North Sea Atlas
Temperature, Salinity, Density and Heat Content
Monthly means for the period 1902 to 1954
Preface
This atlas is based on two publications.
1. G. Tomczak und E. Goedecke
'Die thermische Schichtung der Nordsee auf Grund des mittleren Jahresganges der
Temperatur in 1/2°- und 1 “-Feldern', (DHZ 1964, Ergänzungsheft Reihe B, Nr. 8).
The temperature figures of Tomczak and Goedecke represent mean monthly vertical sections and
horizontal charts of the North Sea, based on 122151 temperature data of the years 1902 to 1954
Accuracy of the monthly mean values:
Total:
+/- 0.9
Bottom:
+/- 0.8
Areas of shallow water:
Surface:
+/- 1.2
Bottom:
+/- 1.2
Areas of deeper water:
Surface:
+/- 0.8
Bottom:
+/- 0.6
Absolut highest differences of single years from the mean values: +4.6 K and -5.3 K.
For more details see tabel 1 and 2 of their publication.
2. Erich Goedecke, Jens Smed und Gerhard Tomczak
'Monatskarten des Salzgehaltes der Nordsee dargestellt für verschiedene
Tiefenhorizonte', (DHZ 1967, Ergänzungsheft Reihe B, Nr. 9).
The mean monthly salinity charts for the depth layers 7,5m, 20m, 30m, 40m, 60m, 80m, 100m and
the bottom were analysed from 146287 data of the years 1902 to 1954.
Accuracy of the monthly mean values:
zonal
at 59.5°N:
Surface:
+/- 0.2 bis 0.4
Bottom:
+/-0.1
meridional
at 2°E:
Surface:
+/- 0.2 bis 0.3
Bottom:
+/-0.1
Accuracy of the yearly mean values:
zonal
at 59.5°N:
Surface:
+/- 0.2 bis 0.8
Bottom:
+/- 0.2
meridional
at 2°E:
Surface:
+/- 0.2 bis 0.4
Bottom:
+/- 0.2 bis 0.3
For more details see tabel 3 and figures 1 and 2 of their publication.
