Hurricanes are the most powerful weather event on Earth. NASA’s expertise in space and scientific exploration contributes to essential services provided to the American people by other federal agencies, such as hurricane weather forecasting.

Background information on the El Nino Southern Oscillation or ENSO.

GLOBE protocols and learning activities that complement the Sea Level Change phenomenon are outlined.

In this experiment, students make a claim about the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents.  This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.

Explore and connect to hydrosphere protocols in GLOBE. Each protocol has related Earth System Data Explorer datasets identified as well.

Explore the energy and matter cycles found within the Earth System. 

Discover how GLOBE hydrosphere protocols and learning activities can provide hands-on opportunities for students to explore My NASA Data hydrosphere phenomena.

In this activity, students will learn about sea ice and land ice. They will observe ice melting on a solid surface near a body of water and ice melting in a body of water.

This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.

NASA Earth Observations (NEO) strives to make global satellite imagery as accessible as possible. Here you can browse and download imagery of satellite data from NASA's constellation of Earth Observing System satellites.
