It is not known how much plastic debris actually \ufb02oats at the ocean surface, what mechanisms control plastic transport and fate from land to the deep sea, and what ecological impact this may have. The HOTMIC project seeks to address these knowledge gaps by focusing on a model land-ocean linkage between western Europe and the North Atlantic ocean gyre. The objective of HOTMIC is to map the distribution of MP, including particles &lt; 10\u00b5m and micro\ufb01bers, in water, sediment, and biota from coastal ocean to open ocean gyre to deep sea. This project will quantify processes controlling lateral and vertical transport of MP, including biofouling, (bio)aggregation, and deposition, for incorporation into global ocean models. To understand MP fate in the ocean, HOTMIC will examine microplastic weathering signatures during ocean transport, and evaluate the predominant mechanisms that create the weathering signature, including biological e\ufb00ects of bioshredding and ingestion. These objectives will be supported by a diverse suite of analytical techniques. In order to achieve comprehensive detection of MP particles &lt; 10 \u00b5m and micro\ufb01bers, HOTMIC will develop and optimize novel analytical methods based on a combination of non-destructive (Raman &amp; FT-IR spectrometry, microscopy), and destructive techniques (hydrolytic depolymerization, HPLC, Py-GC\/MS, EGA\/MS). In addition, HOTMIC will develop Raman spectroscopy techniques for automated detection of MP incl. particles &lt; 10 \u03bcm and micro\ufb01bers to greatly increase sample throughput, and 2D and 3D imaging of MP in biota. HOTMIC will use \ufb01eld and experimental measurements to understand transport and fate of small MP and micro\ufb01bers, and to evaluate the risks of these contaminants for marine environments and organisms.<\/p>\n\n\n\n<p><strong>The HOTMIC consortium is: <\/strong><br>GEOMAR Helmholtz-Centre for Ocean Research Kiel<br> Institute of Hydrochemistry (IWC), Technical University of Munich (TUM) <br> University of Southern Denmark<br> Instituto Portugu\u00eas do Mar e da Atmosfera<br> MARE \u2013 Marine and Environmental Sciences Centre<br> Universit\u00e0 di Pisa<br> Ghent University<br> University of Tartu<\/p>\n\n\n\n<p><strong>Contact:<\/strong><\/p>\n\n\n\n<p>Dr Mark Lenz (Coordinator)<br>GEOMAR Helmholtz Centre for Ocean Research Kiel<br>D\u00fcsternbrooker Weg 20<br>24105 Kiel<br>GERMANY<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is the blog of the JPI Oceans project HOTMIC \u2013 Horizontal and vertical oceanic distribution, transport, and impact of microplastics Project Summary: Less than approximately 10% of the plastic entering the ocean can currently be accounted for, likely due to fragmentation into small microplastics (MP) unquanti\ufb01ed by modern techniques or export from the surface [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":["post-2","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/pages\/2","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/comments?post=2"}],"version-history":[{"count":3,"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/pages\/2\/revisions"}],"predecessor-version":[{"id":15,"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/pages\/2\/revisions\/15"}],"wp:attachment":[{"href":"https:\/\/www.oceanblogs.org\/hotmic\/wp-json\/wp\/v2\/media?parent=2"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
