title: 10 daily measurements of water isotopic composition of the surface 2.5 cm of snow from EastGRIP during summer of 2017-2019

description: Water isotopic composition measurements of the surface 2.5cm of snow, with 10 samples retrieved at 10 m increments over a 90m transect. d18O and dD were measured using both Picarro L-2140i and Picarro L-2120-I cavity ring-down isotopologue gas analyzers, while d-excess is calculated using the equation d-excess = dD - 8 * d18O. Samples were collected every ~24h between May and August of 2017 - 2019 at the EastGRIP site in the accumulation zone of the Greenland Ice Sheet. Physical properties, such as SSA and density, were measured in the field, and the samples were subsequently transported to the Alfred Wegener Institute for isotopic analysis.

title: Temperature and salinity in the surface water of the Mackenzie Delta Region during 4 expeditions from spring to fall in 2019

description: During Leg 1, the CTD (CTD RBR Maestro) was manually lowered in the water through an ice hole. During legs 2 to 4, the CTD (CTD RBR Concerto) was installed on a Seabird Scientific optical package frame. Poor quality profiles, that had been affected by ice-covered sensors, were removed. Atmospheric pressure observed at weather stations near the sampling locations (Aklavik, Inuvik, Shingle Point and Tuktoyaktuk) was used to tare the CTD pressure sensors. The salinity was re-measured on discrete water samples (Sal Lab) using Mettler Toledo Conductivity/Salinity/pH meter.

title: Hydrographic and current velocity data (CTD and LADCP) around the Seco de los Olivos seamount during the MEDWAVES (September 2016)

description: The main objectives of the physical oceanography team during the MEDWAVES-ATLAS cruise were to characterize the hydrographic conditions and the structure of oceanic flow to determine the role of the Mediterranean Water in the circulation, over, and around the Seco de los Olivos seamount. To achieve the objectives a set of hydrographic stations were carried out to determinate the hydrographic conditions, the geostrophic circulation and to identify the water masses in the area. In each one of these hydrographic stations, a SBE9 s/n 0851 working at 24 Hz, coupled with a SBE11 (deck Unit) and a SBE32, with 24 bottles of 12 litres, was lowered at less than 55m/min. Besides, a Dual RDI Workhorse 300 khz (slave and master) Lowered Acoustic Doppler Current Profiler was used in each station to measure ocean currents.

title: Stress biomarkers in the cold-water octocoral Dentomuricea aff. meteor during an ex-situ experiment in the Azores

description: We report the results of an aquaria-based experiment testing the effects of suspended particles generated during potential mining activities, on a common habitat-building coral species in the Azores, Dentomuricea aff. meteor. Coral fragments were maintained in 10-L aquaria and exposed to three experimental treatments for a period of four weeks at the DeepSeaLab aquaria facilities (Okeanos-University of the Azores): (1) control conditions (no added sediments); (2) suspended polymetallic sulphide (PMS) particles; (3) suspended quartz particles. Antioxidant stress related biomarkers (glutathione S−transferase, superoxide dismutase, catalase, malondialdehyde) in D. aff. meteor tissues were used to evaluate the degree of cellular stress induced by exposure to PMS and quartz particles at times 0 and 13 days in all treatments and from the control and quartz treatments also at time 27 days of the experiment.

title: Benthic boron isotope data and associated pH determinations, from paper on Cenozoic evolution of deep ocean temperature from clumped isotope thermometry

description: Boron isotope data on benthic foraminifera, spanning 1 to 59 Ma, and used to reconstruct deep ocean pH change over the Cenozoic. Data are from ODP sites spanning water depths of 2500-3600 m in the Equatorial and North Atlantic. Measurements were made on mono-specific samples of the genus Cibicidoides, which were oxidatively cleaned, purified using column chromatography, and analysed using MC-ICPMS. The data are presented as part of a study on deep ocean temperature change over the Cenozoic using clumped isotopes, with the pH estimates used to evaluate the potential pH influence on conventional benthic oxygen isotopes.

