Opis:
The report brings a comprehensive summary of archaeological fieldwork and survey carried out in Berenike on the Red Sea coast of Egypt and in the Eastern Desert hinterland over the course of two seasons in 2014 and 2015. The completed magnetic map of the site is discussed in some detail, assessing the potential for future excavations. The report covers the most important discoveries of the two seasons, which include fragments of Middle Kingdom Pharaonic stelae, possibly pushing back the foundation of the harbor, archaeological evidence of a rock-cut watercollection system forming part of the Hellenistic-age fortifications and two inscribed stone bases, one of which records a secretary of an aromatics warehouse at Berenike, discovered undisturbed in the courtyard of the Great Temple of Berenike (also called the Serapis Temple). A previously unknown religious(?) complex was discovered on the western outskirts of the site thanks to work with Corona satellite imagery. In turn, analysis of the magnetic mapping of the city revealed an administrative(?) complex in the northern part of the town; the later, 5th and 6th century layers were examined inside a chamber with niche forming part of this complex. Work also continued in the early Roman harbor, uncovering among others a complete timber ship frame, and a collection of garnets in subsidiary buildings in the late Roman temenos located in the entrance to the southwestern bay.

Al-Najaf Sea
Opis:
The Al-Najaf state is witnessing an increased economic development and attracting more investments that require the development of new areas and exploring new water resources. This study evaluates the quality of 12 surface water samples and groundwater from 12 wells for irrigation according to the salinity and sodicity hazards based on electrical conductivity (EC) and sodium adsorption ratio (SAR). In addition, the concentrations of radionuclides, which include Thorium (232Th), Uranium (238U), Potassium (40K) and Cesium (137Cs) were tested in four soil samples in the study area. It was found that the average values of pH, total hardness, Na, Ca, Mg, K, Cl, SO4, NO3 for groundwater and surface water were 8 and 6, 2287 and 4006 mg/L, 1140 and 1232 mg/L, 378 and 637 mg/L, 327 and 587 mg/L, 2 and 2 mg/L, 989 and 2007 mg/L, 1149 and 1325 mg/L, as well as 2 and 2 mg/L, respectively. From salinity and sodicity hazards analysis, the groundwater had EC of 5242 µS/cm and SAR of 61, whereas surface water had EC of 6253 µS/cm and SAR of 50. Furthermore, the concentrations of radionuclides, i.e. 232Th, 238U, 40K and 137Cs in the soil samples were found to be 11.02, 34.12, 544.45, and 1.6 Bq/kg, respectively. The concentrations of radionuclides were within the worldwide baseline, expect for 40K. The study concluded that both water sources are classified as very high salinity and sodium water (class C4-S4), and it cannot be used for irrigation, only suitable for the salt tolerant crops.

Opis:
Closely spaced CTD transects across the Słupsk Furrow displayed a ‘downward- bending’ of salinity contours below the salinity interface on the southern flank due to a transverse circulation in the saline water overflow. Numerical simulation of a gravity current in an idealized channel with geometry, dimensions and initial density stratification all much the same as in the Słupsk Furrow was applied to verify whether the downward-bending could be transformed into an inverted density stratification. Some arguments in favour of the possibility of convective overturning due to the differential transverse advection beneath the gravity current, brought on by the numerical simulations, are discussed.

Opis:
The purpose of this study was to assess progress in the implementation of rules for the control and handling of ballast water and sediments, regulated by the International Convention on the Control and Handling of Ship Ballast Water and Sediments (BWM Convention). The survey was conducted in 2018-2019 among seafarers responsible for handling ballast tanks. Analysis of the survey data revealed that despite the introduction of water treatments, ballast water continues to be a vector for the transfer of non-native organisms. This is due to the low effectiveness of the methods used, and the fact that 8% of the respondents answered that no BWT systems were used on the ships they manage. Despite this, some seafarers (4.7%) indicated that increasing environmental awareness and adherence to BWM principles should result in improved protection of aquatic ecosystems. Therefore, the global problem concerning the transport of non-native organisms via ballast water has still not been solved effectively. In the near future, improved BWT systems should be introduced, which after proper training of the crew will act as a barrier to the transfer of non-native organisms in ballast water.

