  • This document describes the deployment of five Ice Mass Balance Buoys (IMBs) and two automatic weather stations. These were primarily deployed on floes 2012103 and 20121029, as well as on helicopter flights (refer to buoy metadata for these). IMBs are labelled WHOI-1 to WHOI-6. WHOI-1 was not deployed and WHOI-3 and WHOI-5 failed and were recovered. TAS-2 was exchanged for WHOI-1 Deployments (successful): TAS-2 deployed on helo flight 20 km from ship WHOI-4 deployed on helo flight 20 km from ship WHOI-6 Deployed next to AWS-1 on ice station 1013 on 11/04 WHOI-2 Deployed next to AWS-2 on ice station 1029 on 11/01 Each AWS record air temp, relative humidity, wind speed and direction, total incident short wave, snow depth, GPS position and snow particles near ground level and at about 1m height. AWS-1 deployed on 1013 AWS-2 deployed on 1029 IMBs record GPS position and temperature in air,snow,ice, and ocean. Sensors also have a heating mode that permit determination of media they are embedded in so that snow and ice thickness can be determined. REFER TO MAKSYM LOGBOOK SCANS FOR MORE DETAILS

  • AM01 borehole drilled January 2002. Samples collected during drilling and scientific sampling phases of work. AWS continuing to operate.

  • Note - these data should be used with caution. The chief investigator for the dataset has indicated that a better quality dataset exists, but the AADC have been unable to attain it for archive. Matlab files containing raw data collected using the program "HC2S3snowwind.CR1" running on Campbell Scientific CR1000 dataloggers. Datalogger "C" was used during all ice stations. On the 8th of October a second mast and logger ("A") were installed on what became the final day of Ice Station 4, and both loggers were deployed at stations 6 and 7, with "C" containing the longer records for each station as it was always installed first and (conditions permitting) left out longer. The sensors on these masts consist of: RM Young "Wind Sentry" Vane and Anemometer set (on top of each mast), no serial numbers Rotronics HC2S3 temperature and relative humidity sensors with standard polyethylene filters Upper sensor, mast "C": s/n 60837541 Lower sensor, mast "C": s/n 60837536 Upper sensor, mast "A": s/n 60837468 Lower sensor, mast "A": s/n 60834204 RM Young "Wind Sentry" anemometers (without vane) at 3 additional elevations on each mast Wenglor YHO3NCT8 photoelectric sensors at 4 heights on each mast. The upper sensor and the third sensor from the top were oriented facing up, while the others faced down. The upper three sensors were purchased in 2012, from a batch of these sensors manufactured in a new Eastern European factory while the lowest sensor on each mast came from a lot purchased in 2007, manufactured in Wenglor's German factory and extensively tested for use in snow. Data contained in these .mat files includes the following variables, with units: Textdates: CSI formatted dates, UTC except for station 2, which was (accidentally) UTC+12 Datenm: Matlab "datenumber", all UTC except for station 2, which is also UTC+12 hours. Battvolt: battery voltage Wptemp: temperature of the Wiring Panel thermister, degrees C Temp 1: air temperature above approximately 50cm, ventilated HC2S3 rotronics sensor, degrees C RH1: relative humidity (WRT water) above approximately 50cm, ventilated HC2S3 rotronics sensor, % Temp 2: air temperature above approximately 200cm, ventilated HC2S3 rotronics sensor, degrees C RH2: relative humidity (WRT water) above 197cm, ventilated HC2S3 rotronics sensor, % Snow1: snow particles per 10second interval at approximately 10cm Snow2: snow particles per 10second interval at approximately 50cm Snow3: snow particles per 10second interval at approximately 100cm Snow4: snow particles per 10second interval at approximately 200cm Wind1: average speed (m/s) at approximately 250cm during 10s interval Wind1max: maximum speed at approximately 250cm during 10s interval Wind2: average speed (m/s) at approximately 100cm during 10s interval Wind2max: maximum speed at approximately 100cm during 10s interval Wind3: average speed (m/s) at approximately 120cm during 10s interval Wind3max: maximum speed at approximately 120cm during 10s interval Wind4: average speed (m/s) at approximately 50cm during 10s interval Wind4max: maximum speed at approximately 50cm during 10s interval WindDir: wind direction at approximately 250cm, degrees, relative to mast orientation (needs correction to true) Measurement heights varied by ice station and by mast being used.

  • Ship-based observations of whales sightings from the original 'ANARE Whale Log' books have been recovered into a single repository of sightings. ANARE (Australian National Antarctic Research Expeditions) is the historic acronym for these voyages. Currently there are data from 4 voyages, from the 1990's. Further data will be entered from existing Whale log datasheets on an ongoing basis. Observing platforms currently only include the ship, Aurora Australis. The quality and quantity of abiotic data associated with observations such as air temperature, sea ice cover etc vary immensely from voyage to voyage. Where possible these data have been entered. This dataset contains no information on estimates of survey effort and cannot be used to derive useful presence/absence spatial coverages of species during this period. It is purely sighting data only. Species distribution data are made available to SCAR-MarBIN (http://www.scarmarbin.be), OBIS and GBIF via the DiGIR protocol and Darwin Core schema.

