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.

Digital Mayfly Data Logger Sensor Stations Monitoring Watersheds
For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed. “ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.

Solar and Wind-Powered, Algae Tracking Boat Trialed in Florida
Time is of the essence when it comes to tracking algal blooms, and people everywhere are looking for solutions. In Florida, scientists from Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) recently trialed a solar-powered, algae-tracking sail boat developed by Navocean , Inc. Dr. Jordon Beckler of Florida Atlantic University (FAU) directs HBOI's Geochemistry and Geochemical Sensing Lab and spoke to EM about the trials and the boat. "This boat is so amazing when you see it in action," remarks Dr. Beckler. "Navocean originally contacted me a few years back about a demonstration when I was over at my previous institution in West Florida, and we brainstormed some scenarios for employing the boat for harmful algae bloom monitoring.

CICHAZ Biological Field Station Provides A Unique Educational and Research Experience in Mexico’s Huasteca Region
The story of the Centro de Investigaciones Científicas de las Huastecas "Aguazarca" (CICHAZ) Biological Field Station, a member of the Organization of Biological Field Stations ( OBFS ), starts with Dr. Gil Rosenthal, Professor of Biology and Chair of Ecology and Evolutionary Biology at Texas A & M University . Rosenthal has worked in the Huasteca region of Mexico since 1994 and for years kept his research equipment at a local ranch/hotel with the dream of one day having a field station where he could run experiments with collaborators and students. Since 2005, Rosenthal has been the Co-Director of the field station along with his wife, Dr.
