Hatchlings can be disorientated my artifical light at night as they emerge from the nest and crawl down the beach and swim through the nearshore waters to the open ocean currents. Depending on the intensity and wavelength of artifical, hatchlings may crawl or swim in the wrong direction, which can lead to their death.
For the past two years, Imbricata has teamed up with In-Situ Marine Optics to develop a new way to analyse low-level light data. The technology uses hemispherical photographs that capture the entire night sky. These images are converted to Hemispherical Radiance Images (HRIs) by correcting for dark offsets and applying radiometric calibration coefficients to each pixel of the raw photographs.
