Statistics of Water Temperature and Salinity in 1 Degree Mesh


We have calculated statistics for temperature and salinity in the world by using the data of J-DOSS, KODC, and WOD. We provide the statistics values of temperature and salinity, and also provide the atlas which shows the distributions of temperature and salinity by color at the standard depth.
When you choose month, latitude, longitude, and depth, a map will appear on the screen, which contains 11 degree x 11 degree in latitude and longitude around the grid you specify. In each grid, the mean value is shown on the upper row, and the number of samples is shown on the lower row. The maximum and minimum values and the standard deviation at every layer of the grid surrounded by a red frame are shown under the map. The vertical variations of mean values and standard deviations are shown on its right side.

DATA
Total of Used Data : 6.84 million (point observing)
J-DOSS data observed by Japanease research institutes
Observed Year : 1874 -2001
Number of Data : 1.3 million
KODC data
Observed Year : 1961 - 2002
Number of Data : 0.04 millon
WOD2001(World Ocean Databasa 2001) except Observed Japanease and Korea Organizations
Number of Data : 5.5 million
Standard Depth Level
0, 10, 20, 30, 50, 75, 100, 125, 150, 200, 250, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1750, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 5500(m)
Analytical Method
To obtain the value at the standard depth, the profile data are interpolated vertically by using the same method as that of 'WORLD OCEAN DATABASE 2001(NODC)'
Notice
When the number of data in a grid is more than one, the mean value is calculated. Therefore, if the number of data is very small or the observation data are biased, the calculated mean value may possibly differ from the real mean value.
