title: Database of growth and survival behavier of sea cucumber larvae Isostichopus sp. cultivated under different densities, temperatures and diets

description: Isostichopus sp. is a variety of Isostichopus badionotus, proposed as a new species, which has been intensely fished in the Colombian Caribbean, arousing interest for its aquaculture. This study evaluated the effect of two culture densities (1-3 larvae ml-1), two temperatures (23 and 26°C) and two microalgae diets (Isochrysis galbana, Chaetoceros calcitrans, Nannochloropsis oculata 1:1:1 and I. galbana, C. calcitrans 1:1) on the survival, development and growth of its larvae.

title: Reconstructions of sea-surface parameters from sediment core MSM05/3_343310 from Disko Bugt, West Greenland

description: Palynological analyses of sediment core MSM343310 from Disko Bugt (68°38.861' N, 53°49.493' W) document decadal‐ to centennial‐scale variability of sea surface conditions during the last ~3,600 years. Dinocyst fluxes (&gt;10⁴ cysts/cm² yr⁻¹) indicate a very high productivity. Dinocyst assemblages dominated by Islandinium minutum, Brigantedinium spp., Islandinium? cezare, and the cyst of Pentapharsodinium dalei suggest low surface salinity and marked shifts in summer sea surface temperature. The application of the modern analog technique to dinocyst assemblages, using an updated reference data set with new sites from the West Greenland margin, led to reconstruct decadal‐centennial‐scale variations in sea surface salinity and temperature, in phase with the δ18O variations in the Camp Century ice core. At ~1.5 ka BP, the seasonal sea ice cover records an important regime change, from winter‐only sea ice to more unstable conditions marked by successive cooling pulses with sea ice cover of up to 8 months/yr. The data suggest a close relationship between hydrographic conditions and regional climate over Greenland. Our record shows variations with a mean 200 years periodicity until ~2 ka BP, which supports the hypothesis of climate variations driven by solar variability. After 1.5 ka BP, our data show a variability characterized by a 60-70 year periodicity, which suggests linkages with the Atlantic Multidecadal Oscillation and southwestward migration of the atmospheric polar front. The most recent part of the record, from ~1900 CE to 2007 CE, is characterized by assemblages reflecting warmer surface conditions and reduced sea ice cover.

title: Raw data to peat cosm analysis from the Meadowlands in Minnesota, USA

description: Globally important carbon (C) stores in northern peatlands are vulnerable to oxidation in a changing climate. A growing body of literature draws attention to the importance of dissolved organic matter (DOM) in governing anaerobic metabolism in organic soil, but exactly how the reduction-oxidation (redox) activities of DOM, and particularly the phenolic fraction, are likely to change in an altered climate remain unclear. We used large mesocosms in the PEATcosm experiment to assess changes in peatland DOM and redox potential in response to experimental manipulations of water table (WT) position and plant functional groups (PFGs). WT position and PFGs interacted in their effects on redox potential and quantity and quality of DOM. Phenolics were generally of higher molecular weight and more oxidized with sedges in lowered water tables. Altered DOM character included changes in dissolved nitrogen (N), with higher N:phenolics with higher E4:E6 (absorbance ratio = 465:665) DOM in the lowered WT and sedge PFG treatments. Conversely, biomolecular assignments to free amino-sugars were largely absent from low WT treatments. Drainage resulted in the creation of unique N compounds which were more condensed (lower H:C), that changed with depth and PFG. The accumulation of oxidized compounds with low WT and in sedge rhizospheres could be very important pools of electron acceptors beneath the water table, and their mechanisms of formation are discussed. This work suggests the effects of changes in vegetation communities can be as great as WT position in directly and interactively mediating peat redox environment and the redox-activity of DOM.

title: A high-resolution (0.25 degree) historical global gridded dataset of monthly and annual cooling and heating degree-days (1970-2018) based on GLDAS data

description: Users are recommended to consult the author (malcolm.mistry@unive.it / malmistry1977@gmail.com) for an updated version which includes more recent years.Monthly and Annual Cooling/Heating degree-days (CDD/HDD) using daily average temperature (°C), and Cooling degree-days using daily average wet-bulb temperature (Twb), based on the following threshold (base) temperatures:CDD, CDDwb: 18, 18.3, 22, 23, 24 and 25 (°C)HDD: 10, 15, 15.5, 16, 17 and 18 (°C)The degree-days are computed using meteorological parameters from the Global Land Data Acquisation System (GLDAS) ver. 2 (@ 0.25 degree global gridded resolution). The dataset referred to as "DegDays_0p25_1970_2018" covers 49 years over the period 1970-2018.Units: Degree-Celsius Days. In order to convert to Degree-Fahrenheit Days, multiply by 1.8. e.g. CDD (°F) = 9/5* CDD (°C)Data files are compressed in tar.bz2 folder containing the individual NetCDF-4 (.nc4) and GeoTIFF (.tif). The files follow the naming convention 'gldas_0p25_deg_DD_base_T_degC_1970_2018_timescale.nc4'; wherein “DD” is the abbreviation of the index (CDD, CDDwb or HDD), degC is the threshold temperature used in the computation of Tb, and “timescale” either “ann” or “mon” relating to annual or monthly timescales over which the corresponding degree-days are computed. Grid-cells with missing values are identified by “1.e+20f”.Important: GLDAS ver-2 comprises of two sub-versions (ver. 2.0 for period 1970-2010 and ver 2.1 for period 2000-present day). The degree-days computed using the input temperature and variables may show a break in time-series at a few locations around the years 2010-11. Users are therefore advised caution when using the data for trend analysis for instance. Further details on the merging of the two versions can be found below:https://disc.gsfc.nasa.gov/information/faqs?title=Should%20I%20use%20GLDAS%20Version%202.0%20(GLDAS-2.0)%20or%20GLDAS%20Version%202.1%20(GLDAS-2.1)%3F

