說明
Short-term sediment traps were deployed at 3 stations on the West Greenland continental shelf in the Davis Strait. The deployments lasted for 18.7-24.4 hours and 100 mL subsamples were collected from the sediment trap cylinders (KC Denmark style with 72 mm inner diameter) deployed at the sampling depths 20, 30, 50, 90, and 120 m. The phytoplankton samples were preserved with 2 mL acidic Lugol solution, stored cool (+4 C) and in darkness, until the microscopical analysis. Since the sediment trap cylinders were not prefilled with filtered sea water, a minor overestimation of the downward flux cannot be excluded. From this field campaign, also the cruise report is publicly available on Zenodo (https://zenodo.org/doi/10.5281/zenodo.5913276). In addition, the following data sets are available: 1) the concentration of suspended chlorophyll a and phaeophytin (>0.7 and >10 micrometre) as well as particulate organic carbon (POC) and nitrogen (PON) in the water column (https://doi.org/10.11582/2024.00039), 2) the downward flux of Chl a, Phaeo, POC, PON at three stations (https://doi.org/10.11582/2024.00041), and 3) the protist composition in the water column (https://doi.org/10.15468/sfxd3c).

計畫資料
Data were collected as part of the project "Investigating ecosystem tipping points and cascades in the Arctic Seas" (ECOTIP). ECOTIP operates at the important link between the physical and biological systems, where a regional change in the hydrography of the Arctic Ocean might trigger a biological change at the base of the marine food web with cascading effects both on the regional and local socio-economic systems through fisheries, and on the global climate through carbon sequestration. ECOTIP is attempting to anticipate and predict these changes.

取樣方法
Gimballed frames with 2-4 transparent plexiglass sediment trap cylinders were attached to the sediment trap array at 5 sampling depths (20, 30, 50, 90, and 120 m). The trap cylinders (KC Denmark, inner diameter 72 mm) were not prefilled with filtered sea water. After recovery of the sediment trap array, the water from the trap cylinders deployed at the same sampling depth was transferred in one carboy. From this carboy, a subsample of 100 mL was taken and preserved with 2 mL of acidic Lugol solution. The sample was stored cool (+4 C) and in darkness until further analysis ashore.
| 研究範圍 | At three stations on the West Greenland continental shelf, a bottom-moored short-term sediment trap array. |

方法步驟描述:
- The microscopic analysis was later conducted at the Institute of Oceanology of the Polish Academy of Sciences (IO PAN) in Sopot, Poland and the phytoplankton taxa were identified to the lowest possible taxonomic level.
