Researchers track nutrient transport in the Gulf of Mexico（图）
nutrient transport Gulf Mexico
2020/9/18
The Gulf of Mexico receives considerable levels of nutrients from the rivers that empty into it, especially the Mississippi River, causing the Gulf's northern waters to become overly enriched and more...
Reducing nutrient pollution helps corals resist bleaching（图）
Reducing nutrient pollution corals resist bleaching
2020/3/6
Reducing nutrient pollution can help prevent coral reefs from bleaching during moderate heatwaves, according to a National Science Foundation-funded study by researchers at UC Santa Barbara....
The nutrient phosphate may be less abundant in the global ocean than previously thought, according to a new paper in Science Advances. The researchers compiled data collected using sensitive technique...
Algae-killing viruses spur nutrient recycling in oceans（图）
Algae-killing viruses nutrient recycling oceans
2019/10/23
Scientists have confirmed that viruses can kill marine algae called diatoms, but diatom die-offs near the ocean surface may provide nutrients and organic matter for recycling by other algae.Diatoms ar...
Interannual and Subdecadal Variability in the Nutrient Geochemistry of the Cariaco Basin
Interannual and Subdecadal Variability Nutrient Geochemistry Cariaco Basin
2015/7/17
The CARIACO Ocean Time Series program has made monthly measurements of oxygen, nutrients, and carbon system parameters (∑CO2, alkalinity, pH) in the Cariaco Basin since 1996. At the same time, sedimen...
Patterns and Controls of Nutrient Concentrations in a Southeastern United States Tidal Creek
Nutrient Concentrations Southeastern United States
2015/7/16
Terrestrial inputs largely govern nutrient delivery to the coastal ocean, and subsequent processes transform these nutrients in the land-ocean transition zone. Here, we describe spatial and temporal p...
Homeostasis and nutrient limitation of benthic autotrophs in natural chemostats
natural chemostats benthic autotrophs
2014/11/28
To explore how gradients in nutrient availability influence the stoichiometry of freshwater autotrophs, we
sampled algal and submerged vascular plant tissues, as well as water for C : N : P ratios in...
Nutrient availability affects the response of juvenile corals and the endosymbionts to ocean acidification
ocean acidification Juvenile coral
2014/10/16
The interactive effects of nutrient availability and ocean acidification on coral calcification were investigated
using post-settlement juvenile corals of Acropora digitifera cultured in nutrient-suf...
Like weeds of the sea, 'brown tide' algae exploit nutrient-rich coastlines（图）
brown tide sea nutrient-rich coastlines
2014/9/12
The sea-grass beds of Long Island’s Great South Bay once teemed with shellfish. Clams, scallops and oysters filtered nutrients from the water and flushed money through the local economy. But three dec...
Episodic vertical nutrient fluxes and nearshore phytoplankton blooms in Southern California
Episodic vertical nutrient fluxes nearshore phytoplankton blooms Southern California
2014/4/2
Three distinct phytoplankton blooms lasting 4–9 d were observed in approximately 15-m water depth near Huntington Beach, California, between June and October of 2006. Each bloom was preceded by a vert...
Trait-based models of nutrient uptake in microbes extend the MichaelisMenten framework
Trait-based models nutrient uptake microbes extend MichaelisMenten framework
2014/4/2
In microbial competition theory, the Michaelis-Menten (MM) half-saturation coefficient is often considered to be a trait of an organism defining competitive strength in a trade-off conflict with maxim...
Nutrient loading and meteorological conditions explain interannual variability of hypoxia in Chesapeake Bay
Nutrient loading meteorological conditions Chesapeake Bay
2014/4/2
We use geostatistical universal kriging and conditional realizations to provide the first quantitative estimates,
with robust estimates of uncertainties, of the seasonal and interannual variability i...
Mats of the nonnative macroalga, Gracilaria vermiculophylla, alter net denitrification rates and nutrient fluxes on intertidal mudflats
nonnative macroalga Gracilaria vermiculophylla
2014/4/2
We hypothesized that mats of a nonnative macroalga, Gracilaria vermiculophylla, which is often found
incorporated several centimeters into intertidal mudflat sediments, would increase net denitrifica...
Light and nutrient control of photosynthesis in natural phytoplankton populations from the Chukchi and Beaufort seas, Arctic Ocean
Light nutrient control of photosynthesis
2014/4/2
During the 2010–2011 ‘Impacts of Climate Change on the EcoSystems and Chemistry of the Arctic Pacific
Environment’ project, we measured photosynthetic parameters in natural Arctic phytoplankton assem...
Response of phytoplankton in an alpine lake to inputs of dissolved organic matter through nutrient enrichment and trophic forcing
Response of phytoplankton trophic forcing
2014/4/2
Inputs of terrestrially derived dissolved organic matter (DOM) are increasing in alpine lakes due to multiple
drivers such as climate change, tree line advancement, and insect epidemics. A 21 d micro...
