title: Black soldier fly turns agro-industrial food waste into organic fertilizer: cost- and eco-effectiveness from a circular economy perspective

description: The sustainable utilization of black soldier fly (BSF) for recycling organic waste into high-quality protein feed and organic fertilizer with a low environmental footprint is gaining momentum worldwide. Although BSF farming is becoming a rapidly growing agribusiness, studies on BSF farming's economic aspects are limited. This study analyses the economic implications of farming BSF for animal feeds and frass fertilizer (FF) production to provide evidence of the economic benefits using experimental data. The BSF larvae were reared using brewery spent grain amended with sawdust, biochar, and gypsum, to determine the best waste combination for cost-effective production. The agronomic performance of FF on the maize crop was assessed using field experiments. Our results demonstrated that the rearing substrate accounts for 81 - 90% of the total BSF production cost. The utilization of frass fertilizer as an additional value-added product would increase farmer's net income by 5 - 15 folds compared to BSF farming alone. Feedstock amended with 20% biochar increased net income by 10 - 64% for BSF larvae and FF production compared to other feedstocks. Production of 1 tonne of dried BSF larvae (US$ 900) would generate 10 - 34 tonnes of frass fertilizer worth US$ 3000 - 10,200. Maize grown on plots treated with FF yielded 29 - 44% higher net income than plots amended with commercial organic fertilizer. Furthermore, smallholder insect farmers' direct use of FF for maize production would generate 30 - 232% higher net income than farmers purchasing similar FF. Our results demonstrate for the first time the role of insect farming in circular economy and justify the opportunities for future investments that would lead to enhanced sustainability for agricultural and food systems, especially for smallholder farmers in low- and middle-income countries.

title: Mass and volume time series of Antarctic drainage systems derived by a coupled state space analysis of satellite observations and model products

description: We investigated time series of 17 Antarctic drainage basins from April 2002 until August 2016 using data from the satellite gravimetry mission GRACE, a multi-mission altimetry product, and products from regional climate and firn modeling. The model products are cumulated surface mass balance anomalies (cSMBA) derived from RACMO2 outputs and firn thickness change predicted by the firn densification model (FDM) IMAU-FDM. We simultaneously evaluated these data sets in a state-space model framework to separate time-variable contributions from ice-dynamics and climatological forcing to mass and volume changes of the drainage systems. We parametrize long-term changes by a trend with a time-variable rate. Further we separate residual cyclic, first-order auto regressive (AR(1)), and irregular short-term variations.For each drainage basin we provide a file that includes mass and volume time series of the input data sets and the estimated signals along with their uncertainty (single standard deviation). The basin numbers refer to drainage systems defined by Zwally et al. (2012).

title: Biomarker and foraminifera assemblage data from MD99-2269 and JR51-GC35, North Iceland Shelf

description: These data include highly-branched isoprenoids (IP25, HBI II, HBI III and HBI IV) and isoprenoid GDGTs from marine sediment cores MD99-2269 and JR51-GC35 from the North Iceland Shelf. Total lipids were extracted and purified following standard procedures on an ASE and using silica-gel columns, respectively. HBIs were then analyzed on GC-MS and GDGTs on HPLC-MS. Both records have age models derived from radiocarbon-dated molluscs and foraminifera that are published elsewhere, and the above lipid biomarker records cover the last 8000 years. Temporal resolution varies between multi-centennial to sub-centennial. From MD99-2269, data also include complete planktic and benthic foraminifera assemblages. Foraminifera were wet-picked from sediment subsamples. Using established transfer functions, we also present SST and BWT records derived from the planktic and benthic foraminifera assemblages, respectively. Planktic assemblage data cover the last 10000 years whereas benthic assemblage data only cover the last 8000 years. Temporal resolution varies between multi-centennial to sub-centennial. These data were collected in order to document the Holocene paleoceanography of the North Iceland Shelf. In other words, to study when Arctic/Polar versus Atlantic Waters bathed the region, how the temperatures of these currents changed, when and how sea ice was advected to the region, and how pelagic productivity was impacted by all these oceanographic variables.

title: Net community production, nutrients and hydrographic parameters in the South China Sea in October 2014 and June 2015

description: Net community production (NCP) corresponds to the difference between photosynthesis and respiration and can be estimated based on the dissolved oxygen to argon ratio (O2/Ar) in the mixed layer. NCP is also an important proxy for the biological pump in the ocean. In order to figure out the influencing factors on NCP and its seasonal variation in the northern slope region of the South China Sea (SCS), we conducted high-resolution underway measurements of O2/Ar and hydrographic parameters using membrane inlet mass spectrometry and multi-parameter water quality logger in the northern slope region of the South China Sea (SCS) in October 2014 and June 2015, assisted by nutrient measurement. Net community production (NCP) in the mixed layer was estimated using the supersaturation of O2/Ar (Delta O2/Ar) and gas transfer velocity (k). All the underway data were compiled into the 5-min interval. Surface water samples for the nutrient analysis were collected from Niskin bottles mounted on the conductivity–temperature–depth (CTD) instrument at sampling stations, the nutrients were then photometrically determined by an auto-analyzer. The mixed layer depth (MLD) and the euphotic depth (Zeu) were calculated at stations where CTD casts were made based on potential density and chlorophyll fluorescence respectively.

