Quadrat: more than just a square frame!
Just as its name implies, a quadrat is a square frame. Despite its simplicity, the imaged quadrat plays a fundamental role in my research about modern traces of life-substrate interactions. In fact, I place the quadrat on the seafloor and then the traces within that quadrat are identified, photographed and counted.
This will allow me to produce maps of bioturbation (sediment reworking)!
