These are anomalous coccospheres bearing coccoliths of two or more coccolithophore species. Unlike combination coccospheres, these are almost certainly the products of post mortem processes. Possible mechanisms of formation are discussed, and comparative examples of unambiguous agglutination by tintinnids and foraminifera, and in pellets, are illustrated. The need for caution in interpreting putative combination coccospheres is highli ghted.","PeriodicalId":186533,"journal":{"name":"Journal of Nannoplankton Research","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116880261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"Impact of a Coccolithus braarudii bloom on the carbonate system of Portuguese coastal waters.","authors":"A. P. Oliveira","doi":"10.58998/jnr2051","DOIUrl":"https://doi.org/10.58998/jnr2051","url":null,"abstract":"In the adjacent Tagus and Sado coastal waters (off SW Portugal), a phytoplankton bloom dominated by diatoms (up to 1000 cells ml -1 ) was observed, in spring 2002, under upwelling conditions. Overlapping with the phytoplankton bloom, but spatially differentiated from the diatoms and other phytoplankton groups, a pronounced development of the coccolithophore Coccolithus braarudii (up to 60 cells ml-1) occurred, associated with a thermal- ly stratified water-mass localised in the Tagus Bay. Some cells of the C. braarudii hyalinus-phase were also observed. A production of about five tons of calcite was calculated for the upper 30m of the water-column, based on the integration over depth of a total of 6.7g CaCO 3 m-2, covering 0.7km2 of the Tagus Bay. An average CaCO 3 pre- cipitation rate of 11.2mmol CaCO3 m-2 d-1 was estimated, resulting in the release of 7.4mmol CO2 m-2 d-1 during the C. braarudii bloom. These results indicate that the studied coastal system contributed an additional source of CO2 to the water, and eventually to the atmosphere.","PeriodicalId":186533,"journal":{"name":"Journal of Nannoplankton Research","volume":"9 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129866728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
