Manganese and suspended matter in the Yaquina Estuary, Oregon

  title={Manganese and suspended matter in the Yaquina Estuary, Oregon},
  author={Richard J. Callaway and David T. Specht and George R. Ditsworth},
The longitudinal distribution of total suspended matter and total, dissolved, and particulate manganese in a small coastal plain estuary is described. The distribution of manganese is a consequence of estuarine circulation; a within-estuary maximum is inversely correlated with river flow, and is a function of residence time in the estuary, resuspension in the upper estuary, and desorption from particles introduced from within the estuary or from the river. The turbidity maximum is similarly… 
The behaviour of dissolved Mn, Ni and Zn in the Forth an industrialised, partially mixed estuary
Abstract The distributions of dissolved Mn, Ni and Zn concentrations in the Forth estuary are described, interpreted and discussed. The Forth estuary has a long flushing time and, in summer, is
Importance of seasonal variability and coastal processes on estuarine manganese and barium cycling in a Pacific Northwest estuary
Abstract Dissolved and particulate manganese (Mn) and barium (Ba) within the Tillamook Bay estuary are examined over seasonal cycles under a range of river discharge conditions from January to
Dissolved manganese in the columbia river estuary: production in the water column
Abstract A chemical sensor was deployed as part of a package of instruments to develop a highly resolved picture of dissolved Mn and related parameters in the Columbia River estuary. The vertical
Manganese and iron release from mangrove porewaters: a significant component of oceanic budgets?
Abstract Mangrove porewater can be highly enriched in dissolved manganese (Mn), iron (Fe), and other trace metals. As a result, porewater exchange may release dissolved metals to surface waters. This
Contamination of Uppanar River and coastal waters off Cuddalore, Southeast coast of India
The study is based on physicochemical parameters (pH, DO, and salinity) and dissolved trace elements (Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn, and Cd) of Uppanar River water (RW) and surface and bottom
Concentrations of dissolved and suspended particulate Cd, Cu, Mn, Ni, Pb and Zn in surface waters around the coasts of England and Wales and in adjacent seas
Trace metal concentrations in British coastal waters were determined during the summers of 1991 and 1992. The measured concentrations of Cd, Cu, Ni, Pb and Zn are in general agreement with those
Spatial and temporal distribution of metals in suspended particulate matter of the Kali estuary, India
Abstract Major (Al, Fe, Mn, Ti, Mg) and trace (Cu, Zn, Pb, Cr, Ni, Co, Zr, Rb, Sr, Ba, Li, Be, Sc, V, Ga, Nb, Mo, Sn, Sb, Cs, Hf, Ta, Bi, Th, U) elements and particulate organic carbon (POC)
Seasonal Variation in Some Metals of Inshore Waters of Malvan, Maharashtra
Metals were investigated at Tarkarli, Kolam and Aachara estuary of Malvan, Maharashtra under low tide situation in different seasons. Ni, Cu, Pb and Mn were observed nil during monsoon season, while
A baseline study of physico-chemical parameters and trace metals in waters of Ennore Creek, Chennai, India.
Chennai (Madras) is a metropolitan city with a high-density population of 4 million (as well as 1.5 millionfloating population) and is drained by the Adyar Riverin the south, Cooum River in the
Metal status of water in mangrove ecosystem of Maharashtra coast, India
Temporal and spatial distribution of dissolved and total elements (Cu, Cd, Fe, Mn, Ni, Zn, Cr, Pb and Hg) and physicochemical parameters of water courses in the vicinity of three mangrove sites along


Behaviour of manganese in the Rhine and Scheldt estuaries: II. Geochemical cycling
Measurements of dissolved and particulate suspended Mn concentrations throughout the Rhine and Scheldt estuaries are interpreted in terms of cycling processes of Mn. Dissolved Mn is removed in the
Manganese cycling in the Newport River estuary, North Carolina
Abstract Dissolved Mn was measured in the Newport River estuary, North Carolina, in October 1974, February 1975 and April 1975 by extraction on Chelex-100 resin and subsequent analysis by flameless
The dynamics of estuarine manganese cycling
Seasonal observations of dissolved managnese in the Tamar Estuary,south-west England have demonstrated pronounced temporal and spatial variability in the distribution of this component. Simultaneous
The dynamic balance of manganese transport and diagenesis in the Otago Harbour, New Zealand
Abstract The input and internal cycling of manganese in the Otago Harbour, a shallow marine embayment, have been studied. Freshwater transport of dissolved and particulate Mn was measured during
The sources of dissolved manganese to Calico Creek, North Carolina
Abstract A small tidal creek in North Carolina has, during the spring and summer months, dissolved Mn concentrations in excess of concentrations predicted by simple mixing with the nearby Newport
Distributions and behaviour of dissolved Cu, Zn and Mn in the Tamar estuary
Abstract Concentrations of dissolved Cu, Zn and Mn have been recorded together with salinity, suspended particulate load, dissolved oxygen and pH, in twenty-two transects of the Tamar Estuary carried
The behavior of iron, manganese and silicon in the Peconic River estuary, New York☆
Abstract The behavior of dissolved and particulate iron and manganese and dissolved silicon has been studied as a function of chlorinity in the Peconic River estuary, New York. This study sought to
Behaviour of manganese in the Rhine and Scheldt estuaries. I. Physico-chemical aspects
Abstract An equilibrium model of the behaviour of manganese during mixing of river- and seawater in estuaries is established on the basis of published thermodynamic data about manganese species in
