Unlike its neighbours Clerke and Imperieuse, Mermaid Reef has no dry land — it is a wholly submerged atoll ring with a shallow turquoise lagoon at its centre and sheer vertical drop-offs plunging to depths of over 500 metres. The reef protects over 200 species of hard coral and more than 530 species of fish, making it one of Australia's finest examples of a continental-shelf atoll. Accessible only by liveaboard cruise from Broome, this remote marine park offers world-class drift snorkelling over vibrant coral gardens and along dramatic reef walls in gin-clear waters.","intermediate","published",{"name":58,"amplitude":74,"phase":90,"latitude":22,"model":106,"epoch":107},[59,60,61,62,63,64,65,66,67,68,69,70,71,72,73],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[75,76,77,78,79,80,81,82,83,84,85,86,87,88,89],0.016621489692458986,0.013670540707370544,0.22683420762300577,0.1396243655134518,0.8962977466515649,0.004173946635395861,0.010083302077220522,0.004226307628167113,0.1608937759299871,0.14240111985120388,0.06594774603994025,0.03215087647379989,0.010504303971749765,0.5063788927050427,0.02558000954104217,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],356.77538708900545,179.96934163122103,167.99845494025098,113.3591908767462,56.85399353294509,243.99008951847827,354.5300177655725,8.041609586033049,30.117573332369115,158.7994199663081,165.1009981289032,148.68693941105468,353.80297628428264,115.01469883461411,127.11994982226051,"EOT20","1992-01-01T00:00:00Z",[109,114,118,121],{"name":110,"description":111,"severity":112,"season_start":36,"season_end":113},"Strong tidal currents through gaps","The atoll channels experience powerful tidal flows that can sweep snorkelers away from the reef wall into open ocean.","warning",12,{"name":115,"description":116,"severity":117,"season_start":36,"season_end":113},"Remote location – no emergency services","Mermaid Reef is 280 km offshore with no land, no medical facilities, and no cell reception.
