Summary:
The increasing use of hyperspectral optical data in oceanography, both in situ and via remote sensing, holds the potential to significantly advance characterization of marine ecology and biogeochemistry because, in principle, it can provide much more detailed inferences of ecosystem properties via inversion. This study focuses on complementary approaches to quantify the degrees of freedom in hyperspectral measurements in the case of in situ particulate absorption measurements, though these approaches can also be used on other such data, e.g., ocean colour remote sensing.
