取樣方法

Samples of 5 zooplankton taxa including copepods and amphipods were collected at six stations (P1, P4, P5, P6, P7, NLEG3), using MIK nets (1200 μm with 500 μm cod end), Macroplankton trawl (multiple mesh sizes along the net, tapering to 8 mm at its end) and Bongo nets (64 and 180 μm). Samples were sorted into species and stage/size groups onboard the ship and immediately frozen at -80 ºC.

方法步驟描述:

  1. Fatty acids were analysed at the Alfred Wegener Institute, Bremerhaven, Germany. All samples were freeze-dried for at least 24 h prior to lipid extraction (-45 °C, 0.1 mbar). Zooplankton were homogenized mechanically using a Potter-Elvehjem homogenizer. Total lipids were extracted using a modified procedure from Folch et al. (1957) with dichloromethane/methanol (2:1, v/v). The extracted lipids were cleaned with 0.88 % potassium chloride solution and converted into fatty acid methyl esters (FAMEs) and free fatty alcohols derived from wax esters by transesterification in methanol, containing 3 % concentrated sulfuric acid, at 80 °C for 4 h. After a subsequent hexane extraction, the FAMEs and alcohols were separated split-less via gas chromatography. FAMEs were identified via standard mixtures and total lipid content was quantified with an internal standard (23:0) that was added prior to lipid extraction. Folch, J., Lees, M., and Stanley, G.H.S.
