    This dataset of radio-echo sounding internal reflecting horizons (IRH) which were traced across the radar surveys conducted in the 2019/20 Antarctic summer season at Little Come C, in the Dome C region of the East Antarctic Plateau. The data set is associated to publication: Chung, A., et al. (in review). The data were collected during a radar survey conducted in the Antarctic field seasons of 2019-20 using the Little Dome C - Very High Frequency (LDC-VHF) multichannel coherent radar depth sounder developed through a collaboration of The University of Alabama (UA), the University of Copenhagen (CPH) and the Alfred Wegener Institute (AWI). The survey covered Patches A and B of Little Dome C (Lilien et al., 2021), in order to select the exact drill site for the Beyond EPICA Oldest Ice drilling project. The datasets consists of 12 transects systematically covering Patches A and B with parallel lines, over an area of approximately 5×8 km^2. The dataset contains 19 IRHs, the basal unit horizon and the ice-bed interface which were manually traced by Ailsa Chung, using the seismic environment of the Echos software from Paradigm Geophysical. A single file for each IRH is provided in a text file, tab separated format with both depth and two-way travel time. The conversion to depth done using c = 0.1685 m/μs and firn correction of 10 m. The IRHs are provided at approximately 3.5 m spacial resolution.

    During the Transatlantic Equatorial Cruise II (TRATLEQ II) with the R/V METEOR (M181) from 17. April to 28. May 2022 (Brandt, 2022), 44 Lagrangian drifters were deployed along the Equator (between 7°W and 37°W) to monitor the surface flow in the upper meter. The equatorial section covered the region of the Atlantic cold tongue that seasonally develops during boreal summer east of 23°W and the western equatorial Atlantic characterized by warmer surface waters and deeper mixed layer depths. In particular, the cruise M181 took place during the warm phase with relatively homogeneous warm surface layer in the whole equatorial Atlantic. Drifters were deployed every 1° longitude (~111 km) between 7°W and 37°W. The drifters were designed and built at Helmholtz-Zentrum Hereon to follow the upper surface flow (approx. 50 cm). The main body of these Hereon drifters consists of a 7.5 cm x 20 cm long tube with a floatation ring at the top. It is attached to a drogue of 35 cm in both length and diameter through a flexible cord within a distance of 20 cm to the tube. When deployed about 5 cm of the tube protrude from the water surface, resulting in a ratio of drag area inside to drag area outside the water of 21. The tube contains a battery pack and an electronic board, which acquires and reports the GPS position every 5 minutes via a global satellite network in near real time. Table 1 provides some information on the 44 deployed Hereon Drifters, which consists of deployment and working time, total covered distance and number of recorded GPS positions.

    The copepods' impact on vertical carbon flux was assessed for stratified depth layers down to 2000 m at six stations along a transect between 24°N and 21°S in the eastern Atlantic Ocean in October/November 2012. Total copepod community consumption ranged from 202-604 mg C m⁻² day⁻¹, with highest ingestion rates in the tropical North Atlantic. Calanoids consumed 75-90% of the particulate organic carbon (POC) ingested by copepods, although the relative contribution of cyclopoids (mostly Oncaeidae) increased with depth. Net ingestion (=consumption - fecal pellet egestion) of POC varied from 106-379 mg C m⁻² day⁻¹ for calanoids and 37-51 mg C m⁻² day⁻¹ for cyclopoids, corresponding to 16-58% and 5-9%, respectively, of primary production (PP). In total, 9-33% and 2-5% of PP were respired as inorganic carbon by calanoids and cyclopoids, respectively. Copepod ingestion was highly variable between stations and depth layers, especially in the epi- and upper mesopelagic zone. Diel vertical migrants such as Pleuromamma enhanced the vertical flux to deeper layers, particularly in the region influenced by the Benguela Current. The impact of copepod communities on POC flux decreased below 1000 m and POC resources reaching the bathypelagic zone were far from being fully exploited by copepods. As key components, copepods are important mediators of carbon fluxes in the ocean. Their biomass, community composition and interactions strongly affect the magnitude of organic carbon recycled or exported to deeper layers. High variability, even at smaller vertical scales, emphasizes the complex dynamics of the biological carbon pump.

    Authors: Cárdenas, Paco; Moore, Jon A;

    We report the first records of the sponge genus Geodia (Demospongiae, Tetractinellida, Geodiidae) from the New England Seamounts and Muir Seamount, at lower bathyal depths. Nine specimens collected between 2000 and 2005 belong to two boreal species (Geodia macandrewii and Geodia barretti) and a temperate species (Geodia megastrella). These records extend the distributions of these deep-sea amphi-Atlantic species to the west. Most of these specimens were originally fixed in formalin, which substantially degraded the DNA. We nonetheless managed to sequence two cytochrome c oxidase subunit I (COI) mini-barcodes: the universal mini-barcode at the 5' end of the Folmer barcode (130 bp) and a newly proposed mini-barcode at the 3' end of the Folmer barcode (296 bp). These mini-barcodes unambiguously confirmed our identifications. As an additional test, we also successfully sequenced these two mini-barcodes from the holotype of G. barretti, collected in 1855. We conclude by advocating the use of mini-barcodes on formalin-fixed or old specimens with degraded DNA. Supplement to: Cárdenas, Paco; Moore, Jon A (2017): First records of Geodia demosponges from the New England seamounts, an opportunity to test the use of DNA mini-barcodes on museum specimens. Marine Biodiversity, 12 pp This dataset gives the collecting information of New England Seamount Geodia species from the Yale Peabody Museum. Museum numbers, fixation processing and Genbank accession numbers are also given.

