sediment

  • Vivianite authigenesis in the surface sediments of the more isolated part of the estuary ultimately ceased, likely due to continued refreshening and an associated decline in productivity and P supply to the sediment. (springer.com)

Habitats

  • Tidal marshes , mudflats, and other significant habitats in and along the estuary support a great diversity of life. (ny.gov)

permanently open

  • The Sundays Estuary is permanently open to the sea and experiences regular freshwater inflow in the form of agricultural return flows with large supplies of nutrients. (scielo.org.za)

sedimentary

  • British Library EThOS: Radionuclide distribution in relation to sedimentary processes in the Esk estuary, UK. (bl.uk)

Waters

  • We demonstrate that bottom waters in the Ã…ngermanälven estuary became anoxic upon the intrusion of seawater in the early Holocene, like in the central Bothnian Sea. (springer.com)

intrusion

  • Salt-water intrusion in the Fraser River estuary was modeled numerically and compared with a field measurement program. (asce.org)

processes

  • While many of the existing books in estuarine science are comprised of edited volumes, typically focused on highly specific topics in estuaries, Biogeochemistry of Estuaries provides, for the first time, a unique foundation in the areas of geomorphology, geochemistry, biochemistry, aqueous chemistry, and ecology, while making strong linkages (trhoughout the text) to ecosystem-based processes in estuarine sciences. (oup.com)
  • Whether used by initiates to these complex systems or as a reminder of forgotten linkages, there is something in this text for anyone interested in the myraid of important processes in estuaries and their study. (oup.com)

diversity

  • The aim of this study was to conduct an investigation into the bacterial diversity in the freshwater-deprived Kariega Estuary, situated along the Eastern Cape coastline, using ribosomal RNA gene sequences obtained by pyrosequencing. (scielo.org.za)
  • Shifts in the microbial diversity were correlated to selected physico-chemical variables along the length of the estuary. (scielo.org.za)
  • More than 27 000 sequences were obtained and rarefaction analyses confirmed a comprehensive appraisal of the microbial diversity present in the Kariega Estuary. (scielo.org.za)
  • We conclude that pyrosequencing provides a versatile and efficient tool for assessing the microbial diversity in the Kariega Estuary and propose that this technology may provide valuable information on the ecosystem functioning and health of aquatic ecosystems. (scielo.org.za)

species

  • With projects that help manage and restore key species like striped bass and bald eagles, Estuary Grants have allowed counties, towns and villages in the Hudson River Valley to take ownership of their resources and define the future of their communities while contributing to the overall health and beauty of the region. (ny.gov)
  • The estuary was then sampled over 5 consecutive weeks from March to April 2009 to identify environmental factors that support different microalgal bloom species. (scielo.org.za)

upper

  • Phytoplankton blooms were found during Weeks 1, 4 and 5 from the middle to the upper reaches of the estuary. (scielo.org.za)

management

  • Created in 1987 through the Hudson River Estuary Management Act, the program focuses on the tidal Hudson and adjacent watershed from the federal dam at Troy to the Verrazano Narrows in New York City ( see map of Hudson River Estuary Program Boundary (PDF, 489 KB) . (ny.gov)
  • Built on sound science and principles of ecosystem-based management, the program is steered by the Hudson River Estuary Management Advisory Committee , which includes representatives of the commercial fishing industry, recreational anglers, utility companies, local government, educators, researchers, conservationists and other river users helps engage many representatives of the public in working together toward common goals. (ny.gov)

groups

  • In partnership with DEC's Hudson River Estuary Program, citizen groups and government agencies are making progess in restoring and protecting this great river for generations to come. (ny.gov)
  • This study is the first to show successive chlorophyll a blooms consisting of different phytoplankton groups in an estuary, an indication of the eutrophic state of the system. (scielo.org.za)

marine

  • Biogeochemistry of Estuaries will be welcomed by estuarine/marine scientists, ecologists, biogeochemists, and environmentalists around the world. (oup.com)

Program

  • What is the Hudson River Estuary Program? (ny.gov)
  • The Hudson River Estuary Program helps people enjoy, protect, and revitalize the Hudson River and its valley. (ny.gov)
  • The Hudson River Estuary Program collaborates with many partners including nonprofit organizations, academic and scientific institutions, businesses, local governments, state and federal agencies, and interested citizens. (ny.gov)
  • Available resources from the Estuary Program include educational materials, presentations, trainings, maps, planning guidance and links to further information. (ny.gov)

present

  • It was shown that diatoms occurred in blooms during warm, calm conditions whereas wind-mixing and reduced temperature, as a result of a cold front during 17 to 19 March 2009, promoted the dominance of flagellates throughout the estuary although they were present at all times. (scielo.org.za)

world

  • further downstream, a drastic decrease of these metals is observed and in the mid-estuary heavy metals concentrations agree with world average values found in not significantly polluted systems. (schweizerbart.de)

found

  • Details of these and other achievements can be found in our Hudson River Estuary Progress Reports . (ny.gov)

work

  • This article presents a synthesis of sedimentological and geochemical work carried out on the Gironde estuary until 1978. (schweizerbart.de)
