One side of the grab will be used for sediment chemistry and the other will be used for marine macroinvertebrates samples. Sediment samples will be collected and processed according to the LSASD Operating Procedure for Sediment Sampling. Marine macroinvertebrate samples will be collected at all stations. Samples will be collected utilizing a 0.04m2 Young Grab and processed according to LSASD Operating Procedure for Marine Macroinvertebrate Sampling. The sample will be sieved through a 0.5 mm screen. The remaining sample will be place in a cloth sample bag and preserved in NOTOXhisto™, non-toxic tissue preservative.
