An empirical model of the phytoplankton chlorophyll : carbon ratio‐the conversion factor between productivity and growth rate
TL;DR: An empirical model that describes the ratio of phytoplankton chlorophyll a to carbon, Chl : C, as a function of temperature, daily irradiance, and nutrient-limited growth rate gives rise to interactive light-nutrient effects in which growth efficiency increases with nutrient availability under low-light conditions.
Journal ArticleDOI
Eutrophication and some European waters of restricted exchange
Paul Tett,Linda Gilpin,Harald Svendsen,Carina P. Erlandsson,Ulf Larsson,Susanne Kratzer,Eric Fouilland,Carol Janzen,Jae-Young Lee,Christian Grenz,Alice Newton,João G. Ferreira,Teresa F. Fernandes,Serge Scory +13 more
TL;DR: The OAERRE project (EVK3-CT1999-0002) concerns Oceanographic Applications to Eutrophication in Regions of Restricted Exchange (RREs).
Journal ArticleDOI
Trawling-induced resuspension and dispersal of muddy sediments and dissolved elements in the Gulf of Lion (NW Mediterranean)
X. Durrieu de Madron,Bénédicte Ferré,G. Le Corre,Christian Grenz,Pascal Conan,Mireille Pujo-Pay,Rosalyne Buscail,O. Bodiot +7 more
TL;DR: A dedicated trawling experiment was performed at three sites on the Gulf of Lion continental shelf, with the aim of assessing the resuspension of particulate and dissolved matter triggered by different types of trawls on muddy sediments as discussed by the authors.
Journal ArticleDOI
Benthic biogeochemistry: state of the art technologies and guidelines for the future of in situ survey
Eric Viollier,Christophe Rabouille,Se Apitz,E. Breuer,Gwénaëlle Chaillou,Karine Dedieu,Yoko Furukawa,Christian Grenz,Per O. J. Hall,Felix Janssen,Jl Morford,Jean-Christophe Poggiale,Steve G. Roberts,T Shimmield,Martial Taillefert,Anders Tengberg,Frank Wenzhöfer,Ursula Witte +17 more
TL;DR: A review of existing in situ technologies for the study of benthic biogeochemistry dynamics and related scientific applications is presented.
Journal ArticleDOI
Dynamics of nutrient cycling and related benthic nutrient and oxygen fluxes during a spring phytoplankton bloom in South San Francisco Bay (USA)
TL;DR: These models show that algal blooms influence benthic-pelagic nutrient exchange through 2 processes: depletion of nutrients from the water column (which enhances gradient-driven transports across the sediment-water interface) and sedimentation of labile phytodetritus (which promotes remineralization in or on the surficial sediments).
