title: EPICA EDML chemical concentrations and fluxes

description: Sea salt Na+ and nss Ca2+ data from the EPICA DML (EDML) ice core over the last 150000 yr in 1 m resolution. Data has been calculated from raw data as described in the manuscript. Top 450 m have been averaged from high resolution data after correction for interlaboratory offsets. Negative concentrations after correcting for crustal sodium and sea salt calcium, respectively, have been replaced by zeros. Missing values occur due to sample loss, bad core quality or contamination during sample preparation.

title: Snow height on sea ice and sea ice drift from autonomous measurements from buoy 2018S58, deployed during POLARSTERN cruise PS111

description: Snow height was measured by the Snow Depth Buoy 2018S58, an autonomous platform, drifting on Antarctic sea ice, deployed during POLARSTERN cruise PS111. The resulting time series describes the evolution of snow depth as a function of place and time between 19 Feb 2018 and 10 June 2018 in sample intervals of 1 hour. The Snow Depth Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed on first year ice. In addition to snow depth, geographic position (GPS), barometric pressure, air temperature, and an internal ice temperature were measured. Negative values of snow height occur if surface ablation continues into the sea ice. Thus, these measurements describe the position of the sea ice surface relative to the original snow-ice interface. Differences between single sensors indicate small-scale variability of the snow pack around the buoy. The data set has been processed, including the removal of obvious inconsistencies (missing values). Records without any snow depth may still be used for sea ice drift analyses.

title: Clay mineral determination of sediment core GeoB13861-1

description: Device: PANalytical EMPYREAN; CuK[Alpha] radiation (40 kV, 40 mA)Method: Each sample was analyzed between 2.5° and 29° 2 Theta, with a step size of 0.013° in the air-dried state and after ethylene glycol solvation. X-ray diffraction measurements were performed on organic and carbonate-free, preferentially oriented clay-size filer cakes (&lt; 2 µm) with molybdenite as an internal standard. Further details of sample preparation techniques are described in Petschick et al. [1996] and Diekmann and Kuhn [1999]. Diffractograms were evaluated using the "MacDiff 4.2.5" software [Petschick et al., 1996] without using a weighted average smoothing but applying a molybdenite (006) peak correction.

title: Stable isotope data of mesozooplankton from the Adriatic basin (Mediterranean Sea)

description: Zooplankton plays a key role in the marine food webs, and it represents the main food source for small pelagics, one of the most exploited resources in the Adriatic Sea. In order to deepen our knowledge of zooplankton assemblage structure and trophodynamics in one of the most productive areas of the Mediterranean sea, but at the same time highly impacted by human activities, community and Stable Isotope Analyses (SIA) were performed on zooplankton samples. Here SIA data are provided. Zooplankton samples were collected on board R/V G. Dallaporta during the acoustic survey MEDIAS 2019 geographic subarea (GSA) 17 and GSA 18 (Leonori et al., 2021, https://doi.org/10.12681/mms.26001) that took place in June–July 2019, in the continental shelf waters of the western Adriatic Sea. Vertical hauls were performed using a WP2 plankton net, starting from 3 m above the bottom (or from 100 m depth in the deepest hauls), to the surface. Zooplankton samples were frozen on board and analysed in the laboratory to characterize the planktonic community, both at assemblage and trophic structure levels. After taxonomical identification, samples were dried and analysed through an elemental analyser (Thermo FlashEA 1112) for the determination of total carbon and nitrogen and then analysed for δ13C and δ15N in a continuous-flow isotope-ratio mass spectrometer (Thermo Delta Plus XP) (Post et al., 2007, https://doi.org/10.1007/s00442-006-0630-x).

The stable isotope ratio was expressed, in relation to international standards (atmospheric N2 and Pee Dee Belemnite for δ15N and δ13C, respectively), where R is δ13C or δ15N: (R_sample/R_standard)-1)*10e3. Analytical precision based on standard deviations of internal standards (International Atomic Energy Agency IAEA-CH-6, IAEA-NO-3, and IAEA-N-2) ranged from 0.10 ‰ to 0.19 ‰ for δ13C and 0.02 ‰ to 0.08 ‰ for δ15N.

