Opis:
W sezonie zimowym 2006/2007 przebieg zlodzenia Hornsundu był odmienny od przeciętnego. Od listopada do marca średnia miesięczna temperatura powietrza była o 3.6–6.3 deg wyższa od średniej klima-tycznej (1978–2006). Ujemna temperatura wody powierzchniowej przy brzegu Isbjornhamny występowała od 28 IX 2006 do 27 V 2007 r. Najniższe wartości temperatury wody mierzono w drugiej i trzeciej dekadzie października (–1.8°C). Latem i jesienią 2006 r. dochodziło do bardzo intensywnego obłamywania się lodu lodowcowego, który okresowo tworzył zwarte skupienia wzdłuż brzegu. Rozwój lodu morskiego w Isbjornhamnie cechuje się stadial-nością. Pierwszy okres tworzenia się lodu morskiego miał miejsce między 6 października a 3 listopada, drugi – od połowy stycznia. W tym samym czasie dryfujący lód allochtoniczny pojawił się również na przedpolu fiordu. Od trzeciej dekady lutego do drugiej dekady kwietnia prawie cała powierzchnia Hornsundu pokryta była lodem dryfu-jącym o zmiennej zwartości. Na osiowej partii fiordu lód morski zanikł po 25 kwietnia, a w Brepollen – w trzeciej dekadzie czerwca 2007 r. Maksymalna wysokość wału lodu nabrzegowego w Isbjornhamnie osiągnęła 2.5 m.
This article presents the development of sea ice cover in the waters of central and western part of the Hornsund Fjord, as well as in its foreshore during winter season 2006–2007. Due to long lasting (November-March) high air temperatures (Fig. 1) the sea ice cover development of Hornsund was different from the average one. Significant decrease in air temperature was observed only in April (mean monthly –8.7°C). In such thermal conditions the maximum thickness of sea ice which might have been formed in the outer, sheltered from high seas areas of the fjord, estimated with the help of Zubov formula, could reach 47cm in January, 58cm in February, 66cm in March, up to 77–80cm in the period from April to May 2007 (Tab.1). In summer and autumn 2006 only brash glacier ice and small icebergs broken off the glaciers endings on the sea in Hornsund drifted in the waters of the fjord. At this time brash glacier ice and growlers broken off the Hans Glacier periodically concentrated densely along the coast of Isbjorhamna. The first forms of new ice (slush and grease ice as well as shuga) were observed close to the west coast of Isbjornhamna from 6th October till 3rd November. The second period of sea ice formation started on 7th December. However, the ice disappeared quickly because of strong winds. Not sooner than in the middle of January when severe frost was noted, a permanent ice cover was formed (young ice). But also this ice was broken and diverged in most part of the fjord. Fast ice was only observed in the internal waters of Hornsund, in the Brepollen, Burgerbukta and Samarinvagen bays. From the third decade of February till the end of April the ice cover of Hornsund experienced large fluctuations. During that period the entire area of Hornsund was covered with sea ice a few times. This phenomenon was noted when the allochtonic ice drifting in the waters of the Sorkapp Current entered western and central part of the fjord and when the central and inner parts were covered with ice formed in situ. This sea ice cover was several times destroyed by very strong east winds causing that most of ice was moved outside the fjord. At the beginning of May very strong E and SE winds caused ice removal from the axial part of Hornsund. Later, apart from two short episodes (19-29 May and 22-23 June) when open strips of allochtonic ice entered west and central part of the fjord, only single floes of broken-off the fast ice from Brepollen, Burgerbukta and Samarinvagen drifted in the waters of Hornsund. The ice season 2006/2007 ended on 19th July when the last floes of very rotten ice were observed drifting from the inside of the fjord with the tidal stream to its foreshore.

