We often get queries on different aspects of the AUSMAP sampling approach. Here is a quick tip to help with your next microplastic survey.
WHERE DO I EXACTLY SET UP MY TRANSECT?
In order to carry out an effective microplastic survey, you need to select the most appropriate strandline for your transect.
A strandline is the line/s on a shoreline where the last high tide has deposited debris. Of course in non-tidal environments there is not always a strandline and we generally sample along the water's edge (more details on this in a future tip).
First, look for an obvious line of dampness or an area, where seaweed has accumulated.
If there are several strandlines, choose the one with the highest amount of debris present.
If the strandline has been disturbed, select the next lowest strandline towards the shore.
And remember it’s always best to sample after the highest tide of the month or a storm event.
