        <span class="Apple-tab-span" style="white-space:pre;"> Recently, I just want to analyze the potential density by using the ECCOV4R3 data, and find there is an output called "RHOAnoma", </span><span class="Apple-tab-span" style="white-space:pre;">which means the density anomalies. So I transformed it as the potential density by adding a constant density of </span>1029kg/m3, but it
</p>
<p>
        seem like there is some contradictions especially below the 500m.
