title: Mapping the frost susceptibility of the ground from thaw-season InSAR surface displacements and extrapolated active layer thicknesses, Ilulissat, West-Greenland

description: Interferometric Synthetic Aperture Radar (InSAR) images (L1 Single Look Complex data from ESA/Copernicus Sentinel-1) were acquired between May and September during the thawing seasons from 2015 to 2019, over the area of Ilulissat, West Greenland. Rasters of thaw-season ground surface displacements were obtained from the interferometric processing of the SAR scenes. The 2015-2019 average seasonal displacement (S) and long-term deformation rate (R) were derived by least-squares inversion from the surface displacement rasters. In addition, active layer thicknesses (ALT) probed in Ilulissat at the end of the summers of 2020 and 2021 were extrapolated using a vegetation map derived from a Random Forest classification of multi-temporal Sentinel-2 optical images. The average seasonal displacement and extrapolated ALT were finally used to estimate the amount of ice present in the active layer, indicating the frost susceptibility of the ground.This dataset first contains the yearly thaw-season surface displacement rasters in the radar line-of-sight (LOS) direction, and the derived average seasonal and long-term deformation rasters. Secondly, the ALT measurements and floristic data used as inputs and validation in the study are provided along with the land cover classification, extrapolated ALT and frost susceptibility index rasters.

title: Physical oceanography (CTD) data in the vicinity of Herschel Island - Qikiqtaruk, Yukon, Canada (2015-2023)

description: This dataset contains CTD measurements taken in 2015, 2016, 2017, 2018, 2019, 2022, and 2023 during expeditions to Herschel Island - Qikiqtaruk, Yukon, Canada. For the data recording a CTD CastAway was used. The sampling was conducted from a boat from which the CTD was lowered to the sea floor at the specific sampling sites. The sampling information encompasses the GPS position, water depth, pressure, temperature, electrical conductivity, specific conductance, and salinity.

title: KOSMOS 2018 Gran Canaria mesocosm study on artificial upwelling: 14C primary production

description: Size fractionated primary productivity rate measurements through 14C radioisotope incorporation rates from a KOSMOS mesocosm experiment carried out in the frame work of the Ocean Artificial Upwelling project. The experiment was performed in the North-East Atlantic Ocean off the coast of Gran Canaria in autumn 2018 and lasted for 39 days. In this study we investigated the effect of different intensities of artificial upwelling combined with two upwelling modes (recurring additions versus one singular addition) on the phytoplankton community. Data shown includes production rates of dissolved organic carbon, particulate organic carbon in 3 size fractions (0.2-2 µm, 2-20 µm, &gt;20 µm) and total organic carbon.

description: 1-m vertical resolution snow profile isotope data (dD, d18O, dxs, dxsln) from EastGRIP, Greenland. An age-depth model has been applied based on when peak (max/min) monthly mean temperatures occur. The results of this modeled snow age are called Age-depth in this data set. In the absence of constraining peak monthly mean temperatures, a mean accumulation rate for the relevant time period was used for the age-depth model.

title: KOSMOS 2020 Peru mesocosm study on ecosystem responses to different light and upwelling intensities: carbon and nitrogen uptake rates from water samples

description: This data is part of the BMBF project CUSCO (Coastal Upwelling Systems in a Changing Ocean). Here we report carbon and nitrogen uptake rates by phytoplankton collected during a 35-day experiment where we enclosed natural plankton communities in in-situ mesocosms off Peru. The experiment investigated the interactive effects of light and upwelling on the Humboldt upwelling ecosystem by mimicking a gradient of upwelling intensities (0%, 15%, 30%, 45% and 60%) under summer-time high light and winter-time low light. Integrated seawater samples from a depth between 0 and 10m were collected using a 5L Integrating Water sampler (IWS; Hydro-Bios, Kiel). Samples were spiked with 13C labelled sodium bicarbonate and 15N labelled potassium nitrate. Samples were incubated for 24 hours at light intensities that resemble the light conditions in the mesocosms. After incubation a subsample (150-1000 ml) was filtered onto a 0.7 µm pre-combusted glass-fiber filters (GFF, Whatmann). The filters were acidified, then dried in the oven at 60 °C and later measured using an elemental analyzer (Flash IRMS, ThermoFisher) connected to a mass spectrometer (Delta V Advantage Isotope Ratio MS, ThermoFisher) with the ConFlo IV (ThermoFisher). Carbon and nitrogen uptake rates were calculated based on Slawyk et al. (1977, DOI:10.4319/lo.1977.22.5.0925) and Shiozaki et al. (2009, DOI:10.3354/meps07837) respectively.

