Medical information about being -300m below sea level after diving.
My job has moved me to Jordan and I have started doing some dive trips down to Aqaba from Amman. There are two routes to Aqaba:
Desert road runs along the top of the escarpment until near Aqaba and then drops probable 1000 m down to the sea. So, after the diving this not really advisable to climb back up for the 4 hr drive home. I know it is probable within safe limits, but not my real question.
Dead Sea route: From Amman, you drop from 1000 m to -250 with in a 1/2 hour of leaving Amman. The route varies from -300 m to about 200 m as you head to Aqaba. Obliviously, since the climb back to Amman is at the end this gives you extra surface time before climbing back up to 1000m.
So, the real question is: Does going below sea level give any add benefits or cause any problems?
Slow day at work, after returning from weekend dive trip.
Jason I would recommend you submit this question to DAN. I would think it would be alright, but DAN is a lot more qualified than I am on this.
My wild ass guess is that neither is a big deal.
here are the numbers:
Below sea level you will off gas slower than expected, above sea level faster . See NOAA & USN tables for further advice and info.
for myself I would plan dive time for 10 fsw deeper than actual.
i would enjoy a meal on the beach before drive home.
Bubbles peak ~ 45 minutes post dive.

Less is more.
What fugu said. Given a safe ascent from the dive and normal post-dive activities, I wouldn't give it a second thought.

I've also heard the diving in KSA is pretty good, but haven't seen many reports from there.
