http://vimeo.com/44270450 Clip from Sunday's dive on the PB4Y Privateer (Navy B24) in Lake Washington. I'm behind the camera, and this is the first halfway decent footage I've taken with the new camera worth sharing. Got some really nice lighting effects from dive buddy Dave Stucki, and Laura...

Posted this in a different thread, where it might not be seen. Thought I'd post it here: Interested mostly in DIR posters comments on doing this. Considered posting it only in the DPF forum, but its possible that not everyone has access.

#1: Not talking to your instructor Send e-mail to the instructor if they're out of town. Ask them about logistics questions, find out what their opinion is on every point in this post. Ask about how the course is going to be setup. Ask about your gear config. Ask detailed questions about...

After months and months of extensive testing on the new system including all the required Fundamentals and Rescue skills, Halcyon today announced the new H2:SPEC system. Halcyon puts its name and reputation behind this system. It truly is a revolutionary advancement over other...

2 days, 3 flat tires. Car tire LP inflator attachment would have been useful. Did a couple of C1 dives yesterday in Mayan Blue, and did a nearly 2 hour dive in Chan Hol today. The remains have been removed (or at least removed enough so that there's nothing recognizable left to the untrained...

All the models are spinning this up into a hurricane. Historically based on time of year and formation region, there's a correlation between strength (cat4/5) and how close it gets to land (USVI/BVI/Leeward Islands/Puerto Rico/Florida). If it curves it may fizzle, if it hits land it may be a...

I92L is heading somewhat in your direction, but the model predictions are pretty far out and are pretty unreliable for sub-tropical depressions. its moving fast and unlikely to develop into a tropical storm/cyclone by the time it gets to you, if it gets there. might also veer off and dump on...

BSAC appears to have infected some of the Canadians. From a forwarded e-mail from a dive shop instructor laying out their policy against using a long hose in a group with recreational divers (plus the accompanying attachment):

as of 8pm EST tonight the models are sending it directly over cozumel, 8pm monday to 8am tuesday: maximum predicted intensification right now is only 50mph (tropical storm strength). looks like you may get wet.

Mexico: 6 bodies in cave, 3 with hearts cut out CANCUN, Mexico – Police discovered six dead bodies in a cavern near the tourist resort of Cancun on Sunday, three of them cut open and their hearts removed. Authorities are investigating the identities of the four men and two women found...

I just added a post clarifying the approval rules to the sticky. I think I made it clearer that approval is primarily based on agency affiliation (UTD/GUE) with some historical exceptions.

me and my C2 buddies (dave and marcus) passed our C2 course from danny (with fred assisting) on friday. highlights: - a lot of 12-13 hour days. someone told me C2 is shorter and easier than C1 and i didn't find it that way. - my drysuit decided to become a wetsuit and i never had time to...

Any suggestions? I think mostly I just need to figure out the drysuit thing. Need to patch all the leaks and boot dip it and then i'm just worried that my 200g thinsulate will fry me in MX and might need to put together something thinner... I'm vaguely concerned about taking the drysuit...

Can someone who has taken Cave1/Cave2 recently post what the GUE procedure is for doing a gas sharing exit on the line? Its been 1.5 years since Cave 1 now (time flies) and I've forgotten the details. I know that after getting situated on the line the donator traces the long hose around from...

Apparently there are new cave 1 rule changes so that the clause about gaps only being allowed if they cross open water has been dropped and so gaps are simply allowed now (so the hotul gap is just legal now). And restrictions are allowed now, what is not allowed is 'restricted passages'. So if...

NHC advisory on newly formed TD1:

Scientists Fear People Spread New Swine Flu - WSJ.com CDC is not issuing any travel advisories, and it sounds contained to Mexico city and doesn't affect the Yucatan or anywhere like that, but this probably bears some watching... This isn't related to avian flu (H5N1) EDIT -- looks like this...

from: Wunder Blog : Weather Underground "By Friday, as Gustav approaches the Cayman Islands, the storm will be underneath an upper level anticyclone, and over the highest heat content waters of the Atlantic. The HWRF and GFDL models respond by intensifying Gustav to a Category 3 hurricane...
