Data and code for "Polar amplification and subtropical decline of net community production in world oceans"

This repository contains the core data and R scripts used to reproduce the analyses and figures for the study on global ocean net community production (NCP) from 2003 to 2022. The 'data' and 'data2' folders contain the same datasets in different formats: 'data' is for R users (.RData and .fst), whereas 'data2' is for non-R users (.nc and .csv). Please do not cite this dataset directly. If you use these data, please cite the original article associated with this Zenodo record. ncp_env_ml.RData: Input data for machine-learning model analyses. Monthly NCP (ncp) is in mmol O2 m-2 d-1. ncp_climate_ym_20.RData: Monthly gridded NCP and environmental predictors for 2003–2022.
