Surveys and oceanographic measurements investigated the patch dynamics of macroalgae in the Ningaloo lagoon. Surveys of benthic macroalgae were conducted at three seaweed dominated bed sites, separated by 1 - 5kms, at Coral Bay and Tantabiddi. Scuba divers randomly placed six replicate quadrats on the benthos sites between 1m and 5m depth. All attached macro algae larger than 1cm was harvested by hand, washed and sorted into genus level or higher categories. Samples were weighed to the nearest 0.1g. Height of transects were recorded and samples analysed for seasonal biomass estimated. This study compared macroalgal biomass to available data on monthly variations of sea temperature, rainfall, light, wind-driven upwelling and significant wave height. Data sources included submersible temperature loggers, monthly rainfall totals at Ningaloo Station and data from the Ningaloo Weather Station at Milyering, and an offshore wave rider bouy measuring daily significant wave heights.
