Abstract:
MOBR is the study of the synergistic effects of meteorological,
oceanographic, biological, and radiological parameters on each other to
monitor the state of the atmosphere, hydrosphere, lithosphere, and biosphere
in a particular marine environment. In our work, 24 parameters of MOBR
data were collected to assess the marine ecosystems around Madras nuclear
power plant. The results demonstrated the significant influence of sea level
pressure on surface air temperature, its role in wind formation, control of
wind affecting sea current velocity, and subsequent effects on the cover
percentage of living and non-living organisms, biodiversity, as well as the
seasonal behavior of Uranium 238 (U-238) across various spheres. The
observations highlighted a key aspect of the study area, which was
predominantly covered by high sand ratios (76 and 88% during the premonsoon
and monsoon seasons, respectively). This sand dominance
impacted biodiversity significantly. Interestingly, the highest values of U-
238 were recorded in sediment, dust, crabs, and green algae during the
monsoon season, with the exception of fish. This pattern was a result of the
prevailing sand dominance. This study is considered the first attempt to
infer the interactions between meteorological, oceanographic, biological,
and radiological parameters (MOBR) to monitor marine ecosystems.
