Perhaps the most important observation is that oceanography gives you a world view, an understanding, of the global system that is our environment, which can inspire your work, wherever it leads. Today, we still need to bring back samples of water from the deep ocean for analysis, but many of our measurements are now electronic; and there are many more things we can measure. Physical variables like temperature and salinity are observed in this way, and there are new probes being designed that will allow electronic measurement of many chemical and biological variables.
