Can you tell El Nino from La Nina? This interactive was created by UCAR Center for Science Education using satellite images of the height of the ocean surface. Students interpret these images to identify whether they represent El Nino, La Nina, or neither event (La Nada!).
Information from satellites if often used to display information about objects. This information can include how things appear, as well as their contents. Explore how pixel data sequences can be used to create an image and interpret it.
Sea surface temperature is a measure of the temperature of the very top layer of water. Scientists are not able to put a thermometer into every part of the ocean on Earth to measure its temperature.
Students analyze the relationship between sea surface topography and ocean surface currents by graphing sea height differences using data collected from NASA's TOPEX/Poseidon mission.
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.
