def_drilling_sites {rmacrostrat} | R Documentation |
Define objects associated with eODP
Description
Obtain metadata for variables associated with the Extending Ocean Drilling Pursuits (eODP) project. By default, data for all drilling sites are returned.
Usage
def_drilling_sites(program = NULL, exp = NULL, site = NULL, sf = FALSE)
Arguments
program |
|
exp |
|
site |
|
sf |

Value
A data.frame
object containing, for each retrieved core:
-
epoch
: The name of the drilling program. -
leg
: The name of the expedition (formerly known as a 'leg'). -
site
: The name of the drilling site. -
hole
: The name of the drilling hole. -
lat
: The decimal degree latitude of the drilling hole. -
lng
: The decimal degree longitude of the drilling hole. -
col_id
: The unique identification number of the eODP column. -
col_group_id
: The unique identification number of the group to which the eODP column belongs. -
penetration
: The depth of the hole drilled, in meters. -
cored
: The amount of rock cored from the drill hole, in meters. -
recovered
: The amount of rock recovered from the core, in meters. -
recovery
: The proportion of rock recovered from the core. -
drilled_interval
: The interval drilled. -
drilled_intervals
: The number of drilled intervals. -
cores
: The total number of cores drilled at the hole. -
date_started
: The date on which drilling commenced. -
date_finished
: The date on which drilling concluded. -
comments
: Written notes assigned to the core. -
ref_id
: The unique identification number of the reference.
If sf
is TRUE
, an sf
object is returned instead, with a "geometry"
column that contains the spatial data instead of the lat
/lng
columns.
