HOW CAN WE MEASURE THE OCEAN?
There are many different ways to collect ocean data, and generally the method is chosen depending on what one wants to measure and how much money one has. I've split the main measuring platforms that are used into three main sections:
1. Marine robotic vehicles
useful for 3D studies, i.e. for phenomena that spread both vertically and horizontally, like oil spills or animal migrations
2. Surface and profiling instruments
useful for 1D or 2D studies, especially long-term, like how oxygen varies with depth in a specific location
3. Other fundamental methods
ships, submarines, and satellites: these methods show the progression of research platforms throughout history
It is very probable that some people will disagree with how I've categorized marine vehicles. The lines between the different types are still fairly blurred and there is no universal agreement. Below is a general overview of vehicle types as well as a more detailed look at naming differences.
