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 whether the density refers to a particular lifecycle stage of the Giant kelp, Macrocystis pyrifera or to the density of that species' fronds.
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 of each measurement of kelp density per square meter at a specific site in a specific year.
8 DensitySE The continuous numeric standard error of each measurement of kelp density per square meter at a specific site in a specific year, calculated across the replicates.
