The taxonomy of six species and one subspecies of Natatolana, which have previously been recorded from the north Atlantic Ocean and Mediterranean Sea, is reviewed. Natatolana caeca, N. gallica, N. gracilis and N. neglecta are redescribed from the type material. The location of possible type material of N. borealis is reported and a redescription of this species is provided, based on material from the type locality. Natatolana neglecta var. imicola is recognized as a valid species. Natatolana schtnidti is regarded as a junior synonym of N. imicola based on comparison of type material and this material is used to redescribe the species. Distribution records for these species are summarized from examination of material held in various collections and a key to separate these species is provided.

Abstract. The spatial and temporal variability of extreme wave climate in the North Atlantic Ocean and the Mediterranean Sea is assessed using a 31-year wave model hindcast. Seasonality accounts for 50 % of the extreme wave height variability in the North Atlantic Ocean and up to 70 % in some areas of the Mediterranean Sea. Once seasonality is filtered out, the North Atlantic Oscillation and the Scandinavian index are the dominant large-scale atmospheric patterns that control the interannual variability of extreme waves during winters in the North Atlantic Ocean; to a lesser extent, the East Atlantic Oscillation also modulates extreme waves in the central part of the basin. In the Mediterranean Sea, the dominant modes are the East Atlantic and East Atlantic–Western Russia modes, which act strongly during their negative phases. A new methodology for analyzing the atmospheric signature associated with extreme waves is proposed. The method obtains the composites of significant wave height (SWH), mean sea level pressure (MSLP), and 10 m height wind velocity (U10) using the instant when specific climatic indices have a stronger correlation with extreme waves.

Abstract. During scanning electron microscope investigations of living coccolithophorids from the Mediterranean Sea and the North Atlantic Ocean, two hitherto undescribed species of the genus Syracosphaera Lohmann, 1902 emend. Gaarder (in Gaarder and Heimdal, 1977) were found. The first species, Syracosphaera noroiticus sp. nov., was recorded in the Gulf of Lyons (Mediterranean Sea), and the second, S. marginaporata sp. nov., was found in the eastern North Atlantic.
