Image dataset of common benthic foraminiferal taxa in the North Atlantic seafloor surface sediments (59.5°N transect) between the Labrador sea and Faeroe-Shetland sill

Abstract

The article presents a microphotograph dataset of 106 taxa of benthic foraminifera (BF) from surface sediments collected at 26 grab station during RV Akademik Ioffe 51st cruise (summer 2016). The selected stations are located along a 59.5°N transect in the North Atlantic. This is the key area of climate control, where the interaction of warm surface and cold deep water masses takes place, which affects the operation of the global oceanic thermohaline circulation. The analysis of the benthic foraminiferal assemblages allows us to describe the properties of bottom water mass, to draw conclusions about the environmental parameters at the bottom. This photo dataset will facilitate the identification of species of BF, and thus will accelerate the routine process of micropaleontological analysis and the subsequent reconstruction of environmental conditions.

Image dataset of benthic foraminifera taxa from Denmark Strait sediments on the northwestern Iceland slope (North Atlantic Ocean)

“…To identify benthic foraminifera species, we used publications of Jones [4] , Feyling-Hanssen et al. [5] , Holbourn et al [6] ., Saidova [7] , Tikhonova et al [8] . Benthic foraminifera tests were photographed on the Nikon microscope SMZ25 equipped with a Nikon camera DS-Fi3 and NIS-Elements D software.…”

“…Then, microphotograph tables were edited by the computer software Adobe Photoshop CC 2019. To identify benthic foraminiferal taxa, we used publications by Feyling-Hanssen et al 1971 , Holbourn et al 2013 , Jones 1994 , Tikhonova et al 2019 .…”
