Global Kelp Timeseries from NCEAS/KEEN Working Group
This global meta-analysis documents seasonal and interannual variability in the structure of reef-based kelp dominated communities. Temporal trends in kelp biomass, stipe density, percent cover, and rates of change of kelp density are measured across various ecoregions in global temperate zones.
Data is supplied in two formats: (1) raw long table = taxon-level observations (2) aggregated table = site/date-level time series, with taxa collapsed into a focalKelp metric