  • AM01b borehole site Samples collected during drilling and scientific sampling phases of work. AWS continuing to operate (not a new station, but ongoing AM01 station).

  • The Antarctic Sea ice Processes and Climate [ASPeCt] data sets submitted here have been collected systematically from the bridge of an icebreaker, while it transited through the pack ice. Quantifiable observations of sea ice thickness and related characteristics of the sea ice, snow, ocean and surface atmosphere are recorded hourly while the vessel moves through the sea ice. If the vessel is stopped or has not moved at least 6nm since the previous observation, no observation will be conducted. The observation protocol has been endorsed by the Scientific Commission for Antarctic Research (under their ASPeCt programme) as the preferred method for conducting ship-based observations of sea-ice characteristics.

  • Report of the 1985 A.N.A.R.E to Heard Island. This document contains the following scientific reports: Zoology - elephant seals, fur seals, General Zoology - leopard seals, fish, insects, birds; Botany - lant communities, lichens and mosses; Limnology - Zooplankton and phytoplankton; Earth Sciences - meteorology, geomagnetism, glaciology, general mapping, general phenomena; Miscellaneous Collections; History; Environmental Impact Assessment; Site Clean up; Building report and Camp inventory; Logistics; Field Operations; Recommendations; Bibliography; Appendix. Taken from the report: The 1985 ANARE to Heard island was of greater duration than any since 1963, although brief stopovers have been made by other ANAREs more recently. It was also the first time since the 1950s that biological research was the major scientific endeavour of two ANARE parties working simultaneously at both ends of the island. This reflects renewed interest in The Territory of Heard Island and The McDonald Islands and its surrounding Exclusive Economic Zone, which has a significant fishery potential. As studies on the population of the Island's Elephant Seals may offer methods of monitoring major changes in the relative balance of high level consumers in the marine ecosystem (See below), the expedition had as its highest priority the thorough censusing of Elephant Seals on the Island over the pupping period, as part of an international program aimed at monitoring the total population of these seals. A census of the whole island, by counting seals hauled out on beaches, necessitated two parties; one at Atlas Cove and the other at Spit Bay. The expedition was also given the tasks of carrying out a limited clean up of the old Atlas Cove camp (following an explicit brief which recognised its heritage value), of making a site survey for the proposed camp, and of producing an Environmental Impact Assessment of the proposed site. Other tasks included the deployment of magnetometers and the regular measurement of absolute magnetic values, a comparative meteorological program at either end of the island, an assessment of seal blubber by ultrasound, a collection of Elephant Seal blood samples for electrophoretic analysis, a Fur Seal census, a botanical survey and a general biology program made up of many small sections.

