July’s SSTs	Still cool off BC
	BUT – see anomalies: Bering & CA-OR

---

Bering Hot—NE Pacific cool

(2007 anomaly)


20C contour similar – but 15C large variation w 2004 just off southern QCIs


Note 15C contour varies off WA-OR coast (green arrow) with 2001 & 2006 ‘coolest’ – this is an area where ‘dead zones’ began showing up around 2000

--	Consequences??
	The anomalously warm Bering Straits is most worrisome – but locally the warming off SE AK (arrow) suggests we should be seeing changes off our coast too

Consequences of cool Pacific on Skeena River

Cool Pacific in 2007 -à late snow melt upriver

Heavy snowfalls upriver in May and cool spring have made the snow melt later than usual—(figure left compares 2006 & 2007) --- and below shows more detail for 2007 –Note high levels since June with the last 3 weeks in July (into August) at (or exceeding) record heights

Graphs from Env Canada river monitoring site

May SSTs ---and seasonal SST changes in ‘spring’

June SSTs w similar format to above

See my 2006 SST articles where series in seasons not all one month

See also the 2005 PDO article where concept flips from one steady state to another --- suspect as ‘Global Warming explanatory concept’ now being used

Time will tell – effects on salmon etc

Since about 2000 ‘we’ are into new territory --- where immediate past (last century) may not be a guide to what to expect – be it salmon migrations or marine productivity --- or even Skeena river discharge
