Q&A: Two pH Sensors – what is causing this difference?
January 2019 Newsletter The data shown above originate from two different pH sensors deployed in the same well-mixed test bath. Both sensors were cleaned, tested, and calibrated before deployment, and were given 24 hours to equilibrate before recording data. So why...
Prototype pH Sensors: Eyes on an Experimental Kelp Farm
December 2018 Newsletter Spanning January to July 2018, two alpha SeapHOx V2s (serial numbers 001 and 002) tracked changes in pH at an experimental kelp farm funded by the Paul Allen Foundation. The purpose of the experiment was twofold: field-test the upgraded...
Basic Maintenance videos for the SeaFET V2
Upgrading to a SeaFET V2 from the original SeaFET is completely internal—aside from the most inaccessible hardware within the instrument, the V2 uses the same housing, sensors, and batteries as the V1. Therefore, the basic maintenance procedures for the V1 and V2 are...
Q&A: What is Causing the Difference between Internal and External pH?
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...
Real-Time Moorings: A Look at Regional Forecasting and Physical Oceanography Research
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...
Q&A: Sudden Increase in Salinity
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...
Salinity Spikes: Sensor or Environment?
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...
Q&A: Profiling CTD Data Spikes
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...
HyperNAV Hyperspectral Radiometer
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...
FRM4SOC Project
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...

What is bioluminescence?
No - that glowing in the water in some marine environments isn't neon toxic glowing sludge - it's bioluminescence! What do the deep-sea Angler Fish and the Crystal Jellyfish have in common? They both emit bioluminescence. Bioluminescence is the ability for an...
What is the UN Ocean Decade?
Did you get a chance to read about the HyperNAV program that we support in partnership with NASA? Sea-Bird Scientific is proud to be part of the NASA PACE Mission, which contributes to the UN Ocean Decade's 7 Outcomes. On December 5, 2017, the United Nations declared...
World Oceans Week at Sea-Bird Scientific: The HyperNAV Program
A New Paradigm for Ocean Color Satellite Calibration The HyperNAV program is part of the NASA PACE (Plankton, Aerosol, Cloud, Ocean Ecosystem) Mission, set to launch in 2024. The NASA PACE Mission is an initiative aimed at helping scientists understand how carbon...
