title: Physical oceanography during the cruise SO269 in South China Sea in August 2019, station SO269_119-1 (SCS84)

description: This dataset provides 131 CTD profiles measured on board of the German R/V Sonne (cruise SO269) in the northern South China Sea, under the project SOCLIS – South China Sea Natural Laboratory under Climatic and Anthropogenic Stress, in August and September 2019. The 131 profiles of temperature, salinity, dissolved oxygen, fluorescence, turbidity, surface irradiance (SPAR) and Photosynthetically active radiation (PAR), and sound velocity were measured using a CTD Sea-Bird SBE 911 plus, together with oxygen sensor (SBE 43), PAR sensor (Biospherical, QCP-2350 + QSR-2200), and a fluorometer (WET Labs ECO-FLNTU(RT)D). Additionally, oxygen saturation, potential temperature and sigma-theta (with reference to the surface) were calculated. The 131 CTD profiles are distributed by 81 stations and aim to study the impact of a growing anthropogenic pressure around the Pearl River Estuary into the northern shelf of the South China Sea towards the deep sea. The dataset was used to study the presence and spatial distribution of natural and synthetic estrogenic compounds and pharmaceutical and personal care products (PPCPs) in the Pearl River Estuary and northern shelf of the South China Sea.

title: 3D seismic, multibeam and sonar interferometry scanning bathymetry data of Espirito Santo and Campos Basins - SW Atlantic Ocean

description: Digital Bathymetric Model (DBM) with cell size of 93 m, created through a process of merging two original DBMs: Espírito Santo Basin DBM and Campos Basin DBM. Sectors, where the original DBMs overlapped, were excluded, as well as cells with missing data (NA) and those with depth values greater than zero. The fusion of the two DBMs were performed through image blending and subsequent processing with a low-pass filter. Bathymetric data originated from 3D seismic, multibeam and sonar interferometry scanning bathymetry data produced by Brazilian Petroleum Corporation — Petrobras in Campos and Espírito Santo basins in the context of environmental studies required during various oil and gas production and drilling licensing processes. Complementary data derived from log sheets produced by the Directorate of Hydrography and Navigation – DHN (Brazilian Navy), ETOPO data obtained from the NGCD (National Geophysical Data Center) of NOAA (National Oceanic and Atmospheric Administration), SRTM (Shuttle Radar Topography Mission). Petrobras environmental data analyses (meteoceanography, geology and geomorphology, chemistry of water and sediment, and biota) are conducted by Petrobras Research and Development Center (CENPES).

title: Ash-Free-Dry-Mass and oxygen consumption of the juvenile cold-water coral Caryophyllia (Caryophyllia) huinayensis exposed to increased sediment load

description: The table shows respiration data, dry mass, and ash-free dry mass (AFDM) of juvenile Caryophyllia (Caryophyllia) huinayensis individuals exposed to a natural, a 100-, and 1000-times increased sediment concentration. Corals after a 12-week exposure experiment towards the three sediment concentrations ("long-term") and corals exposed to the natural and highest concentration only for the respiration experiment ("short-term"), were studied for respiration for 24 hours. Mean oxygen consumption rate of C. huinayensis was determined by closed-chamber respirometry. The values have been corrected for the volume of the incubation vessels, the background respiration and the AFDM of the animals and calculated to mg O2/AFDM/day.
description: Sample ID: The ID is composed of the sediment concentration (C = natural concentration, T1 = 100-fold and T2 = 1000-fold the natural concentration), the exposure of the animals (newly exposed: ST; from the long-term experiment: no designation), the orientation of the coral (H: horizontal, V: vertical) and the numbering of the animals (1-5).Individual code: The individual code indicates the labelling of the corals. The first letter denotes the colour of the opalite plates used to mark the screws on which the animals were attached, the second digit indicates the number of the plate and the last letter indicates the orientation of the coral with h (horizontal) or s (vertical).This dataset was generated within the framework of the co-operation between the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (programme: 'Changing Earth – Sustaining our Future', Topic 4.2), the Huinay Scientific Field Station, European Union's Horizon 2020 iAtlantic project (Grant Agreement No. 818123) and the Centre for Marine Environmental Sciences of the University of Bremen.

title: Turbidity during a laboratory experiment on effects of sediment load on juvenile individuals of the cold-water coral Caryophyllia (Caryophyllia) huinayensis

description: Treatment water contained a natural, 100- or 1000-fold increased sediment concentration in the experimental vessels (340 ml glass beakers) of the corals C. huinayensis, to which they were exposed during the periods between water changes (2-3 d). Using a turbidimeter (2100Qis, Hach Lange GmbH, Düsseldorf, Germany), the turbidity of the treatment water was measured every day and twice a day when a water change took place (just before and after the water change). The mean values from the bulk samples (ten vessels per concentration; bulk sample of water from five vessels of one concentration = one sample; per concentration = two samples) were calculated and are shown in the table, as well as the standard deviation.

title: Effects of sediment load on buoyant mass and calcification of juvenile individuals of the cold-water coral Caryophyllia (Caryophyllia) huinayensis

description: The mass of horizontal and vertical downwards oriented juvenile Caryophyllia (Caryophyllia) huinayensis was determined during a 12-week sediment experiment. Corals were exposed to a natural (0.0042 ml/l), a 100-fold and a 1000-fold sediment concentration. The mass of the individual corals was measured at the beginning (week 0), in the middle (week 6) and at the end (week 12) of the experiment. The mass of the individuals was determined using the buoyant weight method (Davies, 1989) and by calculating the skeletal mass in air after Jokiel et al. (1978). From this, the increase in mg per day and year for the individuals were determined.

title: Spectrograms of singing humpback whales migrating through Bermuda

description: The dataset consists of 14 spectrograms of humpback whale (Megaptera novaeangliae) vocalisations. These were created from 29-minute-long recordings off Bermuda using three separate deployments of Autonomous Multichannel Acoustic Recorders G3. Two hydrophones were deployed on Challenger Bank, from 31 March to 6 September 2018 and from 10 September 2018 to 23 April 2019. The third hydrophone was deployed at Sally Tuckers on the Bermuda Platform from 31 March to 10 September 2018. Vocalisations were visualised and analysed as spectrograms (fast Fourier transformation size: 2048 points, 75% overlap, sample rate = 16000 Hz, Hann window, frequency resolution: 7.8 Hz, time resolution: 32 ms), produced using Raven Pro 1.6 sound analysis software. Six of the 14 spectrograms in the dataset illustrate the first and last times that humpback whales were acoustically detected during each deployment. The four spectrograms from Challenger Bank are from the first deployment date (31 March 2018), 18 May 2018, 26 December 2018 and the recovery date 23 April 2019. The spectrograms from Sally Tuckers are from the deployment date (31 March 2018) and 19 May 2018. A seventh spectrogram illustrates an anomalous occurrence of a humpback whale vocalisation outside the normal singing season, recorded on Challenger Bank on 31 August 2018. The remaining seven spectrograms illustrate the humpback whale song structure encountered in spring 2018 on Challenger Bank. These were recorded on 6, 13, 20 and 27 April 2018, and on 3, 11 and 18 May 2018. The dataset allows users to acoustically verify the presence of humpback whales in Bermuda's waters from late December to mid-May, but also to characterise and compare humpback whale song structure over time or elsewhere.
