Mixed layer depths from R/V Tangaroa cruise 61TG_3052 in the Southern Ocean in 1999 (SOIREE project)
SOIREE Mixed Layer Depth<br> The mixed-layer depth is defined as the maximum depth at which the sea-water<br> density is less than the density at 5m + 0.1 kg m-3. This picks up the top of<br> the seasonal pycnocline, but is insensitive to the weaker stratification that<br> oc...
