The CB-40 Data Buoy offers a compact and affordable platform for deploying water quality sondes and other instruments that integrate power and data logging. The lightweight platform can be deployed from small boats, large vessels or even helicopters, making it the ideal choice for applications where water needs to be monitored at a moment’s notice. The buoy can also be used as an underwater float and instrument housing for subsurface deployments.
The buoy is constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin and stainless steel frame. An optional 1-3 NM solar marine light mounts over the topside access hole, and three eyenuts offer a convenient lifting point. The CB-40 supports a 1, 2, or 3-point mooring via bottom bow shackle and three eyenuts. Optional accessories include chain, shackles and anchors for buoy mooring.
The CB-40 Data Buoy weighs 38 lbs. with no payload and approximately 45 lbs. with integrated solar marine light and water quality sonde. The 4" stainless steel instrument pipe securely houses the instrument and includes slotted holes for water flow. Compatible instruments include YSI 6-Series & EXO sondes, Hydrolab Series 5 & HL sondes, Eureka Manta sondes, and In-Situ Aqua TROLL instruments.
- Hull Dimensions: 14" (35.56cm) outside diameter; 20" (50.80cm) tall
- Instrument Pipe Dimensions: 3.87" (9.83cm) inside diameter; 48" (121.92cm) tall
- Weight: 38 lbs. (no payload); 45 lbs. (with sonde & solar marine light)
- Buoyancy: 40 lbs.
- Hull Material: Cross-linked polyethylene foam with polyurea coating & stainless steel deck
- Hardware Material: 304 stainless steel
- Mooring Attachments: 1, 2, or 3 point
The instrument deployed in the buoy can have internal logging (i.e. multi-parameter sonde) although there is no data logger option for this model. The CB-50 and larger buoy platforms support NexSens X2 data loggers.
No, the CB-50 and larger buoy platforms can accommodate this feature.
Any submersible instrument with internal power & data logging that fits within a 4” diameter x 48” long pipe could be deployed from this platform.
There are no waterproof housing compartments on this platform. The CB-150 and larger buoy platforms can accommodate sensitive electronics inside the data well.
The CB-40 can be deployed subsurface with an anchor heavier than the net buoyancy of the deployed equipment. This is useful when monitoring at a fixed distance from the bottom of the water body.

Snowmelt, Stormwater and Contamination in Saskatoon
In Saskatoon, Saskatchewan, pollution and runoff from storms and snowmelt are getting the close look they deserve, and there’s much more to examine. Weather, from heavy spring storms to long months of snow and freezing temperatures, makes the polluting potential of runoff and snowmelt greater than and different from warmer climate cities, said Garry Codling in an email. In Saskatoon, potentially harmful elements in runoff can exceed the guidelines for runoff set by the Canadian government.

Appalachian streams show long, slow recovery from mining’s lingering effects
Appalachia may be as closely associated with mining as it is to anything else. That close relationship will leave its mark on the area’s streams long after the last mine closes. A nine-year study recently published in Science of the Total Environment shows that long after mining activity stops and the land is left to heal, streams and stream life are slow to recover. “We could be really fine point and say that some of them seem to be recovering very, very slowly,” said Carl Zipper, professor emeritus of environmental science at Virginia Tech University . Most of the streams studied didn’t show signs of recovery.

Dissecting the Algae Blooms of Montana’s “Unique Gem” the Smith River
An unusual nuisance is slowly growing into an inexplicable problem for researchers at Montana’s Department of Environmental Quality . For the last five years, a native species of algae called Cladophora has covered large portions of the Smith River, one of the state’s most popular waterways for boating, fishing and recreating. And scientists don’t know why. “It’s just unusual. I don’t know if it’s extreme for the state of Montana as other systems have had Cladophora problems as well. But it’s most unusual due to the lack of land use changes,” said Chace Bell, a water quality assessment specialist with the Montana DEQ.
