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'.

New Asterinid Seastar Species from Northwest Australia, 2008-2015

Parks Australia provides a record of a 2015 scientific publication describing new seastar species from the Kimberley region. The publication is based on four specimens collected between 2008 and 2015 and includes an updated taxonomic key. This record was migrated from the decommissioned Australian Marine Parks Science Atlas platform.

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.

NNFM with varying training size

Qing Lan from the National Institutes of Health created a dataset to test neural network performance on the forward problem of diffuse reflectance spectroscopy. The dataset records total normalized mean absolute errors across all source detector distances. For each training data percentage from 5% to 95%, the neural network was trained independently 20 times.

XGM2019e: Global Gravity Field Model with 4 km Resolution

XGM2019e is a global gravity field model represented by spheroidal harmonics up to degree/order 5399, corresponding to a spatial resolution of about 4 kilometers. It combines the satellite model GOCO06s for longer wavelengths with terrestrial gravity anomalies and data derived from satellite altimetry and topography. The model was developed by Philipp Zingerle of the Technical University of Munich.

Nutrient Loading Effects on Biogeochemistry in Three Tropical Tidal Creeks

Three field surveys in Darwin Harbour, Australia, compared water quality, sediment composition, and metabolic processes in tidal creeks under different sewage loads. Buffalo Creek, receiving the largest sewage input, showed benthic nutrient fluxes over an order of magnitude higher than the oligotrophic Reference Creek. The study, likely from the Australian Ocean Data Network, identified pelagic primary production and denitrification efficiency as key processes affected by nutrient loading.

Palynology of the Oakvale-1 Corehole: Oligocene-Miocene Pollen and Spore Assemblages

Palynological analysis of the marine Oligocene-Miocene Geera Clay and Renmark Group in the Oakvale-1 corehole, western Murray Basin, South Australia. The dataset contains diverse and well-preserved assemblages of spores, pollen, and dinoflagellates, providing fossil records for extant Australian taxa and the first Australian fossil records for some pollen types. A quantitative zonation based on major pollen taxa frequencies divides the sequence into two major zones, with the younger zone further divided into four sub-zones.

Late Cretaceous-Palaeogene Nannofossil Biostratigraphy from Challenger No. 1 Well

Late Cretaceous-Palaeogene calcareous nannofossil assemblages from the Challenger No. 1 well offshore Perth Basin revise the age of the Challenger Formation type section from Late Eocene to Middle Eocene-Oligocene. The dataset, provided by the Australian Ocean Data Network, identifies three major disconformities and shows the section is more complete than coeval sections from nearby Deep Sea Drilling Project sites. It contrasts offshore marine Palaeogene continuity with the single onshore unit, the Kings Park Formation.

Nannofossil and Planktic Foraminiferal Biostratigraphy in the Indo-Pacific

Nannofossil and planktic foraminiferal biostratigraphy data from the Australian Ocean Data Network examines the Oligocene-Miocene boundary in the Indo-Pacific region. The description suggests the dataset contains evidence on the depth-related first appearance of species like Globigerinoides quadrilobatus primordius and the co-occurrence of Globorotalia opima opima. It proposes a combined planktic foraminiferal zone N3/4 and a buffer zone for the boundary transition.
