Te Whare Wānanga o Waitaha | University of Canterbury Senior Lecturer Leanne Morgan and Joshu Mountjoy of National Institute of Water and Atmospheric Research (NIWA) have produced a high quality map of Aotearoa New Zealand with coastal aquifers color-coded based on whether they have high, medium or low likelihood of offshore fresh groundwater. It is the first time that the likelihood of offshore fresh groundwater around the New Zealand coastline has been assessed. The results are published in the Hydrogeology Journal.
