description: The dataset comprises a total of 336 records of abundance and biomass of two sea urchin species, Sterechinus antarcticus Koehler, 1901 and Sterechinus neumayeri (Meissner, 1900), from 67 trawls (Agassiz trawl, bottom trawl or dredge), 56 photo sessions (see doi link to photographs in dataset) and three other samples (multi-box corer, giant box corer, weir basket). The data were collected on the eastern and southern shelf and slope of the Antarctic Weddell Sea (depth range: 97 - 1243 m) during "Polarstern" cruises ANT I/2 (1983), ANT II/4 (1984), ANT III/3 (1985), ANT V/3 (1986), ANT V/4 (1987), ANT VI/3 (1988) and ANT VII/4 (1989).

title: Cloudnet IWC during POLARSTERN cruise PS106

description: The dataset contains daily nc-files of the Cloudnet ice water content during Polarstern cruise PS106 based on:- 35.5 GHz Cloud radar MIRA.The data is retrieved using the instrument synergystic approach Cloudnet (Illingworth, 2007, doi:10.1175/BAMS-88-6-883).This variable was calculated from the 35.5-GHz radar reflectivity factor after correction for gaseous attenuation, and temperature taken from a forecast model, using the following empirical formula:log10(iwc[g m-3]) = 0.000242Z[dBZ]T[degC] + 0.0699Z[dBZ] + -0.0186T[degC] + -1.63 (Hogan, 2006, doi:10.1175/JAM2340.1).In this formula Z is taken to be defined such that all frequencies of radar would measure the same Z in Rayleigh scattering ice. However, the radar is more likely to have been calibrated such that all frequencies would measure the same Z in Rayleigh scattering liquid cloud at 0 degrees C. The measured Z is therefore multiplied by|K(liquid,0degC,35GHz)|^2/0.93 = 0.9441before applying this formula.The formula has been used where the \"categorization\" data has diagnosed that the radar echo is due to ice, but note that in some cases supercooled drizzle will erroneously be identified as ice. Missing data indicates either that ice cloud was present but it was only detected by the lidar so its ice water content could not be estimated, or that there was rain below the ice associated with uncertain attenuation of the reflectivities in the ice.Note that where microwave radiometer liquid water path was available it was used to correct the radar for liquid attenuation when liquid cloud occurred below the ice; this is indicated a value of 3 in the iwc_retrieval_status variable. There is some uncertainty in thisprodedure which is reflected by an increase in the associated values in the iwc_error variable.When microwave radiometer data were not available and liquid cloud occurred below the ice, the retrieval was still performed but its reliability is questionable due to the uncorrected liquid water attenuation. This is indicated by a value of 2 in the iwc_retrieval_status variable, and an increase in the value of the iwc_error variable.

title: Demersal fish assemblages in the southeastern Weddell Sea

description: Our knowledge on distribution, habitats and behavior of Southern Ocean fishes living at water depths beyond scuba-diving limits is still sparse, as it is difficult to obtain quantitative data on these aspects of their biology. Here, we report the results of an analysis of seabed images to investigate species composition, behavior, spatial distribution and preferred habitats of demersal fish assemblages in the southern Weddell Sea. Our study was based on a total of 2736 high-resolution images, covering a total seabed area of 11,317 m2, which were taken at 13 stations at water depths between 200 and 750 m. Fish were found in 380 images. A total of 379 notothenioid specimens were recorded, representing four families (Nototheniidae, Artedidraconidae, Bathydraconidae, Channichthyidae), 17 genera and 25 species. Nototheniidae was the most speciose family, including benthic species (Trematomus spp.) and the pelagic species Pleuragramma antarctica, which was occasionally recorded in dense shoals. Bathydraconids ranked second with six species, followed by artedidraconids and channichthyids, both with five species. Most abundant species were Trematomus scotti and T. lepidorhinus among nototheniids, and Dolloidraco longedorsalis and Pagetopsis maculatus among artedidraconids and channichthyids, respectively. Both T. lepidorhinus and P. maculatus preferred seabed habitats characterized by biogenous debris and rich epibenthic fauna, whereas T. scotti and D. longedorsalis were frequently seen resting on fine sediments and scattered gravel. Several fish species were recorded to make use of the three-dimensional structure formed by epibenthic foundation species, like sponges, for perching or hiding inside. Nesting behavior was observed, frequently in association with dropstones, in species from various families, including Channichthyidae (Chaenodraco wilsoni and Pagetopsis macropterus) and Bathydraconidae (Cygnodraco mawsoni).

title: A seismic refraction and wide-angle reflection profile M111 - DY-05 during METEOR cruise M111 in the Ionian Sea, with links to SGY data files

description: During RV Meteor cruise M111 refraction and wide-angle reflection seismic data were acquired. We present eight seismic record sections (.sgy format) of the hydrophone components from four ocean bottom hydrophones (OBH501, OBH503, OBH505, OBH507) and four ocean bottom seismometers (OBS502, OBS504, OBS506, OBS508) along the NNE-SSW oriented seismic profile DY-05, which is situated in the Ionian Abyssal Plain. The profile stretches over a distance of 131 km and was shot using an airgun array of six G-gun clusters with a total volume of 84 l (5440 cu in) at 210 bar. A total of 946 shots were fired every 60 s (~140 m) with an airgun towed behind the vessel in a depth of 8 m. Data are unprocessed, however, they are corrected for instrument drift along the profile using the symmetry of the direct arrival and the data are time corrected.

title: Cloudnet categorization during POLARSTERN cruise PS106

description: The dataset contains daily nc-files of the Cloudnet target categorization during Polarstern cruise PS106. The data is retrieved using the instrument synergystic approach Cloudnet (Illingworth, 2007 doi:10.1175/BAMS-88-6-883 ). This dataset is an aggregation of data from cloud radar, lidar, a numerical forecast model and optionally a rain gauge and microwave radiometer. It is intended to facilitate the application of synergistic cloud-retrieval algorithms by performing a number of the preprocessing tasks that are common to these algorithms. Each of the observational datasets has been interpolated on to the same grid, although the model data are provided on a reduced height grid. Radar reflectivity has been corrected for attenuation, where possible, and two additional fields have been added: \"category_bits\" contains a categorization of the targets in each pixel and \"quality_bits\" indicates the quality of the data at each pixel. Finally, estimates of the random and systematic errors in reflectivity factor and attenuated backscatter are provided.
