Showing papers in "Estuarine and Coastal Marine Science in 1973"

TL;DR: In this paper, an analysis of surface sediments from eight stations and in clams (M. mercenaria) from three stations in Narrangansett Bay showed that both contain a very complex mixture of hydrocarbons which is present in crude oils and fuel oils.

TL;DR: In this paper, a model for oscillatory tidal flow over parallel topography is considered, with a view to determining associated time-mean currents, and it is found that the Coriolis force and bottom drag are each responsible for distinct mechanisms of mean-current generation.

TL;DR: In this article, the seasonal renewal of deep water in Saanich Inlet was investigated and the time for 37% renewal of the deep water was estimated to be about 12 days.

TL;DR: In this paper, the authors used a three-dimensional grid to check for possible effect due to a steam electrical generating station (s.e.s.) in the middle Patuxent Estuary in Maryland.

TL;DR: Dotilla fenestrata, an ocypodid crab which burrows intertidally on sandy substrates, was studied near Dar es Salaam on the East African coast.

TL;DR: In this article, the effects of suspended sediment particles and changes in salinity on the precipitation of iron in sea water are studied, and it is shown that both increasing salinity and the presence of suspended particles increase the rate and extent of iron precipitation.

TL;DR: The total biomass of fish remained remarkably constant throughout the year when compared to adjacent coastal environments, while the abundance of particular species varied substantially with season.

TL;DR: In this paper, salt marsh plots 10 m in diameter were fertilized once every two weeks with commercially available sewage sludge and nutrient losses measured in ebbing tidal water, and principal losses were in the form of ammonium and phosphate and were related principally to dosage applied and height of tide following application.

TL;DR: In this paper, the authors proposed a more general approach for the prediction of salinity distribution for the Thames estuary, and applied it to test cases in particular to predict salinity in the English Thames.

TL;DR: The pattern of the infauna on the southern coast of the Severn Estuary has been examined in this paper, showing that the number of infaunal species found in this survey did not increase markedly towards the mouth, in contrast to the pattern displayed by rocky shore animals.

TL;DR: Chaetoceros armatum has been observed to undergo a diel periodicity in buoyancy in the surf zone, becoming dispersed throughout the water column at night and rising to the surface again each morning.

TL;DR: The distribution of Himanthalia elongata has been surveyed along the north-east coast of England and it has been shown that a slight decrease in salinity decreases the percentage of germination and below a salinity equal to 50% sea water no germination occurs as mentioned in this paper.

TL;DR: In this article, the effects of Woods Hole, Massachusetts sewage outfall on the surrounding benthic community were examined, and in situ oxygen uptake measurements of the sediment were made before and after treatment with antibiotics and formalin.

TL;DR: In this article, seasonal variations in dissolved and particulate humic acids were studied for a one year period in an east coast estuary, and the general seasonal trend of both factions showed a sharp increase in concentrations in the spring followed by a decrease during the summer and winter months.

TL;DR: Branched chain acids appear to be the result of microbial activity and their high levels in the suspended organic matter, together with the fatty acid concentrations of the model studies using extracted marsh grass, indicate that micro-organisms are very important in the formation of the natural organic detritus.

TL;DR: Acid waste discharges did not appear to be responsible for the large variations in zooplankton biomass previously observed in the survey area since mortality of species due to short term exposure to high concentrations of waste appears small and little effect on adults or larval forms at great dilutions could be demonstrated.

TL;DR: In this paper, the authors found that the upper Narragansett Bay surficial sediments contain a complex mixture of hydrocarbons at over ten times the levels of the lower Bay.

TL;DR: The distribution of benthic animals was studied in shallow water in the south east corner of Liverpool Bay into which a new coastal sewage outfall will discharge as mentioned in this paper, where periodic samples were collected from 35 grab stations and at eight of these a beam trawl and epibenthic sledge were also used.

TL;DR: The replacement of species along the estuary is shown to relate to differences in their tolerance of various physical conditions, including temperature and salinity tolerances and substrate preference.

TL;DR: The results indicate that species adapted to a fluctuating estuarine environment are more influenced by the extra stresses of heavy metal pollution than marine forms for which environmental variables are relatively more stable.

TL;DR: The acid-iron wastes appeared to be a minor factor affecting the distribution and abundance of zooplankton species during the time of this investigation, and empirical measures of the variability of single species populations and community indices presented in the text may be useful guides for future surveys or monitoring studies.

TL;DR: In this article, a quantitative study was made of the invertebrate macrofauna and fish fauna of two shallow water ecosystems, one was in an inlet on a clean sand bottom and the other was on a muddy bottom near a discharge point for domestic effluent.

TL;DR: In this paper, a stoichiometric model was used to estimate reserve and oxidatively regenerated inorganic nitrogen and phosphorus fractions in the Baltic waters, showing that the organic phosphorus fraction is dominant in the photic layer whereas the organic nitrogen is dominant at all depths.

TL;DR: In this paper, chemical data (nutrients and some trace metals) for surface water obtained in December 1970 and March 1971 from Liverpool Bay shows that the runoff from river Mersey can be identified in the Bay.

TL;DR: In this paper, a one-year study of interstitial waters from surface sediments frozen immediately in the field showed that dissolved SiO2, NH4+ and PO4−3 were higher from August through November than during other months.

TL;DR: In this paper, an analysis of steady-state gravitational circulation in the near-surface zone of a fjord segment is presented, where conditions for a similarity analysis are satisfied.

TL;DR: In this article, the primary production and respiration of two marine ecosystems were studied by measuring changes in dissolved oxygen levels, and growth, respiration and turnover rates were discussed together with estimates of ecological efficiencies.

TL;DR: In this article, the concentration of dissolved and particulate mercury in the Bristol Channel and Severn Estuary was investigated and the distribution of both forms of the element were consistent with the water circulation pattern.

TL;DR: Swanpool at Falmouth, Cornwall has a mean depth of 1.6 m and contains about 80 000 m3 of brackish water as discussed by the authors, and it is estimated that in one year 20 to 30 times this volume of fresh water and about 2 pool-volumes of sea water enter the pool, which is liable to become unusually dilute at these times.
