The reef structure supports colourful soft coral, sponge gardens, and large schools of fish, making it one of the more dramatic offshore snorkel experiences in the Coffs Harbour region.","advanced",null,"published",{"name":20,"amplitude":36,"phase":52,"latitude":13,"model":68,"epoch":69},[21,22,23,24,25,26,27,28,29,30,31,32,33,34,35],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[37,38,39,40,41,42,43,44,45,46,47,48,49,50,51],0.027622191088200427,0.009462986857146504,0.1845781085593742,0.03295453165869725,0.5348428648759238,0.0035332477886009387,0.0037482144690996065,0.004455835941621485,0.11260719994197133,0.0950179336597034,0.05713772374081152,0.02037600129946987,0.012790166756656377,0.13985929400880653,0.010742296303738482,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],293.40998386937645,4.946275042522785,342.3693388859641,294.14988543765924,302.61018541460015,283.17016641085957,200.774380209987,18.71726140342483,295.17276167845904,315.1902759200082,341.3618108885463,278.1607796869888,316.66500301899134,314.28924920925635,340.02644466828986,"EOT20","1992-01-01T00:00:00Z",[71,75,78,82],{"name":72,"description":73,"severity":74,"season_start":17,"season_end":17},"Strong Currents","The East Australian Current can produce strong currents over the reef, requiring good fitness and experience.","warning",{"name":76,"description":77,"severity":74,"season_start":17,"season_end":17},"Boat Traffic","Marsh Shoal is an offshore reef accessed by boat; vessel traffic in the area poses a hazard for snorkelers at the surface.",{"name":79,"description":80,"severity":81,"season_start":17,"season_end":17},"Deep Water","Depths range from 12 to 25 metres, making this site unsuitable for beginner snorkelers and requiring good buoyancy control.","danger",{"name":83,"description":84,"severity":85,"season_start":86,"season_end":87},"Ocean Swell","Exposed offshore location means ocean swells can create challenging conditions, especially in winter and spring.","caution",5,10,{"directions":89,"parking":90,"facilities":91,"fees":94,"access_method":95},"Marsh Shoal lies approximately 2 km offshore from Korora Beach, near Coffs Harbour.
