    Shifts in the proportion of dinoflagellates over the period of ten years (1995 to 2004).

    No full text
    <p>The predictions were made by geographically weighted linear regression and interpolated with ordinary kriging. Positive and negative values represent the areas of increasing and decreasing dinoflagellate proportion, respectively. Thick contour lines denote boundary between areas of increasing and decreasing trend.</p

    Long-term trends of diatoms and dinoflagellates in the Baltic Sea.

    <p>Lines depict the long-term trends of dinoflagellate and diatom biomass (column a), dinoflagellate proportion (column b) and seasonal pattern of dinoflagellate proportion (column c) in six major basins of the Baltic Sea; GoB – Gulf of Bothnia; GoF – Gulf of Finland and Archipelago Sea; NW – northwestern Baltic Proper; GoR – Gulf of Riga; SB – Southern Baltic Sea; Ka – Kattegat, the Belt Sea and the Sound. Symbols represent basin wide weekly averages; trend lines are predicted by GAM smoothers. Eastern Gotland Basin is not shown due to poor data coverage.</p

    <p>Gray symbols mark the sampled stations with the symbol area proportional to the number of samples. Lines and polygons indicate the regions pooled together for long-term analyses. The numbers represent the total amount of spring bloom samples, and the number of basin-wide weakly means used for long-term analysis.</p

    Effect of NAO on dinoflagellate proportions in six major basins.

    No full text
    <p>Basin-specific slope parameters (dinoflagellate proportion vs NAO index) from the mixed effects model with estimated standard errors and p-values. The parameter values quantify the change of the arcsin-square root transformed dinoflagellate proportion (range 0 to 1.5) per unit change of the NAO index.</p

    This file contains allelic information on 354 individuals (8 loci) of Skeletonema marinoi isolated from the Baltic Sea and NE North Sea

    growth rates

    No full text
    This file contains data on growth rates (intrinsic rate of increase, µ) of Skeletonema marinoi strains isolated from the Baltic Sea and the Swedish west coast. The average values are based on measured growth rates of 10 monoclonal strains grown in f/4+Si for 5-7 days in +10 C in a light intensity of 40 µmol s-1 m-2. Strains were acclimatized to respective salinity during one week prior to the growth experiment

    Spatial variability of the spring bloom peak biomass (wet weight, mg L<sup>−1</sup>) in the Baltic Sea.

    No full text
    <p>High biomass is characteristic to the eutrophied basins (Gulf of Finland, Gulf of Riga), with a biomass >6 mg L<sup>−1</sup>. For most of the Baltic Sea, peak biomass of the spring bloom samples falls between 1.5–3 mg L<sup>−1</sup>.</p
