“…The pattern of currents is extremely complex and main tidal streams are often split in secondary flows by the various island; moreover, in some areas, peculiar mixing situations are generated also (Tzetlin et al, 1997;Berger and Naumov, 2000;Savvichev et al, 2003). The unique hydrodynamics of the bay is also affected by seasonal intense runoffs of freshwater, due to various rivers, streams and strong precipitations (Howland et al, 1999;Dolotov et al, 2005), which contribute to enrich the sea water with nutrients and microorganisms from the surrounding soils, forests and peatlands. On the other hand, these inputs, carrying particulate and humic substances, cause intense water darkening with consequent strong reduction of the photic zone, which is…”

“…Kandalaksha Bay (KB), the northernmost White Sea region, is an estuarine system showing large sea level differences during tide cycles; this produces intense water mixing affecting microbial and nutrient distribution (Melnikov et al 2003;Savvichev et al 2003;Pesciaroli et al 2015). Moreover, due to various rivers and strong precipitations, seasonal intense freshwater inputs contribute to frequent changes of nutrient availability and composition (Howland et al 1999;Dolotov et al 2005).…”

Relationship between phylogenetic and nutritional diversity in Arctic (Kandalaksha Bay) seawater planktonic bacteria

Due to huge yearly variations of environmental stressing conditions, Kandalaksha Bay (Arctic Circle, White Sea, Russia) could represent a model to study microbial adaptation in extreme environments. This peculiar estuarine system has been scarcely investigated for its microbial diversity. In this work, to gather information on their nutritional competencies, seawater planktonic bacteria were studied for their ability to use different carbon sources by the Biolog phenotype microarray assays. Nestedness, a useful statistical tool used in ecology, was employed to underline nutritional differences among microbial groups. In particular, nestedness was used to understand the complex relationship that is established when many nutrients are available for various microorganisms, and to highlight presence of specialists and generalists. Among the studied bacteria, which showed very diverse nutritional abilities, 47% belonged to Pseudomonas, 21% to Serratia and 32% to other Genera. Within Pseudomonas, both highly generalist and highly specialist strains were discovered. However, most of them used organic and/or amino acids as principal carbon sources. In contrast, Serratia strains typically preferred sugars and appeared to be more generalist. On the whole, important differences in specialization levels and nutritional competencies were recorded in strains belonging to the same species. Correlations between phylogenetic and nutritional data were validated by Procrustes analysis.

Abstract. The biogeochemistry of the river-sea interface was studied in the Kem' River (the largest river flowing to the White Sea from Karelian coast) estuary and adjacent area of the White Sea onboard the RV "Ekolog" in summer 2001, 2002 and 2003. The study area can be divided into 3 zones: I -the estuary itself, with water depth from 1 to 5 m and low salinity in the surface layer (salinity is lower than 0.2 psu in the Kem' River and varies from 15 to 20 psu in outer part of this zone); II -the intermediate zone with depths from 5 to 10 m and salinity at the surface from 16 to 22 psu; IIIthe marine zone with depths from 10 to 29 m and salinity 21-24.5 psu. Highest concentrations of the suspended particulate matter (SPM) were registered in the Kem' mouth (5-7 mg/l). They sharply decreased to values <1 mg/l towards the sea. At beginning of July 2001, particulate organic carbon (POC) concentration in the river mouth was 404 µg/l and POC content in total SPM was 5.64%. In the marine part of the studied area the POC concentration varied from 132 to 274 µg/l and the POC contents in suspended matter increased to 19-52.6%. These studies show, that the majority of riverborne suspended matter in the Kem' estuary deposits near the river mouth within the 20 psu isohaline, where sedimentation of the suspended matter takes place. The role of freshwater phytoplankton species decreases and the role of marine species increases from the river to sea and the percentage of green algae decreases and the role of diatoms increases. The organic carbon (C org ) to nitrogen (N) ratio (C org /N) in both suspended matter and bottom sediments decreases from the river to the marine part of the mixing zone (from 8.5 to 6.1 in the suspended matter and from 14.6 to 7.5 in the bottom sediments), demonstrating that content of terrestrial-derived organic matter decreases and content of marine organic matter Correspondence to: V. P. Shevchenko (vshevch@geo.sio.rssi.ru) increases from the river mouth to the sea. The Kem' estuary exhibits a similar character of biogeochemial processes as in the large Arctic estuaries, but the scale of these processes (amount of river input of SPM, POC, area of estuaries) is different.
