30+ Years of Ocean SSTs – January 1978 to July 2008

The following are graphs of SST anomalies from January 1978 to July 2008 for the:
North Atlantic
South Atlantic
North Pacific
South Pacific
Indian Ocean
Arctic Ocean
Southern Ocean

I found the following to be highlights:

- The absence of an immediate major reaction in the North Atlantic to the 97/98 El Nino.

- The flatness of the South Atlantic curve.

- The decline in North Pacific SST since 2005, though the PDO is said to have just recently "shifted".

- The relative flatness of the South Pacific curve before the 97/98 El Nino and then the rise and fall afterwards.

- The saw-toothed step changes in Indian Ocean SST after the 82/83, 86/87/88, and 97/98 El Ninos.

- The 1990 peak in Arctic SSTs (not 2007 or 2008).

- The continuous decline in Southern Ocean SSTs since the mid 80s.

I haven’t yet discovered what day of the month the SST data on NOMADS are updated, but obviously, it’s by the 16th. I will attempt to revise them monthly.

The Smith and Reynolds SST Posts DOES NOT LIST ALL SST POSTS. I stopped using ERSST.v2 data for SST when NOAA deleted it from NOMADS early in 2009.

NOTE: I’ve discovered that some of the links to older posts provide blank pages. While it’s possible to access that post by scrolling through the history, that’s time consuming. There’s a quick fix for the problem, so if you run into an absent post, please advise me. Thanks.
