A dataset of profile observation on three-anchor buoy integrated observation platform of the East China Observation station in 2018–2019

Ocean profile observation is an important link to realize "transparent ocean" observation to the ocean at full scale. The East China Sea Ocean Observation and Research Station developed the three-anchor buoy integrated observation platform with a diameter of 15 meters，which can realize the real-time observation of sea surface meteorology - underwater shallow water quality and hydrology - underwater profile environment. The area (30°27 '32.6 "N, 120°14' 25.22" E) has been continuously observed for 14 months and valuable real-time continuous observation data have been obtained in this area. The dataset collated the profile data. In order to make better use these observation data, we adopt standard data processing methods and quality control system to process and control these profile observation data. It provides a key link for the establishment of a full-scale observation system covering oceanic atmosphere, oceanic surface layer, water profile and seabed, and provides richer and more complete data support for basic research of Marine science and disaster prevention and reduction in China.
