They may also provide favorable microclimates for associated fauna. To quantify thermal characteristics of holopelagic <i>Sargassum</i> aggregations, we evaluated thermal profiles of 50 aggregations in situ in the Sargasso Sea. Sea surface temperature (SST) in the center of aggregations was significantly higher than in nearby open water, and SST differential was independent of aggregation volume, area, and thickness. SST differential between aggregation edge and open water was smaller than those between aggregation center and aggregation edge and between aggregation center and open water. Water temperature was significantly higher inside and below aggregations compared to open water but did not vary inside aggregations with depth. Holopelagic <i>Sargassum</i> aggregations provide warmer microhabitats for associated fauna, which may benefit marine ectotherms, though temperature differentials were narrow (up to 0.7&nbsp;°C) over the range of aggregation sizes we encountered (area 0.01–15 m<sup>2</sup>). We propose a hypothetical curve describing variation in SST differential with <i>Sargassum</i> aggregation size as a prediction for future studies to evaluate across temporal and geographic ranges. Our study provides a foundation for investigating the importance of thermal microhabitats in holopelagic <i>Sargassum</i> ecosystems.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Holopelagic <i>Sargassum</i> aggregations provide warmer microhabitats for associated fauna","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-22 01:32:11.631805","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-09-18","DateCreate":"2023-09-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001115632500012","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-023-41982-w"},"refs":null,"anarec":{"AnaID":366923,"PubliDate":2023,"Pagination":"15129","XtraPublOfAnaID":null,"ISBN":null,"Volume":"13","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
