• T anomalies on neutral density much smaller than on depth levels
• Fine scale features present even at ~2km depth

Typical length scale 500-600km
Gaussfit currently not working for points at/near most extreme T anomalies
Need to check fit behavior in some regions (e.g. here)

~2km
~3km
~4km
• Peak (~500-600km) still present deeper down
• Shortest (100-300km) length scales probably a processing issue (maybe proximity to bathymetry or because T anomalies become very small at depth)

Next steps
•Verify gaussfit behavior
•Explore zonal vs meridional dependence
•Investigate time dependence of length scales
•Extend analysis in deep ocean
•Extend analysis to Global ocean
