Cape Ann conditions for possible Friday 8/28 AM?

[DavidInNH]

Hi folks:

I'm thinking of diving on Cape Ann on Friday morning but am wondering what the visibility is like after the storms of last weekend. Have things settled down enough to make this worthwhile? If so, I'd love to meet up with someone to dive as I'm not going to be available this weekend. Worst case, if conditions are decent, I might do Front or Back on my own. (Assuming I can zip my rear-zip suit myself.)

Thanks in advance for any information.

- Dave

not sure about up in that direction but rhode island/ct waters on monday had about 1 foot of visibility... it's the first time in a long time i've aborted a dive... it was awful...

Thanks for the info, but I may not be able to get out anyway.

We have the tropical storm approaching the coast. Large waves and heavy seas look to be upon us again at least by Saturday.

Id consult weather underground for the area and click on marine forecast.

Did Folly Cove today - vis 25-30 feet. Water temp above 60 till about 30'.
Seen many lobsters, two real lobzillas, whole bunch of strippers, single dog fish and a regular Folly's i.e moon snails, sand dollars, crabs and flounders. Everything was fine until my selenoid got stuck in an open position and I had to turn back - I did only one 68 minute dive, not even making to the mouth of the cave.

What made the solenoid stick open? Bummer. You could always goes SCR - but what a pain.

Cheers,

Thanks for the information but it looks like I'm not gonna make it this weekend anyway,

Now, what is the solenoid for? I assume you must be talking rebreather here?

I assume you must be talking rebreather here?

Your assumption is correct.

Now, what is the solenoid for?

It is an electromagnetic valve on eCCR(electronic closed circuit rebreather) that injects oxygen when partial pressure of an oxygen in the breathing loop falls below the set-point.

What made the solenoid stick open?

Have not take it apart yet, but suspect some kind of dirt, maybe rust.

You could always goes SCR - but what a pain.

Going to SCR mode is not that painful - you just vent out every 4-5 breath through your nose.
SCR mode, it is however, the wrong procedure for that kind of problem. Solenoid stuck open, means constant flow of oxygen into the loop in a rate that create hyperoxia fairly quick. (In normal circumstances, time period when solenoid is opened is given take 1sek.) If you want to vent out that much of oxygen, you will run out of gas in a no time - given that usual rebreather tank is between 13 and 19 cu ft.
The proper procedure for that situation involve opening and closing tank valve on oxygen side. It is not a difficult task - tanks on many rebreathers are reversed. You still have your sensors, pay attention to your display - when ppO2 drops, crack valve open for a second or two.
