Looks like most the rain to southern BC

Monthly Summaries



Interesting series with 2004 and 2005 blooms furthest along 2008 images degrading for offshore BC -- Monthly images source

Note offshore northern California in 2005 least bloom in series Bloom 4/2004 already into Dixon Entrance

SST Anomalies



2008 coolest SST in series ----- 2006 through 2008 progressively cooler Source of images w archives
	2005 El Nino year Last week of April was warmest in series (presumably) since previous El Nino 1997-98 But I would suggest 2004 bloom was ‘earlier’ than 2005 based upon ‘Monthly Summary’ –

Serendipitously I have the April 2004 bloom in Hecate already done

Presumably the bloom peaked on 20^th

And began on 12^th --- Images suggest the 2002 bloom was even sooner – peakig on the 16^th (but have to be sceptical of different image source

Previous Blooms on this site

I looked at last week March bloom over the years a few weeks ago ---

See Hecate bloom in 2004

Hecate in Bloom 2005

And this one for lots links to previous blooms

Bloom 2006 --- and Hecate in 2007 April bloom

Questions

One of ‘problems’ in changing climates is that some species will ‘miss’ the main bloom if it comes early or late --- the series here shows wide range of SSTs – but looks like bloom sequence relatively impervious to SST (using the ‘monthly’ data (responding to increased daylight etc??)-

Needs to be looked at more critically

Especially comparing 2004 and 2005 daily/ weekly data: Hecate bloom in 2004 Hecate in Bloom 2005
