estuarine circulation

[′es·chə·wə‚rēn ‚sər·kyə¦lā·shən]
(oceanography)
In an estuary, the outflow (seaward) of low-salinity surface water over a deeper inflowing layer of dense, high-salinity water.

This freshwater influx then forces estuarine circulation in the southern strait, which is characterized by a net outflow of low salinity water toward Juan de Fuca Strait in the upper layer (<50 m depth), and a net northward inflow of high salinity water in the lower part of the water column that reaches the Strait of Georgia in late summer (Mosher and Thomson, 2002).
It is likely that deep flood tides and estuarine circulation during summer construct the dunes.
A 20-minute mini-lecture was presented to the students to introduce three major concepts: (1) the characteristics of estuaries, (2) variations in estuarine circulation patterns, and (3) the nature of plankton.
ABSTRACT Planktonic larvae of resident, oyster reef-associated decapods and fishes are subject to variable transport and retention whenever estuarine circulation is altered by freshwater inflow.
Tidal currents, which act independently of estuarine circulation, also add to the turbulence, mixing the salt and flesh waters to produce brackish water in the estuary.
Data collected at the monitoring sites are also useful for investigating problems related to estuarine circulation.
Subsequently, estuarine circulation is important in determining sediment transport and distribution (Dyer 1979).
In coastal lagoons of arid regions with permanent connection to the sea and negative estuarine circulation, penaeid shrimp develop a particular life cycle that differs from that accepted for the general shrimp ecology.
The rivers that drive Long Island Sound's estuarine circulation discharge along its broad northern flank.
This contribution focuses on the importance of site selection in this effort, paying particular attention to the roles of (1) demographics and disease status on fecundity of brood stock, (2) larval feeding and growth rate in high-turbidity conditions typical of low-salinity sanctuaries from disease, (3) ontogenetic changes in larval behavior in such conditions, and (4) the role of estuarine circulation in retaining larvae in regions suitable for subsequent recruitment.
