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 ...

The site focuses on the responses of Antarctica and its sea ice to climate changes. Two experiments help illustrate what happens as water warms and how this warming could affect sea levels and low-lying coastal areas. Links to more detailed information are also provided. Full description.

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.

This description of the El Nino pattern in the eastern Pacific is from NASA's Earth Science Enterprise. In addition to text and diagrams, it provides three weather related activities for lab or classroom. Full description.

This NASA site contains a wealth of information about hurricanes, including how they are created, how they move, and the dangers they pose. Also included are sections that deal with naming of hurricanes, hurricane hunters, a VR trip through a hurricane, satellite instrumentation, and a video of hurricane Andrew. Full description.

This lesson plan provides instruction to teachers for creating a glacier in the classroom to demonstrate how glaciation affects landforms. Learning objectives include student understanding that as glaciers move, they create a variety of patterns on landforms by a process called glacial scraping, that the scraping patterns left by a glacier depend on how the glacier moved over the landform, and 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.

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.

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.
