  6. Sea-floor videos and photographs (benthos) along 6 shelf profiles from the eastern Weddell Sea, Antarctica taken with remote operated vehicel CHEROKEE during Polarstern cruise ANT-XXI/2

    Gutt, Julian; Arntz, Wolf E; Dimmler, Werner; Schulz, Harald; Potthoff, Michael; Teixidó, Núria; Rose, Armin; Thatje, Sven
    The ROV operations had three objectives: (1) to check, whether the "Cherokee" system is suited for advanced benthological work in the high latitude Antarctic shelf areas; (2) to support the disturbance experiment, providing immediate visual Information; (3) to continue ecological work that started in 1989 at the hilltop situated at the northern margin of the Norsel Bank off the 4-Seasons Inlet (Weddell Sea). The "Cherokee" is was equipped with 3 video cameras, 2 of which support the operation. A high resolution Tritech Typhoon camera is used for scientific observations to be recorded. In addition, the ROV has a manipulator, a still...

  10. Sea-floor images from during POLARSTERN cruise ANT-XV/3 to the Weddell Sea, Antarctica

    Gutt, Julian; Teixidó, Núria
    Transects of a Remotely Operated Vehicle (ROV) providing sea-bed videos and photographs were carried out during POLARSTERN expedition ANT-XV/3 focussing on the ecology of benthic assemblages on the Antarctic shelf in the South-Eastern Weddell Sea. The ROV-system sprint 103 was equiped with two video- and one still camera, lights, flash-lights, compass, and parallel lasers providing a scale in the images, a tether-management system (TMS), a winch, and the board units. All cameras used the same main lense and could be tilted. Videos were recorded in Betacam-format and (film-)slides were made by decision of the scientific pilot. The latter were mainly...

  13. Sea-bed photographs (benthos) from the Weddell Sea along two ROV profiles during Polarstern cruise ANT-XIII/3

    Gutt, Julian
    Young specimens of cf. Pagothenia borchgrevinki were observed for the first time to cling to the subsurface of the marginal ice shelf in Drescher Inlet, southeastern Weddell Sea. Along an approximately 40-m-long videotransect at 80 m water depth, the abundance was roughly estimated to be 7 individuals per 10 m**2. This behaviour is interpreted to represent the most advanced adaptation to ice as a microhabitat for Antarctic fish.

  14. Mega-epibenthos at Bouvet Island (South Atlantic)

    Gutt, Julian; Fricke, Anna; Teixidó, Núria; Potthoff, Michael; Arntz, Wolf E
    Mega-epibenthic diversity was analysed using a seabed photography at four stations off Bouvet Island and one station at the Spiess Seamount in the South Atlantic. Surprisingly, the intermediate-scale diversity within the area of investigation was not lower compared to that on the Patagonian shelf and only moderately lower than that on the Antarctic continental shelf. This result is incompatible with Mac Arthur and Wilson's Island Biogeography Theory describing species richness as a function of immigration of new species into an area and its extension. The relatively high species number and the very small extension of the Bouvet shelf compared to...
