ETOPO1 Bathymetry Northwest Atlantic Fisheries Region (NAFO)

ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. Built from global and regional data sets. It s available in "Ice Surface" (top of Antarctica and Greenland ice sheets) and "Bedrock" (base of the icesheets). Data can be downloaded directly from the source at the NOAA website. The data is available in either grid-registered or cell-registered files in netCDF and geotiff formats. A grid extraction tool is available to download a user selected area. More details can be found in the ETOPO1 Global Relief Model Report, ETOPO1: Procedures, Data Sources and Analysis The data is presented using an aesthetic color palette (symbology) created in data processing. The official colormap associated with the ETOPO1 can be found here and an additional source can be found here. Hillshade was also processed and can be found here. Hillshade was processed in ArcGIS Pro 2.8.1 using Raster function "Hillshade", default options were applied with the only modification being a z value of 0.00001792(m), the appropriate z value for 60° Longitude. Hillshade symbology was then set to stretch using standard deviations with a value of 1, with gamma set to 1 (although 4 is the recommended value).

Please note that additional data options are available from the source and it was not feasible to prepare and present all possible data options. Please refer to the CPAWS Data Record for Elevation and Bathymetry across Newfoundland and Labrador for options. Please note that the ETOPO1 Global Relief Model is a surface that has been interpreted from best available data sources at the time of creation (2008).
