JC-it's Jeremy, we met in Trempealeau, WI at Lock #6, I'm finally working my way thru the day to day postings and thoroughly enjoying it. Then I saw your photo of the YSI buoy and your question about what is this thing...I recognized the name since I'm a hydrogeologist / environmental consultant and we use YSI products for other applications. Bottom line is this is some remote deployment of a sensor, can collect data on elevation of water, collect water quality samples from specific depth horizons..etc..and the deployers can get the data in real time via telemetry. Here is some info for what I believe is the model EMM68 Buoy :

A quickly deployable water monitoring platform with remote telemetry.

Just two people needed to lift this buoy into place reducing deployment and maintenance costs. The entire system can be installed without divers, allowing for complete serviceability from a small boat or watercraft. A buoy that is secure and difficult to steal or vandalize.

Collect data from any YSI 6-series or EXO sonde via two data delivery systems.

Receive remote data via two data delivery systems:

• Basic data delivery sends a raw data file to your computer

• Web-based option posts data directly to a public or private web site.

Among the advantages of remote data delivery are:

• Save you unnecessary trips into the field, reducing operating costs

• Makes you aware of changing conditions as they occur, improving response time

• Match your calibration and maintenance schedules to actual sensor performance, reducing consumables

Collect data in waters that may have been previously out of reach. The EMM68 buoy is an economical alternative to an installed permanent fixture on bridge pilings and piers.

Applications Include:

Dredge Monitoring

Baseline studies

Dye-tracing studies

Emergency response

Fisheries

Industrial sites

Non-point source/TMDL

Point source/discharge

Stormwater & CSO

Source Water

University/research

Wow great info! Thanks for sharing! And I’m glad you’re enjoying the posts.

Day 5 feels like a dim memory haha, but I do remember that buoy! I wonder if it was water quality related. Seems like it was definitely remote delivery due to the solar panel.

Very cool, and good to hear from you Jeremy!

I'm enjoying your story of your trip down the "River". Hope to meet you when you get to the lower River. I'm inland at lower river mm 839 and can meet with any supplies if needed. Mike

I believe that the Mississippi River is so majestic she deserves to be capitalized in all circumstances ! :)

And sounds good Mike, I’ll definitely be in touch!

The Loons are wonderful. I’m guessing that’s where the term “looning about” comes from?

Hmm I haven’t heard that one before, but it’s possible! Is it a British expression?

That loon video…😍. Love your descriptions and appreciation of every inch of the river. Star Island sounds divine. Wanted to stay there in 2020 but my paddling friend was on a schedule. Glad you are taking time to savor it.

Astonishing video of the loons!!! They were definitely talking to you, weren’t they? And with the mist? Other-worldly.

These first few days I’m finding very moving - thank you for bringing us along on your journey.🥰
