Suomi-NPP VIIRS Global Mapped Normalized Difference Vegetation Index Data provides satellite-derived Earth observation data from the VIIRS instrument. The dataset includes vegetation indices and sea surface temperature retrieved with a triple-window thermal-infrared algorithm for improved atmospheric correction. VIIRS is the successor to MODIS, offering 22 spectral bands at moderate and image resolutions.
Morphological measurements of adult and sub-adult Red handfish (Thymichthys politus) and Spotted handfish (Brachionichthys hirsutus) were collected from preserved specimens and underwater images. The data, associated with the NESP MB A10 project, was gathered to investigate if external morphometrics can determine sex. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-06-04.
Over 10,000 per- and polyfluoroalkyl substances (PFAS) have predicted no-observed-effect concentrations (NOECs) for fish mortality, generated by a machine learning model. The model, developed by Minhao Wang and uploaded in May 2026, used molecular structural descriptors and achieved a test R² of 0.7096. Predictions were extrapolated to 12 additional fish species using trait-based inference, revealing toxicity variations linked to chemical chain length and species traits like diet and temperature preference.
Machine learning-predicted no-observed-effect concentrations (NOECs) for 10,863 per- and polyfluoroalkyl substances (PFAS) in Danio rerio (zebrafish), with extrapolations to 12 additional fish species. The model uses compiled toxicity data and molecular structural descriptors, achieving a test R² of 0.7096. The dataset was created by Minhao Wang and last updated on 2026-05-21.
145 specimens from 85 marine species collected in the Southern Atlantic Moroccan ecosystem were analyzed using DNA barcoding and morphological reassessment. The study produced 72 unique Barcode Index Numbers (BINs) in BOLD, with nine sequences forming three new BINs, and identified potential cryptic diversity in 23 species. This dataset, created by Anas Khattab and last updated in May 2026, contributes an updated marine species checklist for Morocco.
A 317.0 KB review document authored by Wei Li, last updated in May 2026. The text systematically summarizes the natural sources, chemistry, synthetic derivatization, and biosynthetic elucidation of usnic acid and its structural derivatives.
The Australian Continuous Plankton Recorder survey provides a long-term baseline for plankton communities in Australian oceans. Data are analyzed in situ from samples captured on silk mesh, offering a concentrated view of phytoplankton cells. The project aims to map biodiversity, document climate change impacts, and support fisheries management and satellite validation.
Three 500-meter resolution GeoTIFF images provide proportional estimates of tree cover, herbaceous vegetation, and bare ground across South America for 2000-2001. The data were derived from MODIS sensor bands on NASA's Terra satellite and processed using the Vegetation Continuous Fields algorithm to represent heterogeneous land cover as continuous percentages. This product is designed to depict mixed land cover areas more effectively than traditional discrete classification schemes.
LBA-ECO ND-02 provides biomass measurements for grasses, herbs, vines, and dead material from a fertilization experiment in a Brazilian secondary-growth forest. Data were collected destructively from 12 treatment plots over six sampling events between 1999 and 2005. The experiment tested the effects of nitrogen, phosphorus, and combined fertilization on understory vegetation in 20m x 20m plots.
A 2026 figshare dataset by Davide Taurozzi characterizes diatom and plant communities in Mediterranean temporary ponds. It includes records of 89 diatom species and 52 plant species from 13 ponds across 3 areas in Central Italy. The data couples phytosociological surveys with physical and chemical measurements of water and sediments.
N2SIMBA is a simulation framework for generating synthetic 16S rDNA sequencing count tables with known microbial interaction networks. The framework, created by Matteo Baldan, uses a consumer–resource model to simulate metabolite-mediated interactions and the experimental sequencing process. The dataset was last updated on 2026-05-20 and is available as a 2.8 MB PDF under a CC-BY-4.0 license.
North-central and Northeastern U.S. environmental and meteorological drivers at 0.5-degree resolution from 850 to 2010 CE. The dataset from the PalEON Ecosystem Model Intercomparison Project (PEMIP) includes biome type, plant functional type, CO2 concentrations, land use change, nitrogen, soil data, and seven key meteorological variables. It supports high-resolution terrestrial ecosystem model simulations to study forest responses to past climatic variability.
Raw data from measurements and calculations of membrane currents under different NaCl solution configurations. The dataset, authored by Sławomir Grzegorczyn and last updated in May 2026, includes time-series data showing stable boundary layers in one configuration and current pulsations from hydrodynamic instabilities in another. Fast Fourier Transform (FFT) and Short Time Fourier Transform (STFT) analyses were applied to signals in the frequency range from 0.05 to 1 min⁻¹.
Between 29 January and 24 March 2021, zooplankton abundance and distribution data were collected aboard the R/V Investigator in the East Antarctic sector of the Southern Ocean. The dataset, from the Marine National Facility voyage IN2021_V01, supports investigations into Antarctic zooplankton community structure and ecosystem dynamics. Specimens were collected using a Rectangular Midwater Trawl (RMT 1+8) plankton net system along the Mawson coast and identified to the lowest practical taxonomic level.
GPS-imprinted landscape photographs captured at 100-meter intervals along transects in Botswana, Zambia, and South Africa. The dataset contains approximately 30 photographs per site, providing visual characterization of species composition and vegetation cover. It was produced by NASA to aid in the interpretation of other ecological data sets.
Fragmentary remains of Devonian fishes from the Knobby Sandstone formation in the eastern Canning Basin, Western Australia. The fauna includes a new species of Bothriolepis, other antiarch placoderms, and rhipidistian teeth and scales, preserved as moulds in coarse sandstone. The Australian Ocean Data Network published this description, last updated on 2026-06-04.
Rwanda is the geographic scope for this dataset comparing three fish species in mono- and polyculture systems. It contains results from a 240-day experiment conducted from March to November 2021 at the Rwasave Fish Farming and Research Station. The data, made available by author Rashidi Mwimba, includes calculations and key results from seven experimental treatments.
RNA-seq data characterizing the transcriptional responses of the marine fish pathogen Tenacibaculum maritimum to iron limitation and reduced salinity. The dataset was authored by María Pilar Escribano and last updated on May 11, 2026. It is hosted on figshare under a CC-BY-4.0 license.

It provides spatially continuous predictions of seabed %sand content in 10-meter resolution raster grids.
2016 and 2017 data on pollinator and floral resource abundance collected from 151 upland and 30 meadow plots in the Eldorado National Forest, California. The dataset was created by Gina L. Tarbill to study the effects of different burn severity classes on pollinator communities. It includes counts of bees, butterflies, hummingbirds, and flowering plants, as well as plot characteristics and geospatial information.
