The SOCEP research objective is to detect and document cetacean sightings and relevant environmental and other information throughout the voyage. The BROKE-West multidisciplinary voyage provides an opportunity to correlate sightings data with oceanographic and biology research conducted by other programs. Search effort is conducted over a broad range of weather conditions. The majority of Antarctic species are medium to large whales, with cues that can be detected in relatively high Beaufort sea states up to and including Beaufort Sea State 7.
The atlas shows the known distribution and abundance of each vascular species on Macquarie Island immediately prior to the commencement of control measures against rabbits in 1978. It gives a baseline against which changes in the vegetation can be monitored. The effects of the introduced vertebrates on the vegetation are discussed. Additional data are given on the habitat, gregarious performance and phenology of some species.
Two endemic orchid species, Nematoceras dienemum and N. sulcatum, are known from sub-Antarctic Macquarie Island. Several additional orchid populations on the island are reported and cleistogamy is documented in N. dienemum for the first time. The known population sizes, habitats and locations for both orchid species are documented here, and new information on their biology and population ecology is provided.
Collection of marine invertebrate specimens from the bycatch of pelagic and benthic trawls conducted by ANARE personnel. Collection methods included IYGPT net (88 samples from 39 sites), benthic trawls (22 samples from 21 sites), RMT net (5 samples from 5 sites), one drift net sample, one mud grab and several specimens from CTD winch wire.
Collected by RMT trawls during ANARE 1990/91 Voyage 6 AAMBER2 survey. 62 routine sampling sites were taken within the area 67 degrees to 78 degrees East, 65 degrees South to the Antarctic coastline, in a grid arrangement with approximately 30 nautical miles in latitude and longitude between sites. At each site the 0-200m water layer was sampled by a downward oblique haul with a rectangular midwater trawl RMT 1+8 net. Ten horizontal tows were also made with the RMT 1+8 to identify krill/zooplankton targets detected by the echosounders.
This data were collected on the sixth Nella Dan voyage of a long term field survey project being conducted by the Australian Antarctic Division, to collect distribution, abundance and population structure data for the krill Euphausia superba in the Prydz Bay region, Antarctica. A Rectangular Midwater Trawl (RMT 1+8) was used for the collection of ... larval and post larval (juvenile and adult) krill Euphausia superba, and other zooplankton. Three haul methods were used. At each station a shallow downward oblique haul was taken from the surface to 200m. At selected stations a deep downward oblique haul from 200m to 1000m was taken to collect early developmental stages of Euphausia superba. W…
Samples were collected at trawl stations (approximately every second CTD station), as well as opportunistically when something interesting was spotted on the Echosounder. The samples were collected with an RMT-1 plankton net and preserved in Steedman's solution. Upon returning to Australia, the samples were passed onto Kerrie Swadling, who split them with a Folsom plankton splitter so that between 400 and 1300 indivduials were counter per sample. Every organism was identified to the lowest possible taxon - in the case of copepods, usually to species and stage level. Other taxa are to species wherever possible. All the animals were counted and the results are expressed as abundance per 1000 …
Collected by RMT trawls during ANARE 1992/93 Voyage 6 KROCK survey in the Prydz Bay region, East Antarctica. KROCK is an acronym for Krill and Rock. (KROCK Expedition - see http://data.aad.gov.au/aadc/voyages/display_voyage.cfm?voyage_id=55)
The total number of Royal Penguins breeding on sub-Antarctic Macquarie Island is estimated at 848,719 pairs based on two methods of estimation. The sizes and locations of all 57 colonies are given as a baseline for future changes in the species abundance. Current estimates of the sizes of two colonies are compared with historical estimates made by the Australian Antarctic Expedition in 1912-13. Note that the total estimate is included in the Inventory of Antarctic Seabirds dataset as a single record.
Surficial bottom sediments have been collected from Prydz Bay, Antarctica from 5 voyages from 1981 to 1995. Devices used include gravity core, grabs, pipe dredge. Most collections are from 200 to 800 metres depth with the deepest at 3200 metres.
Historic field reports and other primary literature were re-examined and intrepreted into a consistent format for an analysis of the Southern Giant Petrel Macronetes giganteus census data within the Australian Antarctic Territory. Population data has been forwarded to Agreement on the Conservation of Albatrosses and Petrels (ACAP) for their species assessments.
Ground counts of King Penguin Aptenodytes patagonicuseggs, chicks, fledglings and adults at Gadget Gully on Macquarie Island (1993-2008 incomplete). Counts were obtained in the field by observers at Gadget gully. During the late 19th and early 20th centuries, when blubber oil fuelled house lamps, the king penguin population at Macquarie Island was reduced from two very large (perhaps hundreds of thousands of birds) colonies to about 3000 birds. One colony, located on the isthmus when the island was discovered in 1810, was extinct by 1894 and it took about 100 years for king penguins to re-establish a viable breeding population there. Here we document this recovery. The first eggs laid at Ga…
Census of Mawson region nesting sites for snow petrels and some wilson storm petrels.. Very little information is known about the distribution and abundance of Snow petrels at the regional and local scales. This dataset contains locations of Snow petrel nests, mapped in the Mawson region during 2004-2005 season. Location of nests were recorded with handheld Trimble Geoexplorer GPS receivers, differentially corrected and stored as an Arcview point shapefile (ESRI software). Descriptive information relating to each bird nest was recorded and a detailed description of data fields is provided in description of the shapefile (word document). A text file also provide the attribute information (fo…
