Abstract Stawy Dojlidzkie (The Dojlidy Ponds) are located in the north-eastern part of Poland, near the capital of the Podlasie province, in Białystok. The Dojlidy Ponds (DP) are a complex of more than 20 reservoirs arranged adjacent to one another in an area of about 140 hectares. The largest recreation reservoir (Plażowy) is located within the city limits. Its total area is 34 hectares, it has a capacity of 597 040 m3 and a maximum depth of approximately 2.5 m. DP are supplied by a tributary of the Dojlidy Górne and the River Biała, the principal river of Bialystok. Water tests of a limnic and lenitic character in the upper part of River Biała catchment in Bialystok were conducted from March to October 2014. Referring the obtained results to the actual norms, it can be concluded that most of the parameters analyzed in DP can be assigned to the first class of surface waters. Exceptions were the iron ions, orthophosphates (SRP), total phosphorus (TP), Kjeldahl nitrogen, and also water color and DOC. According to the evaluation of trophic status, the water of DP is eutrophic. The average value of TSI was 55 in the water of the tested objects. The obtained results show that the ecological status of water in the largest pond within the DP complex, in accordance with, the Ecological State Macrophyte Index (ESMI) represent to the good state.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.

Abstract The presented research focused on macrophytes, which constitute a primary element in the assessment of the ecological status of surface waters following the guidelines of the Water Framework Directive. In Poland, such assessments are conducted using the Macrophyte Index for Rivers (MIR). The objective of this study was to characterize macrophyte species in rivers in terms of their information value in the assessment of the ecological status of rivers. The macrophyte survey was carried out at 100 river sites in the lowland area of Poland. Botanical data were used to verify the completeness of samples (the number of taxa). In the presented research, the information provided by each species was controlled. Entropy was used as the main part of information analysis. This analysis showed that the adoption of a standard approach in the studies of river macrophytes is likely to provide sample underestimation (with missing species). This may potentially lead to incorrect determination of MIR and thus result in a wrong environmental decision. On this basis, a sample completeness criterion was developed. Using this criterion, the average value of information for macrophyte species in medium-sized lowland rivers is suffcient to be considered representative.

Bulqiza District is the largest chromium source, ranked fourth in the world for chrome reserves. It lays in the north-eastern part of Albania, 330-1800 m a.s.l, with 728 km² area, between 41o30’43.1N and 20o14’56.21E. There are 136 entities with chromium extraction activity and around the city of Bulqiza (2.6 km² and 13000 inhabitants), there are 33 entities. The aim of the study was the identification of the environmental state and environmental impact assessment of chromium extraction (chromite mining) and giving recommendations to minimize the negative effects of this activity. Field observations, questionnaires, chemical analysis of soil and water, meetings and interviews with central and local institutions as well as with residents were used for the realization of the study. The obtained results showed that chromium extraction causes numerous irreversible degradation of the environment in the Bulqiza area, such as the destruction of surface land layers and erosion, destruction of flora and fauna, soil and water pollution, health problems, unsustainable use and reduction of chromium reserves, etc. The inert waste that emerges after the chromium partition is discharged to the earth surface without any regularity, covering the surface of the soil and flora, leading to irreversible degradation of the environment. Most of the mining entities do not respect the contracts and environmental permit issued by the Ministry of Energy and Industry (MEI).

<p>In the North-Eastern part of Ukraine the forest communities occupy considerable area and have great ecological and economic value. In natural forests herbs and subshrubs maintain the canopy cover through the recovery mechanism when the undergrowth of woody plants by height constitutes a part of the herbaceous and subshrub layer. Cenoflora within the lower layers of mixed coniferous-broad leaved forests of the southern part of the Eurasian forest zone is a fairly complete structural unit, especially in the central parts of the moisture and soil fertility gradients. Syntaxonomic adaptability of the lower layer plants of the forest communities in the North-East of Ukraine is established, and their ecological and biological diversity is determined as a result of the researches conducted. A group of species of forest herbs and subshrubs by the ecological status takes an intermediate position because of their habitat versatility. The species of this group are characterized by the vegetative propagation along with the effective seed reproduction. The habitat versatility and combination of the two types of reproduction are the main reasons for a wide representation of the species of this group in different syntaxons. A high floristic biodiversity of the forest communities of the North-Eastern part of Ukraine and their flora heterogeneity are determined based on the comparative floristic analysis. The floristic difference between the two major classes of vegetation in this region is shown, and it is found that Querco-Fagetea class is characterized by a high nutrient status and good warming-up under slightly reduced soil moisture, whereas the main feature of Vaccinio-Piceetea class is low soil fertility.</p>

Geology of Greenland Survey Bulletin, 186, 50-59. https://doi.org/10.34194/ggub.v186.5215 _______________ The southern tip of Greenland is underlain by the Palaeoproterozoic Ketilidian orogen (e.g. Chadwick & Garde 1996; Garde et al. 1998a). Field investigations in the summer of 1999 were focused on the structure of migmatites (metatexites) and garnetiferous granites (diatexites) of the Pelite Zone in the coastal region of South-East Greenland between Lindenow Fjord and Kap Farvel (Figs 1, 2). Here, we first address the tectonic evolution in the Pelite Zone in that region and its correlation with that in the Psammite Zone further north. Then, the structure and intrusive relationships of the rapakivi suite in the Pelite Zone are discussed, including particular reference to the interpretation of the controversial outcrop on Qernertoq (Figs 2, 8). Studies of the structure of the north-eastern part of the Julianehåb batholith around Qulleq were continued briefly from 1998 but are not addressed here (Fig. 1; Garde et al. 1999). The field study was keyed to an interpretation of the Ketilidian orogen as a whole, including controls of rates of thermal and tectonic processes in convergent settings. Earlier Survey field work (project SUPRASYD, 1992–1996) had as its principal target an evaluation of the economic potential of the orogen (Nielsen et al. 1993). Ensuing plate-tectonic studies were mainly funded in 1997–1998 by Danish research foundations and in 1999 by the Natural Environment Research Council, UK. The five-week programme in 1999 was seriously disrupted by bad weather, common in this part of Greenland, and our objectives were only just achieved. Telestation Prins Christian Sund was the base for our operations (Fig. 2), which were flown with a small helicopter (Hughes MD-500).

Geology of Greenland Survey Bulletin, 183, 23-33. https://doi.org/10.34194/ggub.v183.5201 _______________ During a five week period in August–September 1998 the poorly known north-eastern part of the Palaeoproterozoic (c. 1800 Ma) Ketilidian orogen between Kangerluluk and Mogens Heinesen Fjord in South-East Greenland (Fig. 1) was investigated in continuation of recent geological research in other parts of the orogen. The north-eastern part of the orogen is remote from inhabited areas. It is mountainous and comprises a wide nunatak zone which can only be reached easily by helicopter. Furthermore, access to coastal areas by boat is difficult because many parts of the coast are prone to be ice-bound even during the summer months, due to wind- and current-driven movements of the sea ice.
