I’m working with the Great Lakes Observing System to assess the viability of sharing our data through their data portal. https://seagull.glos.org/landing

I’m wondering if there is potential to send our data to Seagull through MMW?

Thanks.

These blips are occurring over the course of hours (roughly 4-6 hours from when depth starts dropping until it reaches it’s lowest point) though the time varies by occurrence.

They seem to be happening as temperature approaches the freezing point. I’ve attached a graph with temp for reference.

We’ve been seeing some strange depth and conductivity trends at a few of our sites. Quick drops in depth over a short period of time with a quick bounceback. See attached screenshot example. This occurred on the same days at multiple sites on different streams, but in the same region. At one site, conductivity dropped a bit at the same…[Read more]

Will it damage any other components?

So I just received a few more panels. The stereo jack cables are going in relatively easily with these. I think I received some damaged hardware, causing the stereo jack cable to be very difficult to get plugged in. And causing a bad connection to the logger.

Since we transitioned to the new panels it has been very difficult to get the stereo jack from the panel plugged into that adapter cable. Any recommendations on that are welcome.
