The Internationally-Operated 'Argo' Ocean Measurement System Confirms Significant Cooling of Major Ocean Areas
Read here. The 'Argo' ocean buoy real-time reporting system is the most advanced technology that scientists possess for measuring ocean temperatures at varying levels. Recently, NASA scientists at its Jet Propulsion Lab reported that the Argo data was showing a slight ocean cooling trend since 2003, which was recently confirmed by another peer-reviewed paper.
This ocean cooling has proven to be a major source of embarrassment to AGW scientists as it is the exact opposite of what they and the IPCC climate models predicted.
Now, a new paper by Vélez-Belchí et al. finds that Argo data indicates significant ocean cooling in the Mid-Atlantic area since 1998.
"An analysis of the five oceanographic cruises at this latitude shows that there has been a significant cooling of −0.15°C in the upper ocean (600–1800-dbar range) over the last 7 years, from 1998 to 2004, which is in contrast to the warming of 0.27°C observed from 1957 to 1998. Salinity shows a similar change in tendency, with freshening since 1998. For the upper ocean at 24.5°N, 1998 was the warmest and saltiest year since 1957. Data from the Argo network are used to corroborate the strong cooling and freshening since 1998..."[Vélez-Belchí, Pedro, Alonso Hernández-Guerra, Eugenio Fraile-Nuez, Verónica Benítez-Barrios, 2010: Journal of Physical Oceanography]
"According to climate scientist Roger Pielke Sr, ocean heat content provides the most appropriate metric to diagnose global warming, rather than the conventional use of ground and atmospheric temperatures."
