High resolution digital aerial surveys of sea ice, portions of the Vestfold Hills and some islands along the Ingrid Christensen Coast, November 2010

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

本次作业详情简要列举如下：

- 3012、3113项目：本次作业包含长时距水上/海冰飞行任务，核心目标为"利用原位观测、航空探测与水下观测手段，研究南极海冰区春季物理与生物过程"。该任务原计划于抵达戴维斯站前开展，作业区域为远岸浮冰区。本次任务共完成2次专项科考飞行与1次应急海冰侦察飞行，专项科考数据采集总时长达5小时19分钟。

- 2205项目：本项目分为两级优先级任务：
优先级1：戴维斯站周边岛屿阿德利企鹅种群普查。本次作业为2009/2010年阿德利企鹅航空普查的重复任务，同步开展了加德纳岛（Gardner）、马格尼特岛（Magnetic）、拉格岛（Lugg）与特纳岛（Turner）特定岛屿/聚居区的地面计数，以对比航空计数与地面计数的结果。CEMP企鹅监测项目（Colin Southwell、Barbara Wienecke）的工作人员于2个作业日同步开展地面计数与航空飞行协调工作。飞行航线最初于2010年11月18日在晴朗光照条件下完成，随后于2010年11月20日在阴天环境下重复飞行，以对比无企鹅阴影时的图像成像质量差异。
优先级2：斯文纳群岛（Svenner Group）航空摄影勘测。本次飞行在750米高度开展，搭载150mm镜头，仅针对已知存在阿德利企鹅聚居区的岛屿实施作业。本次任务总飞行时长为5小时51分钟。

- 2425项目：本次任务为伍普伍普滑雪道（Woop Woop Skiway）开展勘测，作业区域面积达320平方公里。受时间限制，经与澳大利亚南极局航空运营部门（Steve Daw与Matt Filipowski）协商后，仅执行了每间隔一条航线的飞行作业。本次任务总飞行时长为4小时25分钟。

- 3154项目：本次任务为霍克岛（Hawker Island）巨型海燕聚居区拍摄航空照片，该聚居区正通过巢式摄像头开展监测。作业分别于2010年11月19日晴朗光照条件下与2010年11月20日均匀光照条件下各完成一次飞行。本次任务总飞行时长为22分钟。

- 3189项目：本次任务为戴维斯站附近韦斯特福尔丘陵（Vestfold Hills）开展禁核试条约监测设施候选场址勘测。本次任务总飞行时长为29分钟。
