Fieldwork was undertaken on Voyage 7 of 1997/98 season (April/May 1998) aboard Aurora Australis. The plan was to repeat the transect sampled in September 1996 to investigate seasonal differences between Spring and Autumn. We anticipated being able to sample further south on this voyage because the ice would be at close to its minimum extent. Sixteen stations were successfully sampled with the MIDOC multiple opening/closing net at 1000-750m, 750-500m, 500-250m and 250-0m depth ranges. The stations were at the following approximate positions: 47o14S:145o43E, 47o57S:145o14E, 49o54S:144o28E, 50o28S:144o15E, 51o15S:144o45E, 52o04S:144o24E, 52o59S:144o52E, 54o00S:145o01E, 53o59S:145o56E, 53o37S:144o32E, 57o00S:145o08E, 59o00S:144o56E, 58o12S:145o44E, 63o41S:139o03E, 64o17S:140o41E, 61o03S:139o40E. It was originally intended to sample 18 stations, some of which during both day and night, for a total of 26 samples, but consistently bad weather and the necessity to divert to Davis to pick up helicopters prevented the full programme being completed. However, data for the transect sampled in September of 1996 are available as a collection in the biodiversity database at the provided URL - MIDOC Fish catch from 1996/97 Voyage 1 WASTE (WOCE Antarctic Southern Transect Expedition).

Metadata record for data expected ASAC Project 11 See the link below for public details on this project. From the abstract of the referenced paper: The Australian Antarctic Division carried out an extensive sampling program for pelagic and benthic fauna in Prydz Bay, Antarctica (Indian Ocean sector) in January to March 1991. A total of 341 cephalopod specimens comprising 256 squids and 85 octopods were captured for study. This preliminary report presents capture records of eight species of squids: Brachioteuthis sp., Kondakovia longimena, Bathyteuthis abyssicola, Mastigoteuthis psychophila, Psychroteuthis glacialis, Alluroteuthis antarcticus, Mesonychoteuthis hamiltoni and Galiteuthis glacialis. The Octopods captured are Megalehedone senei and several species of Pareledone. Psychoteuthis glacialis is reported to congregate on the bottom near the shelf edge at the depth of 400-600 metres. No distinctive pattern in diel vertical movement was found for any of the species captured. Evidence suggests the existence of ontogenetic descent in Galiteuthis glacialis. Cephalopod catches from the extensive sampling program for fishes and zooplankton were studied. For the pelagic fauna, half-hour duration IYGPT hauls were taken at three depths at 63 stations evenly distributed over Prydz Bay area. The three depths fished by the IYGPT at each station were near the surface, near the bottom or 800 m whichever was less, and the midpoint between those two depths. The 63 stations coincided with most of the stations used in the zooplankton sampling program which employed an RMT 1 + 8 net and sampled from 0-200 metres. Additionally 21 benthic samples were taken using bottom trawl, fished for half hour duration on the shelf of Prydz Bay.

This dataset contains the results from studies of the Weddell Seal (Lepotonychotes weddellii) in the Vestfold Hills region, Antarctica. Results from tagging surveys, photographs and aerial surveys since 1973 are reported. Numbers, life stage, sex, moult stage and migration patterns have been reported. Fecal samples have been collected and from the otoliths, vertebrae, cephalopod beaks and crustacean remains, the diets and feeding habits have been investigated. Many of the results are reported in the document. This metadata record encompasses ASAC projects 89, 95 and 199 (ASAC_89, ASAC_95, ASAC_199).

