NEW NODC DATASET: THERMOSTERIC SEA LEVEL ANOMALIES
Posted by Bob Tisdale
Just a quick one-graph post.
The NOAA National Oceanographic Data Center (NODC) has added Thermosteric Sea Level Anomaly data to its GLOBAL OCEAN HEAT CONTENT webpage. The NODC describes the data as, “The time series of yearly and 3-month thermosteric sea level anomaly are presented for the 0-700 meters layer. There is one file of yearly and four files of 3-month thermosteric sea level anomaly for each of four major oceanic basins: the World Ocean, the Pacific Ocean, the Atlantic Ocean (which includes the entire Arctic Ocean), and the Indian Ocean. Each file contains the integral for the entire basin (OB), the northern hemisphere part of the basin (NHPB), and the southern hemisphere part of the basin (SHPB).”
The following graph compares the Global and North Atlantic+Arctic Ocean Thermosteric Sea Level anomalies. I suspect that much of the flattening in the global data since 2003 is caused by the significant drop in the North Atlantic+Arctic Ocean data.

(Yippee, a new dataset to play with.)
