Abstract: Obama's administration unveiled the "Big Data Research and Development Initiative" suggesting that big data technological breakthrough in basic scientific research fields will be the focus of future development. In the big data era, marine geo-information construction should get rid of the valuation based simply on data amount and pay more attention to the service value of data information. Meanwhile,drawing on big data thinking,information construction should explore data mining and visualization techniques to enhance the data insight abilities and to make the value of marine geology data maximized.