  • 1992 Wintering Field Season at Heard Island. Taken from the report: Genesis of the Expedition The concept of the 1992 expedition arose from the need to gain access to animals at Heard Island for research at precise times of the year to deploy and retrieve time-depth recorders. An Antarctic Science Advisory Committee workshop on the Southern Ocean Ecosystem was held on 10-11 September 1989 to discuss future plans for ANARE areas of operation. The workshop was attended by myself (KG - Ken Green) and Harry Burton (HRB) for the Land-based Biology section. It became apparent that the two consecutive summers needed to deploy and retrieve the recorders (one leaving Heard Island in the autumn, the next arriving early in the spring) could not be accommodated in the planning process because of planned commitments in the eastern sector of the Australian Antarctic Territory. The suggestion was therefore made by us that if two summers were impossible then perhaps the best solution was a wintering party. A memo to this effect was drafted by us and submitted on 26 September 1989. This was considered at a Heard Island Committee meeting on 18 October 1989 when changes to the shipping program were suggested that would allow two consecutive summers on Heard Island and it was concluded that "this arrangement should.....negate the need for a wintering program in the near future". The suggested rearrangement did not fully match the times required and the Land-based Biology section was loathe to deploy equipment in one summer without guaranteed access to the animals in the following spring. It was felt that this could only be assured if the biologists were on the island through the whole period. An additional advantage was that dietary studies of the main fish predators could be continued throughout the winter period. To this effect the proposal for a wintering party was re-submitted on 26 February 1990 with the suggested personnel being three biologists and three people in support. The proposal was re-submitted in more detail on 4 May 1990 and was examined by the ANARE Annual Planning Committee who referred it to the Assistant Director (Science) to "examine the options for conduct of this program and that following this the Heard Island Planning Committee and to the Assistant Director (Science) who was requested to prepare a paper for distribution to committee members for consideration at a meeting to be held on 17 July 1990. At this point the maiden voyage of the Aurora Australis took place with one aim being to deploy a party of four on Heard Island for a period of one month to undertake research into seals and penguins. This party included two of the subsequent wintering party (see Green 1990). This expedition returned in time for the Heard Island Planning Committee meeting which was held to hear reports on the 1990 expedition and to consider the proposals for 1993. A reduced complement of four expeditioners was suggested in a proposal appearing under the signature of the acting Assistant Director (Science). The committee voted to forward the proposal to the ANARE Annual Planning Committee on 26 July 1990 with the suggested alteration in timing so that the wintering expedition occurred in 1992 rather than 1993 to avoid clashing with science requirements for the Lambert Traverse. The ANARE Annual Planning Committee referred the matter to the executive and on 27 August 1990 the Heard Island Planning Committee agreed to "support a limited winter program on Heard Island in 1992 on the condition that it is to be a purely land-based exercise with work restricted to the Spit Bay area" with "a final decision on the conduct of a Heard Island wintering program (to) be made by the Executive in the near future.". Approval was given at the Heard Island Committee meeting of 24 September 1990, subject to approval by the Antarctic Research Evaluation Group (AREG) of the major programs suggested by the Land-based Biology section. At the Heard Island Planning Committee meeting of 12 December 1990 it was confirmed that AREG had provisionally approved the Land-based Biology programs and that the Executive "have supported the program subject to ASAC endorsement of the three proposals put forward." At this stage the Heard Island expedition was expected to proceed on that basis with additional programs to be considered by AREG. From this point the expedition had sufficient momentum to keep going and subsequent meetings of the Heard Island Committee dealt mainly with questions of logistics, infrastructure and procedures (these are covered in Antarctic Division file number 89/754). The final composition of the personnel for the party was not settled until 14 October 1991. The expedition sailed from Hobart on 8 January 1992 on board the Aurora Australis. Assessments of the possibility of landing by zodiac at Spit Bay were made on 24 and 28 January and on 28 January the party was deployed at Atlas Cove using three inflatable rubber boats. For a narrative of the expedition see the Log (later in the report). Scientific Background A commercial Soviet fishery has existed in the Iles Kerguelen region from the early 1970s and catches averaged about 20,000 tonnes per year between 1979 and 1986, dropping to 7886 tonnes in 1987 and 773 tonnes in 1988. Before 1978, the benthic species Notothenia rossi and N. squamifrons were mainstay of this fishery. The icefish, Champsocephalus gunnari increased in importance after that to constitute the majority of the catch. There has been little commercial fishing around Heard Island, and none since a 200 nautical mile Australian Fishing Zone (AFZ) was declared in 1979 (Williams and Ensor 1988). Catches of icefish by the Soviet research vessel RV Professor Mesyatsev on banks to the north-east of Heard Island indicated concentrations of this species in commercial interest, but other species, including benthic fishes also occurring in the diet of the seals, are not sufficiently abundant for commercial interest at this time (Williams and Ensor 1988). Results from the 1987/88 Heard Island ANARE suggested that there was a potential for competition between the increasing numbers of Antarctic Fur Seals and any future commercial fishery (Green et al 1990). Winter data were, however, lacking. In 1990 the first ANARE expedition to be present on the island into the winter period since the 1954 wintering expedition took place, with the main program being an attempt to examine the winter diet and feeding areas of Antarctic Fur Seals. Subsequent assessment of the diet of Southern Elephant Seals comparing Macquarie and Heard Islands (Green and Burton in press) also showed this species to be a potential competitor, both with Antarctic Fur Seals and with a potential fishery. Bearing in mind the possibility that a request for commercial fishing rights within the Heard Island AFZ might be made in the foreseeable future, probably as an adjunct to the Kerguelen or Antarctic fishery rather than a new venture, a full assessment of the role of fish predators was indicated. The analysis of a potential interaction between wildlife and fisheries depends on the collection of three primary sets of data: the availability of commercial fish species, the diet of the predator, and the spatial overlap in the demands of the two competing interests. The aim of the 1992 ANARE was therefore to collect all of these data. The Marine Science cruises to the area collected data on fish location and relative abundance, continuing the work of previous voyages such as Professor Mesyatsev and the Aurora Australis on its maiden voyage. The work of the shore party would be to investigate the diet of fish predators through scat collections and examination of stomach contents. The main objectives of the 1992 ANARE program on Heard Island were therefore to collect data on the feeding ecology of the major warm-blooded predators of fish in the Heard Island region (excluding whales), to provide baseline data in their ecology in the absence of a nearby fishery, and to provide an estimate of the degree of interaction between these animals and a potential fishery. This was considered to be a major scientific program, both in resources and time and was expected to net valuable scientific information from a very small deployment of personnel. In addition to the main objectives, a number of additional research programs were to be conducted by the wintering party including meteorological observations, glaciology, coastal erosion surveys and marine debris surveys.
