This book was released on 1999 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The year-long mooring records in the Arabian Sea (15 deg 30'N/61 deg 30E) show clearly the semi-annual biological response to the northeast and southwest monsoons. Each monsoon causes the mixed layer to deepen, but for the northeast monsoon, convective processes dominate, while during the southwest monsoon, the mixed layer deepens via wind-induced mixing. During both mixing periods, chlorophyll declines, and then increases as the water column stratifies. The annual cycle of chlorophyll variability at the mooring site (the climatological center of the Findlater Jet) generally follows the mixed layer depth. Strong diel variability in phytoplankton and particle variables were observed, and coherence analysis indicated that these were modulated more by water column processes (e.g., changes in the mixed layer depth) than by solar variability. We have demonstrated the utility of moored sensor systems in an unforgiving environment. The high-resolution data are extremely useful to those trying to understand the drivers for seasonal variability in productivity. The seasonal variability in productivity is crucial to interpret the export of carbon from the surface ocean to depth. The results will fuel consideration of the importance of diel processes in determining the activities of plankton.

Available in PDF, EPUB and Kindle. Book excerpt: A surface mooring was deployed in the Arabian Sea for one year. Subsequent analyses provided quantitative descriptions of the upper ocean response to the surface forcing, including heat budgets and identification of the relative roles of various physical processes. One- and three-dimensional models were used to further examine the dynamics of the response at the site of the moored array and to extend the study to the entire Arabian Sea. The fieldwork produced the first long time series of high quality surface meteorology and air-sea fluxes from the Arabian Sea. Observations of the strong cooling heat flux associated with offshore transport gave new insight into the dynamic mechanisms connecting coastal upwelling and upper ocean cooling. New understanding of the physics of the upper ocean in the Arabian Sea was developed, including the impact of the' diurnal cycle and of high-frequency wind forcing on the vertical mixing and on larger-scale circulation changes. Comparison of mixed layer model performance suggests some simple improvements in the parameterizations could be made in lieu of resolution of the diurnal cycle.

Book excerpt: This grant provided support for the collection, analysis and publication of results from the Arabian Sea Accelerated Research Initiative. The Arabian Sea is a unique setting for observations of the upper ocean because of the strength and directional steadiness of the monsoonal forcing. As part of the Arabian Sea ARI, we deployed two surface moorings of a five-mooring array to study the ocean's response to the monsoon. Each of our buoys was equipped with a meteorological package for estimating air-sea fluxes of heat and momentum, and subsurface instrumentation for measuring temperature and horizontal velocity. A variety of projects, discussed below, was brought to completion. The ultimate goal of my research is a complete characterization of the upper ocean 5 response to atmospheric forcing. The forcing takes place through surface fluxes of heat, fresh water, and momentum. The response may be local and direct, or may be modified by advection and wave propagation. The Arabian Sea was an attractive region for an air-sea interaction experiment because of the strength and steadiness of the monsoons. The wind-stress spectrum was more energetic at low frequencies in the Arabian Sea than in mid-latitude locations where the forcing is dominated by storms. The Arabian Sea ARI thus provided an interesting contrast to previous experiments done at higher latitudes such as LOTUS, FASINEX, and Ocean Storms. The ONR-funded surface moored array in the Arabian Sea consisted of a heavily instrumented central mooring (R. Weller, Woods Hole Oceanographic Institution), two profiling current meters (C. Eriksen, University of Washington), and two lightweight surface moorings (D. Rudnick, Scripps Institution of Oceanography). The array was centered at 15 deg 30'N, 61 deg 30'E, and the moorings were separated by 50 km to resolve mesoscale oceanic features. The site was chosen to be near the climatological maximum wind in July.

This book was released on 2013-05-09 with total page 1037 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 185. Indian Ocean Biogeochemical Processes and Ecological Variability provides a synthesis of current knowledge on Indian Ocean biogeochemistry and ecology and an introduction to new concepts and topical paradigm challenges. It also reports on the development of more extensive/frequent observational capacity being deployed in the Indian Ocean. This represents the first collection of syntheses that emphasize a basin-wide perspective, and the contributing authors include some of the most esteemed oceanographers and Indian Ocean experts in the world. The volume is derived from invited plenary talks that were presented at the initial Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER) workshop held at the National Institute of Oceanography (NIO) in Goa, India, in October 2006. The volume discusses The overlying physical processes set by monsoonal forcing and how these control biological production and variability Nutrient cycling and limitation Pelagic carbon cycling and air-sea exchange Benthic biogeochemistry and ecology The impact of climate and human activities on biogeochemistry and ecosystems. The readership for this book will consist of academic and governmental researchers interested in exploring how oceanographic, atmospheric, and hydrological processes combine to establish the environmental setting that supports and drives the pelagic system and which are especially relevant to understanding the complex biogeochemical and ecological interactions in the Indian Ocean.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of the upper ocean in the strong seasonally forced Arabian sea, as observed by a mooring deployed from 1994 to 1995, is investigated using the Naval Research Laboratory Layered Ocean Model (NLOM). Model simulations were sensitive to the choice of surface wind products used for forcing, and results are reported for simulations forced by monthly mean climatologies and 12-hourly 1994-95 wind products from two operational atmospheric forecast models, the European Centre for Medium-Range Weather Forecast (ECMWF) model and the Navy Operational Global Atmospheric Prediction System (NOGAPS) model of the Fleet Numerical Meteorology and Oceanography Center (FNMOC). The NLOM yields the best prediction of sea surface temperature (SST) and mixed layer depth (MLD) when using FNMOC forcing. Surface cooling is found to be responsible for the seasonal SST minimum during the northeast (NE) monsoon. Heat advection is found to be important for supporting the surface cooling during the second half of the NE monsoon. Strong entrainment and appreciable advective cooling are responsible for the SST minimum of the southwest (5W) monsoon. The NLOM wind experiments strongly suggest that thermal convection may be important in the central Arabian Sea during the winter months.
