nwgeogirl  > The Beautiful Briny Sea > Sund Rock - Low Dissolved Oxygen
September 2006 - Hood Canal is having its annual low oxygen event, but it appears to be even worse than previous years. Many critters were stressed, many were already dead. The invasive tunicate, Ciona savignyi, has taken a firm foothold in this location now. We did two dives at Sund Rock, and here is what we found.

nwgeogirl > On our second dive at Sund Rock, proper, we found many Wolf Eel, extremely lethargic, struggling to breathe, and up in very shallow waters. We had several sightings in only 15 feet of water. Wolf Eel usually inhabit areas around 60 feet or deeper.
nwgeogirl > Ciona savignyi, one of three species of invasive tunicates that Washington state is currently attempting to deal with, is now clearly taking a foothold on Sund Rock. Previously not sighted there, it's starting to appear in clusters in the 40-50 foot range.
nwgeogirl > Another critter in distresse were Sunflower Stars. These large sea stars usually are found all over. We found not nearly as many this time, and some of the ones we found were clearly dying - shriveling up, turning whitish gray. This one was in 60 feet of water.
nwgeogirl > It was very sad to see several Sailfin Sculpin dead in the shallows. These are usually a big highlight for divers to see.
nwgeogirl > Another Wolf Eel in only 20 feet of water, resting out in the open. If you see these critters during this low oxygen event, please do NOT disturb them or attempt to play with them. They are struggling to survive, and provoking them to move is using up precious energy and oxygen.
nwgeogirl > On our way in from the second dive, we found many more ling cod washing up on the beach.
