Observing Salinity Patterns part of Cutting Edge:Oceanography:Activities
Part 1: Students measure the salinity of samples using a refractometer, and consider the units and density of these values. Part 2: Students apply concepts and reinforce what they've learned about salinity and the water cycle to interpret a salinity contour map of a transect of the Pacific Ocean using WOCE data. Another goal is to familiarize students with using contour graphs of ocean data, in general.
Waves and Tides: Understanding Characteristics & Practice Problems part of Cutting Edge:Oceanography:Activities
Part A: Students identify basic characteristics and terminology for waves. Part B: Students define factors that influence tides and practice using tide charts and tide tables.
