Spring Bloom in Hecate	May warmth and sunshine ‘fuels’ bloom

source of imagery

After the near storm force winds of last weekend waters in Hecate again stabilizing vertically

If/ when get clear weather I will update this page

West Cost North America view

While harder to ‘recognize’ the material on this site is best for day to day imagery for Chlorophyll thus plankton bloom

While I have reduced size of image – can still clearly see the areas of bloom – especially in relatively shallow areas East of Vancouver Isl --- are in full bloom

Global view w Modis AQUA

Sunny days bring full bloom initiation

Note area marked 1 – shallow shelf between QCI and mainland beginning to go into full bloom --- the Eastern side of Vancouver Island has been in full bloom for some time – but now the western side ‘taking off’ (2) – as is the northern tip

Note too how the waters off WA (OR?) marked 3 are now in full bloom – I would predict this bloom will move north along with warmer waters

While color coding varies between imagers can read numbers --- note upwelling off OR and CA --

Correlation of SST and Chlorophyll bloom?

Most suggestive here is the light blue color coded water mass off West Coast Vancouver Island – which is the area with intensive plankton bloom(2 in image above) – And while not shown here the areas off California showing intense blooms in above imagery correlate with areas on SST graphics – in this case ‘cooler’ (relatively) upwelling areas – similar to that off Oregon in image left
