    Notes: Abstract During three expeditions with the RVs Meteor and Polarstern more than sixty thousand peracarids were sampled from the deep Arctic Ocean (northern North Atlantic) by means of an epibenthic sledge. Sampling areas were the Kolbeinsey Ridge north of Iceland (800–1100 m), the Northeast Water Polynya, off Greenland (45–517m), and 75°N east of Greenland (197–2681m). Until now 288 species of Peracarida have been identified to species level. These 288 species comprise 152 genera and 59 families of Amphipoda, Cumacea, Isopoda, Mysidacea and Tanaidacea. Thirty-eight genera were very frequent and were sampled at each expedition (these were 22 species of Isopoda, seven species of Cumacea, three species of Amphipoda and Mysidacea, each, and two species of Tanaidacea). Sixty genera are eurybathic, occurring at least over a depth range of 1000m, some even from the shelf up to 2681m depth. Only 10 genera are stenobathic, occurring only in the deep sea. No significant decrease in species number with depth or latitude could be observed. The influencing factors probably causing different community structures are diverse, ranging from food availability over substrate or hydrographical qualities to interspecific competition.

    Redescription of Echinomunna horrida Vanh\xc3\xb6ffen, 1914, a highly derived and rare species from the Antarctic (Crustacea, Isopoda, Munnidae) (1999)
    In:  Bulletin Zoologisch Museum vol. 17 no. 2, pp. 9-16
    Details
    Publication Date: 2024-01-12
    Description: During an expedition with RV Polarstern (1998) a male specimen of Echinomunna horrida was collected in the supranet of an epibenthic sledge in the Weddell Sea, Antarctica. Due to an incomplete and poor description by Vanh\xc3\xb6ffen (1914) a redescription is necessary on the basis of the male from the Weddell Sea and the female syntypes from the East Antarctic.

    Sphaeromatidae (Crustacea, Isopoda) of the Beagle Channel and description of Cymodopsis beageli n. sp (1998)
    In:  Beaufortia vol. 48 no. 7, pp. 137-161
    Details
    Publication Date: 2024-01-12
    Description: During an expedition with RV Victor Hensen (1994) and the RV Polarstern (1996) Isopoda Sphaeromatidae were collected in and off the eastern entrance of the Beagle Channel. The species found, Caecocassidias patagonica Kussakin, 1967, Cassidinopsis emarginata (Gu\xc3\xa9rin-M\xc3\xa9neville, 1843) and Moruloidea darwinii (Cunningham, 1871), were previously all poorly or insufficiently described; therefore a redescription is presented herein. Exosphaeroma gigas (Leach, 1818) was also collected frequently, but it was already redescribed earlier and thus only the localities are presented. Moreover, a new species, Cymodopsis beageli, n.sp., which is most closely allied to Cymodopsis sphyracephalata Hurley & Janssen, 1977, is described from the Beagle Channel.
