C. Pattiaratchi et al., ESTIMATES OF WATER-QUALITY IN COASTAL WATERS USING MULTI-DATE LANDSATTHEMATIC MAPPER DATA, International journal of remote sensing, 15(8), 1994, pp. 1571-1584
An evaluation of Landsat Thematic Mapper (TM) data for the routine mon
itoring of surface chlorophyll concentration (C) and Secchi disk depth
(SDD, a measure of the water clarity) used Cockburn Sound as a study
area. Multi-temporal empirical algorithms to predict these parameters
have been developed from the atmospherically-corrected satellite-recei
ved radiance and field data collected at the time of the satellite ove
rpass. Highly significant, predictive algorithms for the surface C (ra
nge: 0.2-2.7 mug l-1) and SDD (range: 4-15 m) were obtained using band
s 1 and 3 of the Thematic mapper. It is shown that a high confidence m
ay be placed on the predictions using these algorithms and therefore i
t offers a cost-effective tool for complementing regular monitoring pr
ogrammes.
