Story: Charting the sea floor

Bathymetric chart, 1960

Bathymetric chart, 1960

This portion of a New Zealand Oceanographic Institute chart is derived from the work of oceanographers Jim Brodie and Henry Pantin. The bathymetry was determined by New Zealand Oceanographic Institute soundings and from admiralty records. Before the days of multibeam echo sounders, charts gave only a vague impression of the shape of the sea floor.
