Great White Shark observed off our observation vessel as part of annual Sharktober naturalist tours lead by David McGuire, Sea Stewards. Each year we conduct whale and wildlife watching tours to the Farallon Islands to watch for sharks and discuss the entire ecosystem.
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)
Comments & Identifications
Wow, you guys really go that far out to sea?
These sharks aggregate off the Farallon Islands each fall. In the early winter they travel over 2000 miles west and return each year.
Cool. The Farallons are about 228 km to the northeast of these coordinates, though, FYI.
