These data tables contain the relationships used to estimate biomass
density from field measurements of abundance, and laboratory-derived values for
photosynthetic parameters (Pmax, alpha, and dark respiration) for 19 taxa of understory
macroalgae. Collectively, these taxa comprised 97% of the total understory macroalgal
biomass at the SBC LTER long-term kelp removal experiment sites during 2008-2011.
Biomass density is derived from either a linear relationship (adults) or average
per capita biomass (juveniles). Relationships and photosynthetic parameters can be
combined with field
data on algal abundance and irradiance to estimate net primary production for the understory
assemblage community.
These data were presented in:
Harrer, S.L., D. C. Reed, R. J. Miller and S. J. Holbrook. 2013.
Patterns and controls of the dynamics of net primary production by understory
macroalgal assemblages in giant kelp forests. Journal of Phycology, 49: 248-257. DOI: 10.1111/jpy.12023

Equations relating measures of abundance to biomass and physiological measurements
for 19 common kelp forest taxa. These data can be coupled with measures of biomass and
seafloor irradiance to estimate taxon-specific primary production along the Santa Barbara
coast.

The primary research objective of the Santa Barbara Coastal LTER is to investigate
the importance of land and ocean processes in structuring giant kelp
(Macrocystis pyrifera) forest ecosystems. As in many temperate
regions, the shallow rocky reefs in the Santa Barbara Channel, California, are dominated
by giant kelp forests. Because of their close proximity to shore, kelp forests are
influenced by physical and biological processes occurring on land as well as in the open
ocean. SBC LTER research focuses on measuring and modeling the patterns, transport, and
processing of material constituents (e.g., nutrients, carbon, sediment, organisms, and
pollutants) from terrestrial watersheds and the coastal ocean to these reefs.
Specifically, we are examining the effects of these material inputs on the primary
production of kelp, and the population dynamics, community structure, and trophic
interactions of kelp forest ecosystems.
