Thick fog hid the midnight sun for the Summer solstice, but the Green Edge team is gaining some great scientific experiences onboard the ice-breaker Amundsen.

Where is the arctic cod?
As part of the Green Edge project on the CCGS Amundsen, our team from Louis Fortier’s laboratory at Université Laval is aboard to sample zooplankton and fish. To do so, we use nets, of different dimensions and mesh size.
Cloud cover: our enemy
Most marine-optics scientists dislike cloud cover. Thick clouds hiding the water surface in the visible and near-infrared spectral region prevent them to get nice ocean color remote sensing images. Thin clouds may lead to inaccuracies in the atmospheric correction when retrieving water reflectance from the sensor, which measures top-of atmosphere reflectance. On field, cloudy skies makes it often hard to adequately retrieve some water optical properties, namely those affected by the environment, the so-called apparent optical properties. Clouds also alter the diffuse and direct sunlight making it more challenging to interpret the water, ice and snow surface reflectance. But in addition to prevent some good sciences, cloud cover also triggers some unexpected GreenEdge (mis)adventures.
