Wet chemistry, mid-infrared spectroscopy, and near-infrared spectroscopy data collected for the kelp Ecklonia radiata in Northern New Zealand from 2019 to 2021 as described in Nepper-Davidsen et al. (submitted). All measurements were done on milled freeze dried material, and wet chemistry measurements include content of nitrogen, carbon, sulfur, ash, phenols, glucose, alginate, guluronic acid, mannuronic acid, fucose, mannose, galactose, and xylose. Data include 162 calibration samples which were sampled from 12 different sites and 12 different months and 24 validation samples.


Steps to reproduce

Calibration models for biomass profiling of E. radiata were built using partial least squares regression in PLS Toolbox (Eigenvector Research Inc.) in MATLAB, based on mid-infrared, near-infrared, and wet chemistry data. See Nepper-Davidsen et al (in press) for further details.
