プロジェクトデータ

The TANGO1&2 expedition ventured to accumulate new data on the responses of marine ecosystems to shifts in ice regimes in the West Antarctic Peninsula (WAP), taking full advantage of a nimble sampling platform, the R/V Australis, a steel hulled, fully rigged motor sailer. TANGO1 took place between February and March 2023 and 2024, sampling two main locations at different spatial scales. Deploying 14 different types of gear (both traditional and modern), The use of R/V Australis for coastal studies deemed to be extremely efficient, in terms of environmental impact and reactivity, allowing the team to adapt the sampling efforts in function of the weather or anchoring conditions. Fully devoted to the expedition, the ship allowed the Tango team to sample in shallow areas, not accessible to icebreakers and too far away from research stations, and which have been under sampled.

収集方法

Please check the paper for more detailed information on sampling and sample preparation. All samples were taken thirteen different stations along the Western Antarctic Peninsula. Most samples were hand collected by SCUBA divers between 5 and 20 meters depth. They consisted only in Sterechinus neumayeri specimens.

Method step description:

1. 1. Sample preservation: Samples of Sterechinus neumayeri were stored individually in glass vials and grouped in large bags per station
2. 2. Sample preparation: Once dissected onboard to only keep the Aristotle’s lantern with the associated muscles, samples were primarily dried at 60°C then kept frozen at -20°C, and shipped to the Freshwater and Ocean Science Unit of research at the University of Liege, Belgium. At the lab, samples were dried at 60°C or 72 hours, and homogenized into a powder prior to SIA using a mortar and pestle.
3. 3. Stable isotope analysis: For each individual, approximately 2.5 mg of homogenized muscle tissue were weighed into tin capsules. Isotopic ratios were expressed using the widespread δ notation (Coplen, 2011), in ‰ and relative to the international references Vienna Pee Dee Belemnite (for carbon), atmospheric air (for nitrogen) and Vienna Canyon Diablo Troilite (for sulphur). IAEA (International Atomic Energy Agency, Vienna, Austria) certified reference materials caffeine (IAEA-600; δ13C = −27.771 ± 0.043‰ ; δ15N = 1.0 ± 0.2‰; means ± SD), and barium sulphate (IAEA-SO-5; δ34S = 0.5 ± 0.2‰ ) were used as primary analytical standards. Sulfanilic acid (Sigma-Aldrich; δ13C = −25.6 ± 0.4‰; δ15N = −0.13 ± 0.4‰; δ34S = 5.9 ± 0.5‰; means ± SD) was used as secondary analytical standard. Standard deviations on multi-batch replicate measurements of secondary and internal lab standards (amphipod crustacean muscle) analysed interspersed with samples (one replicate of each standard every 15 analyses) were 0.2‰ for both δ13C and δ15N and 0.4‰ for δ34S.
4. 4. Instrumentation: These ratios were measured by continuous-flow elemental analysis–isotope ratio mass spectrometry (CF-EA-IRMS) at the University of Liège, using a vario MICRO Cube elemental analyser (Elementar Analysensysteme GmbH, Hanau, Germany) coupled to a precisION mass spectrometer (Elementar UK, Cheadle, UK).
