06.11.2017 20:55New Dr. in COCOA! (Sources & Sinks: A Tale of Coastal Biogeochemistry - BONUS COCOA)

COCOA PhD student Ines Bartl (Leibniz Institute for Baltic Sea Research Warnemuende) successfully defended her doctoral thesis on

"Nitrogen transformation processes in coastal zones of the Baltic Sea - On the turnover, regulation and role of coastal nitrification"

....and hence is from now on Dr. Bartl!
Picture credit: Ines Bartl.

During her PhD, supervised by Maren Voss, Ines sailed both stormy and calm waters of the southern and northern Baltic Sea and spent hours, days and nights in cold rooms, spiking water samples from the benthic boundary layer with nitrogen tracer, followed by filtering, filtering and...filtering. 


All the hard work was totally worth it: big congratulations to your great achievement!!

21.09.2017 19:28New COCOA publications out! (Sources & Sinks: A Tale of Coastal Biogeochemistry - BONUS COCOA)

Two new studies from BONUS COCOA have lately been published:

Mari Joensuu 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:

Joensuu M, Pilditch AC, Harris R, Hietanen S, Pettersson H, Norkko A (2017) Sediment 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.

Eero Asmala 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:

Asmala E, 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 and Oceanography.doi:10.1002/lno.10644

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!
