Methods
At each of the 16 stations, one corner of a 10 x 10 m plot was staked, and 12 sampling points were selected by use of random numbers on a grid made up of 2 x 2 m squares; the location was determined by use of a compass and graduated 2 m pole. At each point, presence or absence of epibenthic fauna and flora species were observed within a 1/4 m2 quadrat, giving frequency data for each of the documented species (no. quadrats out of 12 in which a species was observed).
Seagrass was further sampled by throwing a 1/16 m2 quadrat into the area 3 times, and collecting seagrass within the quadrat after shearing it at substrate level. The seagrass was bagged, subsequently shaken to remove free water, and then weighed fresh. These weights include water, seagrass blades and attached epiphytes. Widths of thirty-five blades, selected randomly, were measured to the nearest 0.5 millimeter, and lengths of the longest-appearing 15 blades were measured to the nearest millimeter.
A portion of the 1969 file
Station Data for Epibenthic Flora and Fauna 1969, 1994, 2015
– BATH FREQ 69 (.xls file)
– BATH FREQ 94 (.xls file)
– BATH FREQ 94 – to be added
These are the initial working files; they still need to be “cleaned up”, giving proper species names etc.
