ships in the Gulf Stream and Atlantic Basin. In this ... Full description.

This lesson is designed to help students gain knowledge in accessing current weather data and in using the MY NASA DATA Live Access Server (LAS) to specify and download historical satellite data. Students then use the data to examine the relationship between altitude, atmospheric pressure, temperature and humidity at a particular location. In this lesson, weather data from ground-based and satellite ... Full description.

Corals feed on algae that thrive in the sunlit water surrounding a reef. However, when water temperatures get too warm, the algae food source dies and corals turn a whitish color. Through scientific observation, it has been determined that coral bleaching may occur when sea surface temperature (SST) exceeds 30C or 86F for a week or longer. During late 2005, a major coral bleaching event occurred when ... Full description.

Watersheds are those land areas that catch rain or snow and drain to specific marshes, streams, rivers, lakes, or to ground water. This site allows users to locate their watershed by city, county, state, or region. Links provide information about stream flow, water use, conservation efforts, demographics, forest riparian habitats, science in your watershed, water discharges, and assessment of watershed ...
