Fishing Out Nutrients - Nutrient Extraction Data

<b>Overview</b>This repository contains data for the manuscript <i>'Fisheries disrupt marine nutrient cycles through biomass extraction'</i> by González Ortiz et al. (2025). The data here includes the list of sources for the nutrient composition data (List_of_Sources.csv), taxonomic information and nutrient compositions of the assessed taxa (IndustrialTaxa_NutrientContent.csv), and the extraction distribution matrices for each nutrient (NutrientExtraction_DistributionMatrices.csv). The Fisheries_NutrientExtraction_index CSV corresponds to the extraction distribution matrices and offers the identifying information for each row of the distribution matrices, including taxa, year, and marine region where it was fished. An explanation of the extraction estimates is below. <b>Extraction Estimates</b>Total catches (tonnes year⁻¹) for each species and taxonomic group caught in an EEZ or high seas region between 1960 and 2018 resulted in a dataset of over 6.7 million entries.For each entry, 100 random nutrient composition values were sampled from a normal distribution based on species/taxonomic group means and standard deviations. These values were multiplied by the total landed amount to generate 100 nutrient extraction estimates per entry.Mean extraction values for carbon (C), nitrogen (N), and phosphorus (P) were calculated, along with standard deviations and 95% confidence intervals.The full distribution matrices of extraction estimates are found as a zipped 7z folder in this repository. This zipped folder contains three CSVs, one for each nutrient (C, N, and P).The Fisheries_NutrientExtraction_index CSV file contains the identifying information for each row of the fisheries dataset which the distribution matrices are based on. Each row in the Fisheries_NutrientExtraction_index CSV corresponds to that same row in each of the nutrient extraciton distributions CSVs.The analysis was conducted in <b>R</b> and the associated code can be found at the following GitHub repository: https://github.com/FishyAdrian/Fishing_Out_Nutrients.CitationIf you use this data, please cite this Figshare repository and the original manuscript once published.ContactPlease contact <b>Adrian Gonzalez Ortiz</b> ([e-mail]) for questions regarding the data.
