Metadata record for data expected from ASAC Project 1003 Further investigations of the effects of the Nella Dan oil spill on intertidal benthic communities at Macquarie Island: continued recovery of kelp holdfast communities. See the link below for public details on this project. The project investigated spatial variation in kelp holdfast macrofaunal communities 7 years after the initial oil spill. The project was expanded to cover more sites than were sampled in projects 250 (ASAC_250) and 672 (ASAC_672). Results indicated that an impact was still detectable at one of the 3 oiled sites. This dataset contains the 1988 and 1994 data. Holdfast data from the 1994/1995 season is also included (comparing east versus west). The numbers are total individuals of each species that were found in each holdfast sample. This is a basic, though standard, species-abundance matrix. The site codes used in this project are: SB = Sandy Bay SEC = Secluded Bay BB = Buckles Bay GC = Garden Cove GG = Green Gorge GB = Goat Bay HMB = Half Moon Bay BAUER = Bauer Bay Other codes as for oil spill data The first number given after the site code is the site number at that sampling location. The second number is the replicate at that site. Thus sb(1)3 is Sandy Bay site 1, replicate 3. The fields in this dataset are: Species Year Site

Metadata record for data expected from ASAC Project 250 See the link below for public details on this project. The study investigated the impacts of oiling on the biota of rocky shores. Five shore zones were evaluated and kelp holdfasts were collected (but not evaluated as part of this project). Data were collected using quadrat and line transect methods using counts and percentage cover as variables. Data for this work was also used in ASAC projects 672 and 1003 (ASAC_672, ASAC_1003). This dataset contains the 1988 data only. The site codes used in this project are: SB = Sandy Bay SEC = Secluded Bay BB = Buckles Bay GC = Garden Cove GG = Green Gorge GB = Goat Bay The first number given after the site code is the site number at that sampling location. The second number is the replicate at that site. Thus sb(1)3 is Sandy Bay site 1, replicate 3. The numbers are total individuals of each species that were found in each holdfast sample. This is a basic, though standard, species-abundance matrix. The fields in this dataset are: Species Year Site

Metadata record for data expected from ASAC Project 2163 See the link below for public details on this project. Records of observations of kelp rafts passing within 50 m of one side of the vessel over replicated periods of 1 hour. Data collected over subantarctic latitudes only. Records include: size, species, presence/absence of holdfast, latitude and longitude, ship speed.

Collections of 23 macroinvertebrate taxa associated with Durvillaea antarctica holdfasts and 58 invertebrate taxa associated with artificial substrata collectors are described from shallow-water and intertidal habitats at Heard Island. The fauna sampled possessed strong biogeographic affinities with the Kerguelen Island fauna and, to a slightly lesser extent, the fauna recorded at Macquarie Island. The fauna possessed negligible affinity with the Antarctic. Experiments involving the offshore tethering of Durvillaea antarctica holdfasts indicated epifaunal invertebrates rapidly abandoned detached holdfasts, but that the few species surviving after one day can probably survive long periods adrift. The fields in this dataset are: Taxon (species) Distribution Locality Date Control
