title: Tab. 1: Summary of available data about antifreeze peptides of polar fish

description: In the blood of Antarctic notothenioid and Arctic gadiform fishes, freezing is inhibited by antifreeze glycopeptide macromolecules (AFGP). These antifreeze molecules are built up of repeating tripeptide units (Ala-Ala-Thr)n, to which the disaccharide fl-D-galactosyl-(1-&gt;3)a-N-acetyl-D-galactosamine is linked through the hydroxyl oxygen of the threonyl residue. Species of Liparididae, Zoarcidae, Cottidae and Pleuronectidae synthezise only unglycosylated antifreeze peptides (AFP). It could be demonstrated for the Antarctic silverfish Pleuragramma antarcticum that the synthesis of AFGP is not constitutive but rather regulated by water temperature. Moreover a novel glycopeptid was isolated and characterised from P. antarcticum, the Pleuragramma-antifreeze glycopeptid (PAGP). The level of antifreeze concentration was dependent on the ambient water temperature, the depth of distribution, the life cycle and the evolution of the species. Surprisingly, detectable AFGPs in perciform fish of the Antarctic and gadiform fish of the Arctic and Antarctic could illustrate, that before the continental drift occurred a precursor glycopeptid existed, and that the existence of freezing resistance in some species reflects the past glaciation. The wide distribution and high heterogeneity of AFPs point to the assumption that these peptides are results of cold shock stress responses.

title: Basic measurements of radiation from the Baseline Surface Radiation Network (BSRN), stations De Aar, Sede Boquer and Tamanrasset, reference list of 224 datasets

description: Financing Concentrating Solar Power (CSP) projects is highly dependent on plant performance. Yields of CSP plants depend strongly on site-specific meteorological conditions. Meteorological parameters that can influence the performance of CSP plants are Direct Normal Irradiance (DNI), wind, ambient air temperature, and humidity. The sensitivity study shows that DNI is the parameter with highest influence on energy yield of CSP plants. However, the annual sum or average of DNI is often thought as the value giving already a good indicator for Annual Energy Production (AEP) of CSP plants. This thesis is proven wrong, as the study finds that for years with same DNI annual averages AEP could vary as much as ± 9 % due to differences in DNI frequency distribution. Further the beneficial effect of lower latitudes is not expressed in the long-term average of DNI. For parabolic trough plants it is found that with a 10° increase in latitude, decrease in the ratio of AEP to DNI could be around 10 % for the Northern Hemisphere. Due to less favourable irradiance during winter the effect is even stronger for the Southern Hemisphere and is around 14 % per 10° of latitude, which often is counterbalanced by higher DNI annual averages compared to the Northern hemisphere. Keywords: Concentrating Solar Power (CSP), solar resource, Direct Normal Irradiance, DNI frequency distribution, plant performance, influence, latitude-effect, ambient meteorological conditions.

title: (Table 2) Production parameters of phytoplankton and some associated parameters in the area of the Titanic Polygon

description: Studies were carried out mostly in the area of RMS Titanic wreck site (41°44'N, 49°57'W) located above the continental slope and the south of the Grand Banks of Newfoundland. In a period from 18.06 to 24.09.2001 five surveys of production characteristics of surface phytoplankton were conducted over 5-9 days. Mean values of these characteristics obtained during the surveys were 9.2-11.7 mg C/m**3 per day for primary production (C_phs), 0.102-0.188 mg/m**3 for chlorophyll a (C_chls), and 4.44-7.42 mg C/mg chl. a per hour for assimilation number (AN). The main reason for low C_phs variability was a significant inverse relationship (R=-0.66) between AN and C_chls found over the research area. When cold shelf waters dominated in the area (27.07 to 19.08.2001), C_chls values for the slope region (0.125+/-0.031 µg/l) and for the outer shelf (0.130+/-0.040 µg/l) were similar. During strengthening of influence of warmer slope waters within area (from 29.08 to 13.09.2001), C_chls concentration within surface waters of the outer shelf was 0.152+/-0.039 µg/l and exceeded one for the slope region (0.094+/-0.004 µg/l) by factor 1.6. Against the background of low Cchls values, the High values of integral primary production in the water column (510-1010 mg C/m**2 per day) at low C_chls values measured within the area were determined both by high assimilation activity of phytoplankton and by the deep (30-40 m) maximum of primary production. Main reasons for formation of such a maximum were high chlorophyll concentration within the layer of the deep chlorophyll maximum (up to 0.5-2.5 µg/l) and in the relatively high solar irradiance within this layer varying from 1.4 to 8.6% of subsurface PAR.

