资源简介：
These data describe 1987-2019 time series of giant kelp
( Macrocystis pyrifera ) biomass and associated
environmental variables (wave height, nitrate concentration, climate
indices) at quarterly and annual time intervals. Data for spatially
resolvable variables (giant kelp biomass, wave height, nitrate
concentration) pertain to 361 coastline segments (500 m length) in
southern and central California where giant kelp was persistent over
the sampling period. Data are contained in 5 tables: 1) quarterly
time series of giant kelp biomass, wave height, and nitrate
concentrations for 361 coastline segments; 2) quarterly time series
of aspatial climate indices (NPGO, MEI, PDO); 3) annual time series
of giant kelp biomass, wave height, and nitrate concentrations for
361 coastline segments; 4) annual time series of aspatial climate
indices (NPGO, MEI, PDO); 5) locations (latitude and longitude of
center) of coastline segments. Kelp data are derived from satellite
imagery using empirical relationships. Wave data are derived from an
empirically validated swell propagation model. Nitrate data are
derived from empirical relationships with remotely-sensed sea
surface temperature.
