Description Not Available
Coastal marine environments are important links
between the continents and the open ocean. The coast off
Mangalore forms part of the upwelling zone along the
southeastern Arabian Sea. The temperature, salinity, density,
dissolved oxygen and stable oxygen isotope ratio (d18O) of
surface waters as well as those of bottom waters off coastal
Mangalore were studied every month from October 2010 to
May 2011. The coastal waters were stratified in October and
November due to precipitation and runoff. The region was
characterised by upwelled bottomwaters in October, whereas
the region exhibited a temperature inversion in November.
The surface and bottom waters presented almost uniform
properties from December until April. The coastal waters
were observed to be most dense in January and May. Comparatively
cold and poorly oxygenated bottom waters during
the May sampling indicated the onset of upwelling along the
region. d18O of the coastal waters successfully documented
the observed variations in the hydrographical characteristics
of the Mangalore coast during the monthly sampling period.
We also noted that the monthly variability in the properties of
the coastal waters of Mangalore was related to the hydrographical
characteristics of the adjacent open ocean inferred
from satellite-derived surface winds, sea surface height
anomaly data and sea surface temperatures.
