 ## Common Use Cases
 
-- Generating Seafloor Age and Spreading Rate Grids Through Time
-  ![Figure: age-and-spreading-rate-200ma.png](https://raw.githubusercontent.com/GPlates/gplately/375-update-main-readme-and-seafloorgridsipynb/Notebooks/NotebookFiles/age-and-spreading-rate-200ma.png)
-- Plotting Paleomaps with Cartopy
+- [Generating Seafloor Age and Spreading Rate Grids Through Time](https://gplates.github.io/gplately/latest/notebook-html/10-SeafloorGrids.html)
+  
+  Adapted from code written by Simon Williams, Nicky Wright, and John Cannon for gridding general z-values onto seafloor basin points using GPlately.

+- [Plotting Paleomaps with Cartopy](https://gplates.github.io/gplately/latest/notebook-html/02-PlateReconstructions.html)
+
+  GPlately can use Cartopy to plot paleomaps. The figure below shows a comparison of paleomaps produced with the Müller et al. 2019 and Müller et al. 2016 plate reconstruction models.

-- Rasters Reconstruction
+
+- [Rasters Reconstruction](https://gplates.github.io/gplately/latest/notebook-html/06-Rasters.html)
+
+  GPlately can be used to reconstruct raster datasets back through geological time. The figure below shows the ETOPO1 relief raster reconstructed to 50 Ma.

-- Locations Reconstruction 
+
+- [Locations Reconstruction](https://gplates.github.io/gplately/latest/notebook-html/03-WorkingWithPoints.html)
+
+  GPlately can be used to calculate the paleo-coordinates of locations. The figure below shows the reconstructed locations of Jurassic foraminifera.

-- Calculating Motion Path
+  
+- [Calculating Motion Path](https://gplates.github.io/gplately/latest/notebook-html/09-CreatingMotionPathsAndFlowlines.html)
+
+  GPlately can generate motion paths to illustrate the trajectories of tectonic plates through geological time, and create flowlines to track plate motion from spreading features such as mid-ocean ridges.