Opis:
Subject of the study are changes of the water temperature occurring on the Polish Baltic coast during years 1951-2010 (in Kołobrzeg, due to deficiencies in the data, for the years 1957-2010). It is expressed in the form of a linear trend. The study was based on the monthly average temperature of the sea water in the following stations: Świnoujście, Międzyzdroje, Kołobrzeg, Władysławowo, Hel and Gdynia. For most of analyzed stations an increase in average annual temperature of the water were observed. The largest one was recorded in Gdynia. In Świnoujście there were no significant changes in water temperature except for the slight its drop in June. A significant increase in the water temperature occurred in Międzyzdroje in February, March, April and May; in Kołobrzeg in January and March; in Władysławowo in January, February, March, April and June and in Hel and Gdynia in February, March, April, May, July and August. The greatest changes were in April in Hel and Gdynia.
Przedmiot badań stanowią zmiany temperatury wody zachodzące na polskim wybrzeżu Bałtyku w latach 1951-2010 (w Kołobrzegu ze względu na braki w danych w latach 1957-2010), wyrażone w formie trendu liniowego. W pracy wykorzystano średnie miesięczne wartości temperatury wody w następujących miejscowościach: Świnoujście, Międzyzdroje, Kołobrzeg, Władysławowo, Hel oraz Gdynia. W większości analizowanych stacji (oprócz Świnoujścia i Kołobrzegu) nastąpił wzrost średniej rocznej temperatury wody. Największy odnotowano w Gdyni, gdzie temperatura wody wzrastała średnio o około 0,02°C rocznie. Istotny statystycznie wzrost temperatury wody nastąpił w Międzyzdrojach w lutym, marcu, kwietniu i maju, w Kołobrzegu w styczniu i marcu, we Władysławowie w styczniu, lutym, marcu, kwietniu i w czerwcu, a w Helu i Gdyni w lutym, marcu, kwietniu, maju, lipcu i sierpniu. Największe zmiany następowały w kwietniu (w Helu i Gdyni powyżej 0,03°C rocznie). W Świnoujściu nie wystąpiły istotne zmiany temperatury wody z wyjątkiem niewielkiego jej spadku w czerwcu.

Opis:
Five years (1998, 2000–2003) of summer records of temperature, nutrients and dissolved oxygen concentrations in the upper 400 m of the water column of the northern Gulf of Aqaba were employed to produce a simple statistical model of the relationship between temperature versus nitrate, phosphate, silicate andd issolved oxygen concentrations. Temperature profiles in the upper 400 m during summer revealeda clear thermocline in the upper 200 m. This was reflected in nutrient ando xygen concentrations as nitrate, phosphate, and silicate increasedfr om the surface to deep water while dissolved oxygen decreased. The best fit relationship between temperature versus nitrate andphosphate was inverse linear and the best fit correlation between temperature versus silicate andd issolvedo xygen was fractional. The observedn utrient concentrations were shaped by a combination of the hydrodynamics and biological factors. Deep winter mixing and high nutrient concentrations dominate during winter. Shortly after the water stratifies in spring, the nutrients are drawn down by phytoplankton during the spring bloom and remain low throughout the rest of the year. The regression equations presented here will be useful in estimating nutrient concentrations from temperature records as long as the annual natural cycle is the main driver of nutrient concentrations and external inputs are insignificant. Deviations from these relationships in the future could provide insight into modifications in the nutrient concentrations probably resulting from new nutrient sources, such as anthropogenic inputs.

The first part of the Baltic Sea ecohydrodynamic model, based on the Princeton Ocean Model (POM), was validated by long-term observations of sea level, salinity and water temperature fluctuations. The modelled sea surface temperature (SST) fields were also compared to satellite images – satisfactory correlation coefficients were obtained. The model bias and efficiency coefficients of the modelled variables in relation to the observed values were determined. The quality of model simulations in relation to measured values was estimated with respect to spatial and seasonal variability in shallow and deep coastal waters as well as in the open sea. The results indicated the high quality of simulations by the hydrodynamic model.

Opis:
A medium-sized inflow (about 200 km3 according to IOW data, - personal communication) of saline water into the southern Baltic Sea occurred during January 2003. Unlike any previously observed inflow, this one brought very cold water, of temperatures around 1-2oC and less. Since the temperature of the deep water in the southern Baltic before the inflow was exceptionally high (11-12oC), the inflowing waters produced dramatic changes and a steep temperature gradient. The movement of the inflowing waters through the deep basins and channels of the Baltic Sea from the Arkona Basin to the Gdańsk Deep during next 4-8 months is described. Frequent mesoscale structures and intensive mixing followed the eastward transport of the inflow water, particularly in the Bornholm Deep and Słupsk Furrow. The present paper is based on data collected during 6 cruises r/v "Oceania" between December 2002 and August 2003. The last cruise in August took place in order to assess the long-term consequences of the inflow.

