Climate change and marine plankton.
The interactions between climate change and plankton communities are reviewed, focusing on systematic changes in plankton community structure, abundance, distribution and phenology over recent decades, to consider the potential socioeconomic impacts.
A biogeochemical study of the coccolithophore, Emiliania huxleyi, in the North Atlantic
The biogeochemical properties of an extensive bloom (∼250,000 km2) of the coccolithophore, Emiliania huxleyi, in the north east Atlantic Ocean were investigated in June 1991. Satellite (NOAA-AVHRR)…
Heterotrophic Bacterial Respiration
Marine heterotrophic bacteria are ubiquitous and abundant, occurring from the sea surface microlayer to the deepest ocean depths, at densities measured in millions of cells per milliliter of…
Elevated consumption of carbon relative to nitrogen in the surface ocean
UPTAKE of atmospheric CO2 by the ocean's 'biological pump' is driven by export of carbon from the euphotic zone to deeper waters1,2. As nitrate is a limiting nutrient in large regions of the ocean,…
A communal catalogue reveals Earth’s multiscale microbial diversity
A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project is presented, creating both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity.
Respiration and its measurement in surface marine waters
Outline This chapter reviews the current state of knowledge of the process and measurement of microplankton respiration in marine surface waters. The principal approaches are outlined and their…
Review of gross community production, primary production, net community production and dark community respiration in the Gulf of Lions
Abstract Thirty years of data were used to examine the influence of the Rhoˆne River discharge on the spatio-temporal distribution of primary production in the Gulf of Lions. These patterns are…
Plankton respiration in the Eastern Atlantic Ocean
At the time of the study, plankton community respiration exceeded GP in the picoautotroph dominated oligotrophic regions (Eastern Tropical Atlantic and North Atlantic Subtropical Gyre), which exhibited high heterotrophic: autotrophic biomass ratios, higher turnover rates of phytoplankton than of bacteria and low f ratios.
Net accumulation and flux of dissolved organic carbon and dissolved organic nitrogen in marine plankton communities
Marine mesocosms were manipulated with inorganic nutrients over a period of 22 d to investigate organic carbon partitioning under a variety of nutrient regimes. The chemical analyses and biotic…
Mesopelagic zone ecology and biogeochemistry - a synthesis
G gaps in knowledge are identified and suggestions made for priority research programmes that will improve the ability to predict the effects of climate change on carbon sequestration.
