Figure 2. Variations in (a) temperature, (b) salinity, (c) O 2 , and (d) NO 2 in the upper 1 km
of the water column along the Goa transect (location shown in the inset) during 1-6 December,
1998.
We present here data covering the annual cycle, collected at a quasi time-
series station located over the inner shelf off Goa, and property distributions
across the same segment of the shelf during the two monsoons. The time-series
station, designated as the Ca ndolim T ime S eries (CATS), has been sampled by
us since 1997. With a water depth of around 28 m, the CATS site (15 o 31'N,
73 o 39'E) lies approximately 10 km off the coast (the village of Candolim).
Due to logistic reasons (mainly the non-availability of a suitable vessel during
the turbulent monsoon season), the sampling has not been as regular as needed
for an optimal time series. However, during the crucial late SWM - early fall
intermonsoon (FI) period (August-November) the station has been visited at
least once a month between 1997 and 2004. The data have been pooled and av-
eraged for various depth intervals on a fortnightly basis for August-December
