Ocean observing is an all encompassing term that can mean many different things to each reader.  There are an infinite number of ways of observing the ocean, depending on how creative you are at defining “observe.”  When scientists discuss the topic, there is an established set of technology and meaning attached to the term "ocean observing."  But when teaching students about these topics, there are many other topics included within the phrase that are often left untouched.   
 
Merriam-Webster defines "observe" as follows:

"verb, a: to watch carefully especially with attention to details or behavior for the purpose of arriving at a judgment b: to make a scientific observation on or of c: to come to realize or know especially through consideration of noted facts.” 

To the right is a list that includes examples of how you can be an ocean observer by studying ocean related topics, integrating real time data, and finding ways to collect your own data based on your own questions.
