Heavy minerals in Arctic Ocean surface sediments

This data set includes heavy mineral data from 1509 surface sediment stations used to produce the four distribution maps shown in Figure 5-13 of Stein (2008). Heavy minerals are determined by counting particles of the heavy subfractions 32-63 µm and/or 63-125 µm (separated from the bulk sediment using sodiummetatungstate with a density of 2.83 g cm-3 or bromoform with a density of 2.89 g cm-3) under a microscope. Maps have been compiled using the Ocean Data View software (Schlitzer, 2001) and data from Naugler (1967), Naugler et al. (1974), Behrends (1999), Peregovich (1999), Levitan et al. (1996, 1999, 2005), and Andreeva (www.pangaea.de/search?q=Andreeva), Klenova (www. pangaea.de/search?q=Klenova), Kulikov (www.pangaea.de/search?q=Kulikov), and Pavlidis (www.pangaea.de/search?q=Pavlidis).

本数据集包含1509个表层沉积物站位的重矿物数据，用于绘制Stein（2008）中图5-13所示的4幅分布图。重矿物通过镜下计数32~63 μm和/或63~125 μm重组分颗粒获得，该重组分颗粒使用密度为2.83 g·cm⁻³的偏钨酸钠或密度为2.89 g·cm⁻³的溴仿从全沉积物中分离得到。分布图采用海洋数据查看器（Ocean Data View，Schlitzer, 2001）软件编制，所用数据来源包括Naugler（1967）、Naugler等（1974）、Behrends（1999）、Peregovich（1999）、Levitan等（1996、1999、2005），以及Andreeva（www.pangaea.de/search?q=Andreeva）、Klenova（www.pangaea.de/search?q=Klenova）、Kulikov（www.pangaea.de/search?q=Kulikov）与Pavlidis（www.pangaea.de/search?q=Pavlidis）的相关研究数据。
