Study of Belize Barrier Reef Shows Nitrogen Enrichment from Land-based Sources Doubled in Four Decades：What’s killing coral reefs in Florida is also killing them in Belize
coral reef nitrogen concentration algal blooms ecological system
2021/8/5
Only 17 percent of live coral cover remains on fore-reefs in Belize. A study finds new evidence that nitrogen enrichment from land-based sources like agriculture run-off and sewage, are significantly ...
Simultaneous measurement of the gross and net primary production of the benthic community and the net input of organic carbon delivered by currents to the coral reef flat of the north shore of Moorea,...
Multiple Sources and Forms of Nitrogen Sustain Year-Round Kelp Growth on the Inner Continental Shelf of the Santa Barbara Channel
Nitrogen Sustain Year-Round Kelp Growth Santa Barbara Channel
2015/7/16
Forests of the giant kelp Macrocystis pyrifera found on coastal rocky reefs lack the large reservoirs for nutrient storage found in many terrestrial environments. Supporting their high year-round grow...
Trace metal cycling in the deep water of the South China Sea: The composition, sources, and fluxes of sinking particles
Trace metal cycling in the deep water the South China Sea composition sources fluxes of sinking particles
2014/4/8
Moored sediment traps were deployed for 1 yr at depths of 120, 600, and 3500 m in the water column to investigate the trace metal (M) (Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) composition, sources, ...
Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...

2014/3/28
The total content of fat soluble vitamins and their percentages in the recommended daily intake for humans per 100 g portion, fatty acids composition, the atherogenic (IA) and thrombogenicity (IT) ind...
Characteristics and sources of chromophoric dissolved organic matter in lakes of the Yungui Plateau, China, differing in trophic state and altitude
Characteristics sources of chromophoric dissolved
2014/4/17
The high-mountain lakes on the Yungui Plateau in China are exposed to high-intensity ultraviolet radiation, and
contain low concentrations of chromophoric dissolved organic matter (CDOM). We determin...
Trace metal cycling in the surface water of the South China Sea: Vertical fluxes, composition, and sources
Trace metal cycling the surface water the South China Sea: Vertical fluxes composition sources
2014/4/16
We deployed floating traps in the surface waters of the South China Sea on four occasions at depths of 30 m,100 m, and 160 m from 2006 to 2007 to quantify vertical metal fluxes in the surface water an...
Isotope enrichment in mangrove forests separates microphytobenthos anddetritus as carbon sources for animals
Isotope enrichment mangrove ests separates microphy tobenthos anddetritus carbon sources animals
2014/4/16
Microphytobenthos (MPB) and mangrove detritus were labeled with a carbonisotope (13C) in separate experiments to quantify their contributions to the nutrition of major faunal components within a mangr...
