    Presence-absence records for four cold-water coral taxa on the seamounts of Cabo Verde (NW Africa) (2023)
    PANGAEA
    Details
    Publication Date: 2024-06-01
    Description: Presence-absence records for four cold-water coral (CWC) taxa (Enallopsammia rostrata, Acanella arbuscula, Metallogorgia spp. and Paramuricea spp.) were gathered to conduct distribution models on seamounts (Cadamosto, Nola, Senghor and Cabo Verde) of the Cabo Verde archipelago (NW Africa), covering a bathymetric range from 2100 to 750 m water depth. Data were extracted from video footage collected with Remotely Operated Vehicles during the M80/3 Meteor (2010) and the iMirabilis2 (2021) research expeditions. Video data from the iMirabilis2 expedition was analysed, quantitively, using the open-source software BIIGLE (Langenkämper et al. 2017). Observations from five continuous 1 to 2 km-long video transects between 2000 and 1400 m depth at Cadamosto Seamount were converted into presence-absence data points. Similar data were not available for the seamounts explored during M80/3 Meteor. However, all the available images and short video clips from that expedition were analysed to identify presence and absence points for each of the four target CWC taxa. All the available presence/absence data from the two expeditions was transformed into one point per grid cell of a 100 m resolution bathymetry grid, with the prevalence of the presence records over the absence records, in grid cells where both categories overlapped.

    Exploring Prokaryotic Communities in the Guts and Mucus of Nudibranchs, and Their Similarity to Sediment and Seawater Microbiomes (2023)
    In:  Current Microbiology vol. 80 no. 294
    Details
    Publication Date: 2024-05-31
    Description: In the present study, we compared mucus and gut-associated prokaryotic communities from seven nudibranch species with sediment and seawater from Thai coral reefs using high-throughput 16S rRNA gene sequencing. The nudibranch species were identified as Doriprismatica atromarginata (family Chromodorididae), Jorunna funebris (family Discodorididae), Phyllidiella nigra, Phyllidiella pustulosa, Phyllidia carlsonhoffi, Phyllidia elegans, and Phyllidia picta (all family Phyllidiidae). The most abundant bacterial phyla in the dataset were Proteobacteria, Tenericutes, Chloroflexi, Thaumarchaeota, and Cyanobacteria. Mucus and gut-associated communities differed from one another and from sediment and seawater communities. Host phylogeny was, furthermore, a significant predictor of differences in mucus and gut-associated prokaryotic community composition. With respect to higher taxon abundance, the order Rhizobiales (Proteobacteria) was more abundant in Phyllidia species (mucus and gut), whereas the order Mycoplasmatales (Tenericutes) was more abundant in D. atromarginata and J. funebris. Mucus samples were, furthermore, associated with greater abundances of certain phyla including Chloroflexi, Poribacteria, and Gemmatimonadetes, taxa considered to be indicators for high microbial abundance (HMA) sponge species. Overall, our results indicated that nudibranch microbiomes consisted of a number of abundant prokaryotic members with high sequence similarities to organisms previously detected in sponges.

    The annelid community of a natural deep-sea whale fall off eastern Australia (2023)
    Australian Museum
    In:  Records of the Australian Museum vol. 75 no. 3, pp. 167-213
    Details
    Publication Date: 2024-05-31
    Description: n the deep ocean, whale falls (deceased whales that sink to the seafloor) act as a boost of productivity in this otherwise generally food-limited setting, nourishing organisms from sharks to microbes during the various stages of their decomposition. Annelid worms are habitual colonizers of whale falls, with new species regularly reported from these settings and their systematics helping to resolve biogeographic patterns among deep-sea organic fall environments. During a 2017 expedition of the Australian research vessel RV Investigator to sample bathyal to abyssal communities off Australia’s east coast, a natural whale fall was opportunistically trawled at ~1000 m depth. In this study, we provide detailed taxonomic descriptions of the annelids associated with this whale-fall community, using both morphological and molecular techniques. From this material we describe nine new species from five families (Dorvilleidae: Ophryotrocha dahlgreni sp. nov. Ophryotrocha hanneloreae sp. nov., Ophryotrocha ravarae sp. nov.; Hesionidae: Vrijenhoekia timoharai sp. nov.; Nereididae: Neanthes adriangloveri sp. nov., Neanthes visicete sp. nov.; Orbiniidae: Orbiniella jamesi sp. nov.), including two belonging to the bone-eating genus Osedax (Siboglinidae: Osedax waadjum sp. nov., Osedax byronbayensis sp. nov.) that are the first to be described from Australian waters. We further provide systematic accounts for 10 taxa within the Ampharetidae, Amphinomidae, Microphthalmidae, Nereididae, Orbiniidae, Phyllodocidae, Protodrilidae, Sphaerodoridae and Phascolosomatidae. Our investigations uncover unique occurrences and for the first time enable the evaluation of biogeographic links between Australian whale falls and others in the western Pacific as well as worldwide.