2018-08-10 - these data have been superseded by a new metadata record and dataset - see the provided URL for more details. This record describes a compilation of trophic data from across the Southern Ocean. Data have been drawn from published literature, existing trophic data collections, AADC data sets, and unpublished collections. The database comprises two principal tables. The first table relates to direct sampling methods of dietary assessment, including gut, scat, and bolus content analyses, stomach flushing, and observed feeding. The second table is a compilation of stable isotope values. Each record in these two tables includes details such as the location and date of sampling, predator size and mass, prey size and mass, and estimates of dietary importance. Names have been validated against the World Register of Marine Species (http://www.marinespecies.org/). The schemas of these tables are described below, and a list of the sources used to populate the tables is provided with the data. A range of manual and automated checks were used to ensure that the entered data were as accurate as possible. These included visual checking of transcribed values, checking of row or column sums against known totals, and checking for values outside of allowed ranges. Suspicious entries were re-checked against original source. Apparent errors that could not be resolved were marked as such in the QUALITY_FLAG column, with the reason in the NOTES column. Notes on names 'Sp.' indicates unidentified members of a genus (e.g. 'Pachyptila sp.'). For unidentified taxa at other taxonomic levels, the taxonomic name has been used (e.g. Amphipoda, Myctophidae, Decapoda). Uncertain species identifications (e.g. 'Notothenia rossii?' or 'Gymnoscopelus cf. piabilis') were assigned the genus name (e.g. 'Notothenia sp.'). Original names were retained in a separate column to allow future cross-checking. WoRMS identifiers (APHIA_ID numbers) were recorded with each matched taxon. Grouped prey data in the diet sample table need to be handled with a bit of care. Papers commonly report prey statistics aggregated over groups of prey - e.g. one might give the diet composition by individual cephalopod prey species, and then an overall record for all cephalopod prey. The prey_is_aggregate column identifies such records. This allows us to differentiate grouped data like this from unidentified prey items from a certain prey group - for example, an unidentifiable cephalopod record would be entered as Cephalopoda (the scientific name), with 0 in the prey_is_aggregate column. A record that groups together a number of cephalopod records, possibly including some unidentifiable cephalopods, would also be entered as Cephalopoda, but with a 1 in the prey_is_aggregate column. See the notes on prey_is_aggregate, below. Schema: Diet sample table - LINK_ID: The unique identifier of this record - SOURCE_ID: The reference number of the source of this data record. The list of references is provided with the database and also kept at: http://data.aad.gov.au/aadc/trophic/?tab=3 - LOCATION: The name of the location at which the data was collected. - WEST: The westernmost longitude of the sampling region, in decimal degrees (negative values indicate western hemisphere longitudes) - EAST: The easternmost longitude of the sampling region, in decimal degrees (negative values indicate western hemisphere longitudes) - SOUTH: The southernmost latitude of the sampling region, in decimal degrees (negative values indicate southern hemisphere latitudes) - NORTH: The northernmost latitude of the sampling region, in decimal degrees (negative values indicate southern hemisphere latitudes) - OBSERVATION_DATE_START: The start of the sampling period (UTC) - OBSERVATION_DATE_END: The end of the sampling period (UTC).

Values 'C1'-'C3' refer to calyptopis larval stages of euphausiids. 'F1'-'F6' refer to furcilia larval stages of euphausiids. 'N1'-'N6' refer to nauplius stages of crustaceans. 'Copepodite 1'-'Copepodite 6' refer to developmental stages of copepodites - PREDATOR_BREEDING_STAGE: Stage of the breeding season of the predator, if applicable. e.g. 'brooding', 'chick rearing', 'nonbreeding', 'posthatching' - PREDATOR_SEX: Sex of the predator. 'male', 'female', 'both', or 'unknown' - PREDATOR_SAMPLE_COUNT: The number of predators for which data are given. If (say) 50 predators were caught but only 20 analysed, this column will contain 20. - PREDATOR_TOTAL_COUNT: The total number of predators sampled. If (say) 50 predators were caught but only 20 analysed, this column will contain 50. - PREDATOR_SAMPLE_COUNT: The identifier of this predator sample. PREDATOR_SAMPLE_ID values are unique within a source (i.e. - SOURCE_ID, PREDATOR_SAMPLE_ID pairs are globally unique). Rows with the same SOURCE_ID and PREDATOR_SAMPLE_ID values relate to the same predator individual or population, and so can be combined (e.g. for prey diversity analyses). Subsamples are indicated by a decimal number S.nnn, where S is the parent PREDATOR_SAMPLE_ID, and nnn (001-999) is the subsample number. Studies will often report detailed prey information for a large sample, and also report prey information for various subsamples of that sample (e.g. broken down by predator sex, or sampling season). - PREDATOR_SIZE_MIN: The minimum size of the predators in the sample - PREDATOR_SIZE_MAX: The maximum size of the predators in the sample - PREDATOR_SIZE_MEAN: The mean size of the predators in the sample - PREDATOR_SIZE_SD: The standard deviation of the size of the predators in the sample - PREDATOR_SIZE_UNITS: The units of size.

