Some metadata in the Sayre et al 2019 global shoreline database look suspicious

[dbuscombe-usgs]

We have been using a reference shoreline database from Sayre et al. 2019 (https://doi.org/10.1080/1755876X.2018.1529714) which comes with a number of valuable metadata variables such as tide range and significant wave height

However, I am suspicious about the significant wave height estimates for the Pacific Northwest region, which seem to be biased very low:

I will now be checking the validity of the Hs data in this region and others.

I believe the tidal ranges are correct, and are shown here for reference
