As part of the Scott Base Redevelopment Marine Monitoring Programme, the impact of Scott Base's activities on the local marine environment was assessed. Sampling took place at three sites around Hut Point Peninsula on the southern half of Ross Island during October – November 2019 to assess anthropogenic contamination. Two acoustic doppler current profilers (ADCP; Nortek Signature 500) were deployed, and set with a 2-minute sampling period in 1m vertical depth bins from the seabed to the underside of the ice. Instrument heads were kept ~0.5 m beneath the under-surface. ADCP data were downloaded, extracted from their raw formats, and averaged into 10-minute intervals. A magnetic declination of 141.09° E was applied to the measured current direction to correct the readings to reflect true north and a pressure offset was applied to standardise depths relative to ambient air pressure at the seawater surface. Information on habitats and benthic epifauna assemblage composition were collected using high resolution video across 2 25m transects at ~22m depth. Multiple overlapping passes were made across the seabed transects at ~0.5 m depth contours between ~20 – 26 m in order to create a 2D orthomosaic image of each site. Analysis of the diver-collected video was done using individual frames. The video along each transect was divided into 10 equal time segments and still frames were taken at random from the first, third, fifth, seventh and ninth segments. Eight video frames were analysed per transect (i.e., n=8 per transect and n=16 per site) by one individual to minimise observer bias. Sediment samples were collected by divers to determine contaminant concentrations and sediment characteristics (sediment particle size composition, organic matter content, organic carbon content and algal pigment content) at each site. Sponge species (Sphaerotylus antarcticus and Laternula elliptica) were collected for tissue contaminant analysis.

This dataset provides river name polygons for mainland New Zealand. It is part of a pilot to understand the benefit of combining river names and location, and making these openly available through the LINZ Data Service. Unnamed rivers are also included in this dataset. **How this data can be used** Together with the [NZ River Name Lines (Pilot)](https://data.linz.govt.nz/layer/103632) dataset, these are the first openly available datasets with NZ river names attributed to geometry features (lines and polygons). This data can be used for searching for a named river and zooming to its extents, extracting geometries of a named river, creating digital cartographic products displaying river names, and analysing other features against named rivers (e.g. identifying buildings or properties within a specified distance of a particular river). **Data vintage** The river names and extents in this dataset are based on the cartographic text shown on NZ Topo50 maps as of December 2018, and are an approximation and should not be taken as official. Further details are included in the 'Naming Extents Methodology' section in the 'Lineage' of this metadata. Please refer to the [NZ River Name Lines and Polygons (Pilot) Data Dictionary](https://nz-river-names.readthedocs.io/en/latest/introduction.html) for detailed metadata and information about this dataset. **Related data** [NZ River Name Lines (Pilot)](https://data.linz.govt.nz/layer/103632) - contains smaller rivers captured as line features instead of polygons. We recommend using the two river name datasets with the following NZ Topo50 layers for connectivity and visualisation of inland hydrographic features. - [NZ Coastlines (Topo, 1:50k)](https://data.linz.govt.nz/layer/50258) - [NZ Island Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50288) - [NZ Lagoon Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50292) - [NZ Lake Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50293) - [NZ Pond Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50310) - [NZ Swamp Polygons (Topo, 1:50k)](https://data.linz.govt.nz/layer/50359) The [NZ River Name Lines and Polygons (Pilot) Data Dictionary](https://nz-river-names.readthedocs.io/en/latest/introduction.html) provides details on how to download the matching time period snapshots of this data. **Please note** - Official geographic names as listed in the [New Zealand Gazetteer of place names](https://www.linz.govt.nz/regulatory/place-names/find-place-name/new-zealand-gazetteer-place-names) must be used in all official documents as per the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008. - This pilot dataset is unlikely to be updated, however feedback will be used for future enhancements to LINZ river datasets. --- **APIs and web services** This dataset is available via ArcGIS Online and ArcGIS REST services, as well as our standard APIs.
