Project Overview

wetland nutrient transport south florida water management districtOfficials at the South Florida Water Management District oversee many stormwater treatment areas as part of their mission to manage and protect water resources in southern Florida. Those include many constructed wetlands, some with aquatic vegetation and some without.

Because the effects of aquatic vegetation on nutrient transport in wetlands are relatively unknown, scientists with the Management District set up monitoring equipment to learn more. Their investigation looks specifically at the role that wind plays in wetland nutrient transport, given the presence or absence of vegetation.

Their results may one day be useful for improving the management of SFWMD’s stormwater treatment areas, as well as reducing nutrient concentrations in the wetlands it oversees.

System Description

wetland nutrient transportResearchers elected to outfit two wetlands with solar-powered NexSens data loggers and Airmar 150WX Ultrasonic WeatherStation Instruments to find relationships between wind and nutrient movement. One wetland site has plenty of emergent aquatic vegetation, while the other is in an open-water area.

Each Airmar WeatherStation Instrument collects data on wind speed and direction, air temperature, barometric pressure, relative humidity and dew point. The information is recorded by the NexSens data loggers and later downloaded via direct connection by scientists with the District who view it via NexSens iChart software.

Though they are focusing on the effects of wind speed and direction on wetland nutrient transport, scientists with the District will chart the effects of each parameter. They expect wind will be strongly linked to nutrient transport, but that the presence of aquatic vegetation may help slow the movement down.

Equipment

NexSens iSIC Data Logger

Specifically designed for remote environmental monitoring applications, the iSIC data logger offers superior data acquisition performance in extreme conditions.


Airmar 150WX Ultrasonic WeatherStation Instrument

The Airmar 150WX is a compact weather station ideal for moving platforms. The sensor outputs apparent and true wind, barometric pressure, air temperature, GPS location, and more.
