We present Jingwei-Nutrients, a global monthly data product of ocean nitrate, phosphate, and silicate from 1965 to 2023 down to 2000 meters. Built using a multi-task deep learning framework, it combines sparse historical observations with hydrographic information. This continuous record helps scientists understand marine ecosystems and climate change responses. We also provide the Jingwei web platform (https://jingwei.acemap.info) for dynamic data exploration and visualization without coding.
