Benthic Reflectance Maps for Coral Sea Atolls from Sentinel-2 and Bathymetry

A 2026 code repository and dataset from the Australian Ocean Data Network details a method for estimating seafloor reflectance up to 50-60 meters deep using Sentinel-2 satellite imagery and bathymetry data. The dataset includes case studies for three reef complexes in the Coral Sea and part of the Great Barrier Reef, assessing the method's sensitivity to input data quality. It processes the first four spectral bands of Sentinel-2 imagery to evaluate their effectiveness for deep-water benthic mapping.

Latex Balloon Degradation in Freshwater, Saltwater, and Compost Over 16 Weeks

A 16-week study quantified the degradation of latex balloons in saltwater, freshwater, and industrial compost environments. Bi-weekly measurements tracked changes in mass, ultimate tensile strength, and surficial composition via ATR-FTIR spectroscopy. The data, hosted by the Australian Ocean Data Network, compares two balloon colors and packaging labeled as 'biodegradable' versus 'traditional'.

PAH Emission Spectra: Dependence on Starlight and Dust Properties

B. T. Draine and collaborators at Princeton University provide emission spectra from their 2021 paper on polycyclic aromatic hydrocarbon (PAH) excitation. The dataset includes spectra for 14 different radiation fields, including modified MMP, BC03 and BPASS stellar population models, and an M31 bulge spectrum. These spectra are used to calculate dust grain heating and resulting infrared emission for selected values of the intensity scaling parameter U.

Human Anterior Temporal Lobe Recordings of Ripple Oscillations and Spiking Activity

Direct brain recordings from the human temporal cortex include intracranial EEG (iEEG), local field potential (LFP), and single unit activity. The data, from the National Institutes of Health, demonstrate that 80–120 Hz ripple oscillations contribute to broadband high-frequency activity and reflect underlying neuronal spiking synchrony.

Great Lakes Connecting Channels Water and Sediment Quality

Environment and Climate Change Canada collects water quality and suspended sediment data from five connecting channels of the Great Lakes: the St. Marys, St. Clair, Detroit, Niagara, and St. Lawrence Rivers. This monitoring establishes baseline status, tracks long-term trends, and assesses the effectiveness of management actions and compliance with sediment quality objectives. The dataset focuses on the unique hydrological system where these channels originate from the outflow of large, oligotrophic lakes.
