title: Dissolved concentrations of CH4, nutrients, and biological parameters in the water column of twelve Mediterranean reservoirs in Southern Spain

description: We sampled twice 12 reservoirs between July 2016 and August 2017 in southern Spain during the summer stratification and the winter mixing. We determined reservoir area, perimeter, and capacity using the next open databases: Infraestructura de Datos Espaciales de Andalucía (IDEAndalucia; http://www.ideandalucia.es/portal/web/ideandalucia/), and the Ministerio para la Transición Ecológica (https://www.embalses.net/). The reservoir volume (m3) divided by its surface area (m2) will yield the mean depth (m). We also calculated the shoreline development ratio (DL) (Aronow, 1982) and the shallowness index (1/m) by dividing the shoreline development index (DL) by the mean depth (m). We performed the vertical geochemical profiles of the reservoirs using a Seabird 19plus CTD profiler and obtained the measurements of temperature and dissolved oxygen. We collected samples at different depths for dissolved CH4 analysis in air-tight Winkler bottles by duplicate, preserved with a solution of HgCl2 (final concentration 1mM) to inhibit biological activity and sealed with Apiezon® grease to prevent gas exchange. We measured dissolved CH4 using headspace equilibration and gas chromatography (2-3 replicates per bottle). We measured DIC, DOC, TN, and TDN by high–temperature catalytic oxidation using a Shimadzu total organic carbon analyzer (Model TOC-V CSH) coupled to nitrogen analyzer (TNM-1). We determined the NO3 concentration using the ultraviolet spectrophotometric method, using a Perkin Elmer UV-Lambda 40 spectrophotometer at wavelengths of 220 nm and correcting for DOC absorbance at 275 nm (APHA, 1992). We measured NH4 and NO2 concentrations by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). Dissolved inorganic nitrogen (DIN) is the addition of the NO3, NH4, and NO2 concentrations. We measured total phosphorus (TP) concentration by triplicate using the molybdenum blue method (Murphy and Riley, 1962) after digestion with a mixture of potassium persulphate and boric acid at 120 °C for 30 min (APHA, 1992). We determined chlorophyll-a concentration by extracting the pigments from filters with 95% methanol in the dark at 4 °C for 24 h (APHA, 1992). We measured chlorophyll-a (Chl-a) absorption using a Perkin Elmer UV-Lambda 40 spectrophotometer at the wavelength of 665 nm and for scattering correction at 750 nm. . To obtain the integrated mean of chlorophyll-a (μg Chl-a /l), from the discrete points along the water column, we used the trapezoidal rule (León-Palmero et al., 2019). To obtain the cumulative chlorophyll-a concentration in the whole water column (mg Chl-a/m2), we summed the concentration of chlorophyll-a from each stratum using the trapezoidal rule, as we did for the integrated chlorophyll-a before, but we omitted the division between the maximum depth. We determined the abundances of cyanobacteria and photosynthetic picoeukaryotes using flow cytometry (FACScalibur) using unfiltered water.

title: UFRB-ESD (UFRB Emergency Sound Dataset)

description: This is the UFRB-ESD (UFRB Emergency Sound Dataset), an open-access audio resource developed as part of an undergraduate thesis (Final Project) in Computer Engineering at the Universidade Federal do Recôncavo da Bahia (UFRB), Brazil.

The dataset was created to address the gap in datasets focused on short-duration emergency sounds, aiming at the development of assistive technologies for the hearing impaired (e.g., low-latency wearable devices).

Dataset Content:





2,849 audio clips in .wav format (16kHz, mono).




Standard Duration: 1 second per clip.




9 Classes: buzina (horn), tiro (gunshot), explosão (explosion), sirene (siren), grito (scream), colisão (crash/collision), freio (brakes), cachorro (dog bark), and outros (other/non-emergency sounds).



All clips were collected from public sources and underwent a manual curation and validation process. The dataset was validated with four deep learning architectures (MLP, 2D CNN, ResNet-18, ResNet-50), achieving a maximum accuracy of 86.67% (ResNet-18), which confirms its viability and challenging nature for classification tasks.

description: The relative contents of major and trace elements were analyzed in 2019 with an X-Ray Fluorescence (XRF) at 1-mm resolution on the surface of each sediment core with an Avaatech Core Scanner (EDYTEM Laboratory). The split-core surface was first covered with a 4-μm-thick Ultralene film to avoid contamination and desiccation of the sediment. Element intensities are expressed in counts per second (cps). Different settings were used with 10 kV and 0.2 mA during 15 s to detect Al, Si, S, K, Ca, Ti and at 30 kV and 0.3 mA during 20 s for Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, Zr, Pb (Richter et al., 2006; doi:10.1144/GSL.SP.2006.267.01.03).

title: Nematoda diversity and functional feeding groups on the Northeast Greenland (NEG) shelf during POLARSTERN cruise PS109

description: Between September and October 2017, MUC cores were deployed at various locations across the Northeast Greenland (NEG) shelf with R/V Polarstern during PS109. Samples for meiofauna were collected with a cut-off 10 ml syringe (area 1.89 m²) that was inserted to 5 cm depth sediment depth in the MUC core, and subsequently sliced in 5 horizons of 1 cm. Afterwards, meiofauna were extracted from the samples by triple density centrifugation with the colloidal silica polymer LUDOX TM 40 (Heip et al., 1985) and rinsed with freshwater on stacked 1 mm and 32 µm mesh sieves. The fraction retained on the 32 µm mesh sieve was preserved in 4 % Li2CO3-buffered formalin and stained with Rose Bengal. Nematodes of each sample were handpicked with a fine needle, transferred to glycerine (De Grisse I, II and III) (Seinhorst, 1959) , mounted on glass slides, identified to genus level and allocated to functional feeding groups based on Wieser, 1953 (as selective deposit feeders - 1A, non-selective deposit feeders - 1B, epistratum feeders - 2A and predators/scavengers - 2B).

title: Single prokaryotic cell abundances of the Northeast Greenland (NEG) shelf sediments from POLARSTERN cruise PS109

description: Samples for single cell abundances as an estimate for the abundance of benthic bacteria on the Northeast Greenland shelf have been collected with R/V Polarstern during PS109 between September and October 2017 using a camera-equipped multiple corer (TV-MUC; core area 0.007 m²). Upon arrival on deck, the upper 5 cm of three MUC cores were sliced into 1 cm layers with a 10 ml cut-off syringe. 2 ml of each slice was transferred into a scintillation vial and fixed with 2 % filtered formaldehyde-seawater solution. In the laboratory, the samples were diluted, filtered through polycarbonate filters (0.2 µm, Whatman Nucleopore Track-Etch Membrane) and stained with a 0.001 % acridine orange solution after Hobbie et al., 1977 (doi:10.1128/aem.33.5.1225-1228.1977). Cells were counted on at least 30 grids (125 µm * 125 µm area) for 2 replicate filters per sample each with a Zeiss Axiophot microscope (Germany) and a 100x oil immersion objective lens (Zeiss Plan-Apochromat, Germany).
