Descrição
These data describe the abundance of reef fish as part of the Santa Barbara Coastal LTER program (SBC LTER) to track long-term patterns in kelp forest reef species abundance and diversity. The study began in 2000 in the Santa Barbara Channel, California, USA, and the time series is ongoing and updated approximately annually.
Abundances of all taxa of resident kelp forest fish encountered along permanent transects are recorded at nine reef sites located along the mainland coast of the Santa Barbara Channel and at two sites on the north side of Santa Cruz Island. These sites reflect several oceanographic regimes in the channel and vary in distance from sources of terrestrial runoff. In these surveys, fish were counted in either a 40x2m benthic quadrat, or in the water parcel 0-2m off the bottom over the same area.
This dataset is formatted as a Darwin Core Archive (DwC-A, occurrence core). All taxa are counted (using an open species list), and abundances are zero-filled for each taxon not encountered. This is a derived data product and less-processed data may be available. See for more information and source data, which may include additional measurements, and for processing notes.

Descrição dos passos do método:
- One of the main strengths of the long term ecological research program is that it allows us to evaluate changes in the ecological community against the background of natural long-term variability. This long-term context is particularly important when we seek to distinguish between changes caused by natural processes and those caused by human activities. SBC LTER has undertaken long-term measurements of the abundance of reef algae, invertebrates and fish within permanent transects at 11 kelp forest sites in the Santa Barbara Channel. These data represent one of the core research activities of SBC LTER and they provide a relatively comprehensive description of community structure and dynamics of kelp forest communities within our study region.
- The number, size and species identity of reef fish are recorded within a 2 m wide swath centered along each transect extending 2 m off the bottom. See the protocol document for more information
