| Sediments from the shell-fish culture areas in the Lagoon of Thau are mainly constituted of sand and mud elements ; at a depth of about 80 cm to 1 meter in the sediment, much coarser elements are found. These sediments are more clayey in the N-E corners of each area and in a general way, richer in organic matter than the other areas of the lagoon, with very negative oxido-reduction potentials. Ammonia and phosphate amounts in intersticial waters are very high. A gradient of concentration from the bottom towards the surface of the sediment is observed, thus inducing diffusing flows in the water column. |

| A new observational record of upper-ocean currents at 15 degrees N on the western coast of India is dominated by intraseasonal (55 - 110 day) variations of alongshore currents, whereas sea level at the same location has a clear seasonal signal. These observations can be interpreted within the framework of linear wave theory. At 15 degrees N, the minimum period for planetary waves is similar to 90 day, meaning that intraseasonal energy is largely trapped at the coast in the form of poleward-propagating Kelvin waves, while lower-frequency signals associated with the annual cycle can radiate offshore as planetary waves. This dynamical difference results in a steeper offshore slope of sea level at intraseasonal timescale, and thus stronger geostrophic... |

| Recent observational studies provided preliminary insights on the interannual variability of Bay of Bengal (BoB) Sea Surface Salinity (SSS), but are limited by the poor data coverage. Here, we describe the BoB interannual SSS variability and its driving processes from a regional eddy-permitting ocean general circulation model forced by interannually varying air-sea fluxes and altimeter-derived discharges of major rivers over the past two decades. Simulated interannual SSS variations compare favorably with both in situ and satellite data and are largest in boreal fall in three regions: the northern BoB, the coastal region off east India, and the Andaman Sea. In the northern BoB, these variations are independent from those in other regions and mostly driven... |
