See notes for lr05_t01-04_2016 for discussion of geomorph, macrotopo, and microtopo.


env_field_note:
No soil pit or els form due to closely spaced transects.


env_field_note:
No soil pit due to water depth. Estimated average water depth of transect, see point intercept measurements). RVT location is an upland slough, beaver pond, fed by groundwater except during ice dam backwater high flow events.


env_field_note:
Surf org ranges from 10-19; moved to 14 to avoid di


env_field_note:
This is a terrace. these rvts, 1-4 are either inactive overbank or abandoned, depending on definition


env_field_note:
EC meter does not appear to be working correctly.


env_field_note:
This is the data for 138d-t01-02. Ice damage to trees by scars and mowed down trees. No pit here done at really 138d-t01-01 location


env_field_note:
Beaver dam area. Transect on higher ridge than surrounding area. Topography on either side falls away. Had to move soil pit to 10 so not in low spot covered in water (also 13 was in a differrnt veg area than what we sampled).


env_field_note:
Moved plot slightly past start point to avoid drainage channel.


env_field_note:

env_field_note:
See point intercept notes re well locations and reconfiguring transects. Substantial alder mortality, believe a combination of insects and fungus. secondary channel of lower river, not a braided system at this point. Microtopo abundant dead/down wood and old channel features.


env_field_note:
RVT orientation 336deg, declination 0.See point intercept notes re well locations and reconfiguring transects. Substantial alder mortality, believe a combination of insects and fungus. secondary channel of lower river, not a braided system at this point. Macrotopo is a floodplain proximal to river levee, uncertain of correct code. Microtopo abundant dead/down wood and old channel features. Soil pit in floodplain high flow drainage area, lower in elevation that soil pit at LR04_T01-05_2016.


env_field_note:
During the field entering of this data the tablet locked me out. I used paper forms and re-entered data in Talkeetna. At the site we used R2-Garmin for our GPS. Trees along transects had ice scars along w/ cobble deposites on floodplain surface.


env_field_note:
Note; soil is the same as gw104 T0702. Same surface, same poplar forest.


env_field_note:
Off set aspesct to 35 because of wasp nest. Using gps R2-Garmin. Disturbance: ice scars on trees and some windthrown popbal on the ground. Soil pit: small buried organic layer at 4 cm, 7 cm, 9-10 cm, and another at 37-39 cm. Loamy sand in the top 7 cm. Coarse sand from 15-36 cm.

env_field_note:
Undulating terrain, perhaps from flooding/scouring. Hit multiple rocks (cobble sized) just under surface when probing around. Top O layer has a significant amount of sediment in it. First end photo had Incorrect label, took another photo after once we realized. Time of end photo will likely not match u0 withthe other photos from this plot. Evidevce of ice daming & flooding includrs cobbles and small boulders scattered on top surface and woody debris pushed up perpendicular to trees.


env_field_note:
Surface geomorph borderline abandoned--thick surf organics, organics w/in profile mostly incorporared into soil. Microtopo--old high water flow channel, small natural levee between here and river.

KLF did not enter max observed depths for rvts on 7/5-6, until this rvt.All soíl pits were a minimum of 42 cm observed depth.


env_field_note:
Thr transect is on a higher finger that seems like it is acting like a levee. Some organics through out.


env_field_note:
Did not hit cobble w/ probe, but obseved random cobble during pit excavation. Distubance: insects eating on leaves. Soil temp 10 C at 10 cm. Call channel deposit because site looks to be in old channel.


env_field_note:
Soil pit: organics 0-13 cm, loamy layer 13-26, and sand 26-44 cm. No real disturbance noticed. Macrotopo effected by large alder trunks growing parallel to surface.


env_field_note:
Note; To2-1-3 are located on a floodplain rectanguar patch cut from the adacent Opar forest. There appears to be a plow horizon down to 10 cm.

Used R2-Garmin for waypoint of the pit. The was ice scars on trees and cobble deposite. Buried organics at 5 cm, 7 cm, and 14-18 cm. Lots of roots in pit. Soil temp 12 C.


env_field_note:
Microtopo is matstr bases, not hummocks or graminoid tussocks. Unsurebif this is channel or overbank deposit, and were the break between the two is?

env_field_note:
Azimuth of transect 24. Check microtopo, matstr hummocks.some down wood, but matstr seems to drive microtopo. No visible boulders/cobbles. No disturbance code for ice dam flooding  deposition.


env_field_note:
Large amount of ice damage from scars to mowed down trees. Rock piles deposited by ice also were present. No burried organic layers obsevered.

env_field_note:
Upland slough behind beaver dam. water depth average across transect.


env_field_note:
Loamy to 19 cm, then sandy with a burried O layer at 36. Moved transect endpoint ~ 15m toward start point to avoid drainage. Kept same azimith.


env_field_note:

env_field_note:
estimated mean water depth for transect, please use water depths recorded at point intercept plots. Upland slough, beaver pond, groundwater fed except ice dam backwater flooding.

RVT oriented at 35deg,0 declination.disturbance code ngfd for ice-jam flooding. Microtopo revorded as hummocks, but really these are matstr bases causing microtopo variation.


env_field_note:
Note,this is a terrace. abandoned, perhaps.


env_field_note:
Undulating terrain, possibly from flooding. Warbler nest. Sandy in lower part of pit.


env_field_note:
