Marine snow also incorporates and transports marine contaminants such as microplastics and spilled oil into the ocean\u0026rsquo;s interior. During sinking through the water column, aggregates are subject to biological and physical transformation, determining the export efficiency of marine snow-associated matter. I will present results from laboratory incubations on heterotrophic microbial degradation and physical fragmentation of marine snow and marine oil snow, emphasizing the importance of small scale processes in millimeter-sized aggregates on large scale implications for the ocean\u0026rsquo;s elemental cycling.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Biological Sciences Seminar by Kai Ziervogel, Ph.D."}],"uid":"27964","created_gmt":"2020-08-20 09:01:25","changed_gmt":"2020-08-20 15:11:35","author":"Jasmine Martin","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-09-24T12:00:00-04:00","event_time_end":"2020-09-24T13:00:00-04:00","event_time_end_last":"2020-09-24T13:00:00-04:00","gmt_time_start":"2020-09-24 16:00:00","gmt_time_end":"2020-09-24 17:00:00","gmt_time_end_last":"2020-09-24 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"638122":{"id":"638122","type":"image","title":"Dr. Kai Ziervogel gives a talk titled, \u0022Microbial Processes Associated with Marine Snow: Small Scale Processes with Large Scale Implications.\u0022","body":null,"created":"1597913402","gmt_created":"2020-08-20 08:50:02","changed":"1597913402","gmt_changed":"2020-08-20 08:50:02","alt":"","file":{"fid":"242693","name":"Ziervogel_at sea.JPG","image_path":"\/sites\/default\/files\/images\/Ziervogel_at%20sea.JPG","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/Ziervogel_at%20sea.JPG","mime":"image\/jpeg","size":169579,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Ziervogel_at%20sea.JPG?itok=NUY0RH2T"}}},"media_ids":["638122"],"groups":[{"id":"1275","name":"School of Biological Sciences"}],"categories":[],"keywords":[{"id":"166882","name":"School of Biological Sciences"},{"id":"166892","name":"School of Biological Sciences Seminar"},{"id":"185626","name":"Kai Ziervogel"},{"id":"28871","name":"Joseph Montoya"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EFor additional login information contact \u003Ca href=\u0022mailto:jasmine.martin@biosci.gatech.edu?subject=Additional%20Login%20Details%20for%20Seminar\u0022\u003EJasmine Martin\u003C\/a\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
