Scott Ensign

@ensign and others (Rachel Johnson, Matt Gisondi, David Bressler, @hicks and a few more) have put a lot of work into that manual!

Hm. Thanks @srgdamiano, thats one way of doing it. The use case I envisage is pretty simple. Lets take a single technician with a portable water quality monitor, like a YSI or something. He/She drops it into a river at Position A, records data. Then turns device off, moves to Position B, records data etc etc. Once “home” uploads the data to…[Read more]

@ensign – yup, it’s a nice video. But… creating a video like that automatically for every set of uploaded trajectory data is just a little bit more difficult than making a simple plot with time on the x axis.

The WinRiverII software for the moving acoustic Doppler current profilers that we use to take discharge measurements has some nice…[Read more]

Hm. You have the LiPo plugged in in addition to the USB, right?

Are you sure you have service and the antenna is well connected? Don’t yank the antenna off unless you really have to; those u.Fl connectors are fragile and after 3 or 4 times of being disconnected and reconnected they stop working.

Have you ever gotten your XBee3 to connect?…[Read more]

Thanks @ensign and @srgdamiano, for your reply. Scott, I saw a write up of your floating buoy some time ago and really wanted to find out what happened to it. That was cool stuff!

My project is a little lengthy to explain but I would love your input – I’ll call next week if that is ok with you. Can you pm me a good time/number to call?

Many thanks!

I don’t know how “unusual” trajectory data is, but, at least in long term stream monitoring, it’s definitely far less common than fixed station monitoring. That type of data is also harder to manage, visualize, or conceptualize. I’d guess if others don’t support…[Read more]

@ensign has done some work with a moving/drifting sensor stations: https://www.fondriest.com/news/hydrosphere-drifter-brings-lagrangian-sampling-freshwater.htm

The way Monitor My Watershed’s data portal is set up right now is very “site-centric” – the web pages are just not set up to accept moving sensor data like you would generate. The…[Read more]
