title: Phagocytosis assay on the breadcrumb sponge Halichondria panicea using microalgae, bacteria and latex beads: FACS quantification

description: Individuals of the breadcrumb sponge Halichondria panicea were collected from the field to perform phagocytic experiments. Collection site: coast of Schilksee (54.424278 N, 10.175794 E; Kiel, Germany) on August 7th 2022 at 8 am. Sponges were collected by carefully detaching them from crevices at 1-3 m depth by snorkeling. Name of the laboratory: H. panicea individuals were transported to the KIMMOCC climate chamber facilities at GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany), where they were kept for two weeks under controlled temperature (room: 10°C; water: 17°C), and with water supplied from the Kiel Fjord. Culture conditions during the experiment: The phagocytic experiments started on Aug 15th 2022, and were performed in the aforementioned facilities of GEOMAR. All the experiments lasted for one week. The experiments consisted on incubating whole sponge individuals in natural seawater for 30 min with green microalgae (Nannochloropsis sp.; live culture purchased from BlueBio Tech (Germany)), live TAMRA-stained bacteria (isolate PP-XX7 ; 16S rRNA gene sequence similarity of 98.6 % with Vibrio sp. NBRC 101805 and 97.0% to Vibrio variabilis R-40492T),) or 1 µm fluorescent latex beads (Fluoresbrite YG microsphere, Cat. 17154-10, Polyscience). Water samples were taken at time intervals through the incubation period to estimate particle uptake (i.e., filtration) by the sponge using flow cytometry. Fluorescence-activated cell sorting (FACS) of sponge cells extracted from H. panciea tissue from the individuals used during the phagocytic experiment was used to quantify phagocytic activity (i.e., the population of sponge cells with internalized particles).FACS quantification of phagocytic sponge cells of H. panicea individuals used during the phagocytic assays. Sponges were incubated for 30 min with three Nannochloropsis sp., TAMRA-stained bacteria (Vibrio sp.), or fluorescent latex beads (1 µm). Differenet algal concentration and chase periods were tested. The sponge (host) cell suspension from each individual was run in the FACS three times (i.e., 3 technical replicates). The average number of events of the replicates is presented. Controls: individuals incubated without particle to correct for natural fluorescence in sponge cells. Bulk sponge cells: total DAPI-stained cell fraction; Non-phagocytic cells: cells without incorporated particle; Phagocytic cells: cells with incorporated particle.

title: Dissolved inorganic carbon and total alkalinity of seawater samples from the Weddell Sea for RV POLARSTERN expedition PS117

description: Discrete seawater samples for the determination of dissolved inorganic carbon (DIC) and total alkalinity (TA) were collected from CTD stations during RV POLARSTERN expedition PS117, between 15 December 2018 and 7 February 2019. Seawater samples were collected from stations that used the AWI-operated CTD, as well as the Ultra-Clean-CTD, operated by NIOZ. DIC and TA were measured using coulometric titration and potentiometric titration, respectively, on a VINDTA 3C system. Nutrients were measured with UV-Vis spectrophotometry and a continuous gas-segmented flow auto-analyser. Data for station 41 have previously been published on Pangaea and are excluded from this dataset (https://doi.org/10.1594/PANGAEA.946363). Bottle data (including nutrients) from the AWI CTD and Ultra-Clean-CTD stations have already been published and are stored on Pangaea under https://doi.org/10.1594/PANGAEA.910673 and https://doi.org/10.1594/PANGAEA.940209, respectively. Data quality flags follow the WOCE quality code definitions for water sample measurements. Details on sample collection and analysis methods for DIC and TA can be found in Droste et al. (2022).

title: Heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy DS2018a: 30 s after the heating cycle

description: Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA DS2018a is an autonomous instrument that was installed on landfast ice in Prydz Bay, East Antarctica, in May 2018. The buoy was deployed at 68.57°S; 77.95°E, ~1 km northwest off Australian Station Davis Coast with initial thicknesses of snow and ice of 0.06 and 0.80 m, respectively, on 28 May 2018. The thermistor chain was 5 m long and included 240 sensors with a regular spacing of 2cm. The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function of depth and time between 28 May and 10 November 2018 in sample intervals of 6 hours for temperature and 24 hours for temperature differences.
description: The data set has been processed as follows: obvious inconsistencies (missing values) and and unrealistic values have been removed.

