Q&A

How are water quality sondes mounted to moorings?
When measuring near the surface, water quality sondes can be housed inside a slotted deployment pipe that is threaded directly to the bottom instrument well on the buoy hull. This allows instrument access for periodic cleaning and calibration without having to pull the buoy out of the water. If the project requires measurements at depth or at multiple depths, NexSens offers instrument clamps and mooring cages for mooring lines, as well as bottom platforms when sondes need to be bottom referenced instead of surface referenced.
How do I connect sensor cables to the data buoy?
For customer integrations, cables can be run through one of six ports on the passthrough data well lid and secured with a supplied cable gland. The backside of the cable gland should be filled with epoxy or sealant to prevent water ingress. Alternatively, NexSens can supply a waterproof bulkhead connector with mating pigtail for splicing with user-supplied sensor cables. This allows for a quick disconnect of the cable at the lid. When using an X2-CB or X2-CBMC data logger on a NexSens integrated system, all supplied sensor cables are terminated with mating UW plug connectors or MCIL-8-FS connectors.
How do I mount a Doppler current profiler to the data buoy?
The mounting for an acoustic Doppler current profiler (ADCP) is instrument-dependent. NexSens offers several ADCP mounts for Nortek instruments, including the Aquadopp and Signature Series ADCPs. The mounts must be designed in such a way that the acoustic beams are unobstructed by the buoy and mooring. Custom mounts are also available based on project-specific needs.

The Coral Reef Early Warning System (CREWS) The Coral Reef Early Warning System (CREWS)

The Coral Reef Early Warning System (CREWS)

Corals around the world are under threat. The buoys of the Coral Reef Early Warning System (CREWS) help face that threat, providing the entire world with weather patterns and data about climate change from their home in the Caribbean Sea. Since June 2018, a new, state-of-the-art oceanographic buoy has added ocean state and weather data in near real-time to the CREWS system—all accessible from a computer or smartphone. A better understanding of more threatened regions Installed by the Central Caribbean Marine Institute (CCMI), which runs the CREWS system, the CCMI team helped describe the challenges the CREWS system needs to tackle.

Liberty Island Restoration Project Liberty Island Restoration Project

Liberty Island Restoration Project

In 2010, a design for the Liberty Island Restoration Project was completed and implemented, creating open water channels, emergent tidal marsh lands and floodplain habitats to sustain water fluctuations. The work was done in an effort to help wildlife living in the California Delta as well as fish species including delta smelt and Chinook salmon. But beyond just putting new marshes in place, it was important for those working on the restoration to confirm that all the work was making a difference. Doing something like that involves monitoring conditions around the area to see how its water quality and habitats are improving. Researchers at the U.S. Geological Survey’s California Water Science Center help in those monitoring efforts and oversee a network of data logging devices that cover the delta. It relies on a number of continuous monitoring stations that gather data on the area’s water quality, and has been collecting data for the last few years. Contributing to an ongoing effort

Developing Alaska Buoy Platform Developing Alaska Buoy Platform

Developing Alaska Buoy Platform

Recent studies into global climate change have identified an increase in Arctic warming rates. These are linked to increased trends toward more sea ice loss that are leading many to anticipate the Arctic will become a more popular shipping route. Coinciding with this expected expansion in use, agencies in the U.S., including the National Oceanic and Atmospheric Administration, are preparing for more operations in the Arctic. For NOAA, that means testing and developing new ways to monitor in the region’s waters. Since the Alaskan offshore is a new locale for the observation network, researchers at NOAA are working out the kinks of monitoring there before any expensive sensors are placed in the Gulf of Alaska. They have a straightforward solution for long-term stations ready to go, and have turned their attention toward developing short-term platforms that can perform reliably in the harsh region.
