Wildlife observations made on the IDIOTS cruise of the Aurora Australis in the 1999-2000 seasonEntry ID: ASAC_1101_Wildlife
Abstract: This dataset is a subset of the Wildlife on Voyage dataset, and comprises the wildlife observations made onboard the Aurora Australis on the IDIOTS cruise of 1999-2000. There were 45 observed species from 3222 observations. The technique used for collection was that prescribed by the Biological Investigation of Marine Antarctic Systems and Stocks (BIOMASS) Working Party on Bird Ecology.
This work was incorporated into ASAC (AAS) projects 1101 and 2208.
1101 - Biology of the Mertz Glacier Polynya
2208 - Variability in the distribution and abundance of seabirds in the Southern Indian Ocean

Quality Sightings are referenced to the observer, the cruise, ship name, date and time.
Birds were counted within 300m off of one side of the ship whenever the ship
was underway. Weather conditions and ocean conditions were recorded
simultaneously and it was noted when sightability decreased to less than 300m.
Position was recorded ... from ships GPS.
Strip width was regularly checked using the Heineman method (Heineman 1981).
Ship speed and course and position were recorded regularly. Birds behavior
(flying, sitting on the water, feeding) were noted for each bird sighting. Some
inconsistencies in the estimation of how much area was surveyed (based on ships
speed and course) when ship changed course to avoid ice or had to back up to
crash through ice.
Transects with confirmed absence are reported. Absolute densities are possible
to estimate because bird flight direction and ship speed and direction were
Horizontal Positional Accuracy Report: Latitude and Longitude (seconds) were
recorded at the beginning and end of each transect and updated about every ten
minutes. Exact locations can be obtained through extrapolation of distance
traveled during these intervals knowing the course and ships speed.
Vertical Position Accuracy: Altitudinal variations were minor. Height f bridge
above water varied slightly with swells and ice conditions. Strip width was
calibrated for each observer based on their height above the water.
Access Constraints This study was funded by National Science Foundation Office of Polar Programs
grant number OPP9725071 awarded to Dr. George L. Hunt, Jr. of the University of
California, Irvine, Department of Ecology and Evolutionary Biology. This data
set was created as part of the international investigation of the North Water
polynya which was initiated under the Arctic Ocean Sciences Board.
