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:
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:
Two Spitsbergen fjords, Hornsund and Kongsfjorden, are known for being under different hydrological regimes. The first is cold, separated from warm Atlantic water by East Spitsbergen Current, while Kongsfjorden is frequently penetrated by relatively warm Atlantic water. On the other hand, both are under strong influence of water discharge from glaciers and land freshwater input. During the period of observation in both fjords a dominant water mass was Surface Water, which originates mainly from glacial melt. The presence of suspended matter introduced with melt water in Surface Water is reflected by highest values of light attenuation and absorption coefficients recorded in areas close to glacier both in Hornsund and Kongsfjorden. In Hornsund the maximum light attenuation coefficient cpg(555) was 5.817 m−1 and coefficient of light absorption by particles ap(676) = 0.10 m−1. In Kongsfjorden the corresponding values were 26.5 m−1 and 0.223 m−1. In Kongsfjorden suspended matter of the size class 20–200 μm dominated over fractions smaller than 20 μm while in Hornsund dominating size fraction was 2–20 μm. The results provide an evidence of considerable range of variability of the optical properties mainly due to glacial and riverine runoff. The scale of variability of particulate matter in Kongsfjorden is bigger than in Hornsund. Most of the variability in Hornsund can be attributed to glaciers discharge and a presence of particles of mineral origin, while in Kongsfjorden the organic and mineral particles contribute almost equally to defining the optical properties of water.