title: Code from: PID-controller enhanced artificial β-cells

description: Conventional management of diabetes via injection or external insulin
 pumps suffers from inconvenience and inability to accurately maintain
 blood glucose levels. A potential solution to these problems consists of
 implanting synthetic artificial β-cells that can sense glucose and
 transcribe insulin protein. Experimental results from Xie et al. show
 these cells are able to release insulin and somewhat improve postprandial
 glucose levels in diabetic mice. However, they fail to achieve the degree
 of glucose regulation as in healthy mice. In our analysis, we explain that
 this artificial β-cell system has a major disadvantage: it is a
 high-dimensional dynamic system but with little tuning space. Here, we
 propose an analytical model of a PID-controller-based enhanced artificial
 β-cell design to solve this issue. Our numerical simulations show that a
 model of PID-controlled engineered artificial β-cells can shut down
 production of insulin in time and maintain a proper glycemia level, in
 addition to adding more tuning space. These enhanced models of
 PID-controller-based artificial β-cell are thus able to perform better in
 regulating glucose levels in Type 1 diabetic mice compared with artificial
 β-cells without PID-control.

title: Calcareous nannofossil data from IODP Site 371-U1509

description: The onset of the first sustained Antarctic glaciation at the Eocene-Oligocene Transition (~34 Ma; EOT) was marked by several changes in calcareous nannofossils coinciding with long-term cooling and modifications in the sea-surface water structure. Here, we combined a high-resolution calcareous nannofossil assemblage data (%) with bulk geochemical data from IODP Site U1509 (New Caledonia Trough, Tasman Sea) in order to give an overview of the paleoclimatic and palaeoceanographic evolution of the study area.

title: Application of photographic ‘capture-recapture’ modelling to estimate recruitment and apparent survival in a long-lived territorial raptor

description: Survival is a life history trait that contributes most to population
 dynamics in long-lived birds, and the study of individual characteristics
 is relevant for population conservation. Here we provide information on
 territorial recruitment and individual replacement in a population of
 Bonelli’s eagle Aquila fasciata in southeastern Spain based on a long-term
 photographic capture-recapture 19-year dataset. We also investigated how
 individual factors such as sex, age, experience and age at first breeding
 influence the apparent survival of breeding Bonelli’s eagles using
 Cormack–Jolly–Seber models. An increase in recruitment rates and a
 decrease in age at first breeding were observed in the breeding population
 over time. The apparent survival was high, and the reproductive dispersal
 was very low. The improvement in apparent survival was age-related and
 higher in females (0.90 for non-adults and 0.92 for adults) than in males
 (0.87 for non-adults and 0.89 for adults). These findings can be explained
 by age-related improvements and differences in movement behaviour between
 sexes during the breeding season, with females being exposed to lower
 risks from anthropogenic or natural causes. We also found a positive
 relationship between territorial experience and the probability of
 apparent survival, with inexperienced female breeding birds having a
 higher survival than males. Our results showed that immature breeders had
 a similar survival to experienced or older birds breeding for the first
 time, suggesting that age at first reproduction is controlled by
 reproductive restraint. Our results provide demographic information that
 improves the understanding of the population dynamics of the long-lived
 territorial species, and their estimation has important implications for
 the management and conservation of Bonelli’s eagle populations.

title: Drill hole measurements of fast ice and sub-ice platelet layer thickness, and snow depth in McMurdo Sound - November 2018

description: Here, we present drill hole measurements carried out at 14 field sites distributed over a ~1500 km^2 area of fast ice in the south of McMurdo Sound, Antarctica between 1 and 19 November 2018. At each site, five holes were drilled in the fast ice at the centre and end points of two cross‐profile lines, each 30 metre long. Sea ice and SIPL thicknesses were measured with a suspended thickness probe and metal bar using the procedure described in Price et al. (2014). Snow depth measurements at centimetre accuracy were made at half‐metre intervals along the cross‐profiles using a metal ruler or a GPS‐equipped Magnaprobe. Sea ice freeboard (i.e., the height of the sea ice surface above sea level) was measured in each of the drill holes. The average value for each parameter was calculated at each field site to provide a representative measurement over the 30 metre cross-profile fast ice area. The drill hole measurements were used to underpin spatial distribution surveys of the aforementioned parameters, to inform electromagnetic induction forward and inverse models, and to ground-validate satellite altimetry assessments of fast ice freeboard and derived ice thickness in McMurdo Sound.

