For the InstructorThese student materials complement the Coastal Processes, Hazards and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Module 4: Understanding Sea Level Change
What is sea level?
As can happen in science, seemingly simple ideas like sea level aren't exactly the easiest thing to define. It is a concept that depends on numerous factors that interact to produce a given sea level at a given time at a given location. In general, sea level (and sea level change) depends on things like the shape of the Earth, the rotation of the Earth, variations in Earth's gravitational field, and a host of other factors that will be explored in this module.
The short YouTube video that follows helps explain what sea level is and how sea level is measured today. The video clip was published on Nov. 25, 2013 by minute physics.
The video is well-done but raises questions that might not have been answered. It might be good to re-watch the video to make sure you understand what is being shared; but continue reading this module, and we will see if we can help you with the challenging parts.
You can also take a look at How Sea Level Changes Affect Coastal Planning (NOAA)for more information.
