Overview of attributes

Tule Lake Sample no.:  A unique sample number used for all
measurements.
Core no.:  Identifies core.  Five cores were recovered from Tule
Lake. This document provides data from cores 1 and 2.
Drive no.:  Identifies location in the core.  Each core was
divided into drives numbered sequentially starting with 1 at the
top.  Some drives have been further divided into slugs indicated
by letters, starting with A at the top of the drive.
Drive depth:  The depth in meters of the top of the drive from the
top of the core.   Taken from drillerĀ¹s reports.
Sample depth in drive (m):  Midpoint of sample depth interval in
meters.
Sample depth in core (m):  Sample depth within drive (m) plus
adjusted depth from top of core.
Adjusted depth in core (m):  The depth in meters of the top of the
drive from the top of the core.  Depths for core 2 have been
lowered by 1.17 meters based on the location of the Trego Hot
Springs ash located in each core (see Bradbury, 1991).
Sample density (kg/m3):  Density of sample calculated from the
mass of the dried box samples used in magnetic mineral studies.
MSLF:  Low-frequency magnetic susceptibility in m3/kg.
FDMS:  Frequency-dependent magnetic susceptibility in percent.
IRM (1.2T):  Isothermal remanent magnetization from induction in a
1.2 tesla field at room temperature.  Expressed in Am2/kg.
IRM (-.3T):  Isothermal remanent magnetization from induction in
a -0.3 tesla field at room temperature.  Expressed in Am2/kg.
S:  (S Ratio) calculated as IRM (-0.3T)/IRM(1.2T).
HIRM: Hard isothermal remanent magnetization: HIRM is calculated
as: [IRM(1.2T) + IRM(-0.3T)]/2 and expressed in Am2/kg.
ARM:  Anhysteretic remanent magnetization in Am2/kg.

Total Carbon:  Percent of carbon (both organic and inorganic) in
sample.
Carbonate Carbon:  Percent of inorganic carbon in sample.
Organic Carbon:  Percent of organic carbon in sample.  Calculated
as total carbon minus carbonate carbon.
