An analysis of multi-satellite derived products of four major phytoplankton functional types (PFTs \u2013 diatoms, haptophytes, prokaryotes and dinoflagellates), was carried out to investigate the PFT time series in the trans-Atlantic Ocean between 2002 and 2021. The investigation includes the two-decade trends, climatology, phenology and anomaly of PFTs for the whole Atlantic Ocean and its different biogeochemical provinces in the surface layer that optical satellite signals can reach. The PFT time series over the whole Atlantic region showed mostly no clear trend over the last two decades, except for a small decline (-0.001 mg m-3 per year) in prokaryotes and an abrupt increase in diatoms during 2018\u20132019 which is mainly observed in northern Longhurst provinces. The phenology of diatoms, haptophytes and dinoflagellates are very similar: in the higher latitudes bloom maxima are reached in spring (April in the northern and October in the southern hemisphere), in the oligotrophic regions in winter time, and in the tropical regions during May to September. Prokaryotes show in general opposite annual cycles to these three PFTs and present more spatial complexity. The PFT anomaly of 2021 compared to the 20-year mean reveals mostly a slight decrease in diatoms and a prominent increase in haptophytes in most areas of the high latitudes, but no significant change for both in the mid to low latitudes, while prokaryotes show a clear decrease in the central tropical regions and increase in the western African coast (CNRY and GUIN) and southwest corner of NATR. Dinoflagellates, as a minor contributor to the total biomass, are relatively stable in the whole Atlantic region. This study illustrated the past and current PFT state in the Atlantic Ocean, and acted as the first step to promote long-term consistent PFT observations that enable time series analyses of PFT trends and inter-annual variability, to reveal potential climate induced changes in phytoplankton composition on multiple temporal and spatial scales.<\/jats:p>","DOI":"10.5194\/sp-2022-6","type":"posted-content","created":{"date-parts":[[2022,9,30]],"date-time":"2022-09-30T01:43:29Z","timestamp":1664502209000},"source":"Crossref","is-referenced-by-count":0,"title":["Two-decade satellite monitoring of surface phytoplankton functional types in the Atlantic Ocean"],"prefix":"10.5194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2827-0603","authenticated-orcid":false,"given":"Hongyan","family":"Xi","sequence":"first","affiliation":[]},{"given":"Marine","family":"Bretagnon","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2153-1954","authenticated-orcid":false,"given":"Svetlana N.","family":"Losa","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8612-4167","authenticated-orcid":false,"given":"Vanda","family":"Brotas","sequence":"additional","affiliation":[]},{"given":"Mara","family":"Gomes","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1531-1664","authenticated-orcid":false,"given":"Ilka","family":"Peeken","sequence":"additional","affiliation":[]},{"given":"Antoine","family":"Mangin","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3025-5517","authenticated-orcid":false,"given":"Astrid","family":"Bracher","sequence":"additional","affiliation":[]}],"member":"3145","container-title":[],"original-title":[],"deposited":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T16:57:34Z","timestamp":1737565054000},"score":1,"resource":{"primary":{"URL":"https:\/\/sp.copernicus.org\/articles\/1-osr7\/5\/2023\/sp-1-osr7-5-2023-discussion.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,9,30]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5194\/sp-2022-6","relation":{"has-comment":[{"id-type":"doi","id":"10.5194\/sp-2022-6-AC1","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/sp-2022-6-AC2","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/sp-2022-6-AC3","asserted-by":"subject"}],"has-review":[{"id-type":"doi","id":"10.5194\/sp-2022-6-RC1","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/sp-2022-6-RC2","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/sp-2022-6-RC3","asserted-by":"subject"}],"is-preprint-of":[{"id-type":"doi","id":"10.5194\/sp-1-osr7-5-2023","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/sp-1-osr7-5-2023","asserted-by":"object"}]},"subject":[],"published":{"date-parts":[[2022,9,30]]},"subtype":"preprint"}}
