marcott.proxies: Climate proxy data from Marcott et al (2013)

In EarthSystemDiagnostics/climproxyrecords: Published climate proxy records

Description

The climate proxy data supplied as supplementary online material with the publication, Marcott et al (2013), was read into R from the .xlsx file and reformatted into a handy format for use in R.

Proxy.type		Proxy type
Proxy.value		Proxy value
Published.temperature	deg C	Published temperature
Proxy.depth	cm	Proxy depth
Proxy.depth.type		Proxy depth type

Corrections

Proxy "GeoB 6518-1 (MBT)" was excluded as it seems to have duplicated temperature data and no raw proxy data.

Location information for proxy "Agassiz & Renland", which is the mean of two proxy records, was replaced with the mean location, so as to ensure a numeric value.

For proxy "MD01-2378", latitude was changed from 13.1 to -13.1
