The Bengal Fan, the largest submarine fan in the world, spanning the whole Bay of Bengal resulted from the India-Asia collision event and subsequent Himalayan orogeny. It is a significant depositional feature formed by the major river systems: the Ganges and Brahmaputra. Previous studies revealed the occurrence of an extensive channel-levee system...

All landscapes, including estuarine islands, normally try to restore their geomorphic isostasy in all anthropogenic interventions on land dynamics. Munroe Island has been experiencing drastic environmental degradation, such as land subsidence, severe tidal/monsoon flooding, subsidence of build-ups and a drastic decay in agricultural productivity. T...

This study uses observed water level data to analyse the variability and causes of long-period oscillations entering the Ashtamudi estuary in order to understand Munroe Island inundation. Observations shows most significant spectral energies of 42-day, 20-day and 13-day exists inside the estuary with an amplitude of about ~10-20 cm in water level a...

Continuous collection of hydrodynamic data from the nearshore region by deploying marine instruments is challenging, mainly because of the huge cost and risk involved in keeping these sophisticated instruments in the highly dynamic nearshore region, since the area is often subjected to harsh environmental conditions. In such situations, adoption of...

The Arabian Sea is a semi-enclosed basin covering the western part of the northern Indian Ocean. Understanding this basin is of great importance for the developmental activities of its surrounding countries. Reliable information about the sea state, particularly in shelf sea regions, is essential for effective planning and execution of offshore ins...

A 38-year high-resolution wind climatology shows a consistent occurrence of hitherto unreported South Asian subtropical low-level jets (SASLLJs) over the 31°–35°N and 60°–62°E latitude–longitude region, occurring throughout the year are the northerly LLJs (NLLJs) and southerly LLJs (SLLJs). The NLLJ is persistent mostly during the monsoon season. T...

Persistent and periodic northerly low‐level jets have been identified in the South Asian mid‐latitudes and subtropics, which are modified by the presence of Makran mountain ranges adjacent to the central south coast of Pakistan, where they blow predominantly in the west‐northwest to northeast directions. These winds lead to the generation of a new...

This study examines the role of increased Indian Ocean warming and positive Indian Ocean Dipole (IOD) events on the surface chlorophyll concentration in the Eastern Arabian Sea (EAS) during the period 1998 to 2014. Remotely sensed surface chlorophyll concentration – during the month of October when IOD strength is maximum – at three selected areas...

The aim of the present research is to investigate the directional characteristics of waves along the southwestern Bay of Bengal based on the measured data during 2010 at 14 m water depth. Diurnal, monthly and annual variation of reflected waves is studied for waves within a frequency range of 0.03–0.125 Hz to eliminate the influence of local wave g...

Intrinsic modes of variability have a significant role in driving climatic oscillations in the ocean. In this paper, we investigate the influence of inter-annual variability, the Indian Ocean Dipole (IOD), on the wave climate of the eastern Arabian Sea (AS). Using measured, modeled and reanalysis wave data and reanalysis wind data, we show that the...

Intrinsic modes of variability have a significant role in driving the climatic oscillations in the oceanic processes. In this paper, we investigate the influence of an inter-annual mode of variability, the Indian Ocean Dipole (IOD), on the wave climate of the eastern Arabian Sea (AS).

The spatial and temporal variations of wave height in shelf seas around Indian mainland are examined based on the ERA-Interim dataset produced by the European Centre for Medium-Range Weather Forecasts. The study shows that during the summer monsoon, higher wave heights are observed in all locations except at the southern locations in the shelf seas...

The climate over the North Indian Ocean (NIO) is one of the most dynamic in the world due to seasonally reversing monsoon winds. In this study, we analyze the climate of the NIO and the variability of its surface waves using the European Centre for Medium Range Weather Forecast (ECMWF) global atmospheric re-analysis product (ERA-Interim) for the pe...

As a renewable energy, the assessment of wave power potential around a country is crucial. Knowledge of the temporal and spatial variations of wave energy is required for locating a wave power plant. This study investigates the variations in wave power at 19 locations covering the Indian shelf seas using the ERA-Interim dataset produced by the Euro...

The wave statistical parameters during Cyclone Phailin which crossed the northern Bay of Bengal are described based on the Directional Waverider buoy-measured wave data from 8 to 13 October 2013. On 12 October 2013, the cyclone passed within 70 km of the Waverider buoy location with a wind speed of 59.2 m s−1 (115 knots), and during this period, a...

Information on reflected surface gravity waves from the shoreline is required for understanding the coastal hydrodynamics. We have quantified the reflected swells (frequency band 0.045–0.12 Hz) from the west and east coast of India based on the spectral wave data derived from the directional waverider buoys. Reflection coefficient, ratio of the ref...

We studied the spatial and temporal variation of surface waves along the eastern Arabian Sea during 2011 and 2012. Measured directional wave data at two shallow water locations and re-analysis datasets (ERA-Interim) at 0.75° intervals at four locations were used for the study. The study region covers 270 km along the west coast of India and lies be...

The directional characteristics of shallow water waves are described based on measured data during 2011 at two locations spaced at 350 km along the eastern Arabian Sea. Study shows that, for high swells (significant wave height > 1 m) approaching almost parallel to the coast, the difference between mean and principal wave direction at spectral peak...
