Station 1
At station 1, transmissivity values near the surface were on average approximately
4.30. This peaks at around 10m depth around 4.32 and remains at similar values at
deeper depths. The range in the values at specific depths is approximately 0.04,
with an overall range of 4.28-
Transmissivity-
Salinity increases in the first 10 meters from 35.0 to 35.2 from there the salinity
decreases to a minimum 34.9 at 27.4 meters. The overall change in salinity from 1.2m
to 27.4 m is negative 0.1.Silicon concentration remains constant, 1.56µmol/L in the
first 10 meters it then decreases at a constant rate to 1.45µmol/L at 27.4 meters.
Phosphate concentration at the surface water is 7.8x10-
Nutrients-
Fluorescence-
Error range: 0.473-
The graph shows that the general trend in fluorescence increases between 0 and 9m by 0.7. For the rest of the water column fluorescence is relatively stable averaging at about 0.445. The graph shows one outlier at 21m with a fluorescence of 0.678.
ADCP Transect-
In terms of backscatter, the ADCP readings are generally consistent apart from the extremities at either end showing high anomalous readings from the turning boat’s wake. On the left side of the diagram tidal flow seemed to exhibit signs of the coriolis force in action as it was being directed southwards to the right at approximately 0.5 m/s.
Evidence of changes in the flow regime can be observed with flow on one side of the
estuary proceeding in a southerly direction down to -
