v2.0

This release significantly reduces running time and memory usage.

Other changes include:

• Can generate costly distance grids faster using a lower internal resolution (eg, 1 degree).
  • Then upscale to a higher resolution (eg, 0.1 degrees).
• Can specify maximum memory usage (to avoid out-of-memory crashes).
• Input parameters easier to configure.
  • Eg, specifying age grid filename format (where time is in the filename and how many decimal places).
• Can specify a non-zero reference frame (eg, if age grids are in a non-zero mantle frame).

v1.1

This release contains the sediment thickness workflow with an updated calibration.

Here, the relationship for sedimentation rate and thickness was based on the calibration of the:

• age grid from Zahirovic et al. (2022), or 'Muller-2019-Young2019-Cao2020' evolving seafloor age grid from the GPlates 2.3 sample data, and
• present-day sediment thickness of Straume et al. (2019), also known as GlobSed.

v1.0

This release contains the original sediment thickness workflow from Dutkiewicz et al. (2017).

The relationship for sedimentation rate and thickness was based on the calibration of the:

• age grid from Müller et al. (2016), and
• present-day sediment thickness of Divins (2003) incorporating additions by Whittaker et al. (2013)(data) and Wobbe et al. (2014)(data) for the Southern Ocean.

It also includes updates to make this code compatible with Python 3
