| contents | Benthic foraminifera were studied in the core LV76-21 sediments sampled in 1 cm-thick slices. All the samples were dried, weighted, and wet sieved using a 63 μm sieve. The benthic foraminifera shells were picked and counted from the 63–250 μm sediment fraction. In total, 222 samples were analyzed at an average resolution of 2.5 cm (range 1–5 cm). Almost all the samples had enough microfossils for representative evaluation, except for intervals 365 cm, 398–408 cm, 435–440 cm, 444–465 cm, and 490–510 cm, where foraminifera were rare or absent. The total benthic foraminifera abundance (BFA) expressed as the number of shells per 1 g of dry sediment (shells x g^−1). |