title: Jellyfish abundance and Chlorophyll a data from a shallow semi-enclosed cove, Kertinge Nor, Denmark

description: Carnivorous gelatinous zooplankton (GZ) can be very abundant in marine ecosystems around the globe and exert considerable predation pressures on micro- to macrozooplankton as well as larval and juvenile fish. As these species are in many cases intermediate and top predators, their biomass can be easily evaluated, which could indicate overall food web stability or alteration. There is growing concern worldwide about increasing abundances of GZ species and consequently negative impacts on food webs and human coastal zones activities. In this paper, I present a case study from a shallow Danish cove and a long-term record spanning 29 years (1991-2019) obtained by unconventional means. Jellyfish were collected using horizontal sub-surface net tows in August and September during a summer student class. Sea surface temperature and chlorophyll a concentration were measured in parallel. No clear long-term trend in jellyfish biomass could be seen, whereas the values were highly variable from year to year. This is in contrast with other published Scandinavian long-term GZ time series. Sea surface temperature and chlorophyll a concentration had significant (and interactive) effects on the jellyfish biomass in Kertinge Nor. The scarcity and shortness of GZ long-term series do not allow solid conclusions in most marine ecosystems, so it becomes clear that publishing time series (even with small spatial extent) can contribute to improve the perception of interannual GZ population developments. Thus, I strongly recommend extending monitoring activities, explicitly including GZ taxa, in as many marine ecosystems as feasible.

title: Fluorescence of alkaline-extractable organic matter from a sediment core collected in the Baltic Sea

description: In this study organic mater fluorescence is characterized by excitation-emission matrix spectroscopy on alkaline extracted DOM from a Baltic Sea sediment core that spanned 8500 years and fluctuating levels of hypoxia. Our results showed that three underlying components had strong correlations with carbon, nitrogen content and δ15N. Our results demonstrate that optical properties of extracted OM from sediments reveal information about OM quality and quantity similar to those of biomarkers, which can be a useful additional tool for investigating OM deposition.

title: Carnivoran bony labyrinth morphometry and characteristics

description: Carnivora is a highly diverse and successful group of mammals representing key stone predators in food webs. They originated in the Palaeocene and developed numerous lifestyles, locomotion modes and hunting strategies during their evolutionary history. Mechanosensory organs, as the inner ear (senses of equilibrium and hearing) represent essential anatomical systems to obtain insights into function, ecology and phylogeny of extant but also extinct vertebrates. Here, we examined bony labyrinths of a broad sample of extinct and extant carnivoran species using µCT scans to obtain new information about hunting behaviours of these ancient carnivorans. Bony labyrinths were digitally reconstructed and measurements were taken directly on these 3D models. Principal component analyses evidently separate morphospaces based on various hunting strategies (pursuit, pounce, ambush and occasional) but also support their phylogenetic relationships (Canoidea vs. Feloidea). The height, width and length of the semicircular canals show functional morphological adaptations, whereas the diameter of the canals, the height of the cochlea and particularly the angle between the lateral semicircular canal and the cochlea indicate a phylogenetic signal. The results demonstrate that the bony labyrinth provides a powerful ecological proxy reflecting both predatory habits as well as phylogenetic relationships in extinct and extant carnivorans.

title: Global data set of urban/rural agglomeration units

description: Urban studies often rely on urban boundaries that have been defined by administrative units or by land use or land cover classification of satellite images. The final results of those boundaries is the categorization of urban/non-urban units in the form of a binary layer used to extract additional information (e.g., zonal statistic) from other geographical layers (e.g., land surface temperature or population density). Given the heterogeneous and continuous nature of the built-up area, binary representations contain a mixture of urban/non-urban areas that influence the results of following analyses. Here we present a way to move beyond the limitations of the binary urban/non-urban representations with a hierarchical watershed-based thresholding and segmentation approach that partitions the built-up area into more homogeneous units. The proposed algorithm, applied to the Global Human Settlement Layer, enables researchers and planners to define urban computational units in three ways - bin-unit, watershed-unit, and agglomeration-unit - depending on need and scale of analyses. We provide suggested terminology and notation style for this cross-over application of a specialized watershed algorithm. Among other possible applications, the resulting segmented, binned and agglomeration units offer alternatives to existing patch analysis methods for drawing relationships between patterns of urban development and ecological or environmental attributes.

title: Model experiment on optimal size of a fish stock with environmental uncertainties

description: We analyze the effect of environmental uncertainties on optimal fishery management in a bio-economic fishery model. Unlike most of the literature on resource economics, but in line with ecological models, we allow the different biological processes of survival and recruitment to be affected differently by environmental uncertainties. We show that the overall effect of uncertainty on the optimal size of a fish stock is ambiguous, depending on the prudence of the value function. For the case of a risk-neutral fishery manager, the overall effect depends on the relative magnitude of two opposing effects, the 'convex-cost effect' and the 'gambling effect'. We apply the analysis to the Baltic cod and the North Sea herring fisheries, concluding that for risk neutral agents the net effect of environmental uncertainties on the optimal size of these fish stocks is negative, albeit small in absolute value. Under risk aversion, the effect on optimal stock size is positive for sufficiently high coefficients of constant relative risk aversion.
