Description

Bathymetry is the underwater equivalent to hypsometry or topography. Bathymetric (or hydrographic) charts are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called depth contours or isobaths).

MSP Challenge

Bathymetry is a static data layer providing general indications of water depth in a particular area.

Types

  • 0-20m
  • 20-40m
  • 40-60m
  • 60-100m
  • 100-200m
  • 200-500m
  • 500-1000m
  • >1000m

Metadata

Data Source

Emodnet bathymetry data portal.

Original Title

Mean depth full coverage.

Description

The EMODnet data products are based on the continuous average depth grid of one-sixteenth arc-minute. This grid is based on three source types: Individual bathymetric surveys, composite digital terrain data (cDTM) and Satellite-Derived Bathymetry. The latter two have been used whenever the actual survey data was unavailable for direct processing by the EMODnet partners. Whenever data were unavailable GEBCO data has been used to fill in the gaps.

Creation Date

Accessed in 2019/11

Methodology

Downloaded the (raster) data covering the interest area from emodnet. Created a composite raster file and classified it using the depth ranges of interest.

Types

  • 0 - 50 m
  • 50 - 100 m
  • 100 - 150 m
  • 150 - 200 m
  • 200 - 250 m
  • > 250 m

Original Title

Baltic Sea Bathymetry Database (BSBD)

Description

"This bathymetry layer is not based on measurements but modelled. The bathymetry is modelled based on data provided by the countries around the baltic sea. Sweden, Denmark, Finland and Estonia have all delivered data for this 500 meter grid model. The purpose of this database is to deliver a homogenous bathymetric model for the complete baltic sea at specific resolutions. It is also important to notice that this data must not be used for navigation."

Description retrieved from HELCOM\'s metadata page for this resource (2021-07-06).

Creation Date

Methodology

This layer was integrated into the MSP Challenge to show the depths in intervals of 50m depth until 250m.

Types

  • 0 m
  • 20 m
  • 40 m
