Summary
Abstract:
Taken from the report:
This document describes the results of the use of the APPLS (Aerial Photography Pyrometer LiDAR System) during underway science (sea ice) on the way to Davis, and later at Davis during resupply 2010/2011 (November 16 to 20, 2010). This document is primarily for Science Technical Support use. Portions of the report can be used to provide information on the results obtained to other parts of AAD.
Some of this aerial photography has also been conducted in support of various AAS projects:
AAS 3012 (ASAC_3012)
AAS 3113 (ASAC_3113)
AAS 2205 (ASAC_2205)
AAS 2425 (ASAC_2425)
AAS 3154 (ASAC_3154)
AAS 3189 (ASAC_3189)
A short list of the work carried out:
- 3012, 3113
This activity involved long duration over water/sea ice flights for the purposes of "Investigation of physical and biological processes in the Antarctic sea ice zone during spring using in-situ, aircraft and underwater observations".
This activity was scheduled for prior to Davis, over pack ice far from shore.
Two science specific flights were made, and one opportunistic (sea ice reconnaissance), for a total of 5 hours 19 minutes of data collection for dedicated science
- 2205
Priority 1 - Adelie Penguin Census Survey on the Islands in the Davis vicinity
This task was a repeat of aerial census of Adelie penguins, conducted in 2009/2010 with coordinated ground counts of specific islands/colonies on Gardner, Magnetic, Lugg and Turner Islands. The ground counts were performed at the same time as the aerial survey, to compare aerial versus ground counts.
Personnel from the CEMP Penguin Monitoring Program (Colin Southwell, Barbara Wienecke) performed ground counts coordinated with the flying on two days.
The Flight lines were initially done on 2010/11/18 in bright sunlight, and then repeated on 2010/11/20 during overcast weather to compare the different image quality due to lack of shadows cast by the penguins.
Priority 2 - Aerial photographic survey of the Svenner Group Islands
Flights over Adelie Penguin colonies were performed at 750m, using 150mm lens, and then only over the islands known to host Adelie colonies.
Flying time total = 5 hours, 51 minutes
- 2425
This task was to survey the Woop Woop Skiway, over an area of 320 square kilometres. Due to time constraints, only every 2nd line was flown after consultation with AAD Air-operations (Steve Daw and Matt Filipowski).
Flying time total = 4 hours 25 minutes
- 3154
This task was to capture an aerial photograph of a Hawker Island Giant Petrel colony, being monitored by nest cameras. A run was conducted on 2010/11/19 in bright sunlight and also repeated on 2010/11/20 in flat light.
Flying time total = 22 minutes
- 3189
This task was to survey potential sites, in the Vestfold Hills near Davis, for a Nuclear Test Ban Treaty monitoring installation.
Flying time total = 29 minutes
