FIGURE Major revision and merger with NOAA Working Diving Standards and Safety Manual approved by NOAA Diving Control and Safety. Board. The NOAA Diving Manual is a comprehensive reference specifically designed for the diving professional. It was originally written for use by NOAA divers to.

Assuming that's a typo for "spendy"? Bear in mind that right now Congress and Trump are playing the sadly usual annual budget piss-fight games, and many things are shut down. Personally, I think we'd all do better if Congress had the audacity to pass a bill saying the first things to shut down and go unpaid were the White House and Congressional staff and salaries--including all of the elected persons, and all of the staff, including gate security. And that had to happen 30 days before the rest of the budget ran out. Give 'em some incentive on both sides.
