It can cope with the oscillations or meandering of the flow around the boundary of the control domain and is therefore particularly suited for tidal seas and sub-basins with strong mesoscale activity. We show however that the exposure time in a control domain <i>?</i> cannot be properly defined if <i>?</i> is part of a larger bounded system unless some removal process is taken into account. It is therefore suggested to revise and extend the definition of the exposure time by including a first order decay: “the exposure time for the rate constant <i>?</i> is the total time spent in a control domain <i>?</i> by particles subject to a first order decay with a rate constant <i>?</i>, irrespective of their possible excursions in and out the control domain”. The exposure time revised in this way is well-defined in all circumstances provided that the decay rate differs from zero but depends on the rate constant <i>?</i>. Alternatively, in order to diagnose the movement of water masses, the first order decay can be considered only outside the control domain.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"On the concept of exposure time","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Residence time; Exposure time; Tracers; Water renewal; Pollutanttransport","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2015-10-30","DateCreate":"2014-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000329149500003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.csr.2013.09.026"},"refs":null,"anarec":{"AnaID":238111,"PubliDate":2013,"Pagination":"27-36","XtraPublOfAnaID":null,"ISBN":null,"Volume":"71","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42769,"SerRR":"Continental Shelf Research.
