This activity was developed by NASA's Global Precipitation Measurement (GPM) team as an introductory experience to a series of lessons about water resources on Earth.

 Air, Water, Land, & Life: A Global Perspective

Check out the monthly 2018 images featuring two science variables related to Ocean Circulation: 

• Surface Ocean Current Velocity Vectors (m/s)
• Monthly Near-Surface Wind Vectors (m/s)

This investigation is part of the NASA: Mission Geography Module "What are the causes and consequences of climate change?" that guides students through explorations in climatic variability and evidence for global climate change. 

Background information on soil moisture.

Compare a histogram and map to determine the differences in the information conveyed in each data display.

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

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.

What is the hydrosphere and why is it important?
