Argo, Temperature, and OHC

Guest Post by Willis Eschenbach I’ve been thinking about the Argo floats and the data they’ve collected. There are about 4,000 Argo floats in the ocean. Most of the time they are asleep, a thousand metres below the surface. Every … Continue reading

More on Trenberth’s Missing Heat

In the post Trenberth Still Searching for Missing Heat, we discussed the recent Balmaseda et al (2013) paper “Distinctive climate signals in reanalysis of global ocean heat content”, of which Kevin Trenberth was a coauthor. Dr. Roy Spencer also has … Continue reading

An Ocean of Overconfidence

Guest Post by Willis Eschenbach I previously discussed the question of error bars in oceanic heat content measurements in “Decimals of Precision“. There’s a new study of changes in oceanic heat content, by Levitus et al., called “World Ocean Heat … Continue reading

300 soundings from 19th century compared to Argo data

From the University of California – San Diego Scripps Institute, you gotta love the subheading in this PR. I didn’t know robots could travel back in time. Gosh, I learn something new every day. Apparently 300 soundings done by the HMS Challenger between … Continue reading

Argo Notes the Third

I got into this investigation of Argo because I disbelieved their claimed error of 0.002°C for the annual average temperature of the top mile of the ocean. I discussed this in “Decimals of Precision“, where I showed that the error … Continue reading

Do underwater volcanoes have an effect on ENSO?

I found this post interesting, especially after looking at some of the images that show what appears to be a tight hot spot upwelling off the coast of Costa Rica. But I simply can’t see enough energy in this venting … Continue reading

Argo and the Ocean Temperature Maximum

Guest Post by Willis Eschenbach It has been known for some time that the “Pacific Warm Pool”, the area just northeast of Australia, has a maximum temperature. It never gets much warmer than around 30 – 31°C. This has been … Continue reading

Where in the World is Argo?

Guest Post by Willis Eschenbach The Argo floats are technical marvels. They float around below the surface of the ocean, about a kilometre down, for nine days. On the tenth day, they rise slowly to the surface, sampling the pressure, … Continue reading

More Evidence that Global Warming is a False Alarm

Roy Spencer writes on his website: NASA’s James Hansen is probably right about this point: the importance of ocean heat storage to a better understanding of how sensitive the climate system is to our greenhouse gas emissions. The more efficient … Continue reading
