Good morning friends.  Yesterday I stayed very busy working on the computer most of the day and at 2:00 we did one sub dive with a local newspaper.  After that I raced home and got my gear ready and met a friend for a fast one hour ride and the weather was perfect, nice and overcast!  This morning it has been raining since around 4:30 and it’s still going, I am sure that won’t be good for my underwater photos today as everything flows into the sea! 
 
Here’s a sweet little Green Turtle heading up for a breath of air.  This is yet another shot from the once incredible dive spot called Vaersenbaai but as most now know Omar took care of that reef and it still hasn’t healed.  Vaersenbaai used to have this big area of turtle grass which grew in the shallows and every morning you could easily find many turtles there eating breakfast.  Sea turtles spend almost all their lives submerged but must breathe air for the oxygen needed to meet the demands of vigorous activity.  With a single explosive exhalation and rapid inhalation, sea turtles can quickly replace the air in their lungs.  The lungs permit a rapid exchange of oxygen and prevent gases from being trapped during deep dives.  Sea turtle blood can deliver oxygen efficiently to body tissues even at the pressures encountered during diving.  During routine activity green and loggerhead turtles dive for about 4 to 5 minutes and surface to breathe for 1 to 3 seconds.  Turtles can rest or sleep underwater for several hours at a time but submergence time is much shorter while diving for food or to escape predators.  Breath-holding ability is affected by activity and stress, which is why turtles quickly drown in shrimp trawlers and other fishing gear.
 
Off to work, talk to you tonight, Barry
