This buoy is located in Gray's Reef National Marine Sanctuary The southern third of NOAA's 22-square mile Gray's Reef National Marine Sanctuary has been designated a research area specifically designed for conducting controlled scientific studies where human activities cannot affect the results. Fishing and diving will be prohibited in the lightly used, 8-square mile research area. Vessels are permitted to travel through it without stopping. For complete information, go to the Gray's Reef website at Gray's Reef Research Area LINK TO PMEL's pCO2 SITE for their data on this Station:

http://www.pmel.noaa.gov/co2/story/Grays+ReefRight whales are active off GA from November to April. Speed restrictions of 10 knots apply to vessels 65 feet or greater within the vicinity of this station between November 15 and April 15. It is illegal to approach right whales within 500 yards. To learn more about right whales and rules protecting them, go to: http://www.nmfs.noaa.gov/pr/shipstrike.

Questions about buoy 41008

Where is buoy 41008?

NDBC station 41008 is moored at 31.400°N, 80.866°W — GRAYS REEF - 40 NM Southeast of Savannah, GA, in 16 m of water. The closest other reporting station is Marsh Island, Sapelo Island Reserve, GA (SAXG1), 22 nm to the W.

How big are the waves at the Grays Reef buoy right now?

As of the Aug 27, 10:30 PM EDT report, 41008 shows 2.0 ft significant wave height on a 5-second dominant period from the SE. Over the past 46 days, 56% of readings were under 2 ft and the biggest day reached 5.2 ft.

How windy is it at Grays Reef buoy 41008?

Wind at 41008 is 11.7 knots from the SW, gusting 17.5. The strongest gust in the past 46 days was 41 knots.

Why are some fields blank?

Waves are sampled every 30 minutes and pressure tendency is computed hourly, so most 10-minute rows carry no value for them. NDBC prints “-” (or “MM” in the raw feed). A field that stays blank for days usually means a sensor fault; NDBC lists outages on its station status page.