title: A global compilation of diatom silica oxygen isotope records from lake sediment: additional information on the lakes and sites corresponding to the records

description: Oxygen isotopes in biogenic silica (δ18O BSi) from lake sediments allow for quantitative reconstruction of past hydroclimate and proxy–model comparison in terrestrial environments. The signals of individual records have been attributed to different factors, such as air temperature (T air ), atmospheric circulation patterns, hydrological changes and lake evaporation. Here, we provide 55 composite down–core records published to date and complemented with additional lake basin parameters (e.g. lake water residence time and catchment size) to best characterize the signal properties. Records feature widely different temporal coverage and resolution ranging from decadal–scale records covering the last 150 years to records with multi–millennial scale resolution spanning glacial–interglacial cycles. Best coverage in number of records (N=37) and datapoints (N=2112) is available for northern hemispheric (NH) extra–tropic regions throughout the Holocene (corresponding to Marine Isotope Stage 1; MIS 1).

title: Microstructure mapping, Raman, Visual Stratigraphy and SEM measurements of the EGRIP and EDML ice core

description: Insoluble and soluble impurities, enclosed in polar ice sheets, have a major impact on the deformation behaviour of the ice. Large-, Macro and Micro-scale deformation observed in ice cores has been retraced to impurities in the ice, and therefore the exact location of the impurities is important. Over the years different techniques have been developed to analyse the location, and chemistry, of impurities and the following figures are examples of general methodological concepts.1_cloudy_bands_details.jpg displays a sample from a depth of 1917 m from the East Greenland Ice Core Project (EGRIP) deep ice core, NE-Greenland; the drilling has started in 2016 and is still on-going. A) shows a Visual Stratigraphy image, which was taken in June 2019 by Nicolas Stoll at the EGRIP drill site. It shows cloudy bands and the stratigraphy of the ice sample, covering a few years of age, and is used to count annual layers, and to derive information about the deformation of ice. B) and C) are microstructure maps of the same sample, created by Nicolas Stoll in July 2020 at the Alfred Wegener Institute, Bremerhaven following the technique described by Kipfstuhl et al. (2006). These show grain sizes- and shapes, grain boundaries and sub-grain boundaries in detail to derive information about the deformation of ice.4_microstructure.jpg are microstructure maps of an EGRIP ice core sample from a depth of 757.4 m, created by Nicolas Stoll in July 2020 at the Alfred Wegener Institute, Bremerhaven following the technique described by Kipfstuhl et al. (2006). These show grain sizes- and shapes, grain boundaries, sub-grain boundaries, and micro-inclusions in detail to derive information about the location of inclusion in ice.5_SEM_EDML.jpg are Scanning Electron Microscope images taken by Ilka Weikusat at the University of Utrecht in 2011. The sample from a depth of 2035.9 m is from the European Project for Ice Coring in Antarctica in Dronning Maud Land (EDML) deep ice core, drilled between 2001 and 2006 at Kohnen Station, Antarctica. The SEM-images were created in preparation for Electron backscatter diffraction measurements and show ice grain boundaries, frost and a filament at a grain boundary. M. Drury and G. Pennock provided the infrastructure for Cryo-SEM work, which was conducted at EM square, the electron microscopy facility of Utrecht University Weikusat et al. (2017).6_Ramam_multiplot.jpg were created by Nicolas Stoll in March 2020 at the Alfred Wegener Institute, Bremerhaven using Cryo-Raman spectroscopy to identify the chemistry of micro-inclusions in an ice sample from a depth of 757.4 m from the EGRIP ice core, NE-Greenland. A) and B) show the location of micro-inclusions and C) is the derived Raman spectra of the micro-inclusion in B), which was identified as Quartz.
