In the Angola Basin (Southern Hemisphere) the climatic signal shows a transition to more humid (\"interglacial\") conditions in equatorial Africa, and in the Canary Basin (Northern Hemisphere) to more \"glacial\" oceanic conditions. This trend is confirmed by comparison with all well-documented marine and continental records from various latitudes available; in the Northern Hemisphere, in the Atlantic north of 20°N, climate merged into more \"glacial\" conditions and in equatorial regions and in the Southern Hemisphere to more \"interglacial\" conditions. The data point to a more northern position of early Brunhes oceanic fronts and to an intensified atmosphere and ocean surface circulation in the Southern Hemisphere during that time, probably accompanied by a more zonal circulation in the Northern Hemisphere. The mid-Brunhes climatic change may have been forced by the orbital eccentricity cycle of 4.13 × 10\n            <jats:sup>5</jats:sup>\n            years.\n          </jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380567186807638274","@type":"Researcher","foaf:name":[{"@value":"J.
