Tara Pacific samples provenance and environmental context - version 1

This publication includes the provenance metadata and environmental context of all samples generated by the Tara Pacific Expedition. The metadata fields and parameters are detailed in the readme files. Provenance is given in a single UTF-8 encoded tab-delimited text file. Environmental context is provided in eleven UTF-8 encoded tab-delimited text files, all with the same structure, but each providing a different statistic: "n" = number of values "mean" = mean value "stdev" = standard deviation "P05" = 5 percentile, i.e. minimum (Q0) "P25" = 25 percentile, i.e. first quartile (Q1) "P50" = 50 percentile, i.e. median (Q2) "P75" = 75 percentile, i.e. third quartile (Q3) "P95" = 95 percentile, i.e. maximum (Q4) "dt" = lag in time, i.e. difference between the collection date/time of the sample and that of the environmental context provided "dxy" = lag in horizontal space, i.e. distance between the collection location of the sample and that of the environmental context provided "dz" = lag in vertical space, i.e. difference between the collection depth/altitude of the sample and that of the environmental context provided Missing value terms are: "nav" = not-available, i.e. the expected information is not given because it has not been collected or generated "npr" = not-provided, i.e. the expected information has been collected or generated but it is not given, i.e. a value may be available in a later version or may be obtained by contacting the data providers "nac" = confidential, i.e. the expected information has been collected or generated but is not available openly because of privacy concerns "nap" = not-applicable, i.e. no information is expected for this combination of parameter, environment and/or method, e.g. depth below seabed cannot be informed for a sample collected in the water or the atmosphere
