Antarctic krill reflectance measurements - Spectroradiometer data
This dataset contains reflectance spectra measurements of Antarctic krill (Euphausia superba) that were sampled from the Scotia Sea in the Southern Ocean. Reflectance measurements were made on board on freshly caught krill, using a spectroradiometer. A number of these reflectance experiments were carried out across different regions of the Scotia Sea, on male, female and juvenile krill. Reflectance measurements are given for krill in both in situ and filtered seawater, as well as for water without krill. Data are presented in terms of remote sensing reflectance (Rrs).
Funding for the work was primarily through a bursary awarded to Anna Belcher from Antarctic Science Ltd. Additionally, funding from the BAS ecosystems programme supported the project. The Natural Environment Research Council Field Spectroscopy Facility (NERC FSF) loaned the equipment required to carry out this research.

- Statement
- Reflectance measurements have been referenced to a 20 % grey Spectralon® panel (Labsphere, Inc), which had been calibrated against a reference Spectralon® panel, applying the 8°/T method used by the NERC Field Spectroscopy Facility. Data are given here for the full recorded wavelengths from 351-2450 nm. There is high variability in reflectance data < 400 nm due to the lack of light in the UV range from the light source, and so there tends to be a very low-signal to noise ratio in the region below 400 nm, and we advise caution when using data in this region of the spectrum.