    Dielectric permittivity (ε′) and dielectric loss (ε″) measurements were made of discrete snow layers and at fixed vertical intervals. Measurements were made using the Stevens Water Monitoring Systems Hydra Probe (a.k.a. hydraprobe). The hydraprobe uses a tine assembly consisting of a central waveguide and three outer rods, each 4.5 cm in length and 3 mm wide, to measure the impedance of the sample at 50 MHz over a cylindrical area of 5.7 cm in length by 3 cm in diameter. The sensor was calibrated using isopropyl alcohol for ε' (±0.6 %) and a saline solution of known conductivity for ε'' (±0.7 %). Samples were obtained by horizontally inserting the probe tines into the snow, at a given layer/interval (every 3cm), to their maximum depth and collecting a response. 0 cm is the snow-ice interface. For related temperature and density measurements see https://doi.pangaea.de/10.1594/PANGAEA.940200 and https://doi.pangaea.de/10.1594/PANGAEA.940214 in this bundled dataset.

    This dataset of radio-echo sounding internal reflecting horizons (IRH) which were traced across the radar surveys conducted in the 2019/20 Antarctic summer season at Little Come C, in the Dome C region of the East Antarctic Plateau. The data set is associated to publication: Chung, A., et al. (in review). The data were collected during a radar survey conducted in the Antarctic field seasons of 2019-20 using the Little Dome C - Very High Frequency (LDC-VHF) multichannel coherent radar depth sounder developed through a collaboration of The University of Alabama (UA), the University of Copenhagen (CPH) and the Alfred Wegener Institute (AWI). The survey covered Patches A and B of Little Dome C (Lilien et al., 2021), in order to select the exact drill site for the Beyond EPICA Oldest Ice drilling project. The datasets consists of 12 transects systematically covering Patches A and B with parallel lines, over an area of approximately 5×8 km^2. The dataset contains 19 IRHs, the basal unit horizon and the ice-bed interface which were manually traced by Ailsa Chung, using the seismic environment of the Echos software from Paradigm Geophysical. A single file for each IRH is provided in a text file, tab separated format with both depth and two-way travel time. The conversion to depth done using c = 0.1685 m/μs and firn correction of 10 m. The IRHs are provided at approximately 3.5 m spacial resolution.

    During the Transatlantic Equatorial Cruise II (TRATLEQ II) with the R/V METEOR (M181) from 17. April to 28. May 2022 (Brandt, 2022), 44 Lagrangian drifters were deployed along the Equator (between 7°W and 37°W) to monitor the surface flow in the upper meter. The equatorial section covered the region of the Atlantic cold tongue that seasonally develops during boreal summer east of 23°W and the western equatorial Atlantic characterized by warmer surface waters and deeper mixed layer depths. In particular, the cruise M181 took place during the warm phase with relatively homogeneous warm surface layer in the whole equatorial Atlantic. Drifters were deployed every 1° longitude (~111 km) between 7°W and 37°W. The drifters were designed and built at Helmholtz-Zentrum Hereon to follow the upper surface flow (approx. 50 cm). The main body of these Hereon drifters consists of a 7.5 cm x 20 cm long tube with a floatation ring at the top. It is attached to a drogue of 35 cm in both length and diameter through a flexible cord within a distance of 20 cm to the tube. When deployed about 5 cm of the tube protrude from the water surface, resulting in a ratio of drag area inside to drag area outside the water of 21. The tube contains a battery pack and an electronic board, which acquires and reports the GPS position every 5 minutes via a global satellite network in near real time. Table 1 provides some information on the 44 deployed Hereon Drifters, which consists of deployment and working time, total covered distance and number of recorded GPS positions.

    The copepods' impact on vertical carbon flux was assessed for stratified depth layers down to 2000 m at six stations along a transect between 24°N and 21°S in the eastern Atlantic Ocean in October/November 2012. Total copepod community consumption ranged from 202-604 mg C m⁻² day⁻¹, with highest ingestion rates in the tropical North Atlantic. Calanoids consumed 75-90% of the particulate organic carbon (POC) ingested by copepods, although the relative contribution of cyclopoids (mostly Oncaeidae) increased with depth. Net ingestion (=consumption - fecal pellet egestion) of POC varied from 106-379 mg C m⁻² day⁻¹ for calanoids and 37-51 mg C m⁻² day⁻¹ for cyclopoids, corresponding to 16-58% and 5-9%, respectively, of primary production (PP). In total, 9-33% and 2-5% of PP were respired as inorganic carbon by calanoids and cyclopoids, respectively. Copepod ingestion was highly variable between stations and depth layers, especially in the epi- and upper mesopelagic zone. Diel vertical migrants such as Pleuromamma enhanced the vertical flux to deeper layers, particularly in the region influenced by the Benguela Current. The impact of copepod communities on POC flux decreased below 1000 m and POC resources reaching the bathypelagic zone were far from being fully exploited by copepods. As key components, copepods are important mediators of carbon fluxes in the ocean. Their biomass, community composition and interactions strongly affect the magnitude of organic carbon recycled or exported to deeper layers. High variability, even at smaller vertical scales, emphasizes the complex dynamics of the biological carbon pump.
