In order to understand current and future
changes in the ocean system, we need to
understand how it has changed in the past
How have ocean properties (temperature, circulation,
chemistry, basin shape, etc.) changed through time?
Physical Oceanic Resources
Economic commodities present in the
result from deposition, precipitation, or accumulation
of useful substances in the ocean or seabed
ocean crust mineralization
