Guruvayoorappan_Diatom dataset from the core NP06-16/41 GC2 from the Kongsfjorden, Svalbard [dataset]

Description

Here, we present datasets of diatom relative abundance and a diatom-based sea surface temperature reconstruction from Kongsfjorden, Svalbard. The marine sediment core NP06-16/41 GC2 was recovered by the Norwegian R/V Lance using a gravity corer. The 454 cm long marine sediment core NP06-16/41 GC2 was recovered from the Kongsfjorden mouth (79 °1.15’N and 11 °19.27’E) during the cruise NP06-16 in August 2006, at 331m water depth. The sediment core section from 300 to 454 cm was used for diatom analysis. One extra sample of 1 cm thickness was taken between each 5 cm interval, increasing the number of samples upto 62, between the 300 to 454 cm section. Diatoms were analysed using standard procedures, including the identification and counting of a minimum of 300 diatom per sample, which allowed calculation of the percentage abundances of different species. These abundances were converted into estimates of sea surface temperature using the weight averaging partial least squares transfer function approach.
