title: Validated temperature and salinity data, and reconstructed nutrient concentrations in the North Pacific (1895–2024)

description: The original hydrographic and nutrient data were compiled from the CLIVAR and Carbon Hydrographic Data Office (CCHDO; providing both hydrographic and nutrient measurements) and the World Ocean Database (WOD; supplying hydrographic data only) across the North Pacific. Rigorous quality control procedures—including range, spike, gradient, inversion, outlier checks and etc. — were applied to remove low-quality temperature, salinity, and nutrient records (NO₃⁻, NO₂⁻, DIP, and Si(OH)₄) from both databases. Three machine learning model (Random Forest (RF), Light Gradient Boosting Machine (LightGBM), and Gaussian Process Regression (GPR)) was trained on the quality-controlled CCHDO data to reconstruct nutrient concentrations, using spatial, temporal, and water mass predictors derived from the validated WOD hydrographic dataset. This process generated approximately 435 million reconstructed nutrient data points across 1.9 million stations for each nutrient species within the WOD, covering the period from 1895 to 2024 in the North Pacific (118.6 ºE to 280.3ºE; -2.0 to 60.6ºN). The final dataset offers validated temperature and salinity values along with reconstructed nutrient concentrations, providing a valuable resource for studying ocean biogeochemistry and climate-related changes in the North Pacific. In this updated version, we removed erroneous records in CCHDO to improve the foundation for model building.

This product provides reconstructed nutrient concentrations that are precisely linked to the location, depth, and time of each original hydrographic observations from the WOD. The underlying hydrographic data integrate observations from multiple platform types, including: Autonomous Pinniped Bathythermographs (APB), Conductivity Temperature Depth profilers (CTD), Drifting Buoys (DRB), Gliders (GLD), Mechanical Bathythermographs (MBT), Moored Buoys (MRB), Ocean Station Data (OSD), Profiling Floats (PFL), and Undulating Oceanographic Recorders (UOR). Nutrient concentrations are reported in umol kg⁻¹. The compressed files are named according to the reconstruction method used—RF, GPR, or LightGBM—and each contains data organized by WOD platform type.

 
description: Three compressed archives correspond to the nutrient concentrations reconstructed using the RF, LightGBM, and GPR methods, respectively. After decompression, each archive contains 20 additional compressed files. These filenames correspond to the hydrographic data and reconstructed nutrient concentrations from different platform types in the WOD.

title: Empirical Cost Analysis of Sub-Dollar Digital Payments: Comparing Legacy Fee Architectures with Byte-Denominated Simplified Payment Verification

description: Designing payment infrastructure for sub-dollar transactions requires architectures that minimise value-dependent cost overhead. This study comparatively evaluates five payment providers — PayPal, Stripe, Visa, Mastercard, and a blockchain-based Simplified Payment Verification (SPV) implementation — across 55,000 fee evaluations spanning US$0.01–5.00. A two-part cost model distinguishes fixed-plus-percentage (value-denominated) from byte-denominated fee architectures; hierarchical regression with provider-specific interaction terms quantifies the structural differences (log-level R² = 0.997). The central finding is structural: value-denominated pricing produces hyperbolic cost profiles imposing an uneconomic interval below a provider-specific threshold, whereas byte-denominated pricing yields near-zero absolute fees irrespective of transaction value. In the US$0.01–0.49 band, mean legacy effective fees range from 38.43% (Mastercard) to 237.88% (PayPal); SPV averages 0.06%. Break-even analysis shows legacy providers require US$1.42–14.29 to achieve a 5% effective fee target; SPV achieves this at US$0.002. Sensitivity analysis confirms robustness to fee multipliers (2×–10×), legacy discounts (25–50%), EU interchange caps, and transaction-size variation. Four engineering evaluation metrics — fee prediction variance, independent verifiability cost, adaptive fee response, and confirmation reliability — provide a reusable assessment framework. The results identify byte-denominated fee design as a structural solution to the micropayment cost barrier.
