Abstract
The Arctic Ocean is presently the least understood ocean in the world. The
perennial sea ice that covers most of the Arctic has hindered exploration and
interpretation of this last remaining portion of the Earth’s surface. The geologic history of this ocean is not fully understood and needs to be studied in greater detail. The stratigraphic record in the Arctic is a topic of much debate, specifically when discussing
ages and sedimentation rates. Various ways of age dating has shed new light on ages and
sedimentation rates of the established stratigraphy. Proxies such as microfossils and isotope evidence are giving us new insights to the paleoceanography of the Arctic Ocean basin. Core 92AR-P25 from the Northwind Ridge shows correlation with the
paleomagnetic time scale and agreement with the manganese color cycles proposed by
Jakobsson et al, (2000). The correlation of the core, shows that many cores throughout
the Central Arctic Ocean can be similarly correlated, allowing us to form a
paleoceanography history of the Arctic Ocean.
