The benthic fauna off the Victoria-Land-Coast, Ross Sea (Antarctica) was investigated during the 19th Italica expedition in February 2004. Samples were taken along a latitudinal transect from Cape Adare down to Terra Nova Bay at water depths ranging from 84 to 515 m. A Rauschert dredge was used at 18 stations to collect epi- and infaunal macrobenthos. 9,494 specimens of Isopoda were collected, representing 19 families. Desmosomatidae were the most abundant family (35,297 ind/1,000 m2), followed by Paramunnidae (23,973 ind/1,000 m2). Paramunnidae was the most frequent taxon and was collected at all stations, in contrast to the Desmosomatidae, which did not occur at any station off Cape Adare.

    Exotopic protrusions were first recorded on zooplanktonic copepods of Lago Maggiore in 1992. They were classified into two types: (i) type I, the most abundant, dark, spherical and granular; (ii) type II, small, transparent and nongranular. They most commonly appeared on the lateral surface of...

    We examined deep-sea epibenthic sledge isopod data from the Atlantic sector of the Southern Ocean (SO) (depth range=742-5,191 m). Samples were taken during the expeditions EASIZ II (ANT XV-3) in 1998 and ANDEEP I and II (ANT XIX3/4) in 2002. A total of 471 isopod species were recorded from 28...

    The water level of Lake Balaton (a large, shallow lake) was extremely low in 2003, after a dry period of several years. Due to the intensive precipitation in 2004, a regeneration period commenced. Stones of the littoral zone were sampled near the water surface and from the lake bottom four times...

    Hyperspectral remote sensing has shown promise for detailed discrimination of coral reef substratum types, but, by necessity, it samples at pixel scales larger than reef substratum patch sizes. Spectral unmixing techniques have been successful in resolving subpixel areal cover in terrestrial...

    Several local surveys on the submerged vegetation have been conducted in past decades along the Finnish Baltic coastal areas. Surveys have been carried out by using various methods, which make the temporal comparisons of the results difficult. The need of a joint programme for coastal...

    Bank slopes, fronts between different basins, river estuaries, and sites in the vicinity of municipal wastewater discharges are the most productive areas of the Estonian coastal sea. In these areas macrozoobenthos biomass exceeded significantly the values of the adjacent sea. The concentration...