Opis:
During August 2000 and February 2001 two cruises were carried out along the Egyptian Mediterranean Coast on the Egyptian r/v ‘El-Yarmouk’. The samples collected were used to study the ecology and distribution of hydromedusae and siphonophores during summer and winter. The density of hydromedusae was high in the inshore waters during summer (av. 71 org × 100 m−3), decreasing to 28 organisms per 100 m3 in the oceanic waters; in winter they were more abundant in the middle and offshore zones. Ato tal of 9 hydromedusae species were recorded during the present study, 8 of them in summer. The most common of these were Aglaura hemistoma, Olindias singularis, Liriope tetraphylla and Geryonia proboscidalis. Only 4 species were recorded during winter, including Cunina octonaria, which was not recorded during the summer. The nine species recorded in the present study are circumtropical. The siphonophore density was high in summer. In winter, the average standing crop of siphonophores fell to about 30% of that recorded in summer. 11 siphonophore species were recorded, 10 of them in summer; Cucullus campanula and Eudoxoides spiralis were the most common. Only 6 species were recorded in winter. These 11 species are widely distributed – they have been recorded from the Atlantic, Indian and Pacific Oceans. Strong seasonality is thus a striking feature of Egyptian Mediterranean waters. Temperature is the most variable factor affecting the planktonic community, fluctuating between 26.5 and 27◦C in summer and between 16.3 and 17.5◦C in winter. The western part of the Egyptian coast, the area under study in this work, is poorly diversified in comparison with the eastern part.

Opis:
The Baltic Sea is characterized by a seasonal variation of phytoplankton structure. These organisms are particularly sensitive to changes in various environmental parameters. Cyclic, recurring annually fluctuation of species composition, abundance and biomass of phytoplankton is a consequence of these changes. Spatial and temporal variability of particular groups of phytoplankton is not the same in different areas of the Baltic Sea. The purpose of this work was to determine the spatial and temporal distribution of phytoplankton in three chosen areas of the coastal zone of the southern Baltic Sea (Ustka, Poddąbie and Rowy) in the period of November 2014 - September 2016. Mean values of abundance and biomass of phytoplankton for the surveyed areas were typical for this type of coastal waters. In each of the surveyed areas the same dominat species in terms of the abundance and biomass were observed. A growth of diatoms was recorded only in the area of Ustka, which could have been caused by the inflow of river waters. Seasonal surveys of phytoplankton indicated that in the case of the studies regarding this parameter – taxonomic composition, abundance and biomass in the same surveyed area were similar at the three research stations (e.g. 75-80%), depending on the season of the year. On this basis, it was concluded that, whether carrying out the monitoring of phytoplankton or planned investments, the sample collection frequency had a greater significance than the number of research stations.
W Morzu Bałtyckim obserwuje się sezonowe zmiany struktury fitoplanktonu. Organizmy te są szczególnie wrażliwe na zmiany różnych parametrów środowiska. Konsekwencją tych zmian jest cykliczna, powtarzająca się co roku, fluktuacja składu gatunkowego, liczebności oraz biomasy fitoplanktonu. Przestrzenna i czasowa zmienność poszczególnych grup fitoplanktonu nie jest taka sama w różnych rejonach Bałtyku. Celem pracy było określenie struktury czasowo-przestrzennej występowania fitoplanktonu w trzech wybranych rejonach strefy przybrzeżnej południowego Bałtyku (Ustka, Poddąbie, Rowy) w latach listopad 2014 – wrzesień 2016. Średnie wartości liczebności i biomasy fitoplanktonu dla badanych rejonów były typowe dla tego rodzaju wód przybrzeżnych. W każdych z trzech badanych rejonów można zaobserwować te same dominanty w liczebności i biomasie. Jedynie w rejonie Ustka odnotowano wzrost okrzemek, co może być spowodowane napływem wód rzecznych. Sezonowe badania fitoplanktonu wykazały, że w przypadku badań tego parametru skład, liczebność i biomasa z tego samego rejonu badanego na trzech stacjach badawczych w zależności od pory roku jest podobna (np. w 75-80%). Na tej podstawie stwierdzono, iż wykonując badania monitoringowe fitoplanktonu czy pod planowane inwestycje większe znaczenie ma częstotliwość pobieranych próbek niż liczba stacji badawczych.

