Exploring salinity patterns is a great way to better understand the relationships between the water cycle, ocean circulation, and climate. Explore sea surface salinity mapped plots created from the Earth System Data Explorer, paired with questions (and answers) from the Aquarius Mission. Credit: Aquarius Education
The world's ocean is heated at the surface by the sun, and this heating is uneven for many reasons. Earth's rotation, revolution around the sun, and tilt all play a role, as do the wind-driven ocean surface currents.This animation shows the long-term average sea surface temperature, with red and yellow depicting warmer waters and blue depicting colder waters.
Analyze the first of three graphs of historical ocean data in this series; this mini lesson features salinity values using the interactive tool, FlatMap, created by NASA's Aquarius Mission.
