San Nicolas Island benthic 1-meter quadrat counts 2014-2019
Description
These data represent counts of individuals of a suite of species counted in fixed 1-meter benthic quadrats on permanent subtidal monitoring sites around San Nicolas Island between 2014 and 2019. There are a total of nine sites, each of which has ten 1-meter square quadrats. These are the same quadrats used to asses benthic cover by point contact (see "San Nicolas Island benthic quadrat cover 1980-2019"). These counts began in 2014 and are supplemental to the counts made on 10 m x 2 m transects presented as densities in "San Nicolas Island benthic transect densities 1980-2019". The sites have usually been monitored twice per year, most often in October and April. The target species list is as follows:
Styela montereyensis
Tethya aurantia (also known as Tethya auantium and Tethya californiana)
Tealia lofotensis (also known as Urticina eques)
Cypraea spadicea (also known as Neobernaya spadicea)
Lithopoma gibberosa (also known as Pomaulax gibberosus)
Kelletia kelletii
Tegula regina
Norrisia norrisi
Sargassum horneri
