Spectral characteristics of nine coral species (
$\bullet$ This study attempts to analyse the spectral characteristics of nine different coral reef species species (
$\bullet$ Results revealed that several coral species either fall under the broad category of Brown mode or Blue mode. Brown mode of corals was identified by a triple peaked pattern exhibiting local maxima or shoulders near 575, 600 and 650 nm. The blue modes of corals were identified by a plateau-like shape between 600 and 650 nm. The non-coral species such as seagrass and sea moss can be identified by a peak between 550 and 560 nm.
$\bullet$ It can also be noted that, irrespective of water column conditions; (i) all the coral reef benthic compositions tend to have its reflectance minimum around 674 nm (This phenomenon is due to the strong absorption of chlorophyll in that portion of EMR). (ii) Influence of water column can be seen in the rise of magnitude in the longer wavelengths of EMR for the measurements recorded based on exposed condition.
$\bullet$ Results exhibited that, most of the coral reef benthic compositions falling under either Blue mode or Brown mode of corals and the patterns of spectral signatures exhibited in this region are matching with existing global signatures.
