As part of the TReX program, I am designing a subsurface float to measure currents in the deeper waters of the Gulf of St. Lawrence. This simple float consists of a GPS and a carefully calculated amount of weight which, when deployed, will drift below the surface of the ocean for a period before jettisoning its weight and resurfacing. Upon resurfacing, the float will transmit a GPS signal, providing a point-to-point measurement of the subsurface currents in the St. Lawrence. We aim to deploy these floats in tandem with the proposed dye release experiment, helping us to understand the prevailing transport pathways and the dispersal of contaminants in the deeper waters of the region.
