Collecting LiCOR 6400 in the rain in the Laupahoehoe Experimental Forest.

Sat-Sun: 11/21/10

• Completing reviews for Bio. Cons., For Eco., and JAG.
• Organized LiCOR 6400 data, verified curves, leaf drying.
• Rebuilt LiCOR 6400, new tubes, seals and chemicals.
• Finished Scan Line Corrections for Amazon land cover change project (70+ Landsat images).
• Job applications: organization and preparation.

Example linear correlations between SIB2 Modeled and field collected Net Carbon Assimilation Rates. This includes data from both the light and C02 response curves.

A dynamic light response over a 3 minute period following a replicated sunfleck (1500 ppm transition from steady state at 20 ppm).

home again, changing the filters for the c02 cartridges, the only good use for cigarettes, cheap filters…

Wednesday–11/18/10

Job applications, curve collection.

Improved LiCOR 6400 handle, reduces stress on attachment screws and allows for clipping a carabineer when collecting canopy measurements.

Second tripod used to collect location offsets from the differentially corrected stake. This particular offset allowed for curve collection in a forest gap 35 meters from the stake.

11/16/10–Tuesday

• Completed a job application.
• All Landsat images AutoMCU processed.
• Field work complete for the day, sensors up and running.

Interior forest sensors up and running

Sat-Sunday: 11/13-14/10

Field work setting up microclimate stations

Job applications

Hidden up there are two microclimate stations we spent 3 hours tree climbing to set up. Beautiful!

Thursday-Friday: 11/11-12/10

Thursday collecting LiCOR curves.

Notice abundant invasive species, including ginger, raspberry and guava, all within one small gap within one of the better native forests around. bummer!

At home the leaves are scanned at 600 dpi for area measurement.

Then oven dried at 55-65 C for 48 hours. Following this the samples are stored with desiccant until they are weighed, then analyzed for isotopes and nutrients.

Monday/Tuesday–11/10/10

1. LiCOR data collection
2. Checking on microclimate stations
3. Programming IDL procedure for writing large images (8-20 GB)
4. Job applications

Wednesday–11/10/10

• Article review
• Submitted job application
• Fixed computer issue resulting in frequent crashing
• Rebuilt LiCOR 6400, had leaks at tube seals and throughout the cuvette head. Ran full diagnostics. Runs perfect now! However, the tubes are a bit short so will look into ordering a replacement set.

Thursday–11/05/2010

• Repositioned microclimate stations
• Downloaded data and replaced desiccant in all datalogger cases
• IDL programming, I/O programs for large images
• Correcting SLC Landsat 7 Errors in newly processed Landsat imagery.

Sweet new tires, expensive but worth it for safety!

Upper elevation data download

Serious ginger invasion in our lower elevation traverse site, close to the climate tower. This will make for an interesting future project proposal.

Monday-Tuesday – 11/02/2010

Job applications sent (2).

New off road tires on car, it has been skidding in heavy rains, very dangerous for this windy rainy roads of Laupahoehoe!

Caught up on Scan Line Corrections of Landsat imagery for Amazon project.

Working on flowcharts for model using Visio, interesting flowcharting program.

Making 3D LAD map (a 22 GB image as floating point, yikes, needs to be converted to a byte array).
