Explore and connect to the GLOBE Water Cycle protocol bundle. 

Explore and connect to the GLOBE Oceans protocol bundle. 

GLOBE protocols and learning activities that complement the El Niño Southern Oscillation phenomenon through hands-on investigations are detailed.

Explore and connect to the GLOBE Water Quality protocol bundle. 

GLOBE protocols and learning activities that complement the Ocean Circulation Patterns phenomenon through hands-on investigations are detailed. These protocols can be used to build a basis for understanding the principles of salinity and water temperature which are drivers of the ocean circulation patterns.

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

Background information on the El Nino Southern Oscillation or ENSO.

Background information on ocean circulation.

The Earth System Satellite Images help students observe and analyze global Earth and environmental data, understand the relationship among different environmental variables, and explore how the data change seasonally and over longer timescales.