For example, a study might give a number of individual squid species records, and then an overall squid record that encompasses the individual records. Use the PREY_IS_AGGREGATE information to avoid double-counting during analyses. If there no entry in this column, it means that this information is not included anywhere else in the database and can be used freely when aggregating over taxonomic groups, for example - PREY_LIFE_STAGE: Life stage of the prey. e.g. 'adult', 'chick', 'larva' - PREY_SAMPLE_COUNT: The number of prey individuals from which size and mass measurements were made (note: NOT the total number of individuals of this prey type, unless all individuals in the sample were measured) - PREY_SIZE_MIN: The minimum size of the prey in the sample - PREY_SIZE_MAX: The maximum size of the prey in the sample - PREY_SIZE_MEAN: The mean size of the prey in the sample - PREY_SIZE_SD: The standard deviation of the size of the prey in the sample - PREY_SIZE_UNITS: The units of size.

Many papers represent very small dietary contributions as 'trace' or sometimes 'less than 0.1%'. These have been entered as -999 - FRACTION_DIET_BY_PREY_ITEMS: The fraction (by number) of prey items that this prey type made up (e.g. if 1000 Euphausia superba were found out of a total of 2000 prey items, this value would be 0.5). Note: many papers represent very small dietary contributions as 'trace' or sometimes 'less than 0.1%'. These have been entered as -999 - FRACTION_OCCURRENCE: The number of times this prey item occurred in a predator sample, as a fraction of the number of non-empty samples (e.g. if Euphausia superba occurred in half of the non-empty stomachs examined, this value would be 0.5). Empty stomachs are ignored for the purposes of calculating fraction of occurrence. For gut content analyses (and any other study types where 'no prey' can occur in a sample), the fraction of empty stomachs is also given (using prey_name 'None' - e.g. if predator_total_count was 10 and 3 stomachs were empty, this will be 0.3). Note: many papers represent very small dietary contributions as 'trace' or sometimes 'less than 0.1%'. These have been entered as -999 - QUALITATIVE_DIETARY_IMPORTANCE: Qualitative description of the dietary importance of this prey item (e.g. from comments about certain prey in the discussion text of an article), if numeric values have not been given.

This dataset is a description of the shallow coastal marine fauna found in the Vestfold Hills and Rauer Island area, Antarctica. The results are from various surveys in this region over a 12 month period in 1981-82, and a full listing of species (with photographs) is given in the documentation. It includes benthic, pelagic and planktonic organisms of the coast as well as those that inhabit the ice-water interface.

Season whale catch records for austral summers from 1931/32 to 1979/80. Data have been aggregated into one degree cells centered on the reported position. The dataset covers five whale species - Blue, Fin, Sei, Minke and Humpback. These data have been exposed as an OBIS (Ocean Biogeographic Information System) resource via DiGIR (Distributed Generic Information Retrieval (DiGIR)).

This dataset is a census of penguin colony counts from the year 1900 in the Antarctic region. It forms part of the Inventory of Antarctic seabird breeding sites within the Antarctic and subantarctic islands. The Antarctic and subantarctic fauna database (seabirds) is a database detailing the distribution and abundance of breeding localities for Antarctic and Subantarctic seabirds. Each species' compilation was produced by members of the SCAR Bird Biology Subcommittee. This separate metadata record has been created beacause it represents only the penguin colony counts that have been published to OBIS. Note: The Year (not day or month) date is only relevent in this dataset. The positions that have been published to OBIS include latitude and longitude positions that were not included within the original dataset. The latitude and longitude positions that were not noted by the observer have been created from the locality given by the observer using the Antarctic Composite Gazetteer. Two spreadsheets are available for download, from the URL given below. The original, unmodified spreadsheet is available, as well as a corrected spreadsheet. In the corrected spreadsheet, the AADC has attempted to reconcile the poorly presented localities into a single column. It is possible that some of these localities may not be correct. The fields in this dataset are: SCAR Number Species Region Locality Longitude Latitude Number of Colonies Number of Pairs Type and accuracy of count Data Date References Remarks These data are further referenced in ANARE Research Notes 9 - see reference below.
