The northern Lake Huron Buoy is about 200 yards off the wreck of the Monrovia in 170ft of water 16 miles off shore. The lower mid lake Buoy is in 240ft of water some 25 miles offshore off of Yankee Reef.Guest wrote: ↑October 23, 2022, 3:38 pm How deep is the water where these wave buoys are located and how far from shore are they?
Do all great lakes have them?
Thank you in advance.

Re: wave height buoys
I think the map below shows the location of most buoys on the Great Lakes that measure and report wave heights. If you zoom in at particular locations you can see nearby water depths.Guest wrote: ↑October 23, 2022, 3:38 pm How deep is the water where these wave buoys are located and how far from shore are they?

N/A means no current data is currently available from that buoy. Many have probably already been removed from the Lakes for the season since ice will damage or move them.

Re: wave height buoys
If you are wondering how buoys measure wave heights, they use electrical sensors called accelerometers. They measure the vertical acceleration of the buoy. And if you ever took a calculus class, you may recall that if you integrate acceleration once, you get velocity, and if you double integrate it you get distance. So the sensor, combined with a small computer chip that integrates its signal will tell the buoy's data acquisition system how far it moves vertically on each wave.srh7934 wrote: ↑October 20, 2022, 9:01 pm How can you mesure wave hights
Re: wave height buoys
want to buy a "used"" wave height bouy?? i believe MRC in port colborne has 1 available.
Re: wave height buoys
NOAA, the University of Michigan - Engineering and NDBC, have buoys that measure wave heights. If you click on the buoys, it says "significant wave heights", but if you click "current conditions", it shows it as "wave heights" - but the values are the same. You can always send an email to the webmaster at https://www.ndbc.noaa.gov/ and ask if they are measured wave heights or significant wave heights.
Other buoys that you find are deployed in the Summer - they are for measuring wind speeds, pressure - for studies, such as meteotsunamis on Lake Michigan, as an example.
The website Seagull has a very nice interactive page where you can select buoys, set them as favourites, and compare wave heights, wind speeds, etc to other buoys. I like to look at the observations and use them as ground truth in meteorology - that is to verify numerical weather prediction model output that I use and/or generate. https://seagull.glos.org/data-console
BTW, buoy 45004 (East Lake Superior) had a peak "significant wave height" of 15.75 feet, while SPOT-1362 (Munising) had a peak "significant wave height" of 16.75 feet.

wave height buoys
At one time the buoys operated by NOAA and the National Data Buoy Center would indicate “Significant Wave Height” in the area where they are deployed. Now very few indicate wave height. Are there any buoys on the lake other than these that can indicate wave height?
