Species point records from 1988-89 NRA Orwell Estuary sublittoral survey

The main objective of this study was to assess the impact of the major discharge, Cliff Quay Sewage Treatment works on the benthic fauna of the Orwell Estuary. One Day Grab sample was taken at each of twenty eight sites. Sub samples of the sediment were taken for particle-size analysis and organic carbon content determination. The remainder of each sample was put through a 500 micron sieve and stored for later analysis. The results obtained indicated a gradual improvement of the subtidal fauna in a seaward direction. Four species assemblages were identified correlating with the distance down stream from the Orwell Bridge, the combined percentages of silt and clay and the percentage of organic carbon content. Sites in the upper estuary had low diversity, dominated by Tubificoides pseudogaster, Tubificoides swirencoides and Tharyx sp.. A faunistically impoverished area was observed around the Woolverstone Marina (sites 7-10), whereas an area of relatively high diversity was detected down stream of Collimer Point (sites 19-28).

Species point records from 1988-89 NRA Orwell Estuary littoral survey

The main objective of this survey was to assess the impact of the major discharge, Cliff Quay Sewage Treatment works on the intertidal fauna of the Orwell Estuary. All twenty five sites were located between Cliff Reach and Shotley Point. A sediment sample was collected at each site for particle-size analysis and organic carbon content determination. Data from sites 1, 4, and 24 are missing from the survey report. In a preliminary survey, the upper estuary had been described as faunistically impoverished, suffering from over-dominance of a few species, in particular Tharyx sp and the tubificids. Contrary to the preliminary survey, no major trends in intertidal species diversity were found along the length of the estuary. Species assemblages were found to be related to the percentage of clay, the percentage of silt and the mean particle size of the sediment. Very high levels of abundance were recorded in the upper estuary, the dominant species being Tubificoides pseudogaster.

Species point records from 1965-70 DAFS Scottish littoral sediment survey

The study of a number of sandy beaches covering a range of environmental conditions revealed faunistic variation which reflected the different species' tolerance of or preference for the conditions prevailing on particular beaches. Whenever a balanced situation in the environmental conditions existed, especially between shelter and exposure, a typical marine north-temperate water community characterised by the bivalve Tellina tenuis was present. This comunity included a basic faunistic complement consisting of polychaetes (both sessile and errant) on the mid and lower shore, and a few crustaceans on the upper shore. Severe exposure restricts diversity, eliminating sedentary forms, especially bivalve molluscs and, encouraging the numerical dominance of agile swimmers such as haustoriid amphipods and isopods. These species have a short life-span and the fauna is characterised by its flexibility. Extreme shelter favours the establishment of a predominantly sessile community of polychaetes and long-living bivalves.

Species point records from 1991 ICI north-east England sublittoral sediment survey

The Tees Estuary (north-east England) has been industrialised since the ninteenth century and used for the disposal of industrial and domestic waste. Its physical nature has been changed by canalisation and dredging. In 1970 a number of water quality objectives were established by the Northumbrian River Board and local industry, and during the 1970's water quality improved. Classification analysis identifies 3 faunal associations within the estuary. The seaward end of the estuary has a typical estuarine fauna, and the middle reaches are dominated by an abundant fauna tolerant of organic pollution. Species diversity and abundance increased between 1979 and 1985 with the penetration of marine fauna into the estuary and increase in abundance in the middle reaches.

Species point records from 1969 Gage Lochs Etive, Creran and Lochnell Bay sublittoral survey

The vertical distribution of the benthic fauna associated with soft sediments in sealochs was investigated by divers taking pairs of core samples at a series of depth levels along a transect from the shore out to a maximum depth of 25 m. Eight transects were worked, 5 in Loch Etive, 2 in Loch Creran and 1 in an adjacent area in Lochnell Bay outside the two lochs. The samples from each transect were objectively classified into hierarchical groupings by applying a clustering strategy to the values of an index of faunal similarity derived from the species abundances data. An attempt is made to relate the structures shown to physical differences measured along the transect in terms of depth, topography, sediment granulometry and exposure. In Loch Etive, the groupings were found to be best correlated with the pattern of intense vertical gradients in salinity and temperature. These are caused by the semi-permanent depression of surface salinity by terrestrial drainage. The faunal distributions showed best correlation with the degree of fluctuation of salinity, measured near the transect sites in a long-term hydrographic study, rather than with its mean value. This indicated that the range and speed of salinity fluctuations probably primarily control the observed pattern of vertical zonation of the typically estuarine and euryhaline marine species found in the samples. In Loch Creran and Lochnell Bay, the groupings may best be related to a complex of unstable conditions including wave exposure, sediment type and occasionally reduced surface salinity.

