From Sailing Ships to Satellite: Studying Salinity Through A Sensor Web
What is a sensor web, and how does it help SPURS? Dr. Eric Lindstrom takes us on a trip through salinity research, revealing how ocean exploration has evolved over time. The SPURS team took part in an international collaborative effort to better understand this fundamental part of the ocean and climate system, and used a combination of approaches to investigate what's happening in the unique "ocean desert" of the North Atlantic.

Applicable Next Generation Science Standards
  • Influence of Engineering, Technology, and Science on Society and the Natural World Crosscutting Concept: New technologies can have deep impacts on society and the environment, including some that were not anticipated. Analysis of costs and benefits is a critical aspect of decisions about technology (HS-ESS2-2).
    • [HS-ESS2-2] Analyze geoscience data to make the claim that one change to Earth's surface can create feedbacks that cause changes to other Earth's systems.
  • Interdependence of Science, Engineering, and Technology Crosscutting Concept: Scientific discoveries about the natural world can often lead to new and improved technologies, which are developed through the engineering design process (3-PS2-4).
    • [3-PS2-4] Define a simple design problem that can be solved by applying scientific ideas about magnets.
