Ob Tube

To start off our Sunday, I went to the Observation Tube (referred to as the Ob Tube) together with Susan, Maya, Isabel, and Martin.

I step awkwardly into the narrow tube, descend a ladder that chills my hands, and sit in a glass box under the sea ice.

Tight squeeze alright. No parkas allowed.

It is silent, save the cries of seals.

The bottom of the sea ice. 

There are science lectures twice a week in McMurdo, a great opportunity for teams to share what they are doing on the ice. Tonight at the galley, Kirsty and Dave presented wonderfully on ROSETTA-Ice.

Kirsty Tinto and Dave Porter answer questions.


Thanks for all the superb photos of the Ob Tube, Susan Howard!

Alec grew up in Belmont, MA and graduated with a degree in Geology in May 2017 from Colorado College. His senior thesis used gravity and magnetic data from the ROSETTA-Ice 2015-2016 field season to interpret and characterize the bedrock beneath the Ross Ice Shelf, West Antarctica. The project is an interdisciplinary effort with the aim of understanding the systems interaction between the Ross Ice Shelf, underlying water and bedrock through an airborne geophysical survey. Geophysics, along with remote sensing (of the cryosphere) and structural geology, are some of Alec’s overarching interests, which grew while working in Antarctica with members of the ROSETTA-Ice group during the 2016-2017 season. Alec is participating in field data collection once more this fall/winter (Antarctic summer). Interests outside of geology include reading, hiking, skiing and biking.
