Supplementary data:


The aim of R/V Alkor cruise AL438 was to investigate the assemblage composition,
population density and distribution of Recent benthic foraminifera in the Elbe
estuary and southern North Sea. We focused on an assessment of the present state of
the ecosystems and a comparison with data from former decades. Our work resumed
investigations of the Geologisch-Paläontologisches Institut of Kiel University and the
Federal Hydrographic Office from 1960s till the 1980s, as well as topical studies to the
west of Helgoland. We revisited the same stations and took sediment samples with
historical and modern grab samplers, box corer, Minicorer and a gravity corer. These
samples were accomplished with samples from new stations in order to describe the
relationships of foraminiferal faunas living in the Helgoland mud area with those
inhabiting the surrounding sands. The sampling was accompanied with hydrographical
measurements and water sampling to document relevant environmental parameters.
The foraminiferal sampling was carried out for the first time following of the
FOraminiferal BIoMOnitoring group (FOBIMO) recommendations as much as possible,
in order to test the practicability of the guidelines. In total, 109 deployments at 37
stations were successfully accomplished.
