 Cliff,Make sure if you put R-300 on a boat to NZ there is room for Gamma!Hank

 1,923 miles, Devine Texas to Yellow Bay in Montana, yes quite a tow.  Having said that, Maxi and I towed the R-300 1,163 miles to Islamorada in 2013 and 2017 and 1,377 miles to Lake Tahoe this year.  To me it all part of the adventure!   Now if I could just justify putting her on a boat to New Zealand, that would be quite a trip.
Best Regards and a ?Happy Christmas to you Alan.

2019 Flathead Lake Expedition

Since David mentioned his goal in getting his boat ready fordive next year in Montana, I thought I would update the Psub community on the expedition.  On August 5-9, 2019, the 2019 Flathead Lake Expeditionis planned.  This is a joint effort betweenInnerSpace.Org https://www.innerspacescience.org/and the Flathead Bio Station https://flbs.umt.edu/newflbs .FLBS is operated by the University of Montana. I am the point person for this Expedition from the InnerspaceScience/PSub side and Jim Craft,  https://flbs.umt.edu/newflbs/about-flbs/people/page-elements/flbs-people/people/jim-craft/ from the FLBS, UM science side. TomBansak, http://flbs.umt.edu/newflbs/about-flbs/people/page-elements/flbs-people/people/tom-bansak/, the assistant director at FLBS, is also working closely with Jim Craft on theExpedition.  Organizationally, this Expeditionwill be structured much like the 2018 Lake Tahoe Expedition.  The base station for the dive is going to bethe FHBS facility at Yellow Bay on the west side of the lake.  At this time two psubs are committed tocome.  Hank Pronk is bringing NektonGamma and I am bringing the R300.  IfDavid is able to finish fabrication and testing by then, then he is welcome to bringSeaQuester.  Jim Craft is working withhis FLBS colleges to develop the science objectives which will primarily becompleted with Nekton Gamma as she can take a passenger.  Gamma will be fitted with an instrumentationpackage, the Hydrolab DS5 - Multiparameter Data Sonde https://www.ott.com/en-uk/products/water-quality-2/hydrolab-ds5-multiparameter-data-sonde-56/.  FLBS has two of these data sondes but theymay have one of these committed on an existing research project.  If it is available, it will be mounted on theR300.  These data sondes log Temperature,Conductivity, Depth, pH, Oxygen Reduction Potential (ORP), Dissolved Oxygen(LDO), Dissolved Oxygen (Clark Cell), Turbidity, Chlorophyll a, Blue-GreenAlgae, Rhodamine WT, Ammonium, Nitrate, Chloride, Total Dissolved Gas (TDG), andAmbient Light.

One of the planned science missions is for Gamma to do asubmerged transect from the mouth of the Flathead river at the north of thelake to Big Arm Bay logging with the DS5 and capturing bottom samples along thepath.  Hank is in the process of addingthe capability to Gamma to take these samples. A bathymetric map of the lake can be found at http://flatheadlakers.org/wp-content/uploads/2017/03/bathymap.pdf

Dr. Josef Crepeau, Associate Prof. Mathematics, University ofMontana has agreed to provide dive support with his 19ft Boston Whaler. Theplan is for Josef to use his vessel to tender the R300 and FLBS’s 30 footresearch vessel will be tendering Nekton Gamma. We have a number of psubbers that are tentatively involved:
Cliff RedusRick MaxwellHank Pronk and wifeJon WallaceDoug Suhr Jr.Doug Suhr Sr.Alec Symth (Provisional depending on his son’s racingschedule)David Colombo and wife

Limited sleeping accommodation for some of the psub contingenthas been provided at FLBS base station using their faculty cabins but thesecabins now are fully committed.  Thereare a number of hotels in Polson but be aware that reservation would need to bemade early for these as they tend to fill up fast for the summer.  We have a local contact, Masson Niblack, who livesin Polson working with us as well for local info.

Along with the long submerged transect that Hank is going tomake, we will also be doing a joint night dive to see the difference in themarine community between day and night.  Thereare several wall dives that are also planned. As we get closer to the date, we will get a better picture of the planneddives.

On Friday afternoon August 9th, FLBS is hostingan open house for the public and has asked Innerspace Science to have the subs availablefor 400-500 students.
Flathead Lake is one of the largest clearest lakes in theUS.  The 2019 Flathead Lake Expedition shouldbe a hoot!Cliff
