What kind of sunlight is available on Devon Island – and how will the greenhouse use it?
At Devon Island’s latitude on Earth, 75 degrees North , the Sun’s maximum elevation above the horizon is 38 degrees. The sun reaches its zenith in June at the summer solstice. The sun is constantly above the horizon from mid-April to mid-August and is completely below the horizon from late October until early April. The ACMG will be oriented to take maximize the available light during the field season as well as light available during a possible future extended field season. It is possible that artificial lighting may be utilized in the future to both augment existing natural light and to extend the length of the growing season.
