ODP677: Marine core ODP677

In mcrucifix/pleistocene: Datasets of glacial cycles (ice and ocean)

Description

Eastern Tropical Pacific core ODP-677 PI: Nicholas J. Shackleton Core/Site: ODP-677 Latitude: 1.12.00N ( 1.2) Longitude: 83.44.00W ( -83.73333) Water depth. m: 3450

Usage

data(ODP677)

Format

A data frame on the following variables.

Variables:
depth	Depth (cm)
yrBP	radiocarbon years B.P. (Libby half-life; B.P. = 1950)
d18Oforams-b	delta O18 PDB (Benthic Foraminifers)
d18Oforams-p	delta O18 PDB (Planctic Foraminifers)
notes	Species

Details

The time scale is astronmically-tuned, and motivated a revision of the date of the Brunhes-Matayama magnetic reversal.

Note

The following attributes have been defined, corrsesponding to benthic species, uvigerinaes, and gruber. $benthics "CIB " "CIBKULL " "CIBMELAT" "GLOBCASB" "GLOBOBUL" "GLOBOCAS" "GLOBOGYR" "GLOBORID" "GLOBORIG" "GYRGLOB " "GYROID " "HELEGANS" "LATIC " "ORIBULGL" "ORID " "ORIDBUL " "ORIDBULL" "ORIDGLOB" "ORIDGYR " "ORIDMIX " "ORIDSBUL" "ORIDUVIG" "ORIGLOBU" "ORIGYRGL" "ORIGYRPY" "ORIGYRST" "PWUELCIB" "PWUELCIL" "PWUELL " "PWUELLAT" "PWUELMEL" "PYRGGLOB" "PYRGO " "SBULGBUL" "SBULL " "SBULLGBU" "SBULLGLO" "SBULPYRG" "STYLOS "
