Areas of seabed within the Heard Island and McDonald Islands Marine Reserve and adjacent Conservation Zone in one hundred metre depth ranges

The areas were calculated in ArcGIS 10.1 as follows: - 1 The bathymetric grid was classified into one hundred metre depth ranges and converted to polygons, with land excluded. - 2 The polygons were clipped to the extents of the Marine Reserve and Conservation Zone. - 3 Areas of the resultant polygon...

Description
Summary:The areas were calculated in ArcGIS 10.1 as follows: - 1 The bathymetric grid was classified into one hundred metre depth ranges and converted to polygons, with land excluded. - 2 The polygons were clipped to the extents of the Marine Reserve and Conservation Zone. - 3 Areas of the resultant polygons were calculated using a Lambert Azimuthal Equal Area projection with Central Meridian 75.594 degrees East and Latitude of Origin 51.877 degrees South. - 4 The areas were then summarised in a spreadsheet. This dataset is a spreadsheet with planimetric areas of the seabed within the Heard Island and McDonald Islands Marine Reserve and adjacent Conservation Zone. The areas are provided for one hundred metre depth ranges and are given in square kilometres. The areas were calculated for the Wildlife Conservation and Fisheries research group at the Australian Antarctic Division. Depth data was sourced from a bathymetric grid of the Kerguelen Plateau by R.J.Beaman of James Cook University, Australia and P.E.O'Brien of Geoscience Australia and published by Geoscience Australia.

The Marine Reserve and Conservation Zone boundaries were sourced from the Australian Government's Australian Marine Parks Division. See the provided URL for a link to the department's website.
