Table 2.

The difference of the years 1941 (the height of the El Niño) and 1943 (the height of the La Niña) at each ice core site

Core	ITASE 00–1	ITASE 00–5	ITASE 01–3	ITASE 01–5	ITASE 01–2	Siple Station	Siple Dome	Dyer Plateau
1941–1943, SD	3.49	1.88	4.55	5.04	−2.96	3.96	3.09	2.67
1941–1943, ‰	3.20 (δ18O)	16.89 (δ D)	30.87 (δ D)	4.83 (δ18O)	−3.25 (δ18O)	2.58 (δ18O)	31.4 (δD)	2.24 (δ18O)

Values are in units of standard deviations from the 1961–1990 climatology and absolute per mil (‰) values, except at sites with end years before 1990; at these sites the climatology is calculated from 1961 to the end year.
