Sediment trap and deep sea coretop sediments as tracers of recent changes in planktonic foraminifera assemblages in the southeastern ultra-oligotrophic Levantine Basin

Sediment trap and core top sediments were used to study the seasonal and longer-term variability in the distribution and assemblage composition of planktonic foraminifera (PF) in the ultra-oligotrophic Eastern Mediterranean Levantine Basin (LB). A continuous time series of particulate flux sampled every 11–12 days were retrieved from a sediment trap deployed at 1300 m between May 2017 and May 2018. The core top sediments were collected close to...
