Table 1 Summary of long-term means (and range) of sea temperature and nutrient concentrations (nitrate and phosphate) at the sampling sites (Table S1). Average C:N ratios for kelp tissue collected in spring and summer from each region. Light, current and nutrient data were obtained from BioOracle and averaged over 2000-2014.
From: Smaller plants in warmer water could have implications for future Kelp forests
