All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
Aerial photographs were taken at 3 islands in the Cronk group and 3 islands in the Frazier group of the Windmill islands where occupancy surveys in 2010-11 found breeding Adelie penguin populations. The photographs were taken to estimate the size of breeding Adelie penguin populations.
Photographs of the Cronk Island group were taken on the 2 January 2011. One flight was made along a northeast-southwest direction across the three main islands, Hollin, Midgley and Beall (see below). The flight started at 02:10:23 UTC and finished at 03:40:45 UTC. The SkyTraders crew were the flight and camera operators. The daily weather observations from Casey Station for 2 January 2011 were 14.0 hour of sunlight, winds from the North at 6-13 knots and 2/8 cloud cover.
Photographs of the Frazier Island group were taken on the 23 January 2011.
Aerial photos were taken from a CASA C212 airplane (VHA) flying at ~140 knots and ~750m altitude using a Nikon D200 camera with a 55 mm real lens which is converted to a 75 mm lens (including the focal length magnification factor of 1.5 for non-35mm format). The Nikon D200 camera was set to normal which allows for varied speed and aperture and was set on autofocus. A 3-second shutter closure interval was programmed using an external intervalometer. All photographs were recorded on the cameras internal memory card and downloaded after the flight was over.
Quality
There was some drift along flight lines that lead to a few gaps between photographs. The resolution of images from the Nikon D200 camera in this survey was not as good as from a Hasselblad H3DII-50 camera used in an aerial survey in the Davis region in the same year.
