来自挪威海和格陵兰海的36个岩心顶部的底栖有孔虫已根据测试形状、盘绕性质和壁孔的存在或不存在被放入形态类型类别。这些形态型具有独特的模式与水深，并与特定物种的微生境偏好。形态型数据被用来重建该地区的有孔虫微生境的水深分布。底栖动物形态型主要存在于浅水沉积物（<1 250米）中，而表栖动物形态型则存在于较深水深（> 1 500米）的沉积物样品中。本研究中记录的形态模式与挪威西南大陆边缘观察到的相似，表明这些模式存在于格陵兰海和挪威海的大部分地区。
Benthic foraminifera from 36 core tops from the Norwegian and Greenland seas have been placed into morphotype categories based on test shape, nature of coiling, and the presence or absence of wall pores. These morphotypes have distinctive patterns with water depth and are related to species-specific microhabitat preferences. The morphotype data are used to reconstruct the water depth distribution of foraminiferal microhabitats in the region. Infaunal morphotypes exist predominantly in shallow-water sediments (< 1250 m) while epifaunal morphotypes are found in sediment samples from deeper water depths (> 1500 m). The morphological patterns documented in this study are similar to those observed on the southwestern continental margin of Norway, demonstrating that these patterns exist over a large part of the Greenland and Norwegian seas.
