Data processing

Data are split into spatiotemporal surface and bottom bins based on data source type, either buoy, vertical, or flowthrough.
Profile types:

• Buoy: averaged into 1 hour bins

• Vertical: split into directional casts. Upcasts are retained (when available) and a unique profile identifier, like a station ID or coordinates, was assigned to split into separate profiles.

• Flowthrough: data were put onto a regular grid and averaged into hourly spatial bins

Depth bins:

• Surface: averaged observations above climatological mixed layer depth (per profile)

• Bottom: averaged observations 10 meters above bathymetric seafloor
