I’ve been looking at a lot of data lately. Visions of data are dancing in my head. Why? Because often, an oceanographic sensor will just crap out. And I must find that bad data and banish them from my analysis.
Every sensor has the potential for a problem. Water velocity, temperature, oxygen, nitrate and conductivity have all been known to rebel. THE STRUGGLE IS REAL. Even though they are super useful for computing seawater salinity and density when combined with a with temperature-sensing thermistor, conductivity cells were the worst offenders. Maybe it’s because they are delicate glass tubes that are just trying to measure how well electricity conducts through seawater? Or maybe it’s because they are just jerks. Nonetheless, after looking at literally 1000’s of data records I’ve gone ahead and categorized some of the most common ways I saw conductivity go wild so you don’t have to. YOU’RE WELCOME SCIENCE.
