They host chemosynthetic microbial communities which fix inorganic carbon (C) at the seafloor, as well as a wide range of macroinfauna, including vent-obligate and background non-vent taxa. There are no previous direct observations of carbon cycling at a sedimented hydrothermal vent. We conducted <span class=\"inline-formula\"><sup>13</sup>C</span> isotope tracing experiments at three sedimented sites in the Bransfield Strait, Antarctica, which showed different degrees of hydrothermalism. Two experimental treatments were applied, with <span class=\"inline-formula\"><sup>13</sup>C</span> added as either algal detritus (photosynthetic C), or as bicarbonate (substrate for benthic C fixation). Algal <span class=\"inline-formula\"><sup>13</sup>C</span> was taken up by both bacteria and metazoan macrofaunal, but its dominant fate was respiration, as observed at deeper and more food-limited sites elsewhere. Rates of <span class=\"inline-formula\"><sup>13</sup>C</span> uptake and respiration suggested that the diffuse hydrothermal site was not the hot spot of benthic C cycling that we hypothesised it would be. Fixation of inorganic C into bacterial biomass was observed at all sites, and was measurable at two out of three sites. At all sites, newly fixed C was transferred to metazoan macrofauna. Fixation rates were relatively low compared with similar experiments elsewhere; thus, C fixed at the seafloor was a minor C source for the benthic ecosystem. However, as the greatest amount of benthic C fixation occurred at the “Off Vent” (non-hydrothermal) site (<span class=\"inline-formula\">0.077±0.034</span> <span class=\"inline-formula\">mg C m<sup>−2</sup></span> fixed during 60 <span class=\"inline-formula\">h</span>), we suggest that benthic fixation of inorganic C is more widespread than previously thought, and warrants further study.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Benthic carbon fixation and cycling in diffuse hydrothermal and background sediments in the Bransfield Strait, Antarctica","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-04-08","DateCreate":"2020-04-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000505669100001","VABBcode":null,"OpenAcc":1,"DOI":"10.5194/bg-17-1-2020"},"refs":null,"anarec":{"AnaID":322780,"PubliDate":2020,"Pagination":"1-12","XtraPublOfAnaID":null,"ISBN":null,"Volume":"17","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":68092,"SerRR":"<b>Gattuso, J.P.; Kesselmeier, J.
