Summary: Installed Licor GHG system, Installed solar system, collected the met data.
| West Pond
2012-05-02 I arrived with Dennis, Jaclyn and Sara about 12:30PDT. It was warm and sunny with some high thin clouds and a strong gusty breeze. The water level in the ponds was much lower – maybe 15 to 20cm. Frank said to ask Jim to prime the siphon. I called Jim and he said he would check. Jim later left me a phone message to say that he had primed the siphon. This may have been after we left and didn’t see any water entering at one of the inlets. The West Pond has a bunch more green tules showing up now, but still not dominantly green. While Dennis, Sara and Jaclyn got the scaffolding situated in the East pond, I put a Licor GHG1 system on the tower scaffolding. I also added an extension for the HMP60 so the folder arm was no longer blocked. The tower scaffolding seems tilted to the west. I’ll have to put some shims on the folding arm to level it better. The solar system went on the scaffolding across the road and a little south of the eddy tower. It is about 20feet into the pond. A 10 gage wire runs through a conduit under the road between the solar power and the tower. We need to add more conduit to protect the exposed wire from the otters. Three 140W panels were mounted on the scaffolding with security bolts. A second layer of security bolts is still planned Six deep cycle group 27 batteries went into two plastic boxes on the scaffolding boardwalk. A 30A Morning Star charger controller runs the system. I need to fuse the line to the tower. The 10 gage wire from the solar was patched into the tower system with wire nuts. These need to be moved inside the weather box if not swapped out with some other interconnect. Everything was running when we left. The solar system was reporting 14V, 18A solar, 1.8A load. We collected the met data. |
