“…Our results are within the range of the results obtained from different studies performed in Baltic Sea in which the spectrum of the results is much wider (Kononen et al, 1993;Mazur and Pliński, 2003;Henriksen, 2005). In this study, the correlation between the nodularin concentration and the N. spumigena density was found to be high (R 2 = 0.88) and close to the findings of Mazur-Marzec et al (2013) in Baltic Sea (R 2 =0.895), while relatively lower than that of Henriksen (2005) (R 2 = 0.95). Nodularin is a potent hepatotoxin in humans and animals (Pearson et al, 2010).…”

“…N. spumigena blooms have been reported from brackish waters of Australia (Heresztyn and Nicholson, 1997;McGregor et al, 2012), America (Beutel et al, 2001), Africa (Harding et al, 1995), Baltic Sea (Kononen et al, 1993;Mazur and Pliński, 2003;Henriksen, 2005;Mazur-Marzec et al, 2006, 2013Suikkanen et al, 2007, Kankaanpää et al, 2009, and Caspian Sea (Nasrollahzadeh et al, 2011). The mass occurrence of N. spumigena in Lake Burdur was recorded in 2000 for the first time and second for the brackish waters of Turkey (Gülle et al, 2010), the species now the most dominant cyanobacteria species in Lake Burdur.…”

“…Holland et al (2013) reported that the Nodularia blooms occurred in waters with salinity between 9-20 and the water temperature above 20°C. Several study results (Mazur and Pliński, 2003;Mazur-Marzec et al, 2006) demonstrated that growth of the N. spumigena is strongly temperature-dependent and is optimal at 25-28°C. In our study, during the bloom, water temperature was 25-28°C and salinity was 19.83-20.05 g L -1 .…”

“…(Mazur-Marzec et al 2008). Also in Lake Białe, an exceptionally high concentration of MCs was measured (26,180.8±76.5 µg dm -3 ) during a monospecies bloom of D. lemmermannii (Mazur-Marzec et al 2010). The different values of MCs concentrations reported in studies from the same area can be explained by the dynamic character of cyanobacterial blooms.…”

In this work, the authors examined the presence of cyanobacteria and cyanotoxins in 21 samples collected from fresh water bodies located in 5 provinces in Poland: Lublin (2), Podlasie (1), Pomerania (6), Warmia-Masuria (1) and Wielkopolska (11). In addition, to determine the general pattern of geographical distribution, frequency of cyanobacteria occurrence, and cyanotoxins production, the published data from 238 fresh water bodies in Poland were reviewed. On the basis of these collected results, we concluded that Planktothrix, Aphanizomenon, Microcystis and Dolichospermum were dominant. The general pattern in geographical distribution of the identified cyanobacterial genera was typical of other eutrophic waters in Europe. The production of cyanotoxins was revealed in 18 (86%) of the 21 samples analyzed in the present work and in 74 (75%) of the 98 total water bodies for which the presence of toxins had been examined. Among the 24 detected microcystin variants, [Asp 3 ]MC-RR was most common. These results can be verified when more data from the less explored water bodies in the southern and eastern parts of Poland are available.

“…In summer, the Baltic Sea phytoplankton assemblage is dominated by filamentous cyanobacteria species such as A. flos-aquae, N. spumigena, and Dolichospermum sp., and picocyanobacteria species such as Synechococcus sp. [60,61]. The filamentous species, A. flos-aquae, N. spumigena, and Dolichospermum sp., are rich in phycocyanin, while the non-filamentous Synechococcus sp., which significantly contributes to total phytoplankton biomass, is rich in phycoerythrin.…”

A Novel Statistical Approach for Ocean Colour Estimation of Inherent Optical Properties and Cyanobacteria Abundance in Optically Complex Waters

Abstract:Eutrophication is an increasing problem in coastal waters of the Baltic Sea. Moreover, algal blooms, which occur every summer in the Gulf of Gdansk can deleteriously impact human health, the aquatic environment, and economically important fisheries, tourism, and recreation industries. Traditional laboratory-based techniques for water monitoring are expensive and time consuming, which usually results in limited numbers of observations and discontinuity in space and time. The use of hyperspectral radiometers for coastal water observation provides the potential for more detailed remote optical monitoring. A statistical approach to develop local models for the estimation of optically significant components from in situ measured hyperspectral remote sensing reflectance in case 2 waters is presented in this study. The models, which are based on empirical orthogonal function (EOF) analysis and stepwise multilinear regression, allow for the estimation of parameters strongly correlated with phytoplankton (pigment concentration, absorption coefficient) and coloured detrital matter abundance (absorption coefficient) directly from reflectance spectra measured in situ. Chlorophyll a concentration, which is commonly used as a proxy for phytoplankton biomass, was retrieved with low error (median percent difference, MPD = 17%, root mean square error RMSE = 0.14 in log 10 space) and showed a high correlation with chlorophyll a measured in situ (R = 0.84). Furthermore, phycocyanin and phycoerythrin, both characteristic pigments for cyanobacteria species, were also retrieved reliably from reflectance with MPD = 23%, RMSE = 0.23, R 2 = 0.77 and MPD = 24%, RMSE = 0.15, R 2 = 0.74, respectively. The EOF technique proved to be accurate in the derivation of the absorption spectra of phytoplankton and coloured detrital matter (CDM), with R 2 (λ) above 0.83 and RMSE around 0.10. The approach was also applied to satellite multispectral remote sensing reflectance data, thus allowing for improved temporal and spatial resolution compared with the in situ measurements. The EOF method tested on simulated Medium Resolution Imaging Spectrometer (MERIS) or Ocean and Land Colour Instrument (OLCI) data resulted in RMSE = 0.16 for chl-a and RMSE = 0.29 for phycocyanin. The presented methods, applied to both in situ and satellite data, provide a powerful tool for coastal monitoring and management.
