Lake Fryxell Circumnavigation Metadata

2 files exist:
1) lf_transect_data.csv
2) lf_survey_data.csv

Topographic data was acquired with a kinematic, survey-grade GPS unit.  Field data was collected in 
kinematic mode around the lake and edge of wetted zone, and in static mode at each transect sampling 
or measurement locaiton.  Data was post-processed to be corrected with base-station data collected at 
a benchmark at Lake Fryxell camp. 

***********************************
In lf_transect_data.csv, data is organized in the following columns:
LFID - Lake Fryxell point identification, as T#L#, where T# is the transect number, and L# is the 
locaiton number within the transect (1-5, where 1 is dry soil and 5 is lake edge)
northing_(m) - northing in meters, UTM
easting_(m) - easting in meters, UTM
elevation_(m) - elevation relative to EGM 96 approximates sea level
active_layer_depth_(cm) - depth to resistance for manually pushing a t-bar thin, rigid rod into the soil
Sieve1(%) - percent of soil sample retained on the 4.75 mm size sieve
Sieve2(%) - percent of soil sample retained on the 2.00 mm size sieve
Sieve3(%) - percent of soil sample retained on the 425 um size sieve
Sieve4(%) - percent of soil sample retained on the 75 um size sieve
pan(%) - percent of soil sample that makes it into the pan below all 4 sieves

NOTE that soil samples were collected at all locations within a transect every 5 transects or so.


***********************************
In the lf_survey_data.csv, data is organized in the following columns:
LF_pt_number - Lake Fryxell point identification number, as determined by GPS survey equipment
point_type - either "shore" for a shoreline point, or "wet zone" for the outside edge of the wetted zone
date_aquired - date (DD-MMM-YY) that this point data was collected
northing_(m) - northing in meters, UTM
easting_(m) - easting in meters, UTM
elevation_(m) - elevation relative to EGM 96 approximates sea level
