Montserrat Pedrós-Alió, Carlos Symposium GLOBEC-IMBER España celebrado del 28-30 marzo de 2007 en Valencia.-- 1 page The metabolic diversity of bacterioplankton under the ice covered arctic shelf in Franklin Bay, Canadian Arctic, was studied using Biolog plates. Samples were taken weekly during the period December 2003-May 2004 at the surface, bottom and temperature inversion depths. Bacterioplankton in the Arctic used preferentially polymers and carbohydrates over carboxylic and amino acids. Surface chlorophyll a and bacterial concentration were low between December and March and started increasing in April, with the melting of the ice. Bacterial metabolic richness in spring, when chlorophyll a and bacterial concentrations were high, was markedly lower than in winter. Both at the temperature inversion depth and at the bottom samples chlorophyll a was lower than at the surface and bacterial metabolic richness did not show a clear difference between winter and spring. At both layers, a period of high metabolic richness was found during February and March that may correspond to sedimentation or resuspension events of organic matter. The results show that, despite the oligotrophic conditions in winter, metabolic richness of surface bacterioplankton was higher than in spring, suggesting that bacteria might use preformed organic matter under the sea ice coverage. Metabolic diversity of bacterioplankton in the Arctic will be compared with that found in other oceans Peer reviewed 2020-02-13T13:19:16Z 2020-02-13T13:19:16Z 2007-03 comunicación de congreso http://purl.org/coar/resource_type/c_5794 Symposium GLOBEC-IMBER España : Libro de resúmenes: 16 (2007) http://hdl.handle.net/10261/200579 en Sí none
