Public coordinates shown as a random point within 10KM of the true coordinates. True coordinates are only visible to you and the curators of projects to which you add the observation.
private
Coordinates completely hidden from public maps, true coordinates only visible to you and the curators of projects to which you add the observation.
open
Everyone can see the coordinates unless the taxon is threatened.
Pretty much. You want to go to a stretch of rocky shore that has pools at a minus tide. The best pools are ones that are a bit sheltered, usually with some kind of overhang. Look for sponges, bryozoans, hydroids, and other things nudibranchs eat. At this time of year, the best minus tides are around sunset, which is cool b/c more slugs come out at night. Of course, hanging out in slippy tidepools while giant breakers are crashing a few feet away isn't always the best idea.
Some friends and I maintain a map of tidepooling spots along the West Coast: http://g.co/maps/aqtjq. It's incomplete, but shows a bunch of good spots near the Bay Area.
The data quality assessment is a summary of an observation's accuracy. All
observations start as "casual" grade, and achieve
"research" grade when
the iNat community agrees with the observer's ID, where an "agreeing"
identification is one that matches exactly or is of a child taxon of the
observer's ID. For example, if Scott says it's a mammal and Ken-ichi
says it's Homo sapiens, then Ken-ichi agrees with Scott.
the observation has a date
the observation is georeferenced (i.e. has lat/lon coordinates)
the observation has a photo
Observations will revert to "casual" grade if the above conditions aren't met or
the community agrees the location doesn't looks accurate (e.g. monkeys in the middle of the ocean, hippos in office buildings, etc.)
the community agrees the organism isn't wild/naturalized (e.g. captive or cultivated by humans or intelligent space aliens)

So how do you go about seeing these? Are they just hanging out in tidal pools?

Thanks Kueda, I'm heading up to Fort Bragg for the weekend. With any luck I might find a nudibranch. Thanks for the map it is really helpful.
