Line by line

Expecting to be scheduled only for backup this week with deinstallation Friday night, the ROSETTA team cheered at the dinner table upon news that our flights were in fact scheduled as priority. If all goes well, these nine more flight opportunities are enough to obtain 10km resolution over the whole Shelf! Since Monday morning we have flown three consecutive flights and hopefully the night shift takes off shortly, to make that four.

The previous two flights were lines north of Roosevelt Island. In both flights, cloudy skies forced us to fly above 1800 meters; survey elevation is usually around 950 meters. Today’s flight brought Chris, Grant and I all the way to the southern portion of the Ross Ice Shelf, beyond Crary Ice Rise, where our grid has the least data coverage.

Sure, 7.2 hours is a long time to spend in a plane. But the views are utterly spectacular.


Sorry, the window is quite dirty.

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.
