Upper ocean temperature change

WaterOceans & Seas

This quantity is a single measurement of the quantity at a given point in time (2015).

Value:

This is equivalent to...

0.34 ± 0.06 °F

HuID: 69674
Relevant Year(s): 2015
Summary: Temperature increase of the upper 700 m of the ocean relative to the average temperature during reference years 1958-1962.
Method: This temperature increase is computed from the ocean heat uptake in the upper 700 m of the ocean, using the density and specific heat of seawater, as well as the surface area of the ocean. Ocean heat uptake trend for 0-700 m reported in Table S1 (supplementary information) of the article. The uncertainty reported is the 95% confidence interval of the temperature change with respect to the reference temperature (average temperature during pentadal period 1958-1962) rounded to one significant figure.
