Última Response of benthic organisms to seasonal change of organic matter deposition in the bathyal Sagami Bay, central Japan ArchiMer Shimanaga, M; Shirayama, Y. An interdisciplinary research project was carried out to understand seasonal carbon cycling in a deep-sea ecosystem in Sagami Bay, central Japan. Temporal-changes in the chloroplastic pigment (CPE) concentration in the sediment, as well as the abundance, the biomass and the metabolic activity of benthic organisms were studied. CPE was detectable throughout the year, and its amount increased in the spring when a fluffy layer was observed on the surface of the sediment. Significant seasonal fluctuation of bacterial abundance was found, but the range was small, the maximal value being only 1.6 times larger than the minimal one. Metabolic activity did not show significant temporal difference. The abundance and biomass of metazoan meiofauna seemed to fluctuate...

A study was conducted to assess the annual variability in planktonic metabolism and dissolved organic carbon (DOC) utilization in an oligotrophic Mediterranean Bay (Bay of Palma, Spain) and to test the role of elevated DOC concentrations in driving planktonic metabolism off balance. We examined, at monthly intervals over 17 mo, gross primary production (GPP), community respiration (R), net community production (NCP), DOC concentration, total chlorophyll a (chl a) concentration, and, for a smaller subset of 11 to 14 mo, net DOC fluxes, bacterial abundance (BA) and bacterial respiration (BR). The community was net heterotrophic in autumn, winter and the first summer studied, and shifted to net autotrophic towards the end of the study period. This period of...

Ano: 2004 URL: https://archimer.ifremer.fr/doc/00247/35854/34373.pdf Distribution of HNA and LNA bacterial groups in the Southwest Atlantic Ocean BJM Andrade,Luciana; Gonzalez,Alessandra M.; Rezende,Carlos Eduardo; Suzuki,Marina; Valentin,Jean Louis; Paranhos,Rodolfo. Bacterioplankton was studied in a large area of Southwest Atlantic Ocean between 13 and 25ºS and 28 and 42ºW. Samples were collected in 108 stations at 20 m depth. Bacteria were enumerated by flow cytometry after nucleic acid staining with syto13 and two subgroups were differentiated: low nucleic acid content (LNA) and high nucleic acid content (HNA) bacteria. Total bacterial numbers varied from 0.37 to 5.53 10(5) cells mL-1. HNA cells represented 15 to 70% of the total number while LNA cells represented 30 to 85%. Heterotrophic bacterial production was determined by incorporation of tritiated leucine and ranged from 2.7 to 171.07 ng C L-1 h-1. No significant correlation was found between abundance and production. Nevertheless with support of multivariate...
