Also, a detailed microscopic study was made for microalgae and cyanobacteria. A suite of n-alkanes and n-alkenes in carbon chain length ranging from nC_<13> to nC_<35> were found in concentrations changing from 13 to 2200 and 1.1 to 5000ng/g of dry soil, respectively, varying largely among the samples. Normal alkene/n-alkane ratios ranged from 0.085 to 2.4. Surprisingly, the major hydrocarbons were all oddcarbon numbered long-chain n-alkanes (≧C_<20>), maximum nC_<23 : 0> (carbon chain length : number of double bonds), nC_<25 : 0> or nC_<27 : 0> and/or n-alkenes, maximum nC_<23 : 1>, nC_<25 : 1> or nC_<29 : 2>. The odd/even carbon ratios for n-alkanes and n-alkenes were all much greater than unity. For the possible sources of these unusual hydrocarbons, mosses, insects, aeolian transport of the waxes of vascular plants from the mid and lower latitudes, erosion of sedimentary rocks, and microorganisms, such as bacteria, fungi, cyanobacteria and microalgae were considered. No evidence of mosses and insects was found in the studied sites. Also, the microscopic study revealed that living cells were rare and no green algae were detected, but the colonial envelopes of Anacystis-and Nostoc-type cyanobacteria were found in some soil samples. The hydrocarbon composition was much different from airborne vascular plant waxes. Consequently, these hydrocarbons may have resulted from the erosion of sedimentary rocks and due to the accumulation of in situ long-term microbial activity.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002608","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1072335X","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Chemistry, College of Arts and Sciences, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Education, Shimane University"},{"subitem_text_language":"en","subitem_text_value":"Department of Chemistry, College of Arts and Sciences, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Japan Polar Research Association"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1989-09-01"}],"displaytype":"detail","filename":"KJ00002368198.pdf","filesize":[{"value":"82.1 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368198","url":"https://nipr.repo.nii.ac.jp/record/2608/files/KJ00002368198.pdf"},"version_id":"20928565-5e07-4529-a80c-0d73fc5d59a9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"THE FEATURES OF HYDROCARBONS IN THE MCMURDO DRY VALLEYS SOIL, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"THE FEATURES OF HYDROCARBONS IN THE MCMURDO DRY VALLEYS SOIL, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["417"],"pubdate":{"attribute_name":"公開日","attribute_value":"1989-09-01"},"publish_date":"1989-09-01","publish_status":"0","recid":"2608","relation_version_is_last":true,"title":["THE FEATURES OF HYDROCARBONS IN THE MCMURDO DRY VALLEYS SOIL, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:44:48.133726+00:00"}
