取樣方法

Please check the paper for more detailed information on sampling and sample preparation. All samples were taken in different stations in the Gerlache Strait, along the West Antarctic Peninsula. Most samples were hand collected by SCUBA divers between 8 and 20 m depth. They included benthic primary producers and biomass-dominant benthic macroinvertebrates belonging to various taxa and feeding guilds: sponges, bryozoa, cnidaria, mollusca, nemertea, annelida, arthropoda and echinodermata and chordata. Suspended particulate organic matter (SPOM), samples were taken using a Niskin bottle. Water was subsequently filtered (3L) on47mm diameter Whatman GF/F glass microfiber filters, and retained SPOM was kept for analysis.

方法步驟描述:

1. Sample preservation: Benthic organisms were stored in zip lock bags per taxa and grouped in large bags per station
2. Sample preparation: Samples were frozen at -26°C and shipped to the Freshwater and Oceanic Science Unit of research at the University of Liege, Belgium. They were dissected to retrieve the tissue selected for stable isotope analyses (cf. "measurementRemarks" field of the dataset), which was then dried at 50°C. Samples were then homogenised into powder prior to SIA using a mortar and a pestle or a mixer mill (MM301, Retsch, Haan, Germany) depending on toughness. Whenever necessary (cf. "preparations" field of the dataset), carbonates were removed from subsamples by exposing subsamples to 37 % hydrochloric acid vapor. Acidified subsamples were then kept at 50°C until further sample preparation.
3. Stable isotope analysis: The subsamples were then precisely weighed (ca 0.5-1 mg for small samples or 2-4 mg for bigger samples) in 4x4x5mm tin cups, water filters were put in 8x8x15mm cups because of their size. An amount equivalent to sample mass of tungsten oxide was added for each sample. Their elemental composition and their stable isotope values were analyzed with an elemental analyser coupled to a continuous-flow isotope-ratio mass spectrometer. Isotopic ratios were expressed in ‰ using the widespread δ notation (Coplen 2011) and relative to the international references Vienna Pee Dee Belemnite (for carbon), Atmospheric Air (for nitrogen) and Vienna Canyon Diablo Troilite (for sulfur). Sucrose (IAEA-C6; δ13C = -10.80 ± 0.47‰), ammonium sulfate (IAEA-N1; δ15N = 0.40 ± 0.20‰) and silver sulfide (IAEA-S1; δ34S = -0.30‰ and IAEA-S2; δ34S = 22.70 ± 0.20‰) were used as primary analytical standards for stable isotope ratios. Sulfanilic acid acid (Sigma-Aldrich; δ13C = -25.62 ± 0.36‰; δ15N = -0.13 ± 0.55‰; δ34S = 5.87 ± 0.50‰) was used as a secondary analytical standard for stable isotope ratios and as elemental standard. Standard deviations on multi-batch replicate measurements of secondary and internal laboratory standards (sea star tegument), analyzed interspersed with samples (one replicate of each standard every 15 analyses), were 0.3‰ for δ13C and δ15N and 0.5‰ for δ34S.
4. Instrumentation: Stable isotope ratio measurements were performed with a continuous-flow, elemental analysis (vario MICRO cube C-N-S elemental analyzer – Elementar Analysensysteme GMBH, Hanau, Germany), isotope ratio mass spectrometer (IsoPrime100 isotope ratio mass spectrometer – Isoprime, Cheadle, United Kingdom).
