These data describe the abundance of macroalgal detritus (grams wet mass m-2) as part of SBCLTER's seasonal kelp forest monitoring program to track long-term patterns in species abundance and diversity. Detritus was collected in six permanent 1 m2 quadrats positioned uniformly along 40 m transects in each sampling plot. Sample collections were brought back to the laboratory, identified to species and weighed wet. The seasonal surveys were initiated in 2008 at five reef sites along the mainland coast of the Santa Barbara Channel, California, US.

The influence of choice on feeding preferences of marine herbivores
These data describe the preferences of two herbivores, the wavy turban snail Megastraea undosa and the Pacific purple urchin Strongylocentrotuts purpuratus for 14 macroalgal species relative to giant kelp Macrocystis pyrifera and the role chemical defenses play in influencing herbivory. Data cover the raw grams consumed and total phenolic content of 15 total macroalgal species found in the Santa Barbara Channel and are taken from three Santa Barbara Coastal Long Term Ecological Research sites (Mohawk Reef, Arroyo Burro Reef, and Naples Reef).

These data describe the abundance and size of reef-associated fish within permanent plots of SBCLTER's seasonal kelp forest monitoring program to track long-term patterns in species abundance and diversity. The number, size and species identity of reef fish were recorded within a 2 m wide swath centered along a 40 m long transect extending up to 2 m off the bottom. Fish size was measured as total length estimated to the nearest cm. The experiment was initiated in 2008 at five reef sites along the mainland coast of the Santa Barbara Channel.more » « less

These data describe the monthly survey on the abundance and size of fish species, as part of SBCLTER's kelp forest monitoring program to track long-term patterns in species abundance and diversity. This study began in 2000 in the Santa Barbara Channel, California, USA. The abundance and size of all taxa of resident kelp forest fish encountered along permanent transects are recorded at three reef sites (Arroyo Burro, Arroyo Quemado, Mohawk) located along the mainland coast of the Santa Barbara Channel. In these surveys, fish were counted in 40x2m benthic quadrat, and in the water parcel 0-2m off the bottom over the same area.more » « less

This dataset contains trait and elemental composition data for macroalgal samples collected across depth gradients at multiple sites in the Santa Barbara Channel, California. Each sample represents an individual specimen characterized by morphological measurements (e.g., blade thickness, stipe diameter, total height), biomass of anatomical parts (blade, stipe, holdfast, reproductive tissue), and anchoring strength. In addition, biochemical traits—including carbon (C), nitrogen (N), and hydrogen (H) content—were measured from tissue samples analyzed in the analytical laboratory. These data support a trait-based modeling approach to macroalgal community structure and distribution, contributing to our understanding of functional diversity and ecosystem dynamics in temperate marine systems. Accompanying metadata include collection site, date, time, depth, location coordinates, and substrate type, providing context for environmental variation across samples.more » « less

These data represent mean hourly values of photosynthetically active radiation (PAR) (in units of mol m-2 s-1) at five subtidal reefs and one coastal location off Santa Barbara, California. Sensors record instantaneous irradiance at one-minute or 30 second intervals, and data are averaged hourly. Sensors are mounted on the sea floor at five sites (Arroyo Quemado, Carpinteria, Naples Reef, Isla Vista, and Mohawk Reef). A surface sensor is deployed on an unobstructed coastal rooftop at the UC Santa Barbara campus; some historical observations are available from sensors mounted above the sea surface at a subset of the five sites.more » « less
