Specific Identity

AbstractFur seals were exterminated from Macquarie Island about 20 years after discovery of the island in 1810. Their specific identity is unknown. Few fur seals were reported at the island until it was occupied by the Australian National Antarctic Research Expeditions in 1948. Fur seal numbers are now increasing. An archaeological excavation at a sealers' quarters at Sandy Bay in 1988 revealed the fragmented skull of a young Antarctic fur sealArctocephalus gazella1.1 m below the surface in a layer dated in the 1870s and 1880s. This period coincides with the recovery of fur seal populations in the South Atlantic Ocean following earlier harvesting. Elsewhere it has been argued that the Antarctic fur seal is unlikely to have been the original fur seal at Macquarie Island because few individuals of that species are ashore in winter, which is the season when the island was discovered and fur-seal harvesting began. It is concluded that the Sandy Bay skull is from a vagrant animal.

ABSTRACTCaves of marine origin occur in tectonically uplifted stacks on the coastal terrace and in plateau edge cliffs at a number of locations around Macquarie Island. Some of the caves have been located and their distributions mapped. Four of the best known caves are mapped in detail. Aspects of their geology, structure and biology, including speleothem development, clastic deposits, faunal remains and subfossil deposits are explored. Many of these caves contain deposits, which may have the potential to be investigated, as beach and peat deposits have been, for dating key time periods in the island's evolution. The palaeoenvironmental research potential of the sea caves on Macquarie Island has yet to be exploited. Further knowledge about these caves will assist in the understanding of the processes that have acted on Macquarie Island and other polar and sub-polar islands.

Pup Growth

Recent investigations by members of Australian National Antarctic Research Expeditions to Macquarie I. have revealed a decrease in the elephant seal population there of approximately 50% over the last 36 years. Lower birth weights and/or slower growth during the lactation period might explain this decrease. To test this hypothesis, growth of pups was studied from birth to 20 days during the 1984 and 1985 breeding seasons; these results were compared as far as possible with similar results for the 1956 and 1965 seasons. Average birth weight has not changed significantly over the last 20 years; it is suggested that if food supply were a major factor in the reduction of the elephant seal population, then birth weights in 1985 would have been lower than those in 1956. At birth, male pups were 7% (3 kg) heavier than female pups in 1985. Results from previous years suggest that this is probably normal in this seal. The weight of pups near weaning (20 or 21 days old) is shown to be significantly less in 1984 and 1985 than 1965, but this may be explained by differences in methodology. It is concluded that, on the evidence available, the pattern of pup growth on Macquarie I. has not altered significantly with time, but more work is needed to reach a clear conclusion.

Sections of coastline of Heard and Macquarie Islands were surveyed for marine debris in the summer of 1987–88 and 1989, respectively. These surveys were carried out at the same sites as previous surveys in 1986–87 at Heard Island, and in 1988 at Macquarie Island. The minimum rate of artefact accumulation was 13 objects per km of shoreline per year for Heard Island, and 90 objects per km of shoreline per year for Macquarie Island. Drift-cards, released from known locations and collected on the two islands, show a similar artefact catchment area.Plastic litter was a major component of the debris at both islands. Fisheries-related debris accounted for 40% of all artefacts on Heard Island, compared with 29% on Macquarie Island. Entanglement of Fur Seals appears to be more common at Heard Island, while plastic ingestion by seabirds appears to be more common at Macquarie Island.

In 1949 the Australian National Antarctic Research Expeditions (ANARE) began a long-term ecological study of the Southern Elephant Seal (Mirounga leonina) at HeardIsland. The biologists devised a method of branding seals for individual recognition (Chittleborough and Ealey, 1953) which has been modified only in detail since then (Carrick and Ingham, 1962a). At Heard Island, pups were branded every year until 1953, but the study here came to an end with the closing of the ANARE station in 1955. At Macquarie Island, pups have been branded every year from 1951 to 1965, giving a sample of individuals of known age and known history.

Robertson (1959) has examined a year's (1954) records of magnetic bays in H, 1J.., Z obtained at the Australian National Antarctic Research Expedition's station at Macquarie I. (54�5� S., 15~ E.). Robertson's Table 1 contains 450 bays in H. Of these 152 are positive bays, and 298 negative. These numbers do not include 38 periods (each of greater than 4 hr duration) of overlapping bay activity or in which bay activity is obliterated by a magnetic storm.

Abstract. The Scientific Committee on Antarctic Research (SCAR) and the Scientific Committee on Oceanic Research (SCOR) jointly intend to build a Southern Ocean Observing System (SOOS). This paper addresses the required data flow infrastructure. SOOS will use a system of systems approach, using existing observation programmes and projects. Data should be submitted to professional data centres. The problem arises how to link all these data centres and get a central overview of the SOOS data as well as direct access to the data. The Netherlands National Oceanographic Data Committee (NL-NODC) has successfully built a national distributed oceanographic data acccess infrastructure, adopting and implementing technology developed by the European SeaDataNet project. The Dutch system has been operational since early 2009. The conclusion is that the SeaDataNet technology can be used to build an operational, distributed data delivery infrastructure, featuring all elements required by the Southern Ocean Observing System (SOOS).

Abstract. The distribution of dissolved N2O in the Southern Ocean at 140° E was measured during the austral summer (February–March 2002) in the framework of the 43rd Japanese Antarctic Research Expedition (JARE-43). Surface-dissolved N2O was undersaturated (about 94% saturation), and the calculated mean sea-air flux rate was −3.68±2.57 μmol m−2 d−1. The vertical distributions tested exhibited N2O maxima at around 150–300 m (ΔN2O, 7.90–8.51 nM) below the chlorophyll-rich layer, which coincided with the layer of minimum oxygen. These observations strongly suggest that N2O production and consumption are related to apparent oxygen utilization (AOU). In the deeper layer, the presence of anoxic microsites within particles, together with the horizontal and vertical movement of cold water around Antarctica, is one of the parameters that govern the intramolecular distribution of the isotopic composition of N2O. The N2O isotopic compositions in the maximum layer were +7.3 to +8.2‰ for δ15Nbulk and +43.5 to +46.2‰ for δ18O associated with the coupling of nitrification and denitrification production mechanisms. Site preference decreased from an average 17‰ at the surface to the ΔN2O maximum and slightly increased with depth up to 24‰ at the deeper region. The influence of deep Southern Ocean N2O on the global N2O budget is estimated to be about 46.2±5.3 Mg N2O-N d−1, which represents the amount that can escape to the atmosphere and thus contribute to emissions into the world's oceans.
