Description 390-401
In Little Andaman Island Water nutrient levels of silicate (0.19 – 5.88
µM); inorganic phosphate (0.02 – 0.93 µM); nitrate (0.103 – 4.91 µM); nitrite
(0.004 – 0.130 µM) and POC (1.13 – 4.95 mg C l-1) were comparable to those
recorded in the other reef environments of India. Sediment macronutrients viz. nitrogen (15 kg/ha to
43.0 kg/ha), phosphorous
(1.0 kg/ha to 10.0 kg/ha) and potassium (45.0 to 137.0 kg/ha) recorded from the
different locations of the Little Andaman island showed significant variation
among the stations (0.05%). Sediment trace elements viz. iron (5.24 – 10.2ppm),
manganese (1.85 – 5.69ppm), zinc (0.67 – 2.55ppm) and copper (0.19 – 1.17ppm)
showed significant variation (ANOVA 0.05%) among different locations. Higher
population density of actinobacteria in the water samples was recorded at
station 4, Chandra Nallah coast (17 × 10-3 CFU/g) and the lower density
in the waters of station 10, South Bay (1.2 × 10-3 CFU/g). In the
sediments, maximum population density (9.7 x 10-4 CFU g-1)
was recorded in Capel Rock (station 9) while the minimum (0.8 x 10-4
CFU g-1) was recorded in Antegeleda (station 12).
