Sampling was performed at the ocean sampling site ”the yellow bouy” (Lat: 58°15’41’’N, Long: 11°27’11’’E) at 13:00 o´clock during the summer solstice 2012‐06‐20. Water was collected from a depth of 1 meter using a water sampler. Water samples were transported to the lab in 4 x 1.3 liter acid cleaned plastic bottles on ice in a thermos within 10 minutes and then filtered instantly.
(1) 1120, (2)1195 ml , (3) 1180 and (4) 1090 ml water , respectively was run through each of four 0.22 μm Sterivex filters (Millipore). Filtering times were (1) 60 , (2) 65, (3) 68 and (4) 80 min, respectively. Filters were sealed and immediately frozen at ‐80 °C in individual zip‐lock bags. The filters was beige to light brown after the filtering process.
