They are inches. 1 inch = 2.54 centimeter

One key to interpreting this chart , at least for pond biology matters, is generally to equate reductions in clarity to plankton blooms. Note the temp changes that occur with them and the effect on DOs. Thanks Dwight for your efforts on this project.

I spent most of the afternoon on the pond this afternoon. The temps were in the low 50s and 0-4 mph winds. Pretty for November 27th.

Updated Weekly

Okay so I was one day off on my ice prediction. I'll try to do better next year. Time to sharpen the ice jigs!!!

After having record cold this year, Nov. has been above average here. First time since I built the pond ice free in Dec.
Cold coming tonight.

Looks like a very tranquil place/pond, adiriondack!

My 50 acres are almost totally bordered by Adirondack forest preserve.
After growing up in N.J. I wanted a place that no one could crowd me out of.
My wife says I'm anti-social, but I really don't hate everyone.

Any fall color pics AP ? I bet a nice reflection of fall color in the pond.

Hey Eric, didn't get good ones this year, the season went too fast.
Here's one from 2007.

Thanks AP - that is just what I expected - beautiful.

Updated Weekly

We had open water on Thursday and 2 days later we have 2 inches of clear ice. Last year on this date I believe we had around 7 inches.

It is officially winter on Bremer Pond.

That top temp can't go down much more !

The surface water temp will get down to 32 degrees as the ice goes through the transformation from warm ice to cold ice.

Interesting that the top DO is up from last week but the mid and bottom DOs have stabilized. Anyone know the saturation %s on those DOs.

If you page down toward the bottom of this link there is a chart that will answer that question.

D. O.

Neat link Dwight. Thanks.

The next "Updated Weekly" will be the winter version with ice thickness rather than clarity.

Water clarity is pretty much clear top to bottom for the duration of winter. It is difficult to get a good Secchi disk reading when ice and snow cover limit the available underwater light. I will still monitor the water clarity around the Barge for any obvious change, but the depth there is only 5-6 feet. If I can stand on the Barge and not see the bottom, I'll take reading. That probably won't happen though.

The "Updated Weekly" graph and data will remain and a new "Winter Updated Weekly" will arrive on the scene.

Happy Winter, everyone!

I don't understand the idea of warm ice and cold ice. Am I stoopid or is this something new? Isn't anyone else wondering about this, or is it a Dwight conceptual hypothisis deal that I should not worry about

Warm ice is formed when the water temperature is in the mid 30 range and is too warm to freeze. When the air temperature plunges the ice that results (up to 2-3 inches) is a low density or warm ice.

Warm ice will transform into cold ice as the water temperatures drop. During this process the ice contracts (becoming denser). Evidence of this contraction is the stress cracks that form and the attendant water flow up on top of the ice pack.

Once the ice pack has transformed ice thickness will increase at a rapid rate.

I am probably one of the few true ice observers out there that actually monitor the process week to week and document it. How weird a interest is that?

It could be weirder. You don't own a zamboni, do you?

I prefer rough ice to smooth ice, so no Zamboni here.

Are you saying that the ice next to the water is warmer than the ice exposed to air?

No, this is about the transitional period when ice first forms.

You question warrants further discussion more suited to the dead of winter. During that period ice expands and contracts due to the variance in water temperature, air temperature, and water level changes.

The ice on the water side should be warmer since it is butted up against 34 degree water, and colder on the air side butted up against the cold temperatures.

"A mind changed against it's will, is of the same opinion still"

Well, that would depend on the day, wouldn't it?
