Popular & Trade vs. Peer-Reviewed

What is the difference between these 2 publications?

Oceanography and National Geographic journal covers   

They both come out once every month, are published in the United States, and are "factual".They both have pictures. They even cover some of the same topics.

The difference is that one--Oceanography--is peer-reviewed, whereas National Geographic is a popular-press title. 

Peer review is scientists' and other scholars' best effort to publish truthful, reliable information. Each article has been submitted for publication, but then reviewed by other scholars in the same field to ensure that it is sound science. Among other things, peer-review checks to make sure that a scientist's methodology is fully described (how he or she got their results) and that there aren't obvious errors of statistical calculation.

Peer-reviewed journals are generally considered "primary source" material: When a new scientific discovery is made, a peer-reviewed journal is often--but not always--the first place it appears.

Popular and trade publications are not peer-reviewed, they are simply edited. That does not mean they are any less potentially truthful or informative--most popular and trade publications take pride in careful fact-checking.* But when the topic is scientific research, the information is generally "secondary": It has already appeared elsewhere (usually in a peer-reviewed journal) and has now been "digested" for a broader audience.
