Census of southern giant petrel colonies on Frazier Islands 12 December 2011Entry ID: frazier_sgp_12dec2011
Abstract: John van den Hoff (Australian Antarctic Division biologist) visited the Frazier Islands on 12 and 13 December 2011. He was assisted by Tim Gill (Field Training Officer), Dan Blight and Trevor Crews (Casey winterers) and Zane Hacker and Oliver Henshaw (watercraft operators).
Visits were made to Charlton, Dewart and Nelly Islands and four cameras, tripods and supporting solar power packs were ... deployed on Nelly Island. The main visit occurred on 12 December and a shorter second visit to check on the cameras was made on 13 December 2011. The cameras were installed to monitor the southern giant petrel colonies.
A count was made of the number of southern giant petrels in each colony.
A search for bird carcasses was made on Nelly Island with none found or collected.

Quality John van den Hoff supplied to the Australian Antarctic Data Centre as Oziexplorer files GPS data collected by Tim Gill using a handheld GPS. The data included points with longitude and latitude for the camera locations on Nelly Island and tracks representing the approximate boundaries of the southern giant petrel colonies.
GIS data was created from the GPS data. Polygons representing the southern giant petrel colonies were smoothed using the Smooth Polygon tool in ArcGIS 10 with the UTM zone 49 projection, the Paek algorithm and a tolerance of 30 metres.
