    Dinoflagellate cyst abundances in the benthic nepheloid layer, sediment trap and surface sediments off Figueira da Foz (NW Portugal, Atlantic Iberian margin) (2023)
    PANGAEA
    Details
    Publication Date: 2024-06-17
    Description: This dataset includes counts, percentages and concentrations of all dinoflagellate cyst taxa identified in the benthic nephloid layer (BNL), cyst rain and surface sediments collected along a land-sea transect off Figueira da Foz (NW Portugal, Atlantic Iberian margin) during the Hydrographic Institute (IH)-HABWAVE cruise (16th-19th September 2019). Sampling of the dinoflagellate cyst community in the BNL, the water column (sediment trap) and the surface sediments (together with studies of spatio-temporal changes in physical properties) were carried out in order to investigate the dinoflagellate cyst distribution and the factors (physical and biological) affecting it. Water samples for cyst analyses were collected by a rosette firing system associated with the CTD, and the cyst rain using a sediment trap situated above the BNL. They were filtered (40-47 l) on board through a 150µm-nylon mesh sieve onto a 10µm-calibrated stainless steel sieve (Retsch). In the laboratory, cysts were concentrated by centrifugation. Full and empty cysts were counted to investigate whether a reservoir of viable cysts existed in the BNL. Surface sediments were sampled with a Smith McIntyre grab and using Plexiglass tubes (3.6 cm internal diameter) that were inserted in the sediment to recover the top 1-cm layer. Cysts from sediments were concentrated by density separation with sodium polytungstate (2.016 g/ml).

    Phosphate measurements from the neolithic settlement Wanna 1603, Ldkr. Cux., Germany (2023)
    PANGAEA
    In:  Niedersächsisches Institut für historische Küstenforschung, Wilhelmshaven
    Details
    Publication Date: 2024-06-17
    Description: The samples examined were taken in the run-up to the sondage of a Neolithic settlement site under the bog near Wanna, district Cuxhaven, Germany. In order to determine the extent of the cultural layer, phosphate measurements were taken on the mineral sediment beneath the possible cultural layer. The measurements were carried out in the laboratory using an Agilent Cary 60 UV-Vis. The vanadate-molybdate method (Gericke and Kurmies 1952) was used to prepare the samples. The percentage is calculated according to the specification by = (β)*(measuring solution [4 ml]) / analyte [0.1 ml])*(total volume of digestion solution [1 ml] / conversion factor [1000])*(dilution factor [1])*(conversion factor weighed-in sample [1] /weighed-in sample pre ashed)*100.

    Winter cod 2022: Monitoring data recorded during RV ALKOR cruise AL568b - Gadus morhua body and gonad measurements (2023)
    PANGAEA
    Details
    Publication Date: 2024-06-17
    Description: This data contains monitoring data of the RV ALKOR cruise AL568b conducted in January 2022 (January 24th – February 1st) in the Western Baltic Sea by the University of Hamburg. The cruise was part of the 5-year monitoring programme Winter cod 2021-25 (Monitoring winter spawning activity of Western Baltic cod (Gadus morhua) (2021-25)) of the University of Hamburg aiming at investigating the early-winter spawning activity of Western Baltic cod to identify potential climate-induced shifts in spawning phenology. The data set includes cod single fish analysis data. All single fish measurements were made directly on board. Full wet weights of cod were measured and subsequently cod were gutted and liver weights, gonad weights and sexes, gutted wet weights (i.e., gutted wet mass), gonad stages and liver nematode infestations were recorded, and Otoliths were taken.

    Core incubation macronutrient data from Greenland margin and the Labrador Sea (2023)
    PANGAEA
    Details
    Publication Date: 2024-06-17
    Description: The dataset contains core incubation macronutrient (nitrate+nitrite, nitrite, ammonium, phosphate) concentration measurements, obtained from seven sediment cores collected from the Greenland margin and the Labrador Sea. Porewaters were extracted from the sediment cores using Rhizon samplers and frozen for transport. The frozen samples were thawed according to GoSHIP protocols and analysed for inorganic macronutrients using a SEAL analytical AAIII segmented flow colorimetric auto-analyser. Seawater nutrient reference materials (KANSO Ltd. Japan) were also analysed to check analyser performance and to guarantee the quality control of the final reported data. The typical uncertainty of the analytical results were between 2-3%, and the limits of detection for nitrate and phosphate were 0.02 mmol/m3, and 0.01 mmol/m3 for nitrite. For full methods and analytical quality control, see Hendry et al., 2019. The samples were collected as part of the European Research Council project ICY-LAB (ERC-2015-STG grant agreement number 678371).

    Spatial and temporal abundance and size trends in scyphozoan jellyfish in coastal Icelandic waters in 2008 (2023)
    PANGAEA
    Details
    Publication Date: 2024-06-17
    Description: Scyphozoan jellyfish in Icelandic waters have received limited attention, despite apparent recent increases in jellyfish blooms and considerable regional oceanographic and climatic changes. We studied the species composition, abundance, phenology, and growth of scyphomedusae around the island and explored changes in distribution, species composition, and seasonality by comparing our findings with reports from the 1930s. Scyphomedusae were collected with a Bongo net (60 cm ring diameter, 250 cm net length, and 500 µm mesh size) in the top 10 m of the water column in five regions (fjords between 64 and 66°N) around Iceland in the spring, summer, and autumn of 2008. Between 4 and 36 tows were performed per sampling region. This dataset includes umbrella diameter, dry and wet mass, as well as abundance data of two species: Aurelia aurita and Cyanea capillata.
