Two new studies from BONUS COCOA have lately been published:
and co-authors investigated the erodibility potential of coastal sediments and identified
regulating key factors of sediment resuspension. The study took place at the South-Western
Finnish Archipelago coast, which offers a divers habitat of different sediment
types. Measurements were done with a core based erosion device (EROMES) at the
Tväminne Zoological Station. The full
study and all interesting outcomes can be found here:

properties, biota, and local habitat structure explain variation in the
erodibility of coastal sediments. Limnology and Oceanography, doi:10.1002/lno.10622.
Mari and the EROMES device; during field work usually to be found in TZS´s climate controlled basement.
and co-authors estimated the filter function of Baltic Sea coastal sediments for
the elements nitrogen (N) and phosphorus (P), i.e. they calculated how much N and
P is permanently removed from the coastal Baltic water column via benthic denitrification
and burial, respectively. For this, they compiled and analyzed published removal
rates of N and P from around the Baltic Sea coastline and could, for instance, identify
key environmental factors for the regulation of N and P in the coastal filter. For more on this and the main outcome (no spoiler here) please look at:
Carstensen J, Conley DJ, Slomp CP, Stadmark J, Voss M (2017) Efficiency of the
coastal filter: Nitrogen and phosphorus removal in the Baltic Sea. Limnology
How efficient is the coastal filter for N and P? Eero and colleagues dug through a lot of published literature.
Excellent Baltic Sea must-reads for the long autumn evenings!
