Although evident in the paleotemperature record, there is no glacial‐interglacial difference in paleosalinity, suggesting that tropical hydrologic changes do not respond passively to high‐latitude ice sheets and oceans. Millennial variations in paleosalinity with amplitudes as high as ∼4 practical salinity units occur with a dominant period of ∼3–5 ky during the glacial/deglacial interval and ∼1.0–1.5 ky during the Holocene. The amplitude of the EPWP paleosalinity changes greatly exceeds that of published Caribbean and western tropical Pacific paleosalinity records. EPWP paleosalinity changes correspond to millennial‐scale climate changes in the surface and deep Atlantic and the high northern latitudes, with generally higher (lower) paleosalinity during cold (warm) events. In addition to Intertropical Convergence Zone (ITCZ) dynamics, which play an important role in tropical hydrologic variability, changes in Atlantic‐Pacific moisture transport, which is closely linked to ITCZ dynamics, may also contribute to hydrologic variations in the EPWP. Calculations of interbasin salinity average and interbasin salinity contrast between the EPWP and the Caribbean help differentiate long‐term changes in mean ITCZ position and Atlantic‐Pacific moisture transport, respectively.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380848661783839369","@type":"Researcher","foaf:name":[{"@value":"H.
