Despite the high abundance of Archaea in global ocean, their metabolism and biogeochemical roles remain largely unresolved. We investigated population dynamics metabolic activity Thaumarchaeota polar environments, where these microorganisms are particularly abundant exhibit seasonal growth. were more deep Arctic Antarctic waters grew throughout winter at surface deeper halocline waters. However, situ single-cell measurements revealed a low this group uptake both leucine bicarbonate (<5%...
Abstract The role of the ocean as a sink for CO 2 is partially dependent on downward transport phytoplankton cells packaged within fast-sinking particles. However, whether such mechanisms deliver fresh organic carbon down to deep bathypelagic sea and this mechanism prevalent across requires confirmation. Here we report ubiquitous presence healthy photosynthetic cells, dominated by diatoms, 4,000 m in dark ocean. Decay experiments with surface suggested that large proportion (18%) observed,...
Primary production by marine phytoplankton is one of the largest fluxes carbon on our planet. In past few decades, considerable progress has been made in estimating global primary at high spatial and temporal scales combining situ measurements with remote-sensing observations biomass. One major challenges this approach lies assignment appropriate model parameters that define photosynthetic response to light field. present study, a database photosynthesis versus irradiance (P-I) 20-year...
A well-developed deep chlorophyll maximum (DCM) is a prominent feature of the Northwestern Mediterranean during large part year.Data from 7 oceanographic surveys carried out across Catalano-Balearic Sea, between 1982 and 1987, have been used to analyze shortterm (within cruises) seasonal+interannual (between variation several parameters (such as surface DCM concentration, integrated chlorophyll, DCM, nitracline nitrite depths).S~gnificant positlve correlations (p < 0.01) were found depths...
Viral activity exerts a particularly important role in the dark ocean across global tropical and subtropical oceans.
Abstract Global patterns of planktonic diversity are mainly determined by the dispersal propagules with ocean currents. However, role that abundance and body size play in determining spatial remains unclear. Here we analyse community structure - β-diversity for several nektonic organisms from prokaryotes to small mesopelagic fishes collected during Malaspina 2010 Expedition. was compared surface transit times derived a global circulation model, revealing significant negative relationship is...
Climate warming affects the development and distribution of sea ice, but at present evidence polar ecosystem feedbacks on climate through changes in atmosphere is sparse. By means synergistic atmospheric oceanic measurements Southern Ocean near Antarctica, we that microbiota ice ice-influenced ocean are a previously unknown significant source organic nitrogen, including low molecular weight alkyl-amines. Given keystone role nitrogen compounds aerosol formation, growth neutralization, our...
We examine the large-scale distribution patterns of nano- and microphytoplankton collected from 145 oceanic stations, at 3 m depth, 20% light level depth subsurface chlorophyll maximum, during Malaspina-2010 Expedition (December 2010-July 2011), which covered 15 biogeographical provinces across Atlantic, Indian Pacific oceans, between 35°N 40°S. In general, water column was stratified, surface layers were nutrient-poor microplankton (hereafter phytoplankton, for simplicity, although it...
Abstract. Marine diazotrophs convert dinitrogen (N2) gas into bioavailable nitrogen (N), supporting life in the global ocean. In 2012, first version of oceanic diazotroph database (version 1) was published. Here, we present an updated 2), significantly increasing number situ diazotrophic measurements from 13 565 to 55 286. Data points for N2 fixation rates, cell abundance, and nifH gene copy abundance have increased by 184 %, 86 809 respectively. Version 2 includes two new data sheets...
Abstract. Coccolithophores are calcifying marine phytoplankton of the class Prymnesiophyceae. They considered to play an import role in global carbon cycle through production and export organic calcite. We have compiled observations coccolithophore abundance from several existing databases as well individual contributions published unpublished datasets. make conservative estimates biomass using standardised conversion methods provide uncertainty associated with these values. The...
We carried out monthly photosynthesis-irradiance (P-E) experiments with the 14C-method for 12 years (2003–2014) to determine photosynthetic parameters and primary production of surface phytoplankton in Blanes Bay Microbial Observatory, a coastal sampling station NW Mediterranean Sea. Our goal was obtain seasonal trends establish basis detecting future changes this oligotrophic area. The maximal rate PBmax ranged 30-fold (0.5-15 mg C Chl a–1 h–1), averaged 3.7 h–1 (±0.25 SE) highest August...
The oligotrophic subtropical gyres are the largest biome on Earth, where picoplankton constitute dominant autotrophs. trend for autotrophic to increase with sea temperature has led predictions that picophytoplankton abundance will warming. Here we conducted a global survey in open subtropical-tropical ocean resolve functional relationships between and oceanic properties (water temperature, chlorophyll concentration, nutrient concentrations, underwater visible ultraviolet B radiation). We...
Deep ocean microbial communities rely on the organic carbon produced in sunlit ocean, yet it remains unknown whether surface processes determine assembly and function of bathypelagic prokaryotes to a larger extent than deep-sea physicochemical conditions. Here, we explored variations phytoplankton assemblages across Atlantic, Pacific Indian stations can explain structural changes (ca. 4,000 m) free-living particle-attached prokaryotic (characterized through 16S rRNA gene sequencing), as well...
Sea spray aerosol (SSA) formation plays a major role in the climate system. The Antarctic Peninsula (AP) is affected by greatest warming occurring Southern Ocean; changes cryospheric and biological processes are being observed. Whilst there some evidence that organic material produced ice algae and/or phytoplankton high Arctic contributes to SSA, less known about (sympagic) regions. To gain insight into influence of biology biogeochemistry on atmospheric aerosol, we report simultaneous...
