These data are a time series of net primary production (NPP), growth and standing crop for
the giant kelp, Macrocystis pyrifera, that is appropriate for examining seasonal and
inter-annual patterns across multiple sites. The standing crop and loss rates of M. pyrifera are
measured monthly in permanent plots at three sites in the Santa Barbara Channel, USA. Collection
of these data began in May 2002 and is ongoing. Seasonal estimates of NPP and growth rate are
made by combining the field data with a model of kelp dynamics. The dataset includes plant
density in each plot and censuses of fronds on tagged plants at each site. NPP, mass specific
growth rate and standing crop are presented in four metrics (wet mass, dry mass, carbon mass and
nitrogen mass) to facilitate comparisons with previous studies of M. pyrifera and with NPP
measured in other ecosystems.
A subset of these data covering the time period 2002-05-01 to 2007-12-31 were contributed to
Ecological Archives as Data Paper E089-119-D1 in 2008 (citation: Andrew Rassweiler, Katie K. Arkema,
Daniel C. Reed, Richard C. Zimmerman, and Mark A. Brzezinski. 2008. Net primary production,

ABUR: Arroyo Burro: Arroyo Burro Reef depth range from 5.4m to 7.4mThere are two permanent transects: Transect 1 and Transect 2.References on land is Goleta Pier. Transects are all 40 meters in length. Eye bolts or rebar stakes mark the following distances along each transect: 0, 8, 16, 24, 32, 40 meters. Each Bolt is marked with a yellow tape flag attached with a pink cable tie. Rebar is marked with a 10-30cm piece of yellow polyethylene tubing. Eyebolts have tubing and sometimes a small float to keep the tubing upright. Concrete 1m long parking bumpers or long epoxy coated yellow rebar stakes mark the 0m and 40m of each transect. Note that the bumpers often move during storms up to 10m away!

keys and key characteristics
The giant kelp, Macrocystis pyrifera, is a brown alga in the order
Laminariales. It forms dense forests on shallow rocky reefs along the Pacific coasts of
North and South America, and along the coasts of New Zealand, southern Australia, South
Africa and the subantarctic islands (Wormersley 1954). M. pyrifera is the world?s largest
alga. An adult individual consists of a bundle of fronds (often totaling more than 100)
anchored by a common holdfast. Each frond consists of a rope-like stipe and many regularly
spaced lanceolate blades, each buoyed by a small gas bladder. New fronds originate in the
basal foliage just above the holdfast and grow vertically in the water column. Upon
reaching the sea surface, the fronds (sometimes exceeding 30 m in length) spread out to
form a dense canopy.

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.