Species point records from 1973 University of Bristol Severn estuary littoral survey

The pattern of the infauna on particulate shores of the southern coasts of the Severn Estuary has been examined. Although mud predominates as the major beach substratum within the Estuary, sand beaches occur in both the lower and the upper reaches. Liquid mud is found at l.w. in the middle reaches. Suitability of substratum is shown to be the most important factor influencing animal distribution. 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. Several species were rare or absent on mud beaches close to the entrance of the River Avon and the possibility that sewage contamination is responsible for this is discussed. The methods of sampling differed slightly at different transect sites. Normally one quadrat of area 0.25m2 was taken at each station and sieved through a mesh of 0.5mm. When the substratum was very firm mud or clay with a surface coating of softer mud which was less than 10cm deep, this surface layer only was taken, since it was impossible to force the clay through the sieve. Such samples were supplemented with 10cm deep cores of area 0.01m2. No distinction was made in the reprint of which stations had which method of sampling on them so both methods have been recorded at each station.

Species point records from 1993 WWA Severn estuary industral discharge pipe littoral survey

Invertebrate collections were made at 32 sites within a 6 ha area of inter-tidal mud sediments around the effulent outfall from Ashton paper mill; additional samples were collected for physico-chemical analysis. Seventeen taxa were recorded and invertebrate density varied between 1,580 and 32000 per m. There was no evidence that the effulent caused an increase in the organic content of the sediments although there were local reductions in redox potential. Other physico-chemical characteristics of the sediments were relatively uniform and the effulent did not have any discernable effects on the macroinvertebrate fauna, the communities around the outfall being similar to that occurring more extensively in this area of the Severn Estuary.

Species point records from 1993 WWA River Usk industrial discharge pipe littoral survey

The only major industrial outfall in the Usk Estuary is from the British Steel Company Orb Works which discharges effulent including a variety of metals, oils and neutralised pickling liquor. Previous studies have indicated that bioaccumulation of some metals by the alga Fucus vesiculosus may be attributable to this effulent and so a study of the benthic fauna was undertaken at 14 sites within a distance of 1.3 Km during July 1984 to assess the biological effects of the effulent. In addition bioaccumulation of metals by the polycheate Nereis diversicolor was also investigated. Seventeen macroinvertebrate taxa were collected (range 3-11 per site), the most widespread species being Nereis diversicolor and Macoma balthica, although the former species occured at relatively low densities within 200 metres of the discharge possibly indicating a deleterious effect as a result of the effulent. Copper concentrations in tissues of Nereis diversicolor were higher than in the sediments and were related with distance from the outfall, although tissue and sediment concentrations were generally similar to other estuaries such as the Humber. It was concluded that the effulent does have a detrimental effect on the fauna locally, although specific toxic substances were not identified. It is reccommended that proposed benthic studies in estuaries are supplemented by more widespread bioaccumulation studies, screening of effulent toxicity (for example Microtox system) and measurement of simple growth parameters of transplanted fauna.

Species point records from 1982 WWA Cardiff sewerage outfalls survey

The benthic macroinvertebrate fauna and the physico-chemical properties of the sediments were described from 66 sites in the vicinities of the Rhymney Valley, Ystradyfodwg and Pontypridd (Y & P) and Cardiff East outfalls discharging to the Severn Estuary. Except in an area close to the Y & P outfall, where redox potential was relatively low (<100 mV at 4 cm depth), the discharges had no perceptible effect on local sediment characteristics. Carbon concentrations were similar (50 mg g-1) to those found generally in this area of the Severn Estuary. A total of 26 taxa were identified and total invertebrate density ranged from 110 to 46,000 m-2. Except for an area close to the Y & P outfall, there was no evidence that the effulent discharges affected the distribution of the benthic macroinvertebrate assemblages around the outfalls were similar to those found generally in this area of the Severn Estuary. Classification analysis suggested that shore height was the environmental feature most closely associated with the distribution of the fauna.

Species point records from 1975-78 University of Bristol Severn Estuary littoral rock survey

Zonation of algae and invertebrates was examined on rocky shores in the Severn estuary from 1975 to 1978. These shores were characterised by an absence of macro-algae from MLWS and below. Some littoral algae showed reductions in abundance during the study. In particular, Ascophyllum nodosum and Fucus serratus almost disappeared from the mid-shore at one site after 1976, and no significant recolonisation had occured by 1979. Animal species in general showed predictable and constant zonation patterns, but Littorina rudis, Patella vulgata and Eliminus modestus all exhibited decreased upper vertical limits in the upper reaches of the estuary. Three approaches were taken to interpret the zonation patterns of their changes. 1. Exposure to wave action was estimated. Decreasing exposure levels may account for the decline in upper vertical limits of species in the upper estuary. 2. A survey of silt, salinity and temperature was carried out over compelte tidal cycles. High silt concentrations may partially explain the absence of macro-algae below MHWS. 3. Preliminary experiments compared the effects of grazers in the estuary with those in fully marine conditions. These experiments point to some of the factors which are responsible for the lack of algal recolonisation on the shore from which the dominant fucoids disappeared after 1976, but the situation is complex and involves algal reproductive biology as well as grazer activity.
