Spring Bloom	Skeena R runoff?

Good satellite picture allows us to follow the course of spring in Hecate--- note how yellow surrounds Haida Gwaii (QCIs) – the red color in Dixon Entrance suggests to me that the Skeena River run-off water is providing the nutrients for bloom and the Sunny weather is ‘gobbling’ it up and turning those nutrients into algal biomass

Earlier views

May 13^th using ‘dandelions’ as indicator

May 10^th where guess SST and bloom related

Dixon Entrance in full bloom

Bigger Picture

Earlier I had suggested that the > SST (Sea Surface Temperature) helped explain the bloom and that our area would bloom as SST increased --- From perspective these images looks like that was not true (the 8°C is in bloom not the 9°C)

On image left the SST does correlate with bloom areas in California—only there it is cooler water (upwelling—thus ‘new’ nutrients) that is involved

		SST or ??
		Here looks like warmer/ shallower waters off QCI bloomed 1^st (May 12^th) and then in decline by 21^st while deeper waters in Hecate and all Dixon Entrance in bloom by 21^st

		Coastal perspective
		Comparing west cost view – here looks like area off West Coast Vancouver Island (WCVI) in full bloom on 12^th and in (relative) decline by 21^st
