4.5.2 Introduced Species in the Marine Environment
One of the most unexpected harmful things we do to the integrity of marine ecosystems is transfer organisms around the world by ballast tanks of the Marine Shipping Industry. This article on how a mapping system might be used to combat this problem may be useful:

Other references on this website address the issues of introduced or alien species that we have to be on the lookout for affecting our coastline:

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.