Opis:
The cold intermediate water (CIW, T<8◦C) entering the Strait of Istanbul and its variation along the strait have been studied by using monthly conductivitytemperature- depth (CTD) data sets collected during the period from 1996 to 2000. In the northern exit of the strait, CIW is located between the seasonal thermocline and Mediterranean water originating from the lower layer of the Sea of Marmara. The thickness of CIW decreases from April to October. In the Strait of Istanbul, CIW is observed as a layer of temperature <14◦C. The thickness of this modified cold intermediate water flowing southwards with the upper layer decreases, while its temperature increases along the strait due to mixing with adjacent water. In the southern exit of the strait, the modified cold intermediate water is observed during the period from May to October. If CIW exists in the Black Sea exit region of the strait, modified cold water is found in the Marmara exit region during the same period. The distribution of CIW in the Strait of Istanbul contributes to our understanding of the dynamics of the strait, especially in the summer months.

Opis:
From October 2002 until March 2003 surprisingly warm, oxygenated waters were frequently encountered in the Baltic Sea in the area between the Bornholm and Fårö Deeps from the halocline down to the bottom. Owing to their ventilation effect in the stagnating deep waters, their occasional observations have partly been incorrectly attributed to the inflow events of October 2002 or January 2003. The emergence of some of these waters can be traced back to the exceptional summer weather conditions in August and September 2002 in central Europe. The warm waters played a remarkable renewal pacemaker role for the subsequent important winter inflow of January 2003. The evolution of this summer inflow is described and possible causes are discussed.

Opis:
The conductivity-salinity conversion algorithm used for oceanographic measurements of Practical Salinity on the PSS-78 scale is designed for IAPSO Standard Seawater. The application of this formula to a given sample of non-standard seawater does not necessarily result in a constant salinity value when the sample’s conductivity is measured at different temperatures.We have experimentally studied the magnitude of this non-conservative effect of Practical Salinity using a sample of Baltic seawater possessing a density anomaly of about 50 g m−3. The apparent change of salinity observed is at the limit of experimental uncertainty and is not significantly different from the drift of Standard Seawater, which was measured for comparison.

Opis:
The Indian marine environment supports employment for over 200 million people, including revenue of nearly $7 billion per annum. However, ecological goods and services of the shallow coast and the marine environment of the Indian peninsula are being affected by recurrent blooms of microalgae. One hundred and six published literature, starting from the first report in 1908 to 2017, were reviewed to investigate the historical occurrences of marine microalgal blooms (MMBs) around the Indian peninsula. 154 MMBs comprising 24 genera and 7 classes were reported during the study period. Noctiluca (dinophyceae) and Trichodesmium (cyanophyceae) bloom contributed 34.4% and 31.8% of total blooms. PCA revealed that high sea surface temperature (SST) and salinity were significant driving forces for Trichodesmium blooms formation, while high nutrients (NO3-N, PO4-P, and SiO4-Si) and low salinity triggered prymnesiophyceae, raphidophyceae, bacillariophyceae and most of the dinophyceae blooms. Noctiluca blooms were linked with both eutrophication and the abundance of prey organisms. HABs were generally dinophyceae dominated and were associated with mass mortality of aquatic fauna, human intoxication, paralytic, and ciguatera shellfish poisoning and even death. Increasing SST and anthropogenic influences around the Indian peninsula could increase the occurrences of MMBs (including HABs) and the number of causative taxa. Proper safety measures such as routine monitoring of phycotoxin levels in the environment and local seafood are required to be put in place in other to protect the health of the public.

Opis:
Svalbard archipelago, a high latitude area in a region undergoing rapid climate change, is relatively easily accessible for field research. This makes the fjords of Spitsbergen, its largest island, some of the best studied Arctic coastal areas. This paper aims at answering the question of how climatically diverse the fjords are, and how representative they are for the expected future Arctic diminishing range of seasonal sea-ice. This study uses a meteorological reanalysis, sea surface temperature climatology, and the results of a recent one-year meteorological campaign in Spitsbergen to determine the seasonal differences between different Spitsbergen fjords, as well as the sea water temperature and ice ranges around Svalbard in recent years. The results show that Spitsbergen fjords have diverse seasonal patterns of air temperature due to differences in the SST of the adjacent ocean, and different cloudiness. The sea water temperatures and ice concentrations around Svalbard in recent years are similar to what is expected most of the Arctic coastal areas in the second half of this century. This makes Spitsbergen a unique field study model of the conditions expected in future warmer High Arctic.

