Annotated record of the detailed examination of Mn deposits from DSDP Leg 94 (Holes 608, 609, 610A, 610B, 611)

Leg 94 represents the last of four transects of sites set up by the Ocean Paleoenvironment Panel to examine climatic and oceanographic changes in the Pacific and Atlantic oceans. During this leg, a transect of six holes aligned roughly in a south-southwest/north-northeast direction were drilled in the North Atlantic from 37° to 53°N. The principal objective of this transect was to document the magnitude and spectral character of the surface-ocean response to high-latitude climatic change in the northern hemisphere during the Neogene.

第94航次是海洋古环境专家组（Ocean Paleoenvironment Panel）为研究太平洋与大西洋的气候及海洋学变化所设立的四组测线站位中的最后一组。本航次期间，科研团队在北纬37°至53°的北大西洋海域，沿大致南南西/北北东方向布设并钻探了由六个钻井孔位组成的测线。该测线的核心目标是阐明新近纪（Neogene）时期北半球高纬度气候变化所引发的表层海洋响应的强度与频谱特征。
