Webinar Clip
In this clip, Dr. Lindstrom gives viewers a comparison between early seagoing vessels and earth-observing satellites using the HMS Challenger and the International Space Station as examples. He then describes the kinds of information we can obtain from space: images, measurements, and data as well as more accurate weather models. We've "taken oceanography from ships to space!" To continue this thread, he then goes on to showcase the Aquarius/SAC-D satellite and the various technology onboard.

Applicable Science Standards
  • Planning and Carrying Out Investigations Planning and Carrying Out Investigations. Scientists and engineers plan and carry out investigations in the field or laboratory, working collaboratively as well as individually. Their investigations are systematic and require clarifying what counts as data and identifying variables or parameters.
  • Obtaining, Evaluating, and Communicating Information Obtaining, Evaluating, and Communicating Information. Scientists and engineers must be able to communicate clearly and persuasively the ideas and methods they generate. Critiquing and communicating ideas individually and in groups is a critical professional activity.
