SBC LTER: Santa Cruz Island: Cover of Algae, Invertebrates and Benthic Substrate
These data describe the cover of benthic substrate as determined by a random point contact method. The presence of algae and invertebrate species as well as abiotic substrates are recorded at 80 randomly spaced points along 40 m x 2 m transects. Only one substrate type is recorded at a given point. Percent cover of a given substrate on a transect can be estimated from RPC observations as the fraction of total points at which that substrate was present x 100. These data are part of a long term investigation of temporal patterns in reef community composition. The sampling locations in this dataset include eleven sites along the north shore of Santa Cruz Island. Data collection began in 1982 and this dataset is updated annually.
SBC LTER: Santa Cruz Island: Abundance of Surfperch and Garibaldi
These data describe the abundance and age structure of select fish species at 11 sites on the North coast of Santa Cruz Island. The study was initiated in 1982, in the Santa Barbara Channel, California, USA, and this dataset is updated annually. The abundance and age structure of all Black, Striped, Pile and Rubberlip Surfperch as well as Garibaldi encountered are recorded at permanent transects in three depth strata at at each of 11 sites. In these surveys, fish are counted along a 40m x 2m transect, counting all individuals in the water column and in the understory algae.
SBC LTER: Santa Cruz Island: Abundance of Pycnopodia helianthoides
The purpose of the Pycnopodia sampling is to determine the relative abundance of the species Pycnopodia helianthoides at each of 11 sites along the north coast of Santa Cruz Island. P. helianthoides can be an important predator in rocky reef systems and has been thought to contribute to community phase shifts on Santa Cruz Island. Divers conducting fish count in 2003 observed a rapid increase in P. helianthoides individuals and began counting this species during routine surveys.
SBC LTER: Santa Cruz Island: Abundance and Biomass of Benthic Organisms (food resource collection)
These data describe the abundance of benthic organisms as determined by random quadrat scrapings. These data represent the availability of food resources for fish at various depths, and are part of a long term investigation of temporal patterns in reef community composition. The sampling locations in this dataset include three sites along the north shore of Santa Cruz Island. Data collection began in 1982 and this dataset is updated annually.
SBC LTER: Santa Cruz Island: Abundance of giant Kelp (Macrocystis pyrifera)
These data describe the abundance of giant kelp, Macrocystis pyrifera, at Santa Cruz Island (north shore), Santa Barbara Channel, California. The number of Macrocystis fronds were recorded along permanent transects at 11 sites, and sampling is designed to complement both the SBC LTER Reef Kelp Forest Community Survey study and other long-term data from Santa Cruz Island. Sampling began in 2011, and this dataset is updated annually.
SBC LTER: Santa Cruz Island: Aggregated mean abundance of black surfperch (Embiotoca jacksoni) and prey availability, 1994-2008
These data are the annual mean abundances of three age-classes of black surfperch and their prey at each of 11 sites at Santa Cruz Island, California. Reported values are a) the average number of adult black surfperch, young-of-year black surfperch, and one year-old black surfperch per 40m x 2m transect (for all transects), and b) total food availability (grams per 0.1 m squared) at each site. Food availability includes biomass of caprellid and gammarid amphipods and is calculated from the mean density within Gelidium spp. (for caprellids) and all other foliose or turfing algae (for gammarids). The data also include one year lags for each variable, i.e. the value of the variable at that site in the previous year.
Records of moored SeaFET pH, SeaBird CTD and oxygen at Anacapa, Santa Cruz and San Miguel Islands, California from 2012-2015
Data are pH (total scale, SeaFET), salinity, conductivity, temperature, depth (Seabird 37 CTD) and Oxygen (MicroCAT C-T-ODO) from instruments moored at three sites along the north shores of the northern Santa Barbara Channel Islands, California, USA. At Anacapa Island (ALC), in a marine reserve with kelp forest habitat; at Santa Cruz Island (PRZ), surrounded by a large shallow eelgrass bed (Zostera pacifica); and at San Miguel Island (SMN), in open water over a sandy bottom. pH sensors were deployed at all three sites in 2012, with CTD and Oxyten senosrs added to moorings at ALC and PRZ in May 2013. Benchmark samples for SeaFET sensors calibration were collected 1 to 8 times during each 2 - 3 month deployment via SCUBA, free diving or from a pier with a GO-FLOW (General Oceanics) bottle (see methods). Oxygen data were validated by Winkler titations, with concentrations reported in various units and as saturation. Data are presented in: Kapsenberg, L. and G. E. Hofmann 2016. Ocean pH time-series and drivers of variability along the northern Channel Islands, California, USA. Limnology and Oceanography. 61: 953-968. DOI: 101002/lno.10264.
