All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Metadata record for data from ASAC Project 1174

---- Public Summary from Project ----
Australia's World Heritage listed subantarctic Heard and McDonald Islands are experiencing rapid climate change. Their terrestrial and coastal ecosystems are poorly known. This multidisciplinary project will gather baseline data on ecosystem biodiversity and species distribution, and make predictions about responses to future environmental change, providing vital information for conservation protocols.

From the abstract of the referenced paper:

During an early summer visit in 2000, mosses were collected from sites around Heard Island. Three species, Bryoerythrophyllum recurvirostrum, Philonotis cf. tenuis and Syntrichia filaris have been added to the list of moss species known from the island, bringing the total to 40 moss taxa. Syntrichia anderssonii was found with sporophytes, whereas previously its sporophytes were known in the subantarctic only from Macquarie Island. Extensions of range on Heard Island have been recorded for several species. There are few geographical differences in species composition between locations around the island, provided appropriate habitats exist.

Field collections
During a three week visit to Heard Island in October and November 2000 as part of the Australian Antarctic Program, collections were made at 24 sites around the island. Helicopter support allowed access to a variety of locations including several sites isolated by glaciers and not accessible on foot. However, because of constraints of weather and helicopter availability, the time available at many sites was short and resulted in greatly varying times for searching and collecting. Our visit to Heard Island preceded the spring thaw and at many sites vegetation was snow covered, so that collections of bryophytes could only be made after digging through snow and ice. Collections were, as a result, somewhat random and far from complete at some locations, although nevertheless valuable since there have been few previous collections of bryophytes from Heard Island, and none at all from some of the sites that were visited. Specimens were placed into plastic bags in the field, stored at ambient temperature (below 0 degrees C) on Heard Island, and subsequently air dried and stored in paper envelopes. They have been identified at Macquarie University, and voucher specimens have been lodged with the National Herbarium of New South Wales at the Royal Botanic Gardens, Sydney (NSW). Specimens collected by D. Bergstrom on a previous expedition in 1987 have not been re-examined, but comparisons have been made with published data (Bergstrom and Seppelt 1988, Bergstrom and Selkirk 1997) in order to provide additional information on species distribution.
