Active Continental Margins Preserve Inherited Lower Crustal Structure

Data for “Active Continental Margins Preserve Inherited Lower Crustal Structure” Overview This repository contains point-to-point lower crustal density datasets associated with the manuscript: Active Continental Margins Preserve Inherited Lower Crustal Structure The datasets provide lower crustal density estimates and associated uncertainties for the Alaska, Cascadia, and Chile study regions. Two datasets are provided for Alaska based on different seismic velocity models. Files Alaska_AK112_lower_crustal_density.txt Point-to-point lower crustal density estimates for Alaska based on the AK112 velocity model used in this study. Alaska_CVM_lower_crustal_density.txt Point-to-point lower crustal density estimates for Alaska based on the Alaska Community Velocity Model (CVM) used in this study. Cascadia_lower_crustal_density.txt Point-to-point lower crustal density estimates for the Cascadia study region. Chile_lower_crustal_density.txt Point-to-point lower crustal density estimates for the Chile study region. Data Format Each file is a tab-delimited text file. Each row represents an individual spatial sampling point and contains the following columns: longitude: Longitude of the sampling point, in decimal degrees. latitude: Latitude of the sampling point, in decimal degrees. density(g/cm^3): Estimated lower crustal density, in g/cm³. uncertainty(g/cm^3): Estimated uncertainty in lower crustal density, in g/cm³. percentage(%): Density uncertainty expressed as a percentage of the estimated density. Original Seismic Data The seismic waveform data used in this study are publicly available through the NSF SAGE Data Management Center. The waveform data were accessed through FDSN web services using the MATLAB irisFetch client. The seismic networks, stations, and data selection criteria are described in the associated manuscript and Supporting Information. Lower Crustal Density Calculation The code used to calculate lower crustal density is publicly available at: https://github.com/likelymax/Lower-Crustal-Density-Calculator Details of the seismic data processing, velocity models, and lower crustal density calculations are provided in the associated manuscript. Relationship to the Manuscript These datasets contain the point-to-point lower crustal density estimates underlying the analyses and results presented in the manuscript and its Supporting Information. The summarized lower crustal density estimates are also reported in Table S1 of the Supporting Information.
