The 'phytoplankton factory' -- from nutrients to algae growth
phytoplankton ocean ecosystems climate change
2021/8/9
Phytoplankton are the foundation of ocean ecosystems: like rainforests, they consume carbon from the atmosphere, form the basis of the marine food web and have a decisive influence on fish abundance a...
Freshwater runoff from rivers brings more carbon, nutrients to Arctic Ocean（图）
Freshwater runoff rivers carbon nutrients Arctic Ocean
2020/4/17
A new study by National Science Foundation-funded researchers at the Woods Hole Oceanographic Institution and their colleagues found that freshwater runoff from rivers and continental s...
Coexisting in a Sea of Competition Similar Diatom Species Seek Out Nutrients in Different Ways
Diatom Species Seek Out Nutrients Different Ways
2015/4/29
Diversity of life abounds on Earth, and there's no need to look any farther than the ocean's surface for proof. There are over 200,000 species of phytoplankton alone, and all of those species of micro...
Phytoplankton communities and care interactively affected by light, nutrients, and fish
Phytoplankton communities interactively
2014/4/4
We examined the separate and interactive effects of light, nutrients, and zooplanktivorous fish on
phytoplankton nutrient stoichiometry, taxonomic richness, community composition, and the association...
Shifts in limiting nutrients in an estuary caused by mixing and biological activity
limiting nutrients mixing biological activity
2014/4/8
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a
nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...

Interactions between limiting nutrients: Consequences for somatic and population growth of Daphnia magna
Interactions between limiting nutrients population growth of Daphnia magna
2014/4/17
To assess the significance of nutrient interactions on animal performance, life-history experiments were
conducted with the freshwater herbivore Daphnia magna in a system with two limiting nutrients ...
Relationships between phytoplankton growth and cell size in surface oceans: Interactive effects of temperature, nutrients, and grazing
phytoplankton growth cell size in surface oceans Interactive effects temperature nutrients grazing
2014/4/17
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
Influence of water-column depth and mixing on phytoplankton biomass, community composition, and nutrients
Influence of water-column depth mixing on phytoplankton biomass community composition nutrients
2014/4/21
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...
Large, non-Redfieldian drawdown of nutrients and carbon in the extratropical North Atlantic Ocean (46uN): Evidence for dinitrogen fixation?
non-Redfieldian drawdown of nutrients carbon
2014/4/21
Considerable drawdown of total dissolved inorganic carbon (CT) and oversaturation of oxygen (O2
) within a
cold (,15uC) oligotrophic eddy in the extratropical North Atlantic Ocean (46uN, 20.5uW) ind...

2014/4/18
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separateand combined effec...
Variable effects of marine-derived nutrients on algal production in salmon nursery lakes of Alaska during the past 300 years
marine-derived nutrients algal production salmon nursery lakes Alaska during the past 300 years
2014/4/22
We measured historical changes in sedimentary δ15N and fossil pigments in four lakes with anadromous semelparous salmon and two reference lakes to quantify the degree to which the flux of marine-deriv...
Long-term trends in eutrophication and nutrients in the coastal zone
eutrophication nutrients coastal zone
2014/4/30
We used high-resolution paleoecological records of environmental change to study the rate and magnitude of
eutrophication over the last century in two contrasting coastal ecosystems. A multiproxy app...
Comprehensive trend analysis of nutrients and related variables in a large eutrophic estuary: A decadal study of anthropogenic and climatic influences
Comprehensive trend analysis related variables
2014/4/30
We used a decadal data set, with weekly to biweekly sampling in April–October and monthly sampling in November–
March, to characterize climatic (hurricane-level storms, a sustained 3-yr drought) and ...

2014/4/30
We investigated long-term trends (1965–2002) in dissolved inorganic nutrients in the tidal part of the Scheldt
estuary (Belgium, The Netherlands). Annually averaged concentrations of dissolved silica...
