The Science Support Program was designed to explore marine geosciences and Earth’s environment and history.
Multiple drilling expeditions are made through the ocean for research.
They are basically exploring the oceans, looking for whatever may be an interest to the scientific community.
From climate, possible fossils, minerals, energy, resources, soil, ocean, freshwater, weather, atmosphere, environmental chemistry, biology and anything that might expand our knowledge regarding our history.
Think of it as marine geology.
This is a beautiful career to learn, and it can be very beneficial to the world. If this is something that interests you, I encourage you to do more research; you can start with their website.
