Column_Number Column_Header Column_Description
1 Site The unordered nominal specific ID number of each discrete sampling site.
2 Year The ordered nominal year in which the data was collected at a specific site.
4 Date The ordered nominal date on which the data was collected at a specific site.
3 Species The unordered nominal species ID number. This number denotes a discrete taxonomic species (E.g. "Tethya aurantia" or "Haliotis rufescens"). More finely, this ID number may refer to a particular lifecycle stage or size class of a discrete species (E.g. Giant kelp, Macrocystis pyrifera, is broken into size and age classes "Giant kelp, juvenile (less than 1m in height)").
5 Replicates The number of replicates sampled at a specific site in a specific year.
6 AreaPerReplicate The area sampled for each replicate in square meters.
7 DensityMean The continuous numeric mean density of each species per square meter at a specific site in a specific year.
8 DensitySE The continuous numeric standard error of the density or each species per square meter at a specific site in a specific year, calculated across replicates.
