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 Sub 2 & Manta 2 sondes, and In-Situ TROLL 9500 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.

Restoring Native Brook Trout in North Carolina
The North Carolina Wildlife Resources Commission ’s Inland Fisheries Division has been working to restore brook trout in the state. Coldwater research coordinator Jacob Rash, who works with the brook trout team technicians on this project, spoke to EM about the work. “In North Carolina, brook trout are our only native trout species,” explains Mr. Rash. “With that come biological and ecological considerations as well as cultural importance. A lot of folks here grew up fishing for brook trout with their relatives, so it's an important species that we work to try to conserve. We've done quite a bit of work to figure out where those brook trout populations are and what they are, in terms of genetics.

Robotic Fish May Reduce Live Fish Testing Near Hydroelectric Plants
Each year in Germany, as many as 450,000 living fish undergo live animal experiments to test how fish-friendly hydroelectric power plants in the country are. The idea is to discover how readily the fish can move through hydroelectric turbine installations in order to ultimately reduce mortality rates. Of course, subjecting live fish to a potentially deadly test to save others is a bitter irony. And it's one that a team of scientists from the RETERO research project hopes to eventually mitigate with a robotic fish for testing. EM corresponded with Olivier Cleynen and Stefan Hoerner from the University of Magdeburg about the complex flow conditions that set the parameters for the project.

Mobile HAB Lab, Citizen Scientists Building Awareness
News stories about dogs getting sick from harmful algal blooms (HABs) in lakes have caused worry among members of the public this summer more than once. But Regional Science Consortium (RSC) Executive Director Dr. Jeanette Schnars and a dedicated team are bringing awareness about HABs to the public with the Mobile HAB Lab. “We just launched the HAB Citizen Scientists program this year,” explains Dr. Schnars. “It helps us work with people, especially people who spend time at marinas frequently, that are out there all season long.” The season for boaters at Presque Isle, where RSC is located, starts in mid-May and usually continues through the beginning or middle of October.
