Approximately a one-arc degree square region in the Northeast Atlantic Ocean

Bathymetry and Elevation

Multi-beam echosounders

This data set consists of a bathymetric grid derived from multibeam bathymetry data from cruise JC071. The bathymetric grid was created by gridding the cleaned raw multibeam data from JC071 at 1/64 arc-minute intervals using a nearneighbour gridding algorithm from the Generic Mapping Tools (GMT) software system. The data set covers an approximate one degree square with the minimum and maximum longitude and latitude co-ordinates: 17.016667W-16.216667W; 48.78333N-49.28333N. This is located in the Northeast Atlantic Ocean area. The data were collected from 7th-8th May 2012 using an EM120 Multibeam Echo-sounder. The cruise was part of the Porcupine Abyssal Plain (PAP): sustained ocean observation project. The bathymetry data were collected on an opportunistic basis during the cruise. The cruise was operated by the National Oceanography Centre (NOC), equipment operated by National Marine Facilities Sea Systems. The bathymetric grid was created by BODC for contributing to the EMODnet High Resolution Seafloor Mapping (HRSM) Project.
