title: Heat flow data during POLARSTERN cruise ARK-XVII/2, AMORE expedition to the Gakkel Ridge, with links to raw data files

description: The Gakkel Ridge in the Arctic Ocean with its adjacent Nansen and Amundsen Basins is a key region for the study of mantle melting and crustal generation at ultraslow spreading rates. We use free-air gravity anomalies in combination with seismic reflection and wide-angle data to compute 2-D crustal models for the Nansen and Amundsen Basins in the Arctic Ocean. Despite the permanent pack-ice cover two geophysical transects cross both entire basins. This means that the complete basin geometry of the world's slowest spreading system can be analysed in detail for the first time. Applying standard densities for the sediments and oceanic crystalline crust, the gravity models reveal an unexpected heterogeneous mantle with densities of 3.30 × 10³, 3.20 × 10³ and 3.10 × 10³ kg/m³ near the Gakkel Ridge. We interpret that the upper mantle heterogeneity mainly results from serpentinisation and thermal effects. The thickness of the oceanic crust is highly variable throughout both transects. Crustal thickness of less than 1 km dominates in the oldest parts of both basins, increasing to a maximum value of 6 km near the Gakkel Ridge. Along-axis heat flow is highly variable and heat flow amplitudes resemble those observed at fast or intermediate spreading ridges. Unexpectedly, high heat flow along the Amundsen transect exceeds predicted values from global cooling curves by more than 100%.

title: Results of nodule detection along AUV track SO239_19-1_AUV2 (Abyss_168) during SONNE cruise SO239

description: Images were acquired by the DeepSurvey Camera on board GEOMAR's AUV Abyss. Nodules were delineated by the CoMoNoD algorithm [see related to references]. Result files are computed per AUV dive. Nodule detections below 5cm^2 are neglected as are detections above 707cm^2. Abundance statistics are computed per m^2 and gridded per m^2 as well. For overlapping images, max-pooling has been applied to select the values reported in the result files. Pixel values in the rendered maps correspond to the units reported in the ASCI files (median-nodule-size: cm^2, nodule-number: m^-2, percent-coverage: %, sorting, skewness and pixel-contributions are unit-free).

title: Underway CO2 measurements for 2-day upwelling front experiment during METEOR cruise M93

description: * Gas molar fraction of CO2 (1-min means) was calibrated according to the procedure described in Arevalo-Martinez et al. (2013) and references therein. * Fugacities of CO2 in seawater (*_sw) and the overlying atmosphere (ca. 35 m asl, *_atm) are reported. * WindSpeed in m/s (measured at 35.3 m height)* Due to cloghing of the thermosalinograph's pump, no salinity data from this sensor was used. The salinity used is the mean of the calibrated values from the upper casts of ctd stations during M93. * Equilibration temperature was corrected by using the SST values from 6 m depth: TEQU = 0.9329(SST) + 1.955, r^2 = 0.827, n = 33447, norm. res. = 147.52.

title: Sampling information on lysianassoid amphipod crustaceans from the expedition PS82 (ANT-XXIX/9) to the Filchner area, Weddell Sea, Antarctica in 2013/2014

description: An integrative inventory, combining morphological identifications with DNA barcoding, of the amphipod scavenging fauna (Lysianassoidea) of the Filchner area in the south-eastern Weddell Sea is provided here. This understudied area, neighbouring the Filchner-Ronne Ice Shelf, represents a key oceanographic region for the global circulation but is, however, likely to be impacted by a myriad of consequences of warming waters. It also represents a biological hotspot and therefore, this area has been recently included as a candidate for a Marine Protected Area in the Southern Ocean (Weddell Sea MPA). Over 4400 lysianassoids were investigated for species richness and abundances at 20 different stations using different sampling devices, including the southernmost baited traps deployed so far (76°S). A high species richness was observed: 29 morphospecies of which five were new to science. Molecular species delimitation methods indicated the presence of 42 lineages; for four species, several (cryptic) lineages were found. More than 96% of the lysianassoids collected with a baited trap belonged to the species Orchomenella pinguides s.l. The diversity of the amphipod scavenger guild in this ice-bound ecosystem of the Weddell Sea is discussed in the light of bottom-up selective forces. Harbouring spawning and nursery grounds for silverfish and icefishes, which are preyed upon by seal species, abundant fish and mammalian food falls are likely to represent the major food for scavengers in this southernmost part of the Weddell Sea. Finally, the importance of such biodiversity surveys to better understand the ecological role of scavengers in this system is highlighted.
