   Imported NOS data from snapshot 2020-12-23.  This includes a large number
   of new currents because harmonic constants for currents are now available
   through MDAPI.

   The currents are a clean break from previous years.  No data or metadata
   were carried over.  Coverage of the Salish Sea is mostly consistent with
   what was imported 2019-06; a few stations and depths were dropped, but
   the rest are equivalent.

   Cleaned up more typographical style issues in station names.

   Dropped a few more stations that appear to be in Canadian waters.

   Made a serious effort to harmonize the states of all tide and current
   stations with what Google Maps showed for the coordinates.  The resulting
   assignments may be surprising when the state line runs between the named
   landmark and the location of data collection.

   The following waters are especially problematic for assigning states:
   - St. Marys River
   - Savannah River
   - Pocomoke Sound and River
   - Delaware Bay and River
   - Everything around Long Island
   - Piscataqua River
   - Columbia River
