Synthesis in estuarine and coastal ecological research: What is it, why is it important and how do we teach it?

During the last two decades, there has been growing interest in the integration of existing ideas and data to produce new synthetic models and hypotheses leading to discovery and advancement in estuarine and coastal science. This essay offers an integrated ...

Temporal responses of coastal hypoxia to nutrient loading and physical controls

The incidence and intensity of hypoxic waters in coastal aquatic ecosystems has been expanding in recent decades coincident with eutrophication of the coastal zone. Worldwide, there is strong interest in reducing the size and duration of hypoxia in coastal waters, ...

The metabolism of aquatic ecosystems: History, applications, and future challenges

Measurements of the production and consumption of organic material have been a focus of aquatic science for more than 80 years. Over the last century, a variety of approaches have been developed and employed for measuring rates of gross primary ...

The role of winter-spring wind and other factors controlling summer hypoxia in Chesapeake Bay

We examined the processes influencing summer hypoxia in the mainstem portion of Chesapeake Bay. The analysis was based on the Chesapeake Bay Monitoring Program data collected between 1985 and 2007. Self-organizing map (SOM) analysis indicates that bottom water dissolved oxygen ...

Variability of biogeochemical processes and physical transport in a partially stratified estuary: a box-modeling analysis

Regional, seasonal, and interannual variations of freshwater inputs, biogeochemical transformations, and pelagic-benthic interactions were examined in the Patuxent River estuary. Monthly rates of net biogeochemical production (or consumption) and physical transport of carbon, oxygen, and nutrients were calculated for 6 ...

Wind-driven lateral circulation in a stratified estuary and its effects on the along-channel flow

In the stratified rotating estuary of Chesapeake Bay, the Ekman transport drives a counterclockwise lateral circulation under down?estuary winds and a clockwise lateral circulation under up?estuary winds (looking into estuary). The clockwise circulation is about twice as strong as the ...
