Explosive hydrogen gas can accumulate inside the hull of 3-meter-discus buoys.
This dangerous gas is caused
by batteries corroding due to water intrusion. While a remedial
plan is being developed, mariners are asked to give
this, and all other 3-meter-discus buoys, a wide berth. The buoys are
3-meter discus shaped, typically with a yellow hull and a 5-meter
tripod mast. Each buoy is identified by the
letters "NOAA" and the station identifier number, such as
"46050". Each buoy has a group of (4) flashing 20-second,
yellow lights.
Please do not trespass, tamper
with, or tie up to any NOAA data buoy.
