binfordDates: binfordDates

In shiggo/jezioro: Tools for Paleolimnological Analyses at the Paleoecological Environmental Assessment and Research Laboratory

Description

binfordDates uses the output of binfordRho and binfordActivity to calculate 210Pb dates using the Constant Rate of Supply (CRS) model.

Usage

binfordDates(binfordRhoOutput, binfordActivityOutput, LakeName = "Lake Name", 
CoreName = "KB1", CoreDate = 2006, CIC = FALSE)

Arguments

binfordRhoOutput	matrix or data frame containing the output data from binfordRho
binfordActivityOutput	matrix or data frame containing the output data from binfordActivity
LakeName	(defaults to "Lake Name"): name of the lake being analyzed
CoreName	(defaults to "KB1"): name of the core being analyzed
CoreDate	(defaults to 2006): year of core collection
CIC	(defaults to FALSE): logical to control whether to also calculate and plot CIC dates (NOTE: this was still being worked on when the functions were rendered obsolete, and remains incomplete)

Details

binfordDates determines the unsupported fraction of 210Pb activity using the procedure outlined in Binford (1990) and then calculates dates based on the constant rate of supply model. For input, it requires the output data from binfordRho and binfordActivity.

Value

binfordDatesOutput returns a table with 15 columns:

• IntTop: depth (cm) to the top of the analyzed interval

• IntBot: depth (cm) to the bottom of the analyzed interval

• IntMid: depth (cm) to the midpoint of the analyzed interval

• TTop: age (years) at the top of the interval

• SDTTop: standard error of the age at the top of the interval

• TBot: age (years) at the bottom of the interval.

• SDTBot: standard error of the age at the bottom of the interval

• SedRate: sedimentation rate (g/cm^2/yr).

• SDSedRate: standard error of the sedimentation rate

• SumTop: cumulative dry mass from the bottom of the core to the top of the interval

• DTop: date at the top of the interval

• DBot: date at the bottom of the interval

• DMid: date at the midpoint of the interval

• CICDMid: CIC Date at the midpoint of the interval

• OrgSedRate: organic sedimentation rate
