SO14 3ZH Tel: +44(0) noc.ac.uk Typical length scale km Gaussfit currently not working for points at/near most extreme T anomalies Need to check fit behavior in some regions (e.g. here)

SO14 3ZH Tel: +44(0) noc.ac.uk ~2km ~3km ~4km Peak (~ km) still present deeper down Shortest ( km) length scales probably a processing issue (maybe proximity to bathymetry or because T anomalies become very small at depth)
