Subject: RE: Orcas
Thanks to all for their thoughts!
We went ahead as planned on Sunday, calm seas, almost got too warm on 
deck. Although the orcas were still around we never saw them, however 
we were treated to 20 or 30 dolphins in the sound, presumably herded 
there by the whales.
The dive was superb, the plankton bloom of the last few weeks finally 
dying off, it was murky in the top layers, but had improved to an 
acceptable 10-15m or so below. The wreck, a 1903 steamship,is in two 
halves, the break being just forward of the boilers with a gap of 
about 10m between the two halves. We came down onto the forward 
winch, wandered aft into the holds, and onto the debris field, 
pausing at the helm to look for the compass, all we found were bits 
of it, the rest having corroded away. The bridge area has all 
collapsed onto the seabed, we are slowly working out which bit 
relates to the photograph of her, helped by the numbered portholes. 
It was clear enough to swim over to the stern section, only the 
second time we've done it, and have a better look at the break and 
the engines. The cochran boiler and two larger main boilers standing 
clear, the decking all caved in around the engine makes it look 
bigger - we must shot this section next time and spend more time just 
on this bit or the ship. 
All too soon it was time to turn and head back, over a bit of mast, 
sections of decking, and assorted bits and pieces to the forward 
section, and a quick look down in the focsle stores,  
where the spare porthole glasses, bits of navigation lights, bottles, 
spares for cargo handling all still lie.
Leaving the wreck, the tide starting to run slightly, we all kept a 
wary eye out for stray orcas - as the lowest pair of divers I felt 
very vulnerable, irrational really... but having watched them taking 
seals off the rocks 2 days earlier... I tried really hard not to 
think about it(and failed). We still managed a head on collision with 
a lions mane at the 6m stop - ouch! At a balmy 11 degrees the water 
was warm, and the time passed quickly. Its so much easier handing off 
stages when you've still got feeling in your hands - maybe I could 
manage to be a warm(er) water diver after all.
Orcas are summer transients here, they first started coming inshore 
about 5 years ago, mainly around Sumburgh head, where the big seal 
colonies are, but they are becoming more common, so we'll probably 
encounter them more often over the coming summers
