May 2019 Newsletter ISFET-based pH sensors have been used to measure pH in industrial settings for years (do you know the pH of your last beer?). It’s the adaptation of this technology for measuring ocean pH that makes the SeaFET V2 and SeapHOx V2 novel tools for the...
April 2019 Newsletter Sea-Bird Scientific’s line of ISFET pH sensors only communicate via RS-232. However, savvy integrators can utilize the SBE 44 Underwater Inductive Modem as the link between the SeaFET/SeapHOx and an existing inductive modem mooring, providing...
March 2019 Newsletter The data shown above come from a SeapHOx V2 (red) and Deep SeapHOx V2 (blue) deployed next to one another in a dynamic estuarine environment. Regular pH validation samples were collected throughout the time-series. According to the 0.05 pH...
The data above originate from a SeaFET pH sensor connected to a flow-through system that should provide stable, consistent data. As you can see, the Internal pH value experiences a dramatic drop in pH and a subsequent increase in noise midway through data collection....
There are plenty of pH sensors on the market, with some recent additions showcasing novel technology and design. Among Sea-Bird Scientific’s holdings, we offer 7 different pH sensor models divided amongst 2 different technologies: ISFET and glass-electrode sensors. To...
Back in May 2018, Sea-Bird Scientific upgraded the SeaFET™ pH sensor to the “SeaFET™ V2”, improving upon the performance of the original SeaFET™ while retaining the same underlying ISFET sensor technology. The SeaFET™ V2 improves upon the original SeaFET’s...
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...
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...
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...
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...
Hands Off and High-Quality Data: Using the HydroCAT-EP V2 to Get the Full Picture of a Dynamic Aquatic Ecosystem “King County, Washington’s mooring program is designed to collect continuous oceanographic and meteorological data every 15 minutes in Central Puget Sound....
We are excited to celebrate Pride Month in 2023 with our supporters, partners, and associates. Pride is a special month to us, as it gives us an opportunity to reflect on our commitment and support to the LGBTQIA+ community, something that is integral to the culture...
We are excited to celebrate International Women in Engineering Day on June 23. This day is meant to celebrate women in STEM, and provide an opportunity to highlight women in engineering fields, who are still very much under-represented. In fact, according to the...
