All-sky camera system providing high temporal resolution annual time series of irradiance in the arctic
(Journal article; Peer reviewed, 2021)The ArcLight observatory provides hourly continuous time series of light regime data (intensity, spectral composition, and photoperiod) from the Arctic, Svalbard at 79° N. Until now, no complete annual time series of ... -
Development and calibration of a high dynamic range and autonomous ocean-light instrument to measure sub-surface profiles in ice-covered waters
(Journal article; Peer reviewed, 2023)The optical chain and logger (OptiCAL) is an autonomous ice-tethered observatory equipped with multiple light sensors for mapping the variation of light with depth. We describe the instrument and present an ensemble ... -
Spectral and RGB analysis of the light climate and its ecological impacts using an all-sky camera system in the Arctic
(Peer reviewed; Journal article, 2023)The ArcLight observatory provides an hourly continuous time series of all-sky images providing light climate data (intensity, spectral composition, and photoperiod) from the Arctic (Svalbard at 79°N). Until recently, no ... -
Spectral characteristics of coralline algae: a multi-instrumental approach, with emphasis on underwater hyperspectral imaging
(Journal article; Peer reviewed, 2017)Coralline algae constitute a cosmopolitan group of calcifying rhodophytes (red algae) that display characteristic optical fingerprints due to light absorption by specific light-harvesting pigments. The spectrally conspicuous ... -
Underwater hyperspectral imaging: a new tool for marine archaeology
(Journal article; Peer reviewed, 2018)By applying an underwater hyperspectral imager (UHI) to a selection of archaeological artifacts, we have found spectral signatures that are representative of materials likely to be present at wreck sites. By successfully ...
