Bathymetry and substrate GIS layers

File Identifier: B5E986DB-1E8C-270D-E055-000000000001 Parent Identifier: B5EA5EF1-B521-31CF-E055-000000000001 Hierarchy Level: feature Hierarchy Level Name: Feature of Bathymetry - CMA habitat maps - bathymetry and substrate type (TR2017/34) Abstract: Habitat maps of the seabed are needed to assist in many aspects of resource management, including the assessment of high value ecological areas, designation of areas that may require protection (e.g., coastal significant natural areas) and spatial planning of human activities. Statement: The GIS data layers produced for this project include: Table With Border Layer Data type File name Bathymetry grid Raster Waikato_0.0005_NZVD2016_NZTM.grd Bathymetry contours Shapefile All_Contours_0.0005_LocalVD_NZTM.shp Bathymetry sources Shapefile BathySource_guide.shp Rocky reefs (extent and confidence score) Shapefile East and West Rockyreefs.shp Soft substrate (Folk scale and broadscale classifications) Shapefile All_subtidal_sediment_polygon.shp (N.B.

Rocky reefs also provide a habitat for significant numbers of indigenous and endemic marine flora and fauna in New Zealand (Nelson and Gordon, 1997). Many previous studies on rocky reefs have focused on local scale and community structure, with little information available on regional scale locations of rocky reef communities. The location and composition of benthic reef communities are distributed with relation to physical habitat variables, including depth, wave exposure, water clarity/sedimentation and nutrient availability (Shears and Babcock, 2000). Where possible, high resolution bathymetry, including multibeam surveys, was used to map deep and shallow rocky reefs using a slope analysis method within a geographical information system (GIS). Where high resolution data was not available, sounding sheets were used in combination with existing habitat maps and local interviews to identify areas of potential rocky reef, with a view of using this as a guide for potential future surveys.
