Fig. 6From: Relationship between the Northern Pacific Gyre Oscillation and tree-ring cellulose oxygen isotopes in northeastern Japan a +MA and b +MJ mean SST anomalies for six negative tree-ring cellulose events (A.D. 1938, 1947, 1954, 1956, 1966 and 1981). c +MA and d +MJ mean SST anomalies for six positive tree-ring cellulose events (A.D. 1933, 1940, 1942, 1963, 1975, and 1987). Datasets were from ERSST (Smith et al. 2008), and these anomalies were calculated from the difference between SST in these years and the SST average during A.D. 1927–2010Back to article page
