4.1 Sensors and the Collection of Physical Data

I have listed here a number of ways to monitor physical factors of ecosystems at various levels and locations. [blockquote]

  • Local monitors of all exhibit tanks to show different parameters.
    • oxygen levels of aerated vs bottom muds
    • ph change as photosynthesis changes in a green pool
    • set up a green tank highly enriched with nutrients for this
    • have a “convertible tank” where automatic changes can be introduced which then can register abiotic changes on the instruments. This provides great opportunities for schools to do research. For instance a tank may have a screen barrier separating two populations of fish or invertebrates. Oxygen, Co2 pH and other sensors monitors the whole tank. At periodic intervals, a gate is lowered seperating the water bodies of the two tanks, on the monitors, digital or graphics show a timeline and the change in physical factors contrasting the opposing sides.
    • demo of currents feeding barnacles.. ie dependence on that factors
  • Remote site monitors.
    • interactive modelling with temperature data from Race Rocks.. and implications for global change.
    • atmospheric and oceanographic sensors monitoring at Race Rocks.
    • Links and interpretations to physical measurements in real time from the Venus sub-sea research program.
    • Links and interpretations to physical measurements in real time from the Neptune sub-sea research program.
    • Links to the Victoria weather network... school contribution a part of this.[blockquote]
