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.
3 Date The ordered nominal date on which the data was collected at a specific site.
4 Species The unordered nominal species ID number. This number denotes a discrete taxonomic level being sampled. It may refer to a group of taxonomically related organisms (E.g. "Miscellaneous Invertebrates" or "Porifera"). More often, it refers to a discrete species (E.g. "Balanophyllia elegans"). This ID number can also refer to the type of substrate under each point per replicate (i.e. "Rock", "Cobble" or "Sand"). The type of substrate under each point is always recorded.
5 Replicates The number of replicates conducted for each random point contact transect at a specific site in a specific year.
6 PointsPerReplicate The number of random points sampled on each replicate of a random point contact transect.
7 CoverMean The continuous numeric mean percent cover of each species at a specific site in a specific year.
8 CoverSE The continuous numeric standard error of the percent cover of each species at a specific site in a specific year, calculated across replicates.
