Diversity and productivity of photosynthetic picoeukaryotes in biogeochemically distinct regions of the South East Pacific Ocean
Picophytoplankton, including photosynthetic picoeukaryotes (PPE) and unicellular cyanobacteria, are important contributors to plankton biomass and primary productivity. In this study, phytoplankton composition and rates of carbon fixation were examined across a large trophic gradient in the South East Pacific Ocean (SEP) using a suite of approaches: photosynthetic pigments, rates of C-primary p...
متن کاملCalcite production by Coccolithophores in the South East Pacific Ocean: from desert to jungle
BIOSOPE cruise achieved an oceanographic transect from the Marquise Islands to the Peru-Chili upwelling (PCU) via the centre of the South Pacific Gyre (SPG). Water samples from 6 depths in the euphotic zone were collected at 20 stations. The concentrations of suspended calcite particles, coccolithophores cells and detached coccoliths 5 were estimated together with size and weight using an autom...
متن کاملPrasinoderma singularis sp. nov. (Prasinophyceae, Chlorophyta), a solitary coccoid Prasinophyte from the South-East Pacific Ocean.
During the BIOSOPE cruise in the South-East Pacific Ocean in 2004, several unidentified strains of prasinophytes were isolated into culture. Of these, nine strains composed a group for which the partial 18S rRNA gene sequence was related to Prasinoderma coloniale. The ultrastructure, morphology, division process, pigment composition, genome size and molecular genetic phylogeny of these nine str...
متن کاملOrganochlorine contaminants in albatross from the South Pacific Ocean
1. Albatross eggs and embryos were collected in field seasons from 1996 to 1998 by Department of Conservation field staff. Species collected were the Northern Royal albatross (Diomedea sanfordi), Northern Buller's mollymawk (Thalassarche (platei) (nova sp.)) and Chatham Islands mollymawk (Thalassarche eremita). 2. Tissues were submitted to ESR for chemical analysis. Chemicals of particular inte...
متن کاملBiological N2O Fixation in the Eastern South Pacific Ocean and Marine Cyanobacterial Cultures
Despite the importance of nitrous oxide (N2O) in the global radiative balance and atmospheric ozone chemistry, its sources and sinks within the Earth's system are still poorly understood. In the ocean, N2O is produced by microbiological processes such as nitrification and partial denitrification, which account for about a third of global emissions. Conversely, complete denitrification (the diss...
