Net Primary Production (NPP) measured in benthic incubation chambers deployed at 5 sites in the Mahurangi Harbour-Kawau Bay study region. (A) The general positive relationship between Echinocardium density and NPP observed during the first summer of sampling; n = 16 replicates from each of 5 sites sampled between Dec 2006 and Feb 2007. (B) Echinocardium vs NPP with all of the data from two consecutive summers of sampling included; open symbols are replicates from the second summer of sampling. (C) Bivariate scatterplot of site averages. The remaining panels show average NPP at a site versus (D) light levels measures at the seabed, (E) the temperature of the bottom water and (F) the content of Chla in the sediment.
