<DIV STYLE="text-align:Left;font-size:12pt"><P STYLE="margin:0 0 11 0;"><SPAN>The carbonate percentage indicates biological material produced both in the water column by plankton and on the seafloor by a variety of benthic species that make carbonate-containing shells or other body parts. Shell debris can also influence water characteristics such as dissolved carbonate minerals, alkalinity, oxidation of solid phase sulfides, and carbonic acid production and larger grains may form the basis for several types of key biogenic habitats such as rhodolith beds, bryozoan and sponge gardens. The percent carbonate layers for the region were developed from >30,000 raw sediment sample data and compiled (Jenkins et al. 1997), then imported into ArcGIS and interpolated using Inverse Distance Weighting (Bostock et al., 2019). </SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN STYLE="font-weight:bold;">Reference:</SPAN></P><P><SPAN><SPAN>Bostock, H., C.

<DIV STYLE="text-align:Left;font-size:12pt"><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Sampling is biased against larger shell or shell fragment sizes, which are likely underrepresented in this dataset resulting in more uncertainty compared with those of mud and sand. Seafloor sediments will continually be in a state of flux due to floods, storms, earthquakes, volcanic and human activities, however these maps have been developed from a large number of samples (over 23,000) over a relatively long time frame (over 60 years), though some regions remain under-sampled and are therefore less well characterised, particularly the continental shelf regions of East Cape, southern Wairarapa, Fiordland and the west coast of the South Island (Bostock et al., 2019b). Key issues are lack of sampling data in many regions of the EEZ, and extrapolation outward from solitary point records for a large portion of the EEZ (Bostock 2019a).</SPAN></SPAN></P></DIV> |