title: Snow depth, sea ice thickness and C- and X-band backscattering over Nunavik Fjords of the Hudson Strait

description: This data collection presents snow depth, ice thickness and RADARSAT-2 (RS2) and TerraSAR-X (TSX) backscattering coefficient data over selected homogenous first-year smooth and undeformed sea ice areas in Salluit, Deception Bay and Kangiqsujuaq. These study sites are fjords of the Hudson Strait located in Nunavik. The data covers three winter seasons: 2016, 2017, 2018. Snow depth and ice thicknesses were measured at roughly 30 locations covering each site, twice per season (in January-February and April-May), by direct measurements. High-resolution SAR images were acquired from December to May every 24 days for RS2 and every 11 days for TSX. Data is presented for HH, HV, VV, co-polarization ratios and Cloude-Pottier decomposition parameters for the Wide-Fine Quad-Pol RS2 data, and for the HH backscattering coefficient for the Stripmap TSX data. These acquisitions were made to explore the relationship between snow depth, ice thickness and SAR. For the "SAR parameter statistics at AOI for RADARSAT-2 and TerraSAR-X" dataset, pixel median value was computed over areas of interest (AOIs) roughly 120 by 100 m and each containing between 600 and 650 pixels were distributed over the homogeneous study areas in a grid-like pattern with 0.7 to 1 km separation, avoiding special features like the shore or a ship's track. The Salluit, Deception Bay, and Kangiqsujuaq study areas counted 35, 43, and 78 AOIs, respectively. For the "SAR parameter values at measurement locations" files, pixel values were averaged over a 3x3 window for RS2 (576 m2) and a 9x9 window for TSX (506 m2). This data collection contains supplementary materials to Dufour-Beauséjour et al (2021).

title: Reconstruction of a reliable long daily rainfall dataset for the Northeast India (NEI) for climate change impact and extreme rainfall studies

description: For both food security and biodiversity management in NEI, a biodiversity hot spot, is required dependable, consistent estimates of trend and modes of variability of rainfall, so that policy makers have an idea of the rainfall that can be expected during the coming decades. Hence, daily rainfall data over the North East India (NEI) for more than 100 years is required for any climate change impact assessment. However, the region is poorly sampled and none of the weather stations have operated continuously for such a period. This technical note describes combining conventional weather station records with rain-gauge records from a number of sources like privately owned tea estates to create a continuous daily rainfall record from 1 January 1920-31st December 2009 for the north-eastern region of India. We have been successful in creating a daily rainfall data set on a set of 24 well distributed fixed stations. The data extent back into the 1920 and stem from a variety of station observations. Remaining data gaps are less than 3% of the total data in each station. Every effort has been made to reconstruct the data gaps with the aim to improve assessments of the long-term changes in climate variability in NEI. The final reconstructed data set for NEI is well suited to estimate both long-term trend and multi-decadal variability of rainfall over the region.

title: Coastal hypoxia and eutrophication as key controls on benthic release and water column dynamics of iron and manganese

description: Continental shelves are a major source of iron (Fe) and manganese (Mn) to marine waters. Here, we investigate controls on benthic release of Fe and Mn and the impact on the water column in the Baltic Sea. We find high in situ benthic release rates of dissolved Fe and Mn at seasonally hypoxic sites (bottom water oxygen between 0-63 μmol L−1) receiving high inputs of organic matter. We find that benthic Fe and Mn release is sensitive to bottom water oxygen concentrations. Benthic Fe release is likely additionally controlled by Fe-sulfur redox chemistry in the surface sediment. For Mn, benthic release correlates positively with Mn oxide availability in the surface sediment. Benthic release contributes to high dissolved Fe and Mn concentrations in the water column and is amplified by repeated cycling of Fe and Mn between the sediment and overlying water through benthic release, oxidation in the water column, deposition as metal oxides, followed by reductive dissolution. Most water column Fe ( 80%) is present in particulate form near the seafloor. In contrast to Fe, a large percentage of the Mn remains dissolved ( 50%). We show that easily reducible Fe and Mn oxides are key forms of particulate Fe and Mn in suspended matter. The Baltic Sea represents a highly eutrophic, low oxygen end-member when compared to other modern coastal systems. Our results imply that, upon continued eutrophication and deoxygenation of the coastal ocean, benthic release of dissolved Fe and Mn from continental shelves could become greater than previously thought.

title: Climate model (Consortium for Small-scale Modeling, COSMOS) results of different Laurentide Ice Sheet reconstructions during the Last Glacial Maximum in NetCDF format

description: Herein, we publish the simulated global annual mean sea surface temperature (THO), surface air temperature (SAT) over a time period of 100 years retrieved from equilibrium climate simulations for the Last Glacial Maximum (~21 ka BP). We investigate the range of temperature variability that occurs in response to uncertainties in the boundary conditions of Laurentide ice sheet (LIS). We performed LGM simulations, applying six different LIS reconstructions (ICE-6g, GLAC-1a, ANU, Gowan, Licciardi and PMIP3) in a fully coupled atmosphere-ocean-sea-ice model. The model data has been used in the publication by Hossain et al., 2021. The climate data has been produced with Consortium for Small-scale Modeling (COSMOS; ECHAM5/JSBACH/MPIOM/OASIS3), utilized at a resolution of T31 in the atmosphere with 19 vertical layers and a resolution of GR30 (~3.0°x1.8°) in the ocean with 40 vertical layers. The model setup refers to boundary conditions (terrestrial topography, ocean bathymetry), greenhouse gas concentrations (CO2 = 185 ppm; CH4 = 350 ppb; N2O = 200 ppb) and orbital forcing representative for the LGM and are imposed in accordance with the PMIP3 protocol. We also run COSMOS using PI boundary conditions (ice-sheet topography, orbital forcing, greenhouse gas concentrations and ocean bathymetry). Details on setup and identifiers of LGM model simulations can be found in Table S1 of Hossain et al., 2021.
