KN145L4: Perth Canyon Seafloor Bathymetry Survey, 1994

A 1994 bathymetry survey of the Perth Canyon off Australia was conducted by the Woods Hole Oceanographic Institution's R/V Knorr using a SeaBeam 2112 sonar system. The dataset contains 128-210 meter resolution, 32-bit geotiffs processed with CARIS HIPS and SIPS software. Appropriate acknowledgment must be given to Dr. G. M. Purdy and the Marine Geoscience Data System.

Use Cases

• Modeling submarine canyon topography based on bathymetric survey data.
• Analyzing seafloor geomorphology based on high-resolution sonar mapping.
• Studying geological features of the Perth Canyon based on processed geotiff data.

Strengths

• Data originates from a specific, high-precision survey (KN145L4) conducted by the Woods Hole Oceanographic Institution.
• Bathymetric data has a defined resolution range of 128-210 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias inherent to a single survey conducted in November 1994.
