Leopard and Weddell seal program

2000/2001 season

31 quad based surveys were conducted along the pack-ice edge to identify where leopard seals could be accessed. 31 one hour aerial surveys were also conducted to identify the position and number of seals in the region. 36 boat based surveys were conducted to identify the size and sex of leopard seals, whether they were a resight and the possibility of sedating seals. There were a total of 23 leopard seal captures. Resights from the 1999/2000 season were made of 5 known seals. Samples were collected from a total of 19 known and 20 unknown leopards seals. Samples were also collected from 14 known weddell seals. All blood, fur, whisker, scat, and morphmetric measurements were collected. Three satellite tracking units were deployed following the moult on adult leopard seals, and one crittercam unit. 14 blood samples were taken from leopard seals, 13 blood samples from weddell seals. 6 blubber samples from leopard seals, 17 fur samples from leopard seals and 7 whiskers from leopard seals and 2 from weddell seals 32 scats from leopard seals, 50 urine and 30 scat samples from weddell seals. Voucher samples for stable isotope analysis from 2 weddell seals, 26 penguins and 64 fish were collected.


Spatial movements and haul out data from 11 leopard seals has been analysed. The blood, skin muscle, whisker, fat and fur has been prepared for later analysis. 42 separate scats have been analysed to determine diet composition. The captive feeding trials have been performed using two captive leopard seals. For each seal the following tests have been conducted, biochemical analysis of fresh serum, manual packed cell volme and white cell counts and differential white cell counts from blood smears and all haematological analysis. The refinement of the anaesthetic protocol of Zolazepam/ Tiletamine in leopard seals has been continued and this combination appears to provide a deeper and more reliable level of immobilisation compared with other anaesthetic combinations to date.


2001/2002 season

In the Prydz Bay area, 28 one-hour aerial surveys were conducted by Squirrel helicopter, 23 quad based surveys and 12 boat based surveys were conducted between latitudes 68 degrees 20'S and 68 degrees 40'S along the fast ice edge to identify the position and number of leopard seals in the region. 110 leopard seals were sighted overall and of those 5 were positively identified as resight animals, tagged during previous seasons. Five leopard seal capture procedures were performed and postmortem samples, blood fur, blubber, skin, whiskers, scats, urine and morphometric measurements were collected from two leopard seals. 6 urine and 15 scat samples collected from known and unknown leopard seals and 7 fur samples including 2 from resight animals tagged during the previous two seasons. Three Weddell seal capture procedures were performed and blood samples were collected from each seal. 125 weddell seal urine and 112 weddell seal scat samples were also collected. For stable isotope and signature fatty acid analysis, the following samples were collected as voucher samples; 1 weddell seal muscle sample, 3 adelie penguin muscle samples, 1 elephant seal whisker, muscle and skin sample, 73 Antarctic cod muscle samples, 23 ice fish and 20 krill.


Foraging Information

Scats collected from 20 seals and will be analysed for diet information.


Stable isotope analysis involved fur, blood and whiskers collected from 35 animals. A key to the stable isotopes is provided in the download file. Fatty acid analysis involved collection of blubber from 35 animals.


The fields in this dataset are:

Spatial Data

Statement
2018-08-28 - Original datasheets were reformatted to fit OBIS/GBIF/IPT Biodiversity.AQ standard. The new datasheet "leopard_weddell_seals.csv" contains information from original datasheets and complemented with information from the literature associated to the project. Also it provides the dataset ID, occurrenceID, footprintWKT, eventDate, water body, maximumDephInMeters, sampling protocol, preparations, occurrencestatus, basisOfRecord, and otherCatalogNumbers. Taxonomical organization to the lowest taxonomical rank that could be determined, after matched in WoRMS (World Register of Marine Species).
