May-98 (n = 1 for each region, Olli et al. 2002), Arctic Ocean, Aug-01 (n = 6,Olliet al. 2007), Ross Sea, December-95/January-96 (n = 5, Gowing et al. 2001), Lazarev Sea, December-95/January-95 (n = 6,Pakhomovet al. 2002). The number of samplings averaged in each region is given in parenthesis after each station name. For further information on geographical position and sampling dates, see Table 1. Data are obtained through microscopic examination of short-term sediment trap material, and conversion to carbon