title: Tab. 1+2: Representative electron-microprobe analyses of minerals from Du Toit Nunataks

description: An example of cordierite-bearing gneiss that is part of a high-grade gneiss-migmatite sequence is described from the Hatch Plain in the Read Mountains of the Shackleton Range, Antarctica, for the first time. The cordierite-bearing rocks constitute the more melanosomic portions of the metatectic and migmatitic rocks that are associated with relict granulite facies rocks such as enderbitic granulite and enderbitic garnet granulite. The predominant mineral assemblage in the cordierite-bearing rocks is chemically homogeneous cordierite (XMg 0.61) and biotite (XMg 0.47), strongly zoned garnet (XMg 0.18-0.11), sillimanite, K-feldspar (Or81-94Ab5-18An0.6), plagioclase (An28), and quartz. Inclusions of sillimanite and biotite relics in both garnet and cordierite indicate that garnet and cordierite were produced by the coupled, discontinuous reaction biotite + sillimanite + quartz = cordierite + garnet + K-feldspar + H2O.Various garnet-biotite and garnet-cordierite geothermometers and sillimanite-quartz-plagioclase-garnet-cordierite geobarometers yield a continuous clockwise path in the P-T diagram. The P-T conditions for equilibrium between garnet core and cordierite and between garnet core and biotite during peak metamorphism and migmatization were estimated to be 690 °C at 5-6 kb. This was followed by cooling and unloading with continuously changing conditions down to 515 °C at 2-3 kb. This low-pressure re-equilibration correlates with the pressure conditions evaluated by SCHULZE (1989) for the widespread granitic gneisses of the Read Group in the Shackleton Range. The associated relict enderbitic granulites representing low-pressure type granulite (8 kb; 790 °C) are comparable to similar low-pressure granulites from the East Antarctic craton. They were either formed by under-accretion processes after collision (WELLS 1979, p. 217) or they are a product of remetamorphism at P-T conditions intermediate between granulite and amphibolite facies. A model of a multiple imbrication zone with crustal thickening (CUTHBERT et al. 1983) is discussed for the formation of the relict granulites of the central and eastern Read Mountains which show higher pressure conditions (8-12 kb, SCHULZE & OLESCH 1990), indicating a Proterozoic crustal thickness of at least 40 km.

title: (Table 2) Taxonomic composition of diatoms in dredged samples from the island-side slope of the Kuril-Kamchatka Trench

description: Studies of diatoms from dredge samples collected on the island slope of the Kuril-Kamchatka Trench have allowed to recognize well-preserved marine diatom assemblages corresponding to assemblages of the followed Oligocene zones: Rhizosolenia oligocaenica (subzone ''a'', 33.6-31 Ma), Cavitatus rectus (29.6-28.2 Ma), and Rocella gelida (28.2-24.0 Ma) as identified in the North Pacific zonal scale. Description of these assemblages and their complete taxonomic composition are presented. Diversity of species together with abundance and degree of preservation of diatoms and accompanying siliceous microorganisms suggests their autochtonous origin and favorable conditions of their development. Assemblages of the Early Oligocene zones Rhizosolenia oligocaenica and Cavitatus rectus recognized in sediments of the outer zone of the Lesser Kuril Ridge (submarine slope of the Shikotan Island) and on the Vityaz' submarine ridge were most probably formed under conditions of a vast shelf, while assemblage of the Late Oligocene zone Rocella gelida encountered only in the region of the Lesser Kuril Ridge formed under more deep-water conditions, presumably, over an island slope. Deepening of the basin in the region of the outer zone of the Lesser Kuril Ridge in Late Oligocene probably reflects one of stages of evolution of the Kuril-Kamchatka Trench.

title: Wet biomass of the main mesoplankton groups in the Guaymas Basin (Gulf of California) measured in October 1990

description: Plankton above the vent fields of the Guaymas Basin was studied over the entire water column with the use of the MIR deep-sea manned submersible and BR plankton nets. Our studies confirmed that there is a certain increase in zooplankton biomass in the near-bottom layers. A reason for this phenomenon is not clear, but it may be related either to concentration of food particles precipitating from highly-productive surface waters, or to the effect of changes in concentration of dissolved oxygen or to the influence of hydrothermal production. This paper also deals with influence of the oxygen minimum layer at depth of 450-800 m on plankton.

title: Abundance and size composition of ctenophore Mnemiopsis leidyi population in the Caspian Sea on 2001-06-24 to 2001-07-01

description: Abundance and size distribution of ctenophore Mnemiopsis leidyi in different parts of the Caspian Sea were studied in summer 2001 in relation to environmental conditions. In general, principal differences were found in M. leidyi abundance and population reproduction activity in northern-, middle- and southern Caspian waters. Ctenophore was practically absent in the northern Caspian. In the west of the middle Caspian Sea it penetrated far to the north demonstrating low reproduction activity. In the east the first single comb jellies were pointed out only in the most south of the region. In the warmest and most productive southern part of the Caspian Sea several zones of M. leidyi active breeding were found with total abundance exceeding 6000 #/m**2. Breeding activity and abundance of ctenophores increased here from the east to the west exceeding maximum values along the western coast of the southern Caspian Sea in regions of intensive sprat catching. Dependence of M. leidyi population development on temperature conditions was mentioned. On the base of remote sensed surface temperature, chlorophyll, and suspended mater distribution analysis possible ctenophore settling mechanisms by mesoscale dynamic structures were examined. Practical applications of obtained results are discussed for using effective biological methods to prevent catastrophic consequences of M. leidyi invasion to the Caspian Sea.
