I. Background
Today, we will cover four layers (2,3,14, and 15), leaving the remaining four layers (0,1,16, and 17) for next time.
Then, we will have covered the Earth's entire ocean surface, and its depths, in this series (The Layered Approach To Big Water, 2, 3, 4).
In general, some of the big water layers covered today have more gyrations than those covered so far, because the closer we get to the poles the more the great ice sheets and glacial fields have a visible, measurable impact on ocean temperatures, salinity, sea level, and currents.

The changes associated with global warming impact not only the atmosphere and biosphere, they also impact on the oceans andthe cryosphere.

III. Today's Layers

Over the years scientists have dutifully collected this information before there was a significant knowledge and scientific consensus of global warming.
We are granted a peak at the results of their hard work, and at no cost to us (except for the time to peruse it).

"NOTICE: these values are NOT temperatures, they are CHANGES IN TEMPERATURE:
Combined averages for 36 total WOD Zones
(values are in deg. C)
Concerning change, the mean average was 94 upward & 74 downward changes.
Average changes per depth level were:
- 0-200m = 0.307199
- 200-400m = -0.0361685
- 400-600m = 0.0603223
- 600-800m = -0.104663
- 800-1000m = -0.0230397
- 1000-3000m = -0.0101448
- >3000m = -0.0157178
Years involved: 1956 -> 2016 (60 yrs)
Average annual combined change:
- (0.177787 ÷ 60): 0.00296312 C per year"

But, when we come to Layer Two (Fig. 4a, Fig. 4b), the momentum switches the other way once again.
Fig. 5b |
Layer Two is impacted by the Glacier Bay glacial field area of Southeast Alaska, and the Greenland Ice Sheet impact on Scandinavia (Proof of Concept - 3, 5).
The stark sea level fall in those areas is in contrast with the positive temperature increases in the zones of Layer Two:
"NOTICE: these values are NOT temperatures, they are CHANGES IN TEMPERATURE:
Combined averages for 24 total WOD Zones
(values are in deg. C)
Concerning change, the mean average
was 48 upward & 46 downward changes.
Average changes per depth level were:
- 0-200m = 0.554762
- 200-400m = -0.361864
- 400-600m = -0.743106
- 600-800m = 0.079645
- 800-1000m = -0.206903
- 1000-3000m = -0.112317
- >3000m = 0.0393799
Years involved: 1971 -> 2016 (45 yrs)
Average annual combined change:
- (-0.750403 ÷ 45): -0.0166756 C per year"
That would be an argument for thermal contraction, not thermal expansion.
The same thing can be said if we consider the final layer, Layer Fifteen (Fig. 5a, Fig. 5b).
It supports a thermal expansion / thermal contraction scenario, not an exclusive expansion:
"NOTICE: these values are NOT temperatures, they are CHANGES IN TEMPERATURE:
Combined averages for 36 total WOD Zones
(values are in deg. C)
Concerning change, the mean average
was 68 upward & 68 downward changes.
Average changes per depth level were:
- 0-200m = -0.179962
- 200-400m = 0.123373
- 400-600m = 0.0333803
- 600-800m = 0.128745
- 800-1000m = 0.141013
- 1000-3000m = -0.0721937
- >3000m = 0.040435
Years involved: 1956 -> 2016 (60 yrs)
Average annual combined change:
- (0.21479 ÷ 60): 0.00357983 C per year
The temperature analysis shows an overall temperature increase of 0.00357983 C per year for 60 years, for a total increase of 0.21479 degrees C.
Yet the sea level is falling lately, probably because it is not far from Antarctica.
IV. Conclusion
Today's analysis, combined with the analysis of other layers considered in previous posts, where there should have been conclusive proof of thermal expansion as the main cause of sea level rise, but wasn't, I remain skeptical (On Thermal Expansion & Thermal Contraction - 13).
That, combined with the clear proof of cryosphere disintegration and melting, renders the situation such that I can't buy the "thermal expansion is the main cause of sea level rise in the 19th and 20th centuries" hypothesis.
But we still have 4 layers to go (arctic and antarctic layers).
Stay tuned.
