OK. Horacio and I think if you want to measure the Anaktuvuk tomorrow afternoon that would be fantastic & very helpful. Hope you are not joking. Attached is a map and diagram of what we did today, it might help you find a route through the mess. It is SUPER braided everywhere and there is flow through the floodplain (over bank full) as of today. Kind of tricky. We just did LONG downstream diagaonal slow drifting transect, except in the super fast parts we had to use the motor and then had some cavitation at the sensor, but it wasn't too bad. We have a permanent GPS base station set up at the river if you want to tie into that for RTK. Ken will have to clue you in on the radio address.

The boat is ready to go and there are life jackets in the culvert but we have the rover GPS set up and the antennae and GPS poles for mounting.

We only have 1 tape down spot left located just to the north of the ISCO sampler (TP4) w/ yellow flagging if you can get a tapedown during the measuremnt. Beware of that area because there is alot of rebar there and then there is a steep drop off where the main cutbank is (it is submerged) There is a higher terrace also, but don't get close to that in the vicinity of the station or you will puncture your boat! on all the junk above the lower terrace.

Email us in the a.m. if you think you are going to do it and let us know if you want us to call you. You have our sat phone numbers also, but we usually don't have them close to us. We'll be at the Chandler, either at the culverts or at the lower station (located 0.5 miles downstream across from "Ice Jam Island") most of the day. At the lower station we have to do some repairs and surveying, the tape down area got trashed by the jam and there is a 25 foot ice pan right at our PT area. I think Horacio will get over to the Anaktuuvk to survey and do water levels later in the day.

Yes there is stuff to hose clamp onto (GPS over the ADCP on the ADCP pipe, but you'll need a small pole, and another pipe to clamp the antennae to (separate from the GPS pole).

You would need everything except a base station, which we have up and running, Ken can send you the info.

You'll need to bring your adcp, battery, and rover GPS setup (w/ antennae and a GPS pole) in the boat. I don't think we have a battery out there, but maybe we can drop one off because Horacio needs to swing by and pick up the suspended sediment profiler thing there in the a.m., so maybe he can drop a battery there.

No GPS scripts changed. THe only think we did was change some settings on the radios, which Ken will clue you in on.

You might want to bring your rio grande with the 1 1/2 " flange and top plate already attached. I leave it on all the time and just pop off the set screws and take the whole ADCP + flange + plate with me. There is an allen wrench attached the frame, but you might want a spare. THere are some hose clamps for set up but you might want a nut driver. Range finder, GPS/radio, etc. There is a big rope that looks like a boa constrictor in the culvert if you need it.

There is less than half a tank of gas (according to Rob). We have gone out for 2 days and today we were out there alot w/ the sediment work so you should be okay, but maybe we can bring a can out for you if Horacio goes out there to get the sediment profiler thing.

I changed the base radio, which is in the Anaktuvuk logger box, to point-to-point slave mode, menu 0 entry 1. The rover radio then needs to be configured as master, menu 0 entry 0, and the callbook set to call that radio, or to call it through the Tuvuk repeater.

The freewave master/slave thing only means which end initiates the call, otherwise the radios are just peers, so this doesn't change anything other than that.

We operated through the tuvuk repeater, and hope that the same settings will work on the Chandler. If not we'll need to set up a base there as usual (mainly if tuvuk isn't visible from the reach, which it probably is), but again with the base as slave, rover as master radio.

Tuvuk is used to reach the Chandler bluffs met site, and also the new Chandler 'drowned river rat' site. It may be busy when you try to connect, but those calls should end withing 4 minutes. We hope to get going early on the Chandler and so should be done using the repeater and base by the time you need it.

There's probably no reason for you to use tuvuk. The Anaktuvuk base has a 10 dB omni antenna mounted several meters high, and should have good visibility for the gauging reach. The base number is 906-6040, and in case you need it (or just want to try), the tuvuk number is 882-5372.
