- Lake Turnover Layer Density Gap Tool Two-layer density-gradient sign only; does not predict lake turnover timing or wind mixing.
- Littoral Shoreline Complexity Factor Tool Shoreline development relative to the circumference of an equal-area circle, without changing map resolution.

- Water Column Cast Depth Zero Shift Calculate signed cast depth relative to an explicit depth-zero reference without applying pressure-to-depth conversion.
- Water Column Integrated One Layer Tool Trapezoidal depth integral with concentration varying linearly across one layer.
- Water Column Layer Average Average supplied layer values by nonnegative layer thickness for a positive finite total water-column depth.
- Water Column Layer Overlap Tool Intersect supplied downward-positive depth intervals in one datum.

- Waterbody Salinity Reference Tag Preserve an explicit waterbody salinity transcription and reference scale without converting scales.
- Waterbody Volume Layer Contribution Tool Estimate one layer volume with a trapezoidal area-depth model, not an exact arbitrary-basin volume.
