Tiahura


Localisation
Tiahura is located on the North coast of Moorea, in the Society archipelago. 
17°28.940'S/149°53.985'W (conversion DM/DMS)
The thermometers are distributed along the radial (at -1 to -50m depth, see positionning schema below).
The multiparameter probe SB16 is at -25 mètres and the wave probe is at -35m.


Programs
The Polynesia Mana since 1998 (orange pin on the map)
The MPA from PGEM since 2004 with the MPA of Tiahura (black dot on the map)
The Temporal Layout of Populations and Communities or ATPP since 1990
The Radial of Tiahura since 1971
The Coral recruits survey since 2000 (yellow dots on the map)
The nutrients analysis since 2008

Icon Corail 35px The analysis of the coral cover is done using several methods:
Photo quadrat coral transect, Seascape photographic assessment and Photogrammetry (Polynesia Mana). Here are the photo quadrats and to the
