Description The Arabian Sea has an excess evaporation over precipitation regime. The southeast Arabian Sea is, however, anomalous because it has ~2800–4800 mm rainfall during the southwest monsoon (SWM). Despite a high rainfall, the fluvial influence on supply of total suspended matter (TSM) and marine productivity is deemed insignificant and remains unevaluated. We evaluated the poorly resolved influence of fluvial influx on shelf processes. We documented low salinity, stratification, high productivity, and turbidity over the entire inner shelf (chlorophyll-a ~2.4 mg m sup(−3); PO sub(4) sup(3−) >2.5 mu M; NO sub(3) sup(−) 6.8–2.1 mu M; TSM 88–182 mg l sup(−1); salinity nearshore region 26; offshore region 33.8–34.6 practical salinity units). The deeper regions (>40 m), however, had greatly reduced TSM and nutrient levels (NO sub(3) sup(−) and PO sub(4) sup(−3)
