Hydrographic CTD data from 1993 to 2016 in the East Sea (Japan Sea) through 19 cruise surveys supported by CREAMS or EAST-I programs.

Using highly accurate conductivity-temperature-depth (CTD) instruments, 922 profiles of water temperature and salinity were collected in a semi-enclosed miniature ocean, the East Sea (Japan Sea), through total 19 international joint surveys between 1993­ ­and 2016 as part of the Circulation Research of the East Asian Marginal Seas program and with supports from the East Asian Seas Time-series I project
