During my stay, I am working on sampling and examining rock specimens collected from the Gakkel Ridge in the Arctic Ocean, while also engaging in research exchanges with local scientists.<\/p>\r\n<p>At my first destination, Louisiana State University, I was invited by Professor Jonathan E. Snow to deliver a talk as part of the <em>LSU Geology &amp; Geophysics Special Lecture<\/em> series. In my presentation, I introduced my previous research findings and discussed future perspectives for research on the Gakkel Ridge, sharing these topics with researchers and students at LSU.<\/p>\r\n<p><!-- \/wp:paragraph -->\r\n\r\n<!-- wp:image {\"id\":11319,\"width\":\"760px\",\"height\":\"auto\",\"linkDestination\":\"custom\",\"align\":\"center\"} --><\/p>\r\n<figure class=\"wp-block-image aligncenter is-resized\"><a href=\"https:\/\/www.arc.hokudai.ac.jp\/wp-content\/uploads\/2026\/08\/66e091bc2d19932de79e174ad215915d-scaled.jpg\"><\/a><a href=\"https:\/\/www.arc.hokudai.ac.jp\/wp-content\/uploads\/2026\/10\/with-j-snow-scaled.jpeg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.arc.hokudai.ac.jp\/wp-content\/uploads\/2026\/10\/with-j-snow-760x570.jpeg\" alt=\"\" width=\"760\" height=\"570\" class=\"alignnone size-large wp-image-11859\" \/><\/a>\r\n<figcaption class=\"wp-element-caption\">\r\n<div>Invited Lecture (with Professor Jonathan E.
