Team Zaaga’igan: How our research is going

This week was focused on gathering water samples from mesocosms containing wild rice and varying levels of sulfur and leaf litter for carbon. The goal is to maintain constant levels of these variables in order to study the affects of mining on wild rice. To keep up the levels of sulfur, water samples from each tank are placed in a spectrophotometer to measure the concentration of sulfur. The measured concentration is subtracted from the goal concentration in order to tell how many grams of sulfur to add to the tanks.
