 note = {The photosynthetic characteristics of sinking a microalgal community were studied to compare with the ice algal community in the sea ice and the phytoplankton community in the water column under the sea ice at the beginning of the light season in the first-year sea ice ecosystem on the Mackenzie Shelf, in the western Canadian Arctic. The phytoplankton community was collected using a water bottle, whereas the sinking algal community was collected using particle collectors, and the ice algal community was obtained by using an ice-core sampler from the bottom portion of ice core. Photosynthesis versus irradiance (P-E) incubation experiments were conducted on deck to obtain the initial slope (αB) and the maximum photosynthetic rate (PmB) of the three algal communities. The αB and the PmB of the light saturation curve, and chlorophyll a (Chl a) specific absorption coefficient (āph*) between the sinking microalgal community and the ice algal community were similar and were distinctly different from the phytoplankton community. The significant linear relationship between αB and PmB, which was obtained among the three groups, may suggest that a photo-acclimation strategy is common for all algal communities under the low light regime of the early season. Although the sinking algal community could be held for the entire duration of deployment at maximum, this community remained photosynthetically active once exposed to light. This response suggests that sinking algal communities can be the seed population, which results in a subsequent phytoplankton bloom under the sea ice or in a surface layer, as well as representing food for the higher trophic level consumers in the Arctic Ocean even before the receding of the sea ice., 西部カナダ北極域のマッケンジー海での一年性海氷域において、沈降微細藻類群集の光合成活性について、海氷底部に生息するアイス・アルジー群集と海水柱に生息する植物プランクトン群集との比較研究を太陽が現れる夏の開始時に行った。低照度域でのクロロフィル当たりの光合成曲線の始めの立ち上がり勾配（αB）と高照度域での最大光合成速度（PmB）との間には有意な一次関係があり、光適応戦略は夏の開始時の低照度下では３つの群集の間で同様であることが示唆された。このような観測結果は沈降微細藻類群集は海氷下でも表層でも、植物プランクトンの「種」個体群となりうる可能性を示唆するとともに、海氷が衰退する以前から北極域において、高次消費動物群の餌となる可能性を示唆した。},
