The figure above originates from a single Shallow SeaFET V2 pH sensor, which produces two pH values (Internal pH and External pH) from two separate reference sensors. The black X’s indicate pH validation samples. While environmental conditions affect each the...
An ocean mooring can help with more than publishing research papers. When sensors can talk to the buoy controller, and the buoy controller can call home, real-time moorings can provide useful data for short-term regional storm forecasting. Such was the case with...
November 2018 Newsletter The figure above originated from an SBE 37-SMP MicroCAT moored CTD deployed in shallow seawater. On day 38, the salinity data appears to jump from a near-zero value, steadily increasing until around day 43, where it stayed around 30psu. Nearby...
These data show a subtle problem that is producing “fuzzy” salinity and oxygen data. While the overall shape of the profile appears reasonable, small spikes are present throughout the CTD cast. The black lines encompass a particularly strange spot where both salinity...
October 2018 Newsletter The four figures above come from the same 9plus CTD profile. As you can see, massive spikes punctuate the data stream and wreak havoc on data quality. While post-processing can filter out some spikes, they can also affect the CTD’s in-situ...
As remote sensing satellites orbit Earth, Sea-Bird Scientific and NASA are developing a tool to drift with ocean currents. The HyperNav, a combination of hyperspectral radiometers and a Navis profiling float, provides in-situ calibration and verification for ocean...
Scientists from around the world donned white jumpsuits and entered an unusual room. Inside, all furniture and walls were painted black, and very particular lamps emitted light directly into a device harnessed to a dark table. This was Laboratory Comparison Exercise 2...
Positive pressure and sticky mats shun light-scattering dust from a room in Philomath, Oregon—the site of a new brand new radiometer calibration facility. As Sea-Bird Scientific’s facility in Halifax, Nova Scotia (formerly Satlantic) shuttered its doors, radiometer...
The new HydroCAT-EP V2 has increased durability for long-term moored deployments in the open ocean, coastal, and freshwater coastal environments. Enhanced sealing surfaces throughout the instrument provide greater reliability in inhospitable conditions, ensuring high...
The new HydroCAT-EP V2 is now available. Although it’s practically identical to its predecessor, we’ve made some useful mechanical upgrades to this new version. Watch this Sea-Bird University session to learn how to use, maintain, and process data from our latest...
Art Pedersen, founder of Sea-Bird Electronics, passed away on October 8th, 2021. His designs are firmly cemented into Sea-Bird’s CTDs, and he leaves behind profound impacts on how scientists make measurements in the ocean. Dr. Norge Larson, former president of...
