Therefore, the lagoon is assumed to be a saltwater lagoon and seasonal change of environmental conditions in the lagoon have been affected by the coastal waters of the Okhotsk Sea. Size-fractionated chlorophyll a and dissolved inorganic Nitrogen were measured in this lagoon from 2007 through 2009. The chlorophyll a was basically comprised by large-sized phytoplankton (more than 10m). However, the small-sized phytoplankton (<2 and 2-10m fraction) might be found at high concentrations after spring bloom and/or in the winter season so the influence of open-sea water might be strongly seen. It was notable that ammonium nitrogen concentration existed most in dissolved inorganic nitrogen (DIN). Especially, concentrated ammonium has been distributed in the bottom water. Ammonium was an easily assimilable nutrients for phyotoplankton which was the primary producer in the marine ecosystem. It was suggested that these changes of concentrations of size-fractionated chlorophyll a and DIN were constructed by the variation of the inflow of water mass from Okhotsk Sea, the change of the stratification and convection of the water column with the change of the temperature and the cumulus effect of semi-enclosed environment.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"2","subitem_description_type":"Other"}]},"item_1_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00009311499","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学生物産業学部アクアバイオ学科
