1. Introduction

As mentioned in Chapters 19 and 20, regions to the deep ocean and the ocean
the ocean is an interactive part of the floor, knowledge about the state of the
entire Earth system. The ocean is charac- ocean and its behavior is increasingly nec-
terized by its dynamic physical and bio- essary for society; the Blue Economy is per-
geochemical processes with variability at manently imposing the growth of its ac-
all scales of space and time. Ocean circu- tivities on the ocean, from the surface to
lation transports and mixes, on a global the bottom. Observing the ocean becomes
scale, heat and water masses with various crucial but challenges are imposed by the
chemical contents. Any natural or artificial size of the ocean and the myriad of pro-
material that pollutes oceanic regions can cesses that there occur in all scales. Since

through human activities are impacted by nerships. However, the Global Ocean Ob-