Opis:
Relationships between the zooplankton community andv arious environmental factors (salinity, temperature, sampling depth and bottom depth) were established in the European Arctic Marginal Ice Zone (MIZ) using multivariate statistics. Three main zooplankton communities were identified: an Atlantic Shallow Community (AtSC), an Arctic Shallow Community (ArSC) anda Deep Water Community (DWC). All species belonging to AtSC andArSC were pooledandtheir relative abundances in the total zooplankton calculated with respect to a particular layer (surface, midan dd eep strata), regions (the Barents Sea, Fram Strait andt he waters off northern Svalbard), years (1999 or 2003) and seasons (spring or autumn). Mapping of the proportions of Arctic andA tlantic species ledto the conclusion that zooplankton from the MIZs do not exactly follow complementary water masses, although the general pattern of AtSC and ArSC dominance accords with the physical oceanography of the study area (AtW and ArW respectively). The mid layer proved to be a better predictor of mesozooplankton distribution than the unstable conditions near the surface.

Opis:
Changes in the basic physical properties of selected areas of the Baltic Proper were analysed on the basis of the results of a 12-year series of high-resolution measurements collected during cruises of r/v ‘Oceania’. The high-resolution CTD sections covered three main basins: the Bornholm Basin, Słupsk Furrow and Gdańsk Basin. Positive temperature trends of 0.11 and 0.16◦C year−1 were observed in the surface and deep layers respectively. The salinity trend was also positive. The rise in the air temperature has probably caused the increase in surface water temperature, while advection has been of greater significance in the deep layer. The increase in salinity coincides with the more frequent occurrence of small and medium-size inflows through the Danish Straits, even though large inflows are evidently less frequent than used to be the case. The seasonal variability of temperature in the water column was analysed. The phase shift in the seasonal evolution with depth is described. The maximum temperature shift in the waters investigated varies from 32 to 38 days.

Opis:
Since 1987 annual summer cruises to the Nordic Seas and Fram Strait have been conducted by the IO PAN research vessel Oceania under the long-term monitoring program AREX. Here we present a short description of measurements and preliminary results obtained during the open ocean part of the AREX 2016 cruise. Spatial distributions of Atlantic water temperature and salinity in 2016 are similar to their long-term mean fields except for warmer recirculation of Atlantic water in the northern Fram Strait. The longest observation record from the section N along 768300N reveals a steady increase of Atlantic water salinity, while temperature trend depends strongly on parametrization used to define the Atlantic water layer. However spatially averaged temperature at different depths indicate an increase of Atlantic water temperature in the whole layer from the surface down to 1000 m.

Opis:
Coastal upwelling often reveals itself during the thermal stratification season as an abrupt sea surface temperature (SST) drop. Its intensity depends not only on the magnitude of an upwelling-favourable wind impulse but also on the temperature stratification of the water column during the initial stage of the event. When a ‘chain’ of upwelling events is taking place, one event may play a part in forming the initial stratification for the next one; consequently, SST may drop significantly even with a reduced wind impulse. Two upwelling events were simulated on the Polish coast in August 1996 using a three-dimensional, baroclinic prognostic model. The model results proved to be in good agreement with in situ observations and satellite data. Comparison of the simulated upwelling events show that the first one required a wind impulse of 28 000 kg m−1 s−1 to reach its mature, full form, whereas an impulse of only 7500 kg m−1 s−1 was sufficient to bring about a significant drop in SST at the end of the second event. In practical applications like operational modelling, the initial stratification conditions prior to an upwelling event should be described with care in order to be able to simulate the coming event with very good accuracy.

Opis:
A project was developed concerning the operational system of surveillance and the recording of episodic events in the Baltic Sea. In situ information was to be combined with multi-sensory satellite imagery to determine the extent of algal blooms, to track their evolution and that of rapid environmental events like hydrological fronts. The main element of the system was an autonomous Ferry Box module on a ferry operating between Gdynia and Karlskrona, automatically measuring temperature, salinity and chlorophyll a fluorescence. At pre-selected locations, discrete water samples were collected, which were subsequently analysed for their phytoplankton content, and algal hepato- and neurotoxins; they were also used in toxicity tests with Artemia franciscana.