    Benthic foraminiferal abundances from eastern Baffin Bay, sediment core AMD14-204C (2020)
    PANGAEA
    Details
    Publication Date: 2024-05-31
    Description: Baffin Bay is a semi-enclosed basin connecting the Arctic Ocean and the western North Atlantic, thus making out a significant pathway for heat exchange. Here we reconstruct the alternating advection of relatively warmer and saline Atlantic waters versus the incursion of colder Arctic water masses entering Baffin Bay through the multiple gateways in the Canadian Arctic Archipelago and the Nares Strait during the Holocene. We carried out benthic foraminiferal assemblage analyses, X-ray fluorescence scanning, and radiocarbon dating of a 738 cm long marine sediment core retrieved from eastern Baffin Bay near Upernavik, Greenland (Core AMD14-204C; 987m water depth). Results reveal that eastern Baffin Bay was subjected to several oceanographic changes during the last 9.2 kyrCE1. Waning deglacial conditions with enhanced meltwater influxes and an extensive sea-ice cover prevailed in eastern Baffin Bay from 9.2 to 7.9 ka. A transition towards bottom water amelioration is recorded at 7.9 ka by increased advection of Atlantic water masses, encompassing the Holocene Thermal Maximum. A cold period with growing sea-ice cover at 6.7 ka interrupts the overall warm subsurface water conditions, promoted by a weaker northward flow of Atlantic waters. The onset of the neoglaciation at ca. 2.9 ka is marked by an abrupt transition towards a benthic fauna dominated by agglutinated species, likely in part explained by a reduction of the influx of Atlantic Water, allowing an increased influx of the cold, corrosive Baffin Bay Deep Water originating from the Arctic Ocean to enter Baffin Bay through the Nares Strait. These cold subsurface water conditions persisted throughout the Late Holocene, only interrupted by short-lived warmings superimposed on this cooling trend.

    Description: In laboratory culture experiments, phytoplankton species were exposed to a range of nickel concentrations at GEOMAR Helmholtz Centre for Ocean Research Kiel. The experiments were perfomed between Feburary and August 2021. Overall, three experiments were conducted, each with a different taxonomical species (the dinoflagellate Amphidinium carterae, the coccolithophore Emiliania huxleyi and the diatom Thalassiosira weissflogii). Cells were acclimated to experiment conditions for at least 1 week (under salinity 33, 18˚C, 12:12 light and dark cycle). Throughout the experiment cell density was recorded with BD Accuri C6 Flow Cytometer. After the experiment, nickel concentration was measured with ThermoFisher Scientific ElementXR. The study was supported by the OCEAN-ALK-ALIGN project funded by the Carbon to Sea and the Thistledown Foundation.

    Seawater analysis from cruise KH-14-6 in the western South Pacific Ocean along the GEOTRACES transect GP19 (2023)
    PANGAEA
    Details
    Publication Date: 2024-05-31
    Description: This data contains the basic hydrological parameters, including temperature, salinity, potential density anomaly, potential temperature, dissolved oxygen, silicate, nitrate, phosphate, and chlorophyll-a concentrations, dissolved (d) Cd, dNi, dZn, dCu, dFe and labile particulate (lp) Fe concentrations in the western South Pacific Ocean along the GEOTRACES transect GP19 (~170°W, 64°S - equator). Seawater samples were collected using a clean CTD (Conductivity, Temperature, and Depth) sampling system with Niskin-X bottles during the Japanese GEOTRACES cruise KH-14-6 onboard the research vessel Hakuho Maru from December 2, 2014 to February 26, 2015. Filtered samples for the determination of dissolved trace metals (dMs) were passed through an AcroPak cartridge filter with a 0.8/0.2 µm pore size (Pall Life Sciences) and were transferred to 250-mL low-density polyethylene (LDPE) bottles (Nalgene). Samples for the determination of total dissolvable trace metals (tdMs) were not filtered. The seawater samples were acidified to pH ~2 with ultrapure HCl (Tamapure AA-10, Tama Chemicals) immediately after collection and were stored at room temperature in the laboratory for several years until analysis. An offline automated solid-phase extraction system (SPE-100, Hiranuma Sangyo) equipped with a column of Nobias Chelate-PA1 resin (Hitachi High-Technologies) was used to preconcentrate the trace metals (Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb) in seawater (Minami et al., 2015; doi:10.1016/j.aca.2014.11.016). Unfiltered samples were first passed through a 0.45-µm pore size Millex syringe filter (Merck Millipore) and then introduced into the SPE-100 system. The labile particulate metal (lpMs) concentrations were calculated as the difference between tdMs and dMs. Trace metal concentrations were determined using a high-resolution inductively coupled plasma mass spectrometer (HR-ICP-MS, Element 2, Thermo Fisher Scientific) using the calibration curve method. Temperature was measured using a CTD sensor. Salinity was determined using a bench salinometer that was standardized based on the IAPSO standard seawater, and the oxygen content was measured using the Winkler method. Nutrient concentrations were determined by spectrophotometry using an automated analyzer onboard the vessel. Chlorophyll a (Chl. a) was collected on a 25-mm Whatman GF/F glass fiber filter and measured by fluorometry. Samples were collected using a clean CTD (Conductivity, Temperature, and Depth) sampling system with Niskin-X bottles (Sohrin and Bruland, 2011). Filtered samples for dMs determination were passed through an AcroPak cartridge filter with a 0.8/0.2-µm pore size (Pall Life Sciences) by the pressure of compressed air and were transferred to 250-mL low-density polyethylene (LDPE) bottles (Nalgene). Samples for tdMs determination were not filtered and were transferred from Niskin-X bottles to 250-mL LDPE bottles using a silicon tube. Filtered and unfiltered samples were placed in a cleanroom (Class 100) and acidified with 20% HCl (Tamapure AA-10, Tama Chemicals, Japan) to a pH of 1.9–2.0 within 24 h of sample collection.