description: Mesozooplankton (mesoZP) per capita mass, elemental composition and stable N isotopes during the mesocosm experiment in the Canary Islands in autumn 2019. Depth-integrated (0-2.5m) water samples were taken over the course of 33 days. Metazoan zooplankton were split into three size fractions (55-200, 200-500 and &gt;500 µm), picked into tin cups in groups and C, N and δ15N measured in an element analyser coupled to a mass spectrometer. Particulate organic matter (&gt;0.7µm) was also measured for a comparison of C/N between the bottom of the food web and mesoZP grazers. The upwelling treatment started on day 6.

title: Collecting information of the genus Exsuperantia Özdikmen, 2009 (Tetractinellida: Phymaraphiniidae) with description of a new species from the Atlantic Ocean

description: Phymaraphiniidae Schrammen 1924 (Porifera: Astrophorina) is a family of lithistid demosponges that has received little attention in the past decades. The systematic problems within this family have not been addressed for a long time due to the absence of new records and material. The genus Exsuperantia Özdikmen 2009 was first described by Schmidt (1879) as Rimella to allocate the species Rimella clava, found in the Caribbean. In 1892, Topsent found what he thought to be the same species described by Schmidt in the Azores, and synonymized it with Racodiscula clava, as he thought this species belonged to the family Theonellidae Lendenfeld 1903. However, Rimella and Racodiscula belong to distinct families: Rimella to Phymaraphiniidae, and Racodiscula to Theonellidae. Due to the fact that the genus Rimella was already preoccupied by a gastropod, it was renamed as Exsuperantia. In result of the poor preservation of Schmidt's material and the absence of new specimens, the attribution of Topsent's specimens to the family level remained obscure. Here, we review the genus Exsuperantia based on the analysis of new material recently collected during various research expeditions in the northeast Atlantic Ocean. The comparison of these new specimens with Schmidt's and Topsent's type material, allowed us to assign Topsent's specimens to a new species, Exsuperantia archipelagus sp. nov., and confirm its attribution to the family Phymaraphiniidae (not Theonellidae). Phylogenetic reconstructions using newly generated sequences of the cytochrome subunit (COI) marker also support the assignment of the new species to the family Phymaraphiniidae (not Theonellidae).

title: Collecting information and identification of New England Seamount Geodia species

description: We report the first records of the sponge genus Geodia (Demospongiae, Tetractinellida, Geodiidae) from the New England Seamounts and Muir Seamount, at lower bathyal depths. Nine specimens collected between 2000 and 2005 belong to two boreal species (Geodia macandrewii and Geodia barretti) and a temperate species (Geodia megastrella). These records extend the distributions of these deep-sea amphi-Atlantic species to the west. Most of these specimens were originally fixed in formalin, which substantially degraded the DNA. We nonetheless managed to sequence two cytochrome c oxidase subunit I (COI) mini-barcodes: the universal mini-barcode at the 5' end of the Folmer barcode (130 bp) and a newly proposed mini-barcode at the 3' end of the Folmer barcode (296 bp). These mini-barcodes unambiguously confirmed our identifications. As an additional test, we also successfully sequenced these two mini-barcodes from the holotype of G. barretti, collected in 1855. We conclude by advocating the use of mini-barcodes on formalin-fixed or old specimens with degraded DNA.
