Many coastal states throughout the USA have observed negative effects in marine and
estuarine environments caused by cyanotoxins produced in inland waterbodies that were …

Globally, precipitation is expected to increase along with the rise of temperatures due to
climate change, increasing the likelihood of freshwater intrusion into coastal ecosystems. In …

Large freshwater pulses to coastal ecosystems change local hydrologic regimes and alter
biogeochemical processes. The Mississippi Bight coastal ecosystem, located in the northern …

Recent studies have shown that Lake Pontchartrain Estuary in Louisiana experiences

Diffusive flux of bioavailable soluble reactive phosphorus (SRP) across the sediment–water
interface is one mechanism by which sediments can be a source of phosphorus to the water …

Phosphorus (P) is an important macronutrient that can limit primary productivity in coastal
marine ecosystems. This study provides a quantitative determination of abundance and …

Abstract Nitrate (NO 3−) and ammonium (NH 4+) are reactive nitrogen (N r) forms that can
exacerbate eutrophication in coastal regions. NO 3− can be lost to the atmosphere as N 2 …

Oyster reefs provide essential ecosystem services but are severely degraded worldwide.
Extreme flooding events, which can be intensified by water management decisions, reduce …
