Intensive biological survey of the Glaze Brook catchment May 1981

This is the Intensive biological survey of the Glaze Brook catchment May 1981 report produced by the North West Water Authority in 1981. The aim of this report is to identify those pollution problems not identified during the routine biological water quality surveys, and to check the suitability of the routine biological sampling point. This report looks at an intensive biological water quality survey of the Glaze Brook catchment which was carried out by Biol. (S) on 13th-15th May, 1981. Kick samples of invertebrates were taken at 5 sites and all invertebrates were identified and counted in the field. The most significant water quality observations in the report were from: Borsdane brook, Pennington brook, Glaze brook, Amberswood brook, Cunningham brook, Old Mill brook, Shakerley brook, Astley brook and Shaw brook.

Intensive biological survey of the Glaze Brook catchment. Supplementary report on the water quality as indicated by macrophytes. August 1981

This is the Intensive biological survey of the Glaze Brook catchment: Supplementary report on the water quality as indicated by macrophytes produced by the North West Water Authority in 1981. This report describes the results of the macrophyte survey including data on their distribution and the prevailing water quality (nutrient status and toxic metal contamination) It supplements the initial report,TS-BS-81-3, which described the macroinvertebrate survey. The aim of this project is to describe the distribution of macrophytes within the river, paying attention to areas where weed growth may directly affect water quality or amenity usage, and describe the distribution of toxic metals. In the survey 16 sites of 500 m lengths of river were analysed, noting the relative abundance and percentage cover of the macrophytes present, plant score and Community Description Class (C.D.C.) were computed.

Kent estuary survey 18th August 1981

This is the Kent estuary survey 18th July 1981 produced by the North West Water Authority in 1981. The report focuses on a tidal cycle survey carried out on the Kent estuary on the 18th August, 1981. The chemical water quality at Arnside Pier and at New Barns was, on the whole, acceptable. However, samples taken downstream of the outfall at low water for total coliforms and E. coli were all above the EEC mandatory level whilst those for faecal streptococci were all above the guideline value. This document shows chemical and bacteriological data analysed at Kent estuary such chloride, dissolved oxygen, BOD, ammonia, nitrate, phosphate, total coliforms, E. coli and Faecal streptococci.

"Congregar, Congraçar e Unir: a atuação da Associação das Torcidas Organizadas do Rio de Janeiro (1981-1989)"

O presente trabalho busca compreender a atuação das Torcidas Organizadas e, torantes especificamente, da Associação das Torcidas Organizadas do Rio de Janeiro, no contexto da anistia política vivenciada no Brasil. Esse também é um período onde se nota o esgotamento do Milagre econômico, com enorme inflação, que acarretou diretamente no aumento do custo de vida e, para os torcedores, na majoração do preço dos ingressos para os jogos de futebol. A alternativa encontrada é uma série de boicotes e greves das torcidas no afã de reduzir o valor das entradas, contando com ampla cobertura da mídia, especializada, Jornal dos Sports, Revista Placar, ou a mais geral, Jornal do Brasil. Nosso objetivo é compreender as diversas iniciativas tomadas pela ASTORJ para alcançar suas vitórias, o discurso presente em suas lideranças, e a maneira como foi construída essa relação dialética entre torcidas e órgãos da imprensa e, para tal, analisaremos reportagens de jornais, revistas e de colunas como A Voz da Galera, presente no Jornal dos Sports, que se somam a entrevistas realizadas por nós junto a figuraschave da Associação das Torcidas Organizadas do Rio de Janeiro.

A geo-referenced benthic habitat survey in support of natural resource management: Port Graham Bay, Alaska

The impact of recent changes in climate on the arctic environment and its ecosystems appear to have a dramatic affect on natural populations (National Research Council Committee on the Bering Sea Ecosystem 1996) and pose a serious threat to the continuity of indigenous arctic cultures that are dependent on natural resources for subsistence (Peterson D. L., Johnson 1995). In the northeast Pacific, winter storms have intensified and shifted southward causing fundamental changes in sea surface temperature patterns (Beamish 1993, Francis et al. 1998). Since the mid 1970’s surface waters of the central basin of the Gulf of Alaska (GOA) have warmed and freshened with a consequent increase in stratification and reduced winter entrainment of nutrients (Stabeno et al. 2004). Such physical changes in the structure of the ocean can rapidly affect lower trophic levels and indirectly affect fish and marine mammal populations through impacts on their prey (Benson and Trites 2002). Alaskan natives expect continued and perhaps accelerating changes in resources due to global warming (DFO 2006).and want to develop strategies to cope with their changing environment.

Movement of American lobster (Homarus americanus) in the southwestern Gulf of St. Lawrence

A total of 42,445 American lobsters (Homarus americanus) were tagged in thirty-one sites throughout the southwestern Gulf of St. Lawrence between 1980 and 1997. Results from the recapture of 8503 tagged lobsters showed small distances traveled between the release and the recapture position for animals ranging in size from 51 to 152 mm carapace length. The average distance traveled ranged from 2 km in parts of Baie des Chaleurs and western Cape Breton to 19 km in central Northumberland Strait. Lobsters moved generally along the shore (93% of the dispersion was in areas between the shore and the 20-m bathymetric contour). As a result, lobsters traveled longer distances in sites characterized by a gradually sloping bottom where the distance between the shore and the 20-m contour line was extensive in contrast to areas characterized by rapidly changing depths and by a relatively small amount of habitat shallower than 20 m. In the majority of sites (14 of 19) there was no significant difference between males and females in the average distance they traveled. In four of the five sites females moved farther than males. In general, the average distance traveled by berried females was shorter than that traveled by males or nonberried females. No relationship was observed between the distance traveled and the size of the animal. There was no strong evidence of a relationship between the average distance traveled and the number of days at liberty. In general, lobsters in the southwestern Gulf of St. Lawrence traveled short distances and dispersion was restricted to the nearshore habitat. Further, the distance traveled was not correlated to size, sex, or years at large. These findings show that there is little interaction between American lobsters from different fishing areas at the benthic level and that American lobster movements should have minimal consequences for management of the species in the southwestern Gulf of St. Lawrence.

Relatório do cruzeiro realizado no Banco de Sofala pelo navio Pantikapey em Julho-Agosto de [1981]: peixes demersais

Thanks to an agreement between the Institute of Fisheries Research of Mozambique and the Soviet part Azcherniro and Ingribpomrazvedka, surveys in the waters of Mozambique were conducted from June to August 1981 on the ship Pantikapei. The survey made along the Sofala Bank and Boa Paz (16°00-21°00'S) was at a depths of 11 and 90 meters. Demersal and pelagic fisheries experiments were conducted using acoustic devices. This paper described the results obtained on demersal fishery resources.
