Southern exposures	Far end of sewage ‘outfall’
	Sun still too hot?

Compare South side and North side

Latter has much more coverage algae etc

I noticed that at seepage area on south side more life survived --- hypothesis --- Sun too hot even at lower tidal levels

(Note the occasional Fucus plant attached to Semibalanus barnacle etc)

	Compare w shaded North side
	Meter stick is at approximates same position as on South image above – but denuded area is much less on either side of stick Hypothesis: Semibalanus survives better on shaded side

	Semibalanus needed to create habitat for Fucus to attach too – and Semibalanus affected by heat
	All the little critters from North side Most hide/ live on Semibalanus More later

Much of this life is this years ‘new comers’ – presumably recently settled out from plankton	Semibalanus provides habitat & protection
