  • response of bacterial community structure to seasonal fluctuation and anthropogenic pollution on Coastal Water of alang sosiya ship breaking yard bhavnagar india
    Bioresource Technology, 2014
    Co-Authors: Vilas Patel, Hitendra Munot, Yogesh S Shouche, Datta Madamwar
    Abstract:

    Bacterial community structure was analyzed from Coastal Water of Alang-Sosiya ship breaking yard (ASSBY), world's largest ship breaking yard, near Bhavnagar, using 16S rRNA gene sequencing (cultured dependent and culture independent). In clone libraries, total 2324 clones were retrieved from seven samples (Coastal Water of ASSBY for three seasons along with one pristine Coastal Water) which were grouped in 525 operational taxonomic units. Proteobacteria was found to be dominant in all samples. In pristine samples, Gammaproteobacteria was found to be dominant, whereas in polluted samples dominancy of Gammaproteobacteria has shifted to Betaproteobacteria and Epsilonproteobacteria. Richness and diversity indices also indicated that bacterial community in pristine sample was the most diverse followed by summer, monsoon and winter samples. To the best of knowledge, this is the first study describing bacterial community structure from Coastal Water of ASSBY, and it suggests that seasonal fluctuation and anthropogenic pollutions alters the bacterial community structure.

  • A baseline study of tropical Coastal Water quality in Port Dickson, Strait of Malacca, Malaysia.
    Marine pollution bulletin, 2012
    Co-Authors: Sarva Mangala Praveena, Ahmad Zaharin Aris
    Abstract:

    Tidal variation in tropical Coastal Water plays an important role on physicochemical characteristics and nutrients concentration. Baseline measurements were made for nutrients concentration and physicochemical properties of Coastal Water, Port Dickson, Malaysia. pH, temperature, oxidation reduction potential, salinity and electrical conductivity have high values at high tides. Principal Components Analysis (PCA) was used to understand spatial variation of nutrients and physicochemical pattern of Port Dickson Coastal Water at high and low tide. Four principal components of PCA were extracted at low and high tides. Positively loaded nutrients with negative loadings of DO, pH and ORP in PCA outputs indicated nutrients contribution related with pollution sources. This study output will be a baseline frame for future studies in Port Dickson involving Water and sediment samples. Water and sediment samples of future monitoring studies in Port Dickson Coastal Water will help in understanding of Coastal Water chemistry and pollution sources.

  • Capturing Coastal Water clarity variability with Landsat 8.
    Marine pollution bulletin, 2019
    Co-Authors: Kelly Luis, Jennie E. Rheuban, Maria T. Kavanaugh, David M. Glover, Jianwei Wei, Zhongping Lee, Scott C. Doney
    Abstract:

    Coastal Water clarity varies at high temporal and spatial scales due to weather, climate, and human activity along coastlines. Systematic observations are crucial to assessing the impact of Water clarity change on aquatic habitats. In this study, Secchi disk depths (ZSD) from Boston Harbor, Buzzards Bay, Cape Cod Bay, and Narragansett Bay Water quality monitoring organizations were compiled to validate ZSD derived from Landsat 8 (L8) imagery, and to generate high spatial resolution ZSD maps. From 58 L8 images, acceptable agreement was found between in situ and L8 ZSD in Buzzards Bay (N = 42, RMSE = 0.96 m, MAPD = 28%), Cape Cod Bay (N = 11, RMSE = 0.62 m, MAPD = 10%), and Narragansett Bay (N = 8, RMSE = 0.59 m, MAPD = 26%). This work demonstrates the value of merging in situ ZSD with high spatial resolution remote sensing estimates for improved Coastal Water quality monitoring.

  • Remote Sensing Studies of an Upwelling Jet in Guangdong Coastal Water
    IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
    Co-Authors: Jiayi Pan
    Abstract:

    Summer upwelling is one of the most significant dynamic phenomena in the Guangdong Coastal Water, which transports bottom nutrients into the surface layer, facilities a high level of primary production in the offshore Water, and plays an important role in the Coastal ecosystem. In this study, we present detailed observations of an upwelling event that occurred in the Guangdong Coastal Water during July 14–16, 2003 using satellite multisensor data including the moderate resolution imaging spectroradiometer (MODIS) sea surface temperature (SST), QuikSCAT winds. The successive MODIS SST images reveal that the upwelled Water in the surface layer is in a jet-like wedge shape. A quantitative method is developed to estimate the upwelling vertical and horizontal velocities of the upwelled Water from the MODIS successive SST images, which are in good agreement with the observations. Based on the coastline geometry in the area, we derive analytical solutions to the upwelling system, which explain well the dynamic of the upwelling jet by comparison of the analytical solutions with the cross-shore expansion velocities of the upwelled Water.