The organic matter production/respiration balance in the coastal water column was examined, both the primary production and community respiration being measured with the oxygen light-and-dark bottle method. Community respiration (CR) was always lower than the gross primary production (GPP) measured at a standard light intensity of 390 μE m−2 s−1, which amounted, on average, to 30% of GPP. During most of the in situ sampling period, the coastal system (6–7 m depth) was found to be autotrophic, with depth-integrated GPP ranging from 6.7 mmoles O2 m−2 d−1 in December to 214.2 mmoles O2 m−2 d−1 in August, and CR ranging correspondingly from 6.0 to 177.7 mmoles O2 m−2 d−1. However, on some occasions heterotrophic conditions were recorded: depth-integrated GPP

Opis:
Geographical words referring to water, such as river, stream sea or lake, have been used in language since the earliest. As water is considered essential for life in general, the names of water reservoirs and watercourses became popular and frequently used items in all languages. The present study is focused on the English names of natural water reservoirs (sea, lake) and watercourses (river, stream) and their regional spread in the 12th–15th centuries. The Old English names of watercourses and natural water reservoirs, sӕ, flod and ea, either survived in Middle English in a modified form or were (rarely) replaced by loanwords as the effect of the Norman Conquest of England in the 11th century. The research is concentrated on texts selected from the Innsbruck Corpus of Middle English Prose (Marcus 2008), with some material coming from the OED and MED. The analysis will show the extent of the loss of the original Anglo-Saxon words or their spread, frequently with a modified meaning. The analysis will also include the statistics of the terms in question in prose texts representing the chief dialects of the period. As regards the method, the present author makes use of the traditional semantic theories (e.g. Lyons 1977) and the prototype theory (e.g. Geeraerts 1997).

Opis:
The inherent optical properties (IOPs) of suspended particulate matter and their relations with the main biogeochemical characteristics of particles have been examined in the surface waters of the southern Baltic Sea. The empirical data were gathered at over 300 stations in open Baltic Sea waters as well as in the coastal waters of the Gulf of Gdańsk. The measurements included IOPs such as the absorption coefficient of particles, absorption coefficient of phytoplankton, scattering and backscattering coefficients of particles, as well as biogeochemical characteristics of suspended matter such as concentrations of suspended particulate matter (SPM), particulate organic matter (POM), particulate organic carbon (POC) and chlorophyll a (Chl a). Our data documented the very extensive variability in the study area of particle concentration measures and IOPs (up to two orders of magnitude). Although most of the particle populations encoun- tered were composed primarily of organic matter (av. POM/SPM=ca 0.8), the different particle concentration ratios suggest that the particle composition varied significantly. The relations between the optical properties and biogeochemical parameters of suspended matter were examined. We found significant variability in the constituent-specific IOPs (coefficients of variation (CVs) of at least 30% to 40%, usually more than 50%). Simple best-fit relations between any given IOP versus any constituent concentration parameter also highlighted the significant statistical errors involved. As a result, we conclude that for southern Baltic samples an easy yet precise quantification of particle IOPs in terms of the concentration of only one of the following parameters – SPM, POM, POC or Chl a – is not achievable. Nevertheless, we present a set of best statistical formulas for a rough estimate of certain seawater constituent concentrations based on relatively easily measurable values of seawater IOPs. These equations can be implemented in practice, but their application will inevitably entail effective statistical errors of estimation of the order of 50% or more.

Opis:
Archaeological work since 2014 in the Hellenistic areas of Berenike, a key port on Egypt’s Red Sea coast, founded by Ptolemy II Philadelphus in c. 275 BC, has brought extensive evidence of water-related structures: a rock-cut well located inside a rebuilt early-Hellenistic gate and a nearby cistern with an associated rainwater-collection system, that has changed the way in which the sources and uses of water in Hellenistic Berenike is understood today. The research started with the excavation of an ash mound, a characteristic landmark in the western part of the site, which is now believed to be the rubbish dump from the furnace that heated a Hellenistic bathhouse. At this stage in the research, it can be argued that Hellenistic Berenike had sufficient water available on site not only for drinking (hence potable), and agricultural and industrial uses, but also for public bathing. This article summarises the current state of research, presenting recent discoveries of a Hellenistic date at the site within their archaeological, architectural and environmental contexts.
