Ocean Thinking: Changes in Latitude
It may be easy to think about studying the ocean by looking at a small section of it, but the reality is that water is constantly on the move. While highlighting his own research within the SPURS area, Julius Busecke will demonstrate how the atmosphere affects the water cycle both on land and in the ocean, and how the movement of seawater plays a crucial role in our understanding global ocean circulation.

Concept Map: How Does the Atmosphere Affect Land?
This webinar featured a series of three interconnected maps. The first map explores how the atmosphere and land interact, and how there can be desert-like regions both on land and in the ocean. Moving over to the ocean, the second map discusses how the atmosphere's wind, the rotating earth and the ocean surface interact to create the mixed layer and to setup ocean circulation. The final map illustrates the lateral movement of water from the subtropics to the tropics, which affects the salinity in the SPURS research area.

You can explore the first map in the window below, or save it to your own CLIMB account by clicking on the light blue wrench in the upper left corner and selecting Copy Map to My Maps. To view these maps as PDFs click here (PDF, 276 KB).

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.
  • Disciplinary Core Idea: Variations in density due to variations in temperature and salinity drive a global pattern of interconnected ocean currents (MS-ESS2-6).
    • [MS-ESS2-6] Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.
