If it happens this year for "the good stuff" it will occur for only
about 4 hours on only one day. This is what I refer to as booming.=20
Ice will make noise all the time but the booming is a very special
event and very different from just ice shifting noise.
I have chased it for 4 years now and not a lot of record time to show
for it. I have about 1/2 hour of good stuff.
My observations are only my observations and not based on anything
else. I have never seen research done on the booming event.
The event is due to happen shortly:
Look for the first night at 0F or colder.
Then hope for a full sun the next AM with rising temps.
Record from 10 AM to 3 PM during that morning.
If we get good snow before this event we are sunk and must travel to
a snow free sight.
Therefore please let me know if you see this chain of events occuring
anywhere in MN or WI. I am watching too.
When booming occures it is very loud and you will hear it for 100
yards off the lake. I find any sized deep water lake will work but I
shoot for a 1/2 mile round one by personal preference.
How to mic it is personal preference as it is not rough to capture
these sounds. I recommend that you do not cool then warm the mic a
lot. It will take it 30 mins going from a warm car to full cold
conditions to stabilize so you may hear some mic pops as it cools.
Going from cold to warm can cause condensation problems until back up
to full temperature. MD works well at very cold temps. If you use
dat you may want to put it in a cooler with a warming sports pack.
I would be happy to go attempt this with you Curt if you would like.
