Salt marsh resilience compromised by crabs along tidal creek edges
coastal marshes ecosystem crab
2021/8/10
Coastal marshes are vulnerable to erosion caused by rising seas, pounding waves, and tidal flows. In California's Elkhorn Slough, these vulnerabilities are made worse by superabundant crabs found at t...
Salt marshes' capacity to store carbon may be threatened by nitrogen pollution（图）
Salt marshes capacity carbon nitrogen pollution
2019/10/18
Deep in the waterlogged peat of salt marshes, carbon is stored at much greater rates than in land ecosystems, serving as an offset to climate change caused by carbon dioxide (CO2) build-up in the atmo...
There is probably nothing more foundational to understanding the ocean than the study of salinity. New discoveries regarding its magnitude and variability continue to feed our knowledge of the nature ...
The following is part sixteen in a series on the National Science Foundation's Long-Term Ecological Research (LTER) Network. Visit parts one, two, three, four, five, six, seven, eight, nine, ten, elev...
Salt marsh tidal exchange increases residence time of silica in estuaries
Salt marsh tidal exchange increases residence time of silica in estuaries

We present flux measurements of dissolved silicon (DSi), biogenic Si (BSi), and dissolved inorganic nitrogen (DIN) and phosphorus (DIP) on a temperate salt marsh in Narragansett Bay, Rhode Island, ove...
Nitrogen enrichment increases net silica accumulation in a temperate salt marsh
Nitrogen enrichment increases net silica accumulation a temperate salt marsh

Two New England salt marshes exposed to different N availability were assessed seasonally for 1 yr, creating the first complete salt marsh Si budgets. Triplicate seasonal measurements were collected f...
The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
2014/4/4
Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...
Hypoxic events stimulate nitrogen recycling in a shallow salt-wedge estuary: The Yarra River estuary, Australia
Hypoxic events stimulate nitrogen recycling shallow salt-wedge estuary The Yarra River estuary Australia
2014/4/4
The Yarra River estuary is a salt-wedge estuary prone to periods of stratification-induced anoxia and hypoxia (O2 < 100 μmol L−1) during low-flow events. Nitrate reduction pathways were examined...

We describe the circulation of Tailings Lake, located 220 km north of Yellowknife, Northwest Territories,Canada. From Jul 2004 to Sep 2007, temperature and conductivity profiles were collected togethe...
The effect of increased nitrate loading on nitrate reduction via denitrification and DNRA in salt marsh sediments

2014/4/16
The effects of increased nitrogen loading on denitrification and dissimilatory nitrate reduction to ammonium
(DNRA) in marsh sediments were studied in permanently submerged subtidal creek sediments a...
Increased supply of ambient nitrogen has minimal effect on salt marsh bacterial production
Increased supply of ambient nitrogen salt marsh

We examined the role of chronic low-level nutrient enrichment on the productivity of heterotrophic marsh
bacteria via a marsh fertilization experiment in which we mimicked the conditions of widesprea...
Salt marshes and eutrophication: An unsustainable outcome
An unsustainable outcome Salt marshes
2014/4/17
Most plant production by emergent coastal marshes occurs belowground. This belowground production adds
to the accumulation of organic matter sustaining salt marshes as sea level rises, thus preventin...
Salt Fingers Observed in the Mediterranean Outflow Region (34°N, 11°W) Using a Towed Sensor
Mediterranean Outflow Region Towed Sensor Salt Fingers
2009/3/7
A towed microstructure instrument has been used to measure small-scale conductivity fluctuations in a quasi-horizontal plane, as well as local vertical gradients of temperature and conductivity. This ...
