Design is about people creating
solutions that help or improve
the lives of other people
Design is not an art although
there is art in it

Questions?
Wires not harnessed to prevent
contact with housing
Short circuit to ground created
where wire contacted housing
In summary, the detector failed because of a short-
circuit created by the abrasion of wire insulation

Systems with low herbivory (“top-down control”)
Primary production is mainly controlled by
nutrients availability
favourable climatic conditions (“bottom-up control”)
Examples
Lagoon of Venice and North Europe coastal zones
show macroalgae blooms
eutrophication
high concentrations of nutrients

Some systems have high nutrient concentrations in the water column
(Lagoon of Venice and North Europe coastal zones)
But other systems have low nutrient concentrations in the water column
(Ria Formosa)
