Borehole optical televiewer logs from the southern sector of Larsen C Ice Shelf, Antarctic Peninsula, November-December 2022
These are digital optical televiewer logs of two boreholes drilled by hot water to 120 m (Site 1) and 160 m (Site 2) on Larsen C Ice Shelf, Antarctic Peninsula. Boreholes were drilled in December 2022 to investigate the internal properties of a suture zone (Site 1) and a meteoric ice band (Site 2) of an ice shelf, as part of the NERC-funded RiPIce (Rift Propagation for Ice sheet models) research project.
NERC standard grant NE/T008016/1.

Methodology:
The datasets are optical televiewer logs from two boreholes drilled to 120 m (Site 1) and 160 m (Site 2) on Larsen C Ice Shelf, Antarctica, in December 2022. They were acquired using a slim-hole optical televiewer borehole probe manufactured by Robertson Geologging Ltd, comprising a 360 degree camera. Boreholes were logged whilst the optical televiewer was travelling up the borehole.
The optical televiewer has internal LEDs to illuminate the borehole wall, indicated by a % lighting level controlled by the user. Lighting changes were made whilst logging, as follows:
RiPIce OPTV Site1
Depth (m),Lighting (%)
25.74 - 45.58,60
45.58 - 45.61,55
45.61 - 48.80,80
48.80 - 54.08,85
54.08 - 57.97,90
57.97 - 82.40,95
82.40 - 82.94,90
82.94 - 88.25,100
88.25 - 88.34,95
88.34 - 88.76,90
88.76 - 119.94,100
RiPICE OPTV Site2
Depth (m),Lighting (%)
1.97 - 50.30,50
50.30 - 69.90,70
69.90 - 159.97,90
Data collection:
Logs were acquired using Robertson Geologging OPTV probe, mini winch and Micrologger II.
Data quality:
Images are unaltered from those logged in the field. The OPTV technique is described by Hubbard et al. (2008).
