Ocean alkalinity enhancement (OAE) has emerged as a promising strategy to mitigate ocean acidification and reduce global warming. Traditional metal (e.g., critical materials) mining industries release alkaline waste via mining tailings with high concentrations (99.2%) of calcium and magnesium oxide (CaO, MgO). Incorporating mining waste into OAE processes is less energy in…

The Next-Generation National Household Travel Survey (NextGen NHTS) provides valuable origin-destination (OD) data for transportation analysis, but its coarse spatial resolution limits its effectiveness for detailed regional studies. In New York State, the dataset is divided into only 15 zones, restricting its ability to capture local travel patterns. To enhance spatial gr…