title: Submarine Permafrost Map (SuPerMAP), modeled with CryoGrid 2, Circum-Arctic

description: This data set contains a first‐order estimate of distribution, thickness and ice-content of submarine permafrost on the Arctic shelf based on a numerical heat transfer model. Our model uses dynamic upper boundary conditions that synthesize Earth System Model air temperature, ice mass distribution and thickness, and global sea level reconstruction and applies globally distributed geothermal heat flux as a lower boundary condition. Sea level reconstruction accounts for differences between marine and terrestrial sedimentation history. Sediment composition and pore water salinity are integrated in the model. Model runs for 450 ka for cross‐shelf transects were used to initialize the model for circumarctic modeling for the past 50 ka.This data set consists of current sea levels, and permafrost depth [m below sea floor(m bsf)], total ice-content [m³ / m²] and enthalpy [MJ / m²] at times 50ka, 25ka and 0a before industrialization for 15892 locations on the Arctic shelf. Additionally zonations for permafrost depth and ice-content are given as layer files. Based on the undertaken sensitivity studies zones with &lt;100m permafrost are uncertain, zones with 100-300m are probable, and zones with &gt;300m are confident.

title: Demonstration code and input data for Matrix-based sensitivity assessment of soil organic carbon storage: A case study from the ORCHIDEE-MICT model

description: Modeling of global soil organic carbon (SOC) is accompanied by large uncertainties. The heavy computational requirement limits our flexibility in disentangling uncertainty sources especially in high latitudes. We build a structured sensitivity analyzing framework through reorganizing the ORCHIDEE-MICT model with vertically discretized SOC into one matrix equation, which brings flexibility in comprehensive sensitivity assessment. Through Sobol's method enabled by the matrix, we systematically rank 34 relevant parameters according to variance explained by each parameter and find a strong control of carbon input and turnover time on long-term SOC storages. From further analyses for each soil layer and regional assessment, we find that the active layer depth plays a critical role in the vertical distribution of SOC and SOC equilibrium stocks in northern high latitudes (&gt;50˚N). However, the impact of active layer depth on SOC is highly interactive and nonlinear, varying across soil layers and grid cells. SOC from regions with low active layer depth (e.g., the northernmost part of America, Asia and some Greenland regions) is most vulnerable to active layer depth in terms of relative changes. The model is sensitive to the parameter that controls vertical mixing (cryoturbation rate) but only when the vertical carbon input from vegetation is limited since the effect of vertical mixing is relatively small. And the current model structure may still lack mechanisms that effectively bury non-recalcitrant SOC. We envision a future with more comprehensive model inter-comparisons and assessments with an ensemble of land carbon models adopting the matrix-based sensitivity framework.

title: (Table 1) Mean sizes of Hydrobia ulvae juveniles in the littoral zone of the Chernaya Inlet (Kandalaksha Bay, White Sea) in July-September 1995

description: Based on observations and experiments carried out within the White Sea silty-sandy littoral zone in 1994-1997 data on biology of development and behavior of Hydrobia ulvae juveniles over water column and in sediments were obtained. Hydrobiid juveniles 0.125-0.150 mm in size appear in plankton during the second half of June and in two to three weeks they precipitate on sediments reaching 0.300-0.350 mm in size. Specific biological features of the White Sea hydrobiids are a short reproductive period and a short period of juvenile growth related to long under-ice time and decelerated warming of shallow waters. Distribution of juvenile individuals of H. ulvae is primarily determined by hydrodynamics and microtopography of the littoral zone. Redistribution of the juveniles permanently takes place, since all size groups of the juveniles are equally subjected to migration. During the first few weeks after settling mortality of juvenile mudsnails is 85%.

title: SHYFEM model results for the Po River-Delta-Sea system, link to NetCDF files

description: This dataset includes the results of the application of the SHYFEM numerical model to the Po River-Delta-Sea (RDS) system (Italy). The hydrodynamics and the interaction between riverine and marine waters in the system were studied through the application of the unstructured finite elements 3D numerical model to a domain comprising the Po river branches, 7 coastal lagoons and the shelf sea. The vertical structure of the model is z-levels, with 1 m thickness up to 10 m depth, 2 m thickness up to 26 and finally 4 m thickness to 34 m depth. The model was forced with real data of water levels, meteorological parameters and freshwater inputs. The simulations included the baroclinic gradients in the hydrodynamics calculations induced by mixing of riverine and sea waters, and by heat fluxes with the atmosphere.Two simulations were run, one for the model calibration (March - September 2009) and a two year long simulation (2010-2011) for the model validation and analysis. The SHYFEM parameter files of the two simulations are included in the data archive.The dataset includes the time-averaged hydrodynamic and T/S fields of the two simulations and of a relevant river flood in May 2009. For the 2010-2011 simulation we also provide the Water Renewal Time distribution and its range of variability.The model values calculated on the triangular finite elements grid (scalar values on the nodes and velocities on the elements) were converted into a regular grid netcdf format with horizontal spacing of 100 m. The reference coordinate system is EPSG 3003.
