On June 7, 2016, the GreenEdge team has organized many activities to showcase and explain the project, and to let kids sample and manipulate the scientific toys that they use daily. What a better way to learn than go and see for yourself?

How to assess the photosynthesis of sea-ice microalgae?
Sea-ice microalgae are unicellular organisms that can convert the solar light energy into chemical energy for producing organic matter via a complex physiological process known as photosynthesis. Continue reading Let there be light
Phytoplankton must develop deeper to access precious food
Terrestrial organisms are composed of six major elements, C, H, N, O, P, and S, in addition to more than 50 trace elements. In the ocean, nitrogen (N) and phosphorus (P) are called limiting nutrients because they may be available in concentrations which limit photosynthesis in algae. C, H, O and S typically present in abundance are therefore non-limiting. Silica (Si) is also an important resource for some algae such as diatoms that use it to form their protective shells. For growth, phytoplankton consume the available forms of these elements namely nitrate (NO3), ammonium (NH4+), phosphate (PO42-) and silicate (SiO3–) from the surrounding waters.
