Depth Profile

What This Page Does

This page plots vertical profiles of δ18O, δD, d-excess, temperature, or salinity against water depth. Filtered reference data and an optional browser upload can be shown together.

Basic Workflow

Select reference data and a Profile parameter.
Optionally upload a CSV, XLSX, or XLS file. The selected parameter and Depth_m are required for a profile; coordinates are optional for the map.
Set the sidebar filters and select Apply settings to update the view.
Choose whether to show unfiltered background data.
Adjust the depth range, horizontal-axis scale, figure size, fonts, and ticks.
Inspect the profile and sampling map, then download a PNG figure if needed.

Main Controls

Show background data
Profile parameter
Depth range
Axis scale
Figure width / height
Tick font size / Label font size

Map controls / Map style
Show uploaded data without Month information — controls whether upload rows without a valid month remain visible in the profile.
Uploaded data quality check — lists uploaded rows that trigger the current quality-flag criteria.

Outputs

Depth profile plot
Sampling-location map when valid longitude and latitude are available
Downloadable PNG figure
Expandable table for the filtered data used by the current view

Notes And Limitations

The selected parameter and depth must both be valid numeric values. dD and d-excess may have many missing values; excluded-row counts are reported.
Gap rows are inserted so lines do not connect unrelated station/date groups.
Uploaded profiles are grouped by rounded coordinates when coordinates are available. With Month values, they are coloured by four month bands (1–3, 4–6, 7–9, and 10–12); rows without a valid month use the selected upload style when Show uploaded data without Month information is enabled.
Browser uploads exist only for the current browser session. They do not modify reference datasets or persistent User Excel data.
Long filter-condition titles are wrapped in downloaded images.
