Deployment with surface-referenced depths
Lowest node is closest to surface; logger pgm detects and stores the addresses of all active nodes when it starts running.
 (17-node T-string deployed with wire rope attached to horizontal PVC pipe acting as buoy next to raft)
 (Node 12 is ~0.5m deep at dock; I may aim for 0.1m deep at lake center to better estimate surface temperature)
