Métodos de Amostragem
We sampled several benthic macroalgae, in addition to pelagic particulate organic matter (POM),sediment POM, sea ice POM, and consumers from several different locations occupying the shallow, nearshore zone (0 to 30 m) around the Vestfold Hills, in the summer season from December 2009 to March 2010. Samples were collected from 20 sites visited once over the 4 mo sampling period. Consumers were collected as close to their potential food sources as recommended by Gillies et al. (2012a), with the exception of sea ice algae which was sampled prior to winter sea ice break out (midDecember) with sampling sites chosen to represent a mixture of nearshore and offshore locations. All sampling sites were within a 5 km radial distance of Davis Station, although we were careful not to sample within 500 m of the sewerage outfall to avoid potential contamination of isotope values. We aimed to collect many species across a range of feeding guilds in order to describe carbon flows and trophic pathways amongst the general benthic community.
| Área de Estudo | The Vestfold Hills lie at 68°35’S, 77°58’E in Prydz Bay, Princess Elizabeth Land. The area is bound by the Sorsdal Glacier in the south and the Antarctic Plateau 24 km to the north. The region is surrounded by low-lying rocky hills, indented by 3 large fjords and several smaller bays and inlets. A number of small, rocky islands lie in close proximity to the coast. The area supports a rich benthic community (Tucker & Burton 1987), comparable with that of similar habitats from other parts of Antarctica (Tucker & Burton 1988). Winter sea ice breaks out in late spring (November to December), with the area relatively ice free from January to March. The Windmill Islands are located at 66°17’S, 110°31’E in Wilkes Land (1000 km east of the Vestfold Hills) in close proximity to the Vanderford Glacier. Spanning an area of 30 km along the coastline, the region is characterised by 50 islands, with 5 main peninsulas jutting out from the Antarctic Plateau. The peninsulas comprise low rocky hills with intervening snow-covered valleys and meet the water’s edge with a mix of low ice edges and rocky shores. In general, patches of bedrock and boulders occur at shallow depths near the shore, with the substrate sloping down to finer grades of sediment. The benthic fauna is comparable to other nearshore locations within Antarctica (Johnston et al. 2007). Winter seaice breaks out sporadically over the summer months (December to February), leaving a mosaic of ice-free and ice-covered areas during the summer period. |

| Controle de Qualidade | The original datasheet was reformatted to fit GBIF/ IPT Biodiversity.AQ standard. The new datasheet "DavisStationStableIsotopes.csv" provides the dataset ID, event ID, recordNumber, occurrenceID, eventDate, decimalLatitude, decimalLongitude, continent, occurrenceStatus, basisOfRecord. The taxonomical organisation is provided to the lowest taxonomical rank that could be determined, after matched in WoRMS (World Register of Marine Species). |
Descrição dos passos do método:
- Sediment POM samples were collected by divers throughout the sampling period at depths of 6 to 30 m by coring (5 cm diameter by 10 cm long) and utilising only the top 1.5 cm section of the core
