    Benthosema glaciale diet across the North Atlantic (2022)
    PANGAEA
    Details
    Publication Date: 2023-09-02
    Description: The data submitted is used in a comparative analysis of the diet of one of the globally most numerous myctophids, the Glacier lantern fish Benthosema glaciale, across four deep basins of the North-Atlantic. B. glaciale is a small fish species that contribute to carbon flux to the deep basins of the open ocean, and is thus considered an important element of the biological carbon pump (BCP). Data submitted is length and weight of fish analyzed for stomach content. In addition there are available taxonomic information, weight and number of prey items of each fish that has stomach content, as long as it has been possible to assign prey to a species or other taxonomic category. Unidentified prey usually had a high degree of digestion and individual items could not be counted, but could be weighed. Sampling were undertaken onboard the RV G.O. Sars during a six week long transatlantic scientific survey from Bergen (Norway) to Nuuk (Greenland) and back to Bergen in May and June 2013. Samples of B. glaciale for stomach content analysis were collected from three Harstad trawl hauls and 16 Macroplankton trawl hauls. The Harstad trawl is a graded (variable mesh size), small mid-water trawl with 20 m vertical opening and 15 m wing spread (Godø et al., 1993). The Macroplankton trawl on the other hand is a light pelagic trawl that has a nominal 6x6 m trawl opening and mesh size of 3 mm square light opening (8 mm stretched, knot to knot) from the trawl mouth along the entire trawl length to the cod-end (Hassel et al., 2017; Klevjer et al., 2020).

    Macroplankton and micronekton trawl data from the Norwegian Sea 2019-2020 (2024)
    PANGAEA
    Details
    Publication Date: 2024-02-15
    Description: We provide here a curated set of data containing standardized catch biomasses and abundances of key macroplankton and mesopelagic fish taxonomically identified to species or genera or the nearest possible taxonomic group collected by a Macroplankton trawl (~6 m x 6 m mouth opening, non-graded mesh with 3 mm light-opening) from cruises in the Norwegian Sea during the International Ecosystem Survey in the Nordic Seas (IESNS) in May to June 2019 and 2020. The collected material is obtained from standardized V-shaped hauls down to a maximum depth of about 1000 m, although some shallower V-hauls are included either to look at the vertically migrating mesopelagic organisms that enter the epipelagic domain during nighttime hours, or because of depth restrictions due to shallow bottom topography. This dataset holds the biomass and abundance data of species or taxonomically identified categories. Filtered water volume (m³) was determined by calculating the towed horizontal distance (m) from when the trawl was deployed until maximum depth (m) and similarly when retrieved. Then, knowing the maximum depth of the trawl, by trigonometric calculations the trawl path (hypothenuse) during downcast and upcast were derived. The filtered volume was calculated by multiplying the summed towpath distance (m) by the nominal trawl opening of 36 m².

    Integrated daytime EK60 echosounder data from Malaspina-2010 cruise (2020)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: Daytime acoustic data (nautical area scattering coefficients, in m2/nmi2) integrated over 2 m vertical bins, from 200 to 1000 m depth. Data in each “pixel” is the average of all cleaned and valid data recorded at that depth range, in a time period starting 8 hours before the start of a station (defined as start of the CTD cast) and ending 8 hours after the start of the station, subject to being in the period between 1 hour after local sunrise and 1 hour prior to local sunset (i.e. during local daytime hours, but removing crepuscular periods). The relatively long interval over which data was accepted around each station was chosen due to frequent occurrences of periods of unusable acoustic data. Note that the provided positions correspond to the fixed Malapina station at that date, not the start and end point of the data collection.

    Description: These data consist of raw echosounder observations collected during the Malaspina 2010 Spanish Circumnavigation Expedition (14th December 2010, Cádiz-14th July 2011, Cartagena). The cruise was divided into seven legs: leg 1 (14th December 2010, Cádiz-13th January 2011, Rio de Janeiro), leg 2 (17th January 2011, Rio de Janeiro-6th February 2011, Cape Town), leg 3 (11th February 2011, Cape Town-13th March 2011, Perth), leg 4 (17th March 2011, Perth-30th March 2011, Sydney), leg 5 (16th April 2011, Auckland-8th May 2011, Honolulu), leg 6 (13th May 2011, Honolulu-10th June 2011, Cartagena de Indias) and leg 7 (19th June 2011, Cartagena de Indias-14th July 2011, Cartagena). Echosounder observations were made from the BIO Hespérides (A-33) using two EK60 GPTs operating two hull-mounted transducers (38 and 120 kHz). A calibration was carried out prior to the start of the expedition (30th of November 2010, close to Mazarron port, water temperature c. 17 degrees C) and values of the peak transducer gain and Simrad correction factor for both frequencies were updated in the ER60 software. Data are stored in raw proprietary Simrad (Bergen, Norway) format (.raw, .idx, .bot files).

    Description: This file provides daily/per station summaries of daytime and nighttime acoustic data (omitting data recorded within 1 hour of sunrise and sunset), specifically per day and night mesopelagic average nautical area scattering coefficient (NASC 200-1000 m), average total NASC (0-1000 m), and weighted mean depths (WMD) of mesopelagic and total NASC. Migration amplitude is the difference in day and night WMD, day to night ratio is the ratio of daytime to nighttime total NASC (0-1000 m) and migration ratio is calculated from the relative drop in mesopelagic backscatter (NASC 200-1000 m) during night. For details of calculations see Klevjer et al. 2016. Note that the provided positions correspond to the fixed Malapina station at that date, not the start and end point of the data collection.
