The role of fish and fisheries in Baltic Sea nutrient dynamics
fish and fisheries Baltic Sea nutrient dynamics
2014/5/27
Many studies show that fish and fisheries management can be important to freshwater nutrient dynamics, but similar reports from marine environments are scarce. In the Baltic Sea, we estimate the remov...
Maximum rates of N2 fixation and primary production are out of phase in a developing cyanobacterial bloom in the Baltic Sea
N2 fixation primary production in a developing cyanobacterial bloom Baltic Sea
2014/5/26
Although N2-fixing cyanobacteria contribute significantly to oceanic sequestration of atmospheric CO2, little is known about how N2 fixation and carbon fixation (primary production) interact in natura...
Do sediments from coastal sites accurately reflect time trends in water column phytoplankton? A test from Himmerfjärden Bay (Baltic Sea proper)
sites accurately reflect time trends water column phytoplankton Himmerfjä rden Bay
2014/5/26
Long-term (1977-2000) ecological biomass data for total phytoplankton, diatoms, and cyanobacteria, based on plankton samples from Himmerfjärden Bay (Baltic proper), were compared to the historica...
Baltic Sea nitrogen fixation estimated from the summer increase in upper mixed layer total nitrogen
Baltic Sea nitrogen fixation the summer increase upper mixed layer total nitrogen
2014/6/9
We estimated nitrogen fixation from the increase in total nitrogen (N2 gas excluded) in the upper 20 m during the summer biomass increase of heterocystous filamentous cyanobacteria at the off-shore La...
Mineralogical and Rb-Sr Isotope Studies of Low-Temperature Diagenesis of Lower Cambrian Clays of the Baltic Paleobasin of North Estonia
Baltic Paleosedimentary Basin Cambrian Low-Temperature Diagenesis Illitization
2011/12/2
Abstract: X-ray diffraction (XRD), Rb-Sr isotope analysis, transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), and Fourier transform infrared (FTIR) methods were used t...
Fluctuation of dominant mesozooplankton species in the Black Sea, North Sea and the Baltic Sea: Is a general trend recognisable?
Black Sea Baltic Sea North Sea climate mesozooplankton Aurelia Mnemiopsis Pleurobrachia Engraulis
2010/4/1
The distribution and fluctation of dominant pelagic species>300µ(Copepoda, Chaetognatha, Scyhozoa, Ctenophora and ichthyoplankton) of the southern Black Sea were compared with that of dominant s...
