SBC LTER: Beach: CO₂ flux, wrack subsidies, invertebrate community, and consumer respiration rates for Channel Islands sandy beaches

These data result from surveys of 14 sandy beach sites on four of
California’s Channel Islands from 2016 to 2018. We quantified
marine macrophyte wrack subsidies, macroinvertebrates, beach
physical parameters, and sediment CO2 flux
at each site in order to elucidate the role of marine wrack
subsidies and wrack consumers on sandy beach sediment
CO2 flux. We also measured the respiration
rates of the six most common wrack consumer species in the
laboratory. Data are contained in two tables: 1) Mean wrack cover,
invertebrate community composition (species richness, abundance,
and biomass), beach physical parameters, and sediment
CO2 flux, and 2) respiration rates and
biomass of each replicate individual for each of the six species.
