In this video adapted from Alaska Sea Grant, discover why multiple tsunamis resulted from the Great Alaska Earthquake of 1964.

What would happen if a portion of the Antarctic Ice Sheet were to melt? This video segment adapted from NOVA uses animations to show the effect of a 6-meter sea-level rise on coastal cities across the world.

This video segment adapted from NOVA uses microwave images to reveal how sea ice doubles the size of Antarctica each winter. Rare footage shows how sea ice crushed the famous ship Endurance in 1914.

This activity proposes different small experiments and discussions to show that in the summer it is cooler by the sea than on the land and that water cools off more slowly than soil.

In this video segment, ZOOM guest Cassie takes us on a tour of the coral reef near her home in Key Largo, Florida, and points out some of its unique features.

This video segment adapted from NASA's Goddard Space Flight Center describes El NiŰ__ŒóíŠo, how it forms, and the chain reaction of consequences it triggers around the globe.

Learn about the different features of snow and ice in Antarctica using satellite imagery in this video segment adapted from NASA.

The marine environment is unique and because little light penetrates under water, technologies that use sound are required to gather information. The seafloor is characterized using underwater sound and acoustical systems. Current technological innovations enable scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles enables researchers to map and understand the sea floor. Similar technologies also aid in animal tracking, a method used within science and commercial industries. Through inquiry-based learning techniques, students learn the importance of habitat mapping and animal tracking.

A career with NOAA could launch you all over the world, from the warm waters of the Caribbean to the winter wonders of the South Pole. The challenges are endless. Employment in NOAA is a job with a mission. At NOAA, safeguarding the public, protecting natural resources, strengthening the economy. It's all in a day's work. Imagine yourself. Careers in NOAA are as diverse as the line offices that make up the agency. More information can be found on the Office of Workforce Management website.

This video segment adapted from NOVA follows the clean-up effort after the 1989 Exxon Valdez oil spill off the coast of Alaska. Also featured is a marsh where an oil spill occurred 20 years earlier; analysis suggests that environmental damage may last for decades.

In this activity, students learn about ocean currents and the difference between salt and fresh water. They use colored ice cubes to see how cold and warm water mix and how this mixing causes currents. Also, students learn how surface currents occur due to wind streams. Lastly, they learn how fresh water floats on top of salt water, the difference between water in the ocean and fresh water throughout the planet, and how engineers are involved in the design of ocean water systems for human use.

Students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches the continental shelf. Students make villages of model houses and buildings to test how different material types are impacted by the huge waves. They further discuss how engineers design buildings to survive tsunamis. Much of this activity setup is the same as for the Mini-Landscape activity in Lesson 4 of the Natural Disasters unit.

This illustrated essay from the NOVA Web site answers questions about irregularities in the tides.

The Virgin Islands Marine Advisory Service (VIMAS) aims to increase awareness about marine and terrestrial natural resources as well as help foster environmental stewardship ethics within the Virgin Islands' community.
