As Garmin put this week firmware updates to ALL marine chart plotters,
almost just to include the Extended DSC NMEA Message (DSE), it would
be nice if anybody expert in NMEA could tell us an explanation of this
message.

Thanks

Not quite ALL. There wasn't an update for the 162.

Well, I forget to say "almost" ALL "current" marine chartploters, as
the 162 (and my old GpsMap130) are listed in Garmin WP as
"discontinued" models. I do not care about this, because I have a
"new" GpsMap 276C.

I did a bunch of googling.

1. The DSE sentence is output by the radio and received by the chartplotter.
I'm going to
conjecture that it has more precision than the DSC sentence. What gets
transmitted
over the airwaves by DSC only has position to on minute of lat/lon.
While that's probably
fine for somebody 100 miles offshore, in coastal water it's not good
enough. I'm conjecturing
that the DSE sentence is part of the solution to that.

2. There are a LOT of porn sites with NMEA and DSE in their pages.

I'm sure NMEA will be using BDSM, PEDO, etc. for acronyms in the near
future....(c;
