OIB - P-3 Orion 11/16/17 Science Report

OIB successfully flew the high priority Venable 01 A mission. This is a new flight, primarily designed to map the bathymetry beneath the Venable Ice Shelf. This and the Venable 01B flight are companion flights. Each flight by itself establishes a grid spaced at 20 km, and together they establish a 20 km grid.

OIB - P-3 Orion 11/14/17 Science Report

OIB successfully flew the Seelye Loop South sea ice mission. This mission represents a continuation of the IceBridge time series, repeating the southern portion of the same mission flown almost every year of Operation IceBridge. It targets gradients in sea ice freeboard and thickness along the “gate” connecting the tip of the Antarctic Peninsula with Cape Norvegia – although we cannot reach all the way to Cape Norvegia in the P-3 due to range constraints.

OIB - P-3 Orion 11/12/17 Science Report

This is a new flight, designed to improve the density of airborne gravity measurements over the Larsen C ice shelf. Most of the lines are designed along IceSat-2 ground tracks. We also directly overfly the Bawden Ice Rise.
 
The flight went very well with no weather impacts or major instrument issues. Noise was present in one channel of the MCORDS and Accumulation radar systems which will be investigated. Some window fogging was also present during a small portion of the flight for DMS.

OIB - P-3 Orion 11/04/17 Science Report

This mission represents a continuation of the IceBridge time series, almost repeating the near-shore flight line flown in 2009 and 2010 and the Endurance flight line from many OIB Antarctic campaigns along rough sea ice near the coast. For 2016 onward we replaced the near-shore line with a nearby IceSat-2 ground track covering the central beam pair.
 

OIB - P-3 Orion 11/03/17 Science Report

This is primarily a repeat flight, designed to re-fly a portion of a coast-parallel grid on the west side of Dyer Plateau, with grid lines spaced at 20 km. This grid is intended to assess dh/dt in this area, and on its south end it connects with a similarly-designed grid in the English Coast 03 flight. The remainder of this grid is flown in the companion South Peninsula A flight.
 

OIB - P-3 Orion 10/31/17 Science Report

This is a repeat flight, designed to assess dh/dt of several glaciers draining into the Larsen A, B, and C embayments. From north to south, these glaciers are the Drygalski, Hektoria, Crane, Melville, Starbuck, Flask, Leppard, Attlee, Gould, Demorest, and Gibbs. In addition to these glaciers, we repeat two lines over Scar Inlet, and several flowlines on the Larsen-C Ice Shelf. Finally we overfly the Bawden Ice Rise on the eastern edge of the Larsen-C, since it may contribute to the stability of the ice shelf.

IceBridge Launches Two Sets of Antarctic Flights

Scientists with NASA’s longest-running airborne mission to map polar ice, Operation IceBridge, completed a successful science flight on Oct. 29, inaugurating their 2017 survey of Antarctic sea and land ice. For the first time in its nine years of operations in the southern hemisphere, IceBridge will launch two consecutive, dedicated sets of Antarctic flights from two continents—South America and Antarctica—with two different aircraft and instrument suites.

OIB - P-3 Orion 10/29/17 Science Report

This mission roughly follows the southern leg of the baseline priority Seelye Loop mission (though about 300 km south of the nominal line), a mission flown almost every year of Operation IceBridge. It targets gradients in sea ice freeboard and thickness along the “gate” connecting the tip of the Antarctic Peninsula with Cape Norvegia – although we cannot reach all the way to Cape Norvegia in 2017 due to range constraints of the P-3. The mission was modified to coincide with an ascending TanDEM-X spacecraft ground track, in cooperation with Dr.

NASA Flights Map Summer Melt of Greenland Land Ice

Operation IceBridge is flying in Greenland to measure how much ice has melted over the course of the summer from the ice sheet. The flights, which began on Aug. 25 and will go on until Sept. 21, repeat paths flown this spring and aim to monitor seasonal changes in the elevation of the ice sheet.

NASA Scientists Seek to Improve Sea Ice Predictions

NASA researchers are working to improve their forecasts of the size of the Arctic sea ice cover at the end of the summer melt season — but the goal is not just to have a better prediction of sea ice coverage. The challenge of making summer sea ice forecasts allows scientists to test their understanding of the processes that control seasonal sea ice growth and retreat, and to fine-tune computer models that represent connections among the ice, atmosphere and ocean.
