Brief description

SEAMAP is a Royal Australian Navy Research Laboratory research program designed to investigate the effects of the properties of the ocean and sea floor on acoustic propagation, noise and scattering in the waters around Australia. Experimental investigations are carried out along ocean shipping routes. The Ocean Sciences Institute (OSI) is contracted by the Maritime Systems Division of the Defence Science and Technology Organisation to collect and interpret geological and geophysical data pertinent to the SEAMAP program.

There are two main constituents in the sediments collected, microfossil remains and mineral matter. By far the most important of the microfossil remains are the calcareous ones (the foraminifera and the nanoplankton).

Lineage

Results of measurements made on the physical properties of sediment sub-samples, from cores collected on the SEAMAP cruises to the Tasman Sea and Southwest Pacific regions. Measurements were made on sediment porosity, carbonate content, specific gravity (density) and grain size.

The cores were collected during HMAS Cook cruises 6-85, 1-86, 17-86 and 12-87. A total of 120 sub-samples from 43 different gravity cores were analysed.

Purpose
The specific aims of this project are: 1. To make geophysical and geological measurements relevant to the interpretation of sea floor acoustic properties; 2. To define acoustic provinces along SEAMAP routes based upon detailed investigations; and 3. To measure sea floor topography and roughness. Use of the data is for input into geoacoustic models.
