This protected sanctuary boasts excellent coral cover and clear, nutrient-rich waters that attract a dense concentration of marine life. The reef features sloping coral bombies, sand gutters, and a shallow reef edge ideal for snorkelers. It is known for encounters with large bumphead parrotfish grazing on coral, schools of trevally and barracuda, and frequent sightings of white-tip reef sharks. Its protected status has helped maintain healthy coral communities, making it a rewarding offshore snorkel destination for those seeking a less crowded reef experience.","intermediate",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.0257214148292867,0.021756061212184846,0.3243009751888653,0.09329970196979054,0.6101004289743249,0.013051106874049118,0.006803285967523029,0.008941038883531429,0.19503777501834602,0.16003235647462632,0.09674097735648693,0.027594240686608797,0.007556339798440587,0.33505256421812296,0.02639075554505481,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],323.149672759471,54.59738953717057,36.30869228337013,298.1668878188357,344.82191756858725,282.08440577882243,31.82695525533411,40.39826732175782,327.9986330103543,9.940911564397748,32.73937775790313,350.11620297676393,319.5621523186633,303.81351515907653,278.44741334371105,"EOT20","1992-01-01T00:00:00Z",[110,114,117,120],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Ocean currents","The reef is exposed to open ocean currents.
