    Conductivity, temperature, and depth measurements at the RMS Titanic wreck and Nargeolet-Fanning Ridge, Northwest Atlantic, in summer 2022 (2023)
    PANGAEA
    Details
    Publication Date: 2024-03-11
    Description: To gain information on the physical parameters of deep water in the Northwest Atlantic, CTD measurements were taken during seven dives to the RMS Titanic wreck (front of bow approx. 41.7330181, -49.9460561; 3816 m water depth) and one dive to the Nargeolet-Fanning Ridge (approx. 41.5980514, -49.4386889; 2896 m water depth) during the OceanGate expedition aboard the AHTS Horizon Arctic, 15 June - 25 July 2022. The CTD measurements of the water column down to a maximum water depth of 3853 m were conducted using a Valeport MIDAS SVX2 6000 unit attached to the submersible Titan for the duration of each dive and provided standard data for conductivity, temperature, and pressure. Conductivity and temperature data were used to compute salinity.

    Description: Analyzing historic cruise data for microplastics is an effective way to create baseline level understanding of microplastic pollution through time. This study analyzed 112 benthic specimens gut contents for ingestion of microplastics. These specimens were collected as part of a research cruise on the RRS Discovery D340b from 26 June to 4 July 2009 as part of the Oceans 2025 programme, the cruise Chief Scientist being Mark Inall. Out of the 112 specimens dissected, only 9 contained microplastic samples. These samples were photographed and their microplastic signatures were analysed using Raman Spectroscopy.

    Description: The data provided here were derived using a new ArcGIS-based British Geological Survey (BGS) seabed mapping toolbox that semi-automatically delineated over 500 Lophelia reef 'minimounds' from bathymetry data of the Mingulay Reef Complex. The morphometric and acoustic characteristics of the minimounds were also automatically quantified and captured using this toolbox. Coral presence data were derived from high-definition remotely operated vehicle (ROV) records and high-resolution microbathymetry collected by a ROVmounted multibeam echosounder. With a resolution of 0.35 9 0.35 m, the microbathymetry covers 0.6 km2 in the centre of the study area and allowed identification of individual live coral colonies in acoustic data for the first time. Maximum water depth, maximum rugosity, mean rugosity, bathymetric positioning index and maximum current speed were identified as the environmental variables that contributed most to the prediction of live coral presence. These variables were used to create a predictive map of the likelihood of presence of live cold-water coral colonies in the area of the Mingulay Reef Complex covered by the 2-m resolution data set.

    PANGAEA
    Details
    Publication Date: 2024-03-11
    Description: To gain information on the chemical parameters of deep water in the Northwest Atlantic, water samples were taken using a Niskin bottle deployed at five stations at the RMS Titanic wreck site (stations: 0075, 0079, 0080, 0081, 0082 - deepest samples at station 0081: 41.7335576, -49.9467401, 3831 m water depth) and at one station at the Nargeolet-Fanning Ridge (station 0083: 41.5975604, -49.439188, 2870 m water depth) during the OceanGate expedition aboard AHTS Horizon Arctic, 15 June - 25 July 2022. A total of 20 water subsamples were collected and analysed for total alkalinity (TA) and dissolved inorganic carbon (DIC). TA was analysed using an Apollo SciTech AS-ALK2 alkalinity titrator and DIC was analysed using an Apollo SciTech AS-C3 inorganic carbon analyser. The aragonite saturation state was calculated using the CO2SYS system (Lewis and Wallace, 1998).

    Water parameters from a long-term multiple stressor aquarium experiment with the cold-water coral Desmophyllum pertusum (2024)
    PANGAEA
    Details
    Publication Date: 2024-04-09
    Description: We conducted a long-term (6 months) multiple stressor aquarium experiment with the cold-water coral Desmophyllum pertusum (syn. Lophelia pertusa) under future environmental conditions. The experiment with live corals consisted of four different treatments to investigate the combined effect of ocean acidification, warming, deoxygenation and food limitation on their physiology: 1) control (9 °C, pH 8.1, 100 % oxygen, 100 % food availability), 2) multiple stressor with high feeding (12 °C, pH 7.7, 90 % oxygen, 100 % food availability), 3) multiple stressor with low feeding (12 °C, pH 7.7, 90 % oxygen, 50 % food availability) and 4) reduced oxygen (9 °C, pH 8.1, 90 % oxygen, 100 % food availability). Every treatment consisted of three replicate tanks with four live corals (treatments 1-4). In a parallel experiment, we also examined the dissolution rates of dead coral skeletons at three different pCO2 levels (treatment 5: 750, treatment 6: 1000 and treatment 7: 1250 ppm) after 1.5, 3, 4.5 and 6 months. Every treatment consisted of three replicate tanks with two dead coral skeletons (treatments 1, 2 and 5-7). Water parameters (temperature, salinity, pH and oxygen concentration) were measured five times per week in every coral tank.

Every treatment consisted of three replicate tanks with four live corals (treatments 1-4). The physiological parameters were determined after 1.5, 3, 4.5 and 6 months of the experiment. Growth rates were measured using the buoyant weighing technique (Jokiel et al. 1978) and respiration rates were conducted using closed-cell incubations.
