Providing robust velocity measurements in a compact, easy-to-use package, the SonTek Argonaut-ADV is the ultimate instrument for shallow water flow monitoring. Ideal for low-flow applications in shallow streams, marshes, lakes, or water treatment facilities, the 3-axis (3D) Argonaut-ADV's advanced Doppler technology measures single-point velocity away from flow obstructions. All signal processing is done internally, allowing the Argonaut-ADV to be readily integrated with a wide range of additional sensors.

Innovative Study Quantifies Overland Flow in Mississippi Delta

Subsiding and choked off from the Mississippi River, southeastern Louisiana’s coastal marshlands have steadily sunk and become more saline.  According to U.S. Geological Survey (USGS) data, Louisiana is losing 24 square miles (62 square kilometers) of wetlands per year – wetlands that are nurseries of coastal fisheries and, as Hurricanes Katrina and Rita illustrated in 2004, can help absorb the brunt of storms blowing in from the Gulf of Mexico.  Recognizing the danger of continued wetland degradation and loss, state and federal officials are seeking ways to rebuild Louisiana’s threatened wetlands.
