How it works - wildbook sevengill shark

It's one of the projects i am working on. It's about broadnose sevengill sharks (Notorynchus cepedianus) in USA and South Africa.
I found that it will be a good idea to record what i am doing and explain better how Ocean Sanctuaries (https://oceansanctuaries.org/) with the wildbook (http://www.wildbook.org/) is helping on Shark Conservation.

The position i have is Pattern Recognition Expert on Sevengill Shark Identification.
But before i explain further what i am doing (the mark spotting, fixing the gender, and mark them as new individuals or match them with other same individuals), i have to say that it's an easy job if you know what to do.
And i am enjoying this because i already know because i have used I3S software before for the identification of individuals of Sand tiger shark (Carcharias taurus) in South Africa.
Now are the steps you can see in the video:
1. First of all, I have to log in with my credentials.
2. I am doing it by an area, so in this video, you see that i am looking for "San Diego" encounters.
3. I am checking what was the last "alternative Id" i have put, so, i can continue from where i stopped last time.
4. Then i am re-arranging the date because i have started from the oldest encounters and i continue to the newest encounters.
5. When i find where i stopped, i am entering the next in the row encounter.
6. I am adding the "alternative ID" so i won't forget what was the previous.
7. I am fixing the name and gender (if necessary).
8. If it has more than one photo of the same view (i.e. left), i find the better photo and i press the lines icon on the bottom-right of the photo and then i press the "Spot marking".
(Here if an encounter has both sides i must do "Spot marking" on both sides before i do step 16)
9. When spot marking page has been loaded, i select the region (which is the head), if it needs i am turning the photo so it can be as horizontal as can be the head.
10. Then i am choosing the top of the 1st gill, the top of the eye, the lower corner of the nostril and the lower corner of the mouth.
11. After choosing all these, i must start to mark the spots (the black ones). I try to mark the bigger spots, or the spots which give like a sign (for example three dots in the row, or making symbols like a cross, etc), or big patches.
12. Then i press "Save" and "Start ScanTask".
13. In the page it is showing, i have to remember the number of the encounter (or write it down) and "Go to sharkGrid".
14. In "sharkGrid" i have to view the encounter and check the patterns if they match with other encounters in the same date or a different date.
15. I have to check both "Modified Groth" and "I3S".
16. If it's not matched with another encounter, i am returning back to encounter page and i am going to edit the "Identity" and create a new "Unmatched first encounter" and "Create Marked individual" with the code of the area (example: for San Diego Coastline i use SDC), the date of the encounter (example: 2013), and four-digit number (i use the four-digit number of the alternate id, example: 0045). So the final encounter ID will be like this: SDC2013-0045.
17. Now if i find another matched encounter, i open the other encounter on a different tab on my browser and check the date. If it's older than this encounter i did "Mark spotting" now, i am copying the "Marked individual number" of the oldest and then i am going to this encounter i just did "Mark spotting" and edit the "Identity" box and put the "Marked individual number" of the oldest. Then i choose if it was "Pattern Match" or "Visual Inspection" and i save it.
18. I am reloading the page, to be sure that the "Marked Individually number" is shown and i am pressing it to see if all the recorded encounters are shown inside.
19. That's it. Then i continue to the next encounter.

I love helping with shark conservation projects. And i can't wait to see the results when i finish with the database.
