- ~5m sediment sample from the seafloor was obtained with the help of gravity coring. We quickly cleaned the corer, cut the sample into 1m sections and carefully named them. From a quick spot analysis, chief scientist and cruise leader Andreia Plaza Faverola<\/a> pointed out the dark spots could indicate organic matter (Fig. 1)<\/li>\n
- Multibeam echosounder survey was performed to obtain seafloor bathymetry and gas flares information. With the help of Researcher Sunil Vadakkepuliyambatta<\/a> and PhD Candidate Przemyslaw Domel<\/a>, I cleaned the raw data and obtained gas flare locations and flare heights (Fig. 2). I also worked on removing spurious data points from the bathymetry. Sort of like give haircut to sophisticated data.<\/li>\n<\/ul>\n
The next tasks involve performing heat probe experiments and piezometers tests. Onwards we go.<\/p>\n

For much of my short research career, I have spent time only in front of a computer and working with synthetic data. So, I was excited to be part of a research expedition into the Arctic ocean to obtain information on site. The goal is to better understand the tectonic impact on seepage systems in … Continue reading Things I am learning from my first Research Expedition on a ship<\/span><\/a><\/p>\n","protected":false},"author":997,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-173","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/posts\/173","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/users\/997"}],"replies":[{"embeddable":true,"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/comments?post=173"}],"version-history":[{"count":3,"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/posts\/173\/revisions"}],"predecessor-version":[{"id":178,"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/posts\/173\/revisions\/178"}],"wp:attachment":[{"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/media?parent=173"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/categories?post=173"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/site.uit.no\/seamstress\/wp-json\/wp\/v2\/tags?post=173"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
