Seafloor Bathymetry (meters)

Ocean depth plays an important role in the distribution and abundance of living organisms and has important implications for shipping and offshore development projects such as wind power and oil extraction. Phenomenon Mapped: Seafloor depth, bathymetry Units: Meters below sea level Cell Size: 30 arc seconds, approximately 1 km Source Type: Discrete Pixel Type: Signed integer Spatial Reference: GCS_WGS_1984 Mosaic Projection: Web Mercator Auxiliary Sphere Extent: Global oceans Source: Marine Conservation Institute (MCI) Citation: Becker JJ, Sandwell DT, Smith WHF, Braud J, Binder B, et al. (2009) Global bathymetry and elevation data at 30 arc seconds resolution: SRTM30_PLUS. Marine Geodesy 32: 355–371. Publication Date: 2009 ArcGIS Server URL: https://oceans2.arcgis.com/arcgis/ The Marine Conservation Institute used this dataset as an input to a predictive habitat model documented in the publication Global Habitat Suitability for Framework-Forming Cold-Water Corals. The source data is available from the Scripps Institution of Oceanography Satellite Geodesy Webpage. What can you do with this layer?
