Another close up of sewer outfall	Are all those dead barnacles found up here too?
	(yes)

Had to go back and look again – now that I am seeing that many juvenile barnacle ‘shells’ are ‘empty’ thus dead ---

It seems doubtful that ‘heat’ is killing them – the hot days happened when tide in during hottest

So I went higher up on outfall to see if story the same – it was

	A reference point
	This is approximately the blue arrow in previous fig

	Site 1
	Yes almost all the lighter coloured barnacle species are dead for example: D

Site 2

For whatever reason this is a richer area than previous ‘close-ups’—note Fucus juveniles. limpet juveniles and periwinkles

The light colored juvenile appears mostly dead while the greyish juvenile is only occasionally – example D

	Another rich area

Previous Sewer Outfall:

1--May overview of Outfall project

2—May attempt to monitor South side but new critters too small to ID

3—look at lower end w ‘seepage’ N vs S

4—earlier where 1^st see North has different spp than South

‘Lower South Side: ’yellow arrow and blue arrows

Lighter juvenile barnacles as Semibalanus

Before I had seen the wavy lines of Atypical and thought the juveniles were Balanus glandula --- but this image shows the wavy line is seen in adult when ‘beak’ relaxes from ‘Typical’ position—see my previous for differences B gladula, Semibalnus and Chthalmus
