MARINE & MARITIME 12ATAR

Semester Two: Schedule

Term Three Activities

Maritime History & Archaeology: Case Study - The Batavia

 

Term Four Activities

     

Marine: Environmental and Resource Management

Unit Three:

Science Understanding

  • major issues affecting Australia’s marine environment, including:

    • declining water quality
    • loss of habitat
    • over-fishing
    • introduced species
    • ocean acidification

  • types of marine pollutants, including:

    • human and domestic wastes

    • petroleum oil

    • eutrophication

    • heavy metals

  • processes used to manage and control marine pollutant problems

 

  • biosecurity is increasingly an issue of state and national concern. Introduced marine species (pests) and diseases pose a huge threat to Australia’s marine environment. Biosecurity initiatives, including the National System for the Prevention and Management of Marine Pest Incursions (the National System), aims to prevent new pests arriving, guide responses when a new pest does arrive, and minimise the spread and impact of pests already established.

Unit Four:

Science Understanding

  • strategies for managing marine biodiversity, including:

    • role of marine protected areas and zones

    • global protection of cetaceans

    • role of scientific research in marine environmental management

  • ecotourism, reasons for rules and the ethical management of human interactions with whale sharks, dolphins and whales

 

  • a world-wide sighting and photo-identification system has been created which enables people to act as citizen scientists, assisting in the conservation of whale sharks and enhancing knowledge of the demographics of this species. The demographics of whale sharks can serve as an indication of ocean health and bio-productivity. The technology, which was developed collaboratively by a multidisciplinary team of scientists, can also potentially be used to identify other marine species.

Maritime: History and Archaeology

Unit 3:

Science Understanding

  • methods of locating shipwrecks:
    • historical records
    • aerial survey
    • magnetometer
    • sonar

  • formation and decay processes associated with wreck sites (including metal corrosion)

  • underwater wreck site excavation: techniques, processing and recording, recovery of artefacts, lift bags (purpose, use and calculations)

  • conservation techniques (on-site and laboratory), including:

    • safe retrieval
    • de-concretion
    • stabilisation

 

  • in recent decades advances in science have provided new ways to locate and conserve the artefacts that are found in maritime archaeological sites.

Unit Four: 

Science Understanding

  • The Batavia shipwreck, including:
    • historical background
    • location process
    • survey
    • excavation
    • recovery
    • conservation and interpretation of artefacts.
