In BlueCarbon: Estimation of Organic Carbon Stocks and Sequestration Rates from Soil Core Data

Dataframe containing field measurements of soil cores to estimate compaction caused by core collection.

Description

Example dataset of field measurements of cores collected by percussion. All variables needed to estimate core compaction are included. The 'core' ID is the same as in bluecarbon_data. 'sampler_length' is the length of the tube or sampler introduced in the soil from top to bottom. 'internal_distance' refers to the distance between the top of the sampler and the surface of the soil within the sampler (the same depth or lower than the surface of the soil outside). 'external_distance' refers to the distance from the top of the sampler to the surface of the soil outside the sampler. The reference used as "top of the sampler" is the same in the three measurements. Internal and external distances are measured after sampler insertion in the soil and before its extraction.

Usage

core_comp

Format

core_comp

A data frame with 78 rows and 4 columns:

core

character column with the id of the core

sampler_length

numeric column with the length of the sampler/tube used to extract the core

internal_distance

numeric column with the distance between the top of the sampler/tube and the surface of the sediment inside the sampler/tube after finishing inserting it in the soil and before extracting it

external_distance

numeric column with the distance between the top of the sampler/tube and the surface of the sediment outside the sampler/tube after finishing inserting it in the soil and before extracting it