title: Digital Elevation Models from the summer season 2019 at the EastGRIP deep drilling site

description: Two-dimensional maps of the snow surface, i.e., digital elevation models (DEMs), were generated from daily sets of photos during the summer season of 2019 at the EastGRIP deep drilling site in the accumulation zone of the Greenland Ice Sheet. From mid-May to the beginning of August 2019, about 170 photos were taken every day along a 40 m long transect using a Sony α 7R camera and a fixed lens of 35 mm focal length. The camera was mounted at a height of ~2 m. The entire covered area is 400 m^2 (= 40 x 10 m). Following a Structure-from-Motion photogrammetry approach described in Zuhr et al. (2021) and using the software Agisoft Metashape, DEMs were generated for each day with suitable weather conditions. The DEMs have a resolution of 1 x 1 cm. Missing areas in the DEMs are either caused by a snow sampling scheme carried out in the same area or by insufficient coverage in the point cloud. The largest gap between consecutive DEMs is three days and happened once. Gaps of two days occurred five times and a one-day gap seven times.

title: Pore water macronutrient data from Greenland margin and the Labrador Sea

description: The dataset contains pore water 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).

title: Operando X-ray scattering during injection to develop an understanding of the limits to recycling in the fabrication of medical products

description: Many medical products are fabricated from semi-crystalline polymers using injection moulding. This work is a key part of project with a consortium of Companies in Marinha Grande  which is focused on increasing the circularity of plastic parts prepared by injection moulding.This proposal is focused on using the operando equipment designed and constructed at CDRSP [1-4] in the past two years which has been upgraded to allow the collection of time-resolved wide-angle X-ray scattering (WAXS) as well as small-angle X-Ray scattering (SAXS). The design is based on the experience gained in the previous beamtime allocations. The central focus of this project is the use of an industrially relevant injection moulding system which can be mounted on the ALBA NCD-SWEET beamline and which enables the time-resolved evaluation of the evolution of the structure and the morphology which accompanies the transformation from the molten state to the solid state of the injected plastic during a single injection moulding cycleto understand the changes induced by including recycled factory waste in the feedstock. The objective is to increase the circularity of the product.

title: Unfolding the effect of Rare Earth element on the nucleation dynamics and morphology of the first REBCO islands with In-situ Grazing-Incidence Small Angle X-Ray Scattering

description: In-situ Grazing Incidence Small Angle X-ray Scattering (GI-SAXS) experiments will be conducted to investigate the morphology and distribution of the initial nuclei during the formation of epitaxial REBCO (RE = Y, Gd, Er) films grown via the Transient Liquid Assisted Growth (TLAG) method. These studies will be performed on Strontium Titanate (STO) model substrates, where precursor films with varying concentrations of RE oxides will be deposited using a chemical solution deposition technique. The nucleation and growth process will be monitored in real time at the NCD-SWEET beamline using an Anton Paar hot stage integrated with a TLAG setup. By precisely controlling the oxygen partial pressure and growth temperature, we will track the formation of the first REBCO islands and their evolution into a continuous layer. GI-SAXS measurements, with acquisition times of up to 40 ms/frame, will provide detailed insights into the nanoscale structure and distribution of the nuclei, while complementary in-situ 2D X-ray diffraction (XRD) data will offer additional information on phase formation. This systematic study of the nucleation mechanisms of Yttrium, Gadolinium, and Erbium-based REBCO films will contribute to a deeper understanding of the TLAG growth process, facilitating improved control over the fabrication of high-quality superconducting thin films.

title: Investigating the field dependence of magnetic return point memory and topology in Pt/Co/Dy ferrimagnetic multilayers

description: Magnetic spin textures exhibit rich physics and hold promise for information technology applications. In rare-earth transition metal ferrimagnets, we observe a persistent magnetic stripe domain pattern with full magnetic return-point memory (RPM), unaffected by out-of-plane (OOP) magnetic fields even after saturation. Notably, these domains retain their OOP contrast regardless of OOP applied field direction but can be fully switched by only a weak in-plane field near 0 mT. In this study, we aim to employ advanced coherent x-ray imaging to investigate the high field dependence of magnetic stripe pattern and their magnetic RPM. In addition, we plan to explore the relationship between emergent skyrmions and faint magnetic stripes by examining their topology and chirality around 50 mT, where skyrmion-like textures appear on top of a weaker magnetic stripe background that seems to act as a guiding pathway for skyrmions. This study will provide insights into magnetic RPM behavior and its potential for ultrafast memory and logic device applications.
