1. Broadbandwidth total target strength measurements of Antarctic krill (Euphausia superba) from reverberation in a cavity

   Abstract:  Total scattering cross-sections (st) of Antarctic krill, Euphausia superba, were acoustically measured over a broadbandwidth (36 to 202 kHz) using a new technique [J. De Rosny and P. Roux, 2001, J. Acoust. Soc. Am. 109(6): 2587:2597]. From 18 February to 9 March 2002, mean total target

2. Reconciling theoretical versus empirical target strengths of krill; effects of phase variability on the distorted wave Born approximation

   Abstract:  A model was recently proposed to predict the target strengths (TS) of Antarctic krill, Euphausia superba, versus incidence angle (?) [McGehee et. al, 1998, Deep Sea Res. Pt2, 45(7)1273-1294]. Based on the distorted wave Born approximation (DWBA), the model depends upon the coherent

3. Antarctic fur seals in the South Shetland Islands: pup production and population trends

   Abstract:  Discovered in 1819, the South Shetland Islands soon became the focus of intensive sealing efforts. Abundant, but never quantified, Antarctic fur seal populations were exterminated by 1874 and did not begin re-colonizing until ~80yrs later. The first reported pups born post-exploitation

4. A proposal for modifications to Standard Method C2: fur seal pup growth

   Abstract:  Antarctic fur seal pup growth studies presented and reviewed by WG-EMM-01 led to discussion on the need to modify Standard Method C2: Pup growth. The issues discussed relate to the timing of sampling and the selection of animals to weigh. The following is a proposal on how the protocol

5. Foraging range and at-sea locations of female Antarctic fur seals, Cape Shirreff, Livingston Island, from 1999–2002

   Abstract:  During the breeding season, Antarctic fur seals are central-place foragers, ranging from their colony to feeding areas hours to days offshore, returning periodically to suckle. Outside of this, little is known about a female’s foraging strategy, her success upon which depends not only

6. Atlas of coastal sea ice in eastern Antarctica

   Abstract:  The attached document provides information on an atlas of sea ice produced by the n. It was compiled from AVHRR satellite imagery initially to provide information on the sea ice in the vicinity of the CCAMLR Ecosystem Monitoring Program sites at Bechervaise Island near the Australian

7. The winter distribution of Adélie and chinstrap penguins from two breeding colonies in the South Shetland Islands of Antarctica

   Abstract:  Satellite telemetry was used to determine the winter movements and distributions of five chinstrap and six Adélie penguins from two breeding colonies in the South Shetland Islands, Antarctic Peninsula region during the 2000 and 2001-2002 austral winters, respectively. Three chinstrap

8. Proposal for a new Antarctic Specially Protected Area, Terra Nova Bay, Ross Sea

   Abstract:  The Area proposed for special protection is a small and narrow strip of waters extending approximately 9.5 km in length immediately to the south of Terra Nova Bay Station and up to a maximum of 7 km from the shore. The total area of the proposed site is just under 30 km2. The boundaries

9. Management plan for Site of Special Scientific Interest No. 36 – Eastern Dallmann Bay

   Abstract:  Management at Eastern Dallmann Bay aims to: • avoid degradation of, or substantial risk to, the values of the Area by preventing unnecessary human disturbance; • allow scientific research on the marine environment while ensuring protection from oversampling; • allow other scientific
