In this study we have successfully characterised the fluorescent fraction of DOM in the catchment of a Danish estuary using fluorescence excitation–emission spectroscopy and parallel factor analysis (PARAFAC). PARAFAC aids the characterisation of fluorescent DOM by decomposing the fluorescence matrices into different independent fluorescent components. The results reveal that at least five different fluorescent DOM fractions present (in significant amounts) in the catchment and that the relative composition is dependent on the source (e.g. agricultural runoff, forest soil, aquatic production). Four different allochthonous fluorescent groups and one autochthonous fluorescent group were identified. The ability to trace the different fractions of the DOM pool using this relatively cheap and fast technique represents a significant advance within the fields of aquatic ecology and chemistry, and will prove to be useful for catchment management.", "publicationTitle": "Marine Chemistry", "publisher": "", "place": "", "date": "August 2003", "volume": "82", "issue": "3–4", "section": "", "partNumber": "", "partTitle": "", "pages": "239-254", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Marine Chemistry", "DOI": "10.1016/S0304-4203(03)00072-0", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0304420303000720", "accessDate": "2013-11-13T21:01:40Z", "PMID": "", "PMCID": "", "ISSN": "0304-4203", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Coloured dissolved organic matter", "type": 1 }, { "tag": "Fluorescence", "type": 1 }, { "tag": "Mixing", "type": 1 }, { "tag": "Modelling", "type": 1 }, { "tag": "River", "type": 1 } ], "collections": [ "ZXAD8B7J" ], "relations": {}, "dateAdded": "2014-02-24T17:56:40Z", "dateModified": "2014-02-24T17:56:40Z" } }, { "key": "NDC895KZ", "version": 3, "library": { "type": "group", "id": 250691, "name": "EEM", "links": { "alternate": { "href": "https://www.zotero.org/groups/eem", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/250691/items/NDC895KZ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/eem/items/NDC895KZ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1680738, "username": "gby0", "name": "George Yasko", "links": { "alternate": { "href": "https://www.zotero.org/gby0", "type": "text/html" } } }, "creatorSummary": "Sparks", "parsedDate": "2011-01-31", "numChildren": 1 }, "data": { "key": "NDC895KZ", "version": 3, "itemType": "book", "title": "Advances in Agronomy", "creators": [ { "creatorType": "author", "firstName": "Donald L.", "lastName": "Sparks" } ], "abstractNote": "Advances in Agronomy continues to be recognized as a leading reference and a first-rate source for the latest research in agronomy.

Samples collected on trans-oceanic cruises in the Pacific and Atlantic oceans were used to investigate the optical characteristics of dissolved organic matter in waters with limited freshwater influence (salinity > 30). Parallel Factor Analysis (PARAFAC) of fluorescence spectra revealed that coastal and oceanic dissolved organic matter (DOM) fluorescence could be separated into at least eight separate components: 4–5 humic-like and 3–5 protein-like signals. Two of the humic components were identified as representing terrestrial organic matter and their signals could be traced in the open ocean (Pacific and Atlantic) at levels of approximately 1.5% of riverine concentrations. An additional humic component, traditionally identified as the “marine” or “M” peak, was found to be both sourced from land and produced in the ocean. These results demonstrate that the supply, mixing and removal of terrestrial organic matter in oceanic waters can be observed with relatively simple measurement techniques, suggesting that fluorescence spectroscopy could play a useful role in future studies of the origin and fate of DOM in oceanic environments.", "publicationTitle": "Marine Chemistry", "publisher": "", "place": "", "date": "January 1, 2008", "volume": "108", "issue": "1–2", "section": "", "partNumber": "", "partTitle": "", "pages": "40-58", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Marine Chemistry", "DOI": "10.1016/j.marchem.2007.10.003", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0304420307002356", "accessDate": "2013-11-13T21:03:03Z", "PMID": "", "PMCID": "", "ISSN": "0304-4203", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Dissolved organic matter", "type": 1 }, { "tag": "Fluorescence spectroscopyParallel Factor Analysis (PARAFAC)", "type": 1 }, { "tag": "Tracer techniques", "type": 1 } ], "collections": [ "FS2MNJTP", "ZXAD8B7J" ], "relations": {}, "dateAdded": "2014-02-24T17:56:09Z", "dateModified": "2014-02-24T17:56:09Z" } }, { "key": "TC5K6FW4", "version": 2, "library": { "type": "group", "id": 250691, "name": "EEM", "links": { "alternate": { "href": "https://www.zotero.org/groups/eem", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/250691/items/TC5K6FW4", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/eem/items/TC5K6FW4", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1680738, "username": "gby0", "name": "George Yasko", "links": { "alternate": { "href": "https://www.zotero.org/gby0", "type": "text/html" } } }, "creatorSummary": "Wiegner et al.", "parsedDate": "2009-10-01", "numChildren": 0 }, "data": { "key": "TC5K6FW4", "version": 2, "itemType": "webpage", "title": "Contribution of dissolved organic C to stream metabolism: a mesocosm study using 13C-enriched tree-tissue leachate", "creators": [ { "creatorType": "author", "firstName": "Tracy N.", "lastName": "Wiegner" }, { "creatorType": "author", "firstName": "Louis A.", "lastName": "Kaplan" }, { "creatorType": "author", "firstName": "J.

The EEM plots show at least four spectral features whose corresponding Ex/Em pairs relate to the α′, α, β and γ (or δ) fluorophores previously found in natural waters spectra. The α′ and α peaks, which identify typical humic-like components, are present in all samples, independently of the organic matter (OM) source. In FA, their Ex/Em pairs are ∼260 nm/460 nm and ∼310 nm/440 nm, respectively. In HA their excitation and emission maxima are red-shifted, the corresponding Ex/Em pairs being located at ∼265 nm/525 nm and ∼360 nm/520 nm, respectively. The appearance of β and γ (or δ) peaks is dependent both on the OM origin and on HS aging. The former (Ex/Em ∼ 320 nm/430 nm), that has been associated with the incidence of marine humic-like material, is present only in a few marine and estuarine HA. It emerges as a shoulder on the α peak and its detection is dependent on a balance between its magnitude and the magnitude and emission maxima location of the α peak. The γ (or δ) peak (Ex/Em ∼ 275 nm/315 nm in FA, and ∼275 nm/330 nm in HA), on the other hand, is better visualized in FA than in HA diagrams. It has typical protein-, mainly tryptophan-like, fluorescence properties and appears with varied significance in a few marine and estuarine samples being hardly detected in samples from exclusively terrestrial environments. It is also shown in this study that with selected λex, λem and Δλ values, regular emission, excitation and synchronous spectra can, together, provide a good picture of the OM sources and aging for extracted HS.", "publicationTitle": "Chemosphere", "publisher": "", "place": "", "date": "February 2005", "volume": "58", "issue": "6", "section": "", "partNumber": "", "partTitle": "", "pages": "715-733", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Chemosphere", "DOI": "10.1016/j.chemosphere.2004.09.038", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0045653504008185", "accessDate": "2013-11-13T20:39:44Z", "PMID": "", "PMCID": "", "ISSN": "0045-6535", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "FS2MNJTP" ], "relations": {}, "dateAdded": "2014-02-24T17:56:09Z", "dateModified": "2014-02-24T17:56:09Z" } } ]
