Saline Waters

It is widely recognised that, unless special steps are taken, analytical results from a group of laboratories engaged in a monitoring programme are likely to be of poor comparability. This in turn can prejudice the conclusions drawn from the results of monitoring. On the basis of previous studies, the problem is known to be particularly acute for measurements of trace metals in saline waters. Recognising the difficulty, the Marine Pollution Monitoring Management Group (MPMMG) and the Water Research centre (WRc) have organised a programme of Analytical Quality Control (AQC). This has the objective of ensuring that analytical results for filterable cadmium and mercury in saline waters, obtained by water industry and other relevant laboratories, are of adequate accuracy and comparability for their intended uses. WRc is to coordinate a series of tests, some involving distributions of standards and samples, which the participating laboratories undertake; this series of tests, the background to the approach and some of the results obtained to date are described here.

Most historical marine pollution monitoring has proven useless in a management context. A strategy for development of effective marine pollution monitoring programs is outlined. This strategy is based on the following steps: 1) systematic evaluation of the management information needs, 2) identification of the hypothetical impacts associated with those management concerns, and 3) investigation of the feasibility of monitoring those effects such that the existence, or absence, of a specified level of effects can be established in a statistically-valid manner. There are two fundamentally different types of monitoring program: site-specific and regional. These two types of program differ markedly in scope and approach when designed through application of this strategy. The strategy requires development of null hypotheses which address management concerns and which are amenable to scientific testing. In order for the program to be successful, the null hypotheses selected for inclusion in a marine pollution monitoring program must address levels of effect which are predefined to be environmentally significant. The definition of environmentally significant effect levels is a difficult process which must be primarily the responsibility of the managerial community.

Preliminary Phase

An integrated surveillance system for chronic and accidental marine pollution is proposed to improve decision making. This project, called ARCOBLEU, is based on organizing advanced communication and information tools and techniques in a multi-source / multi-user architecture. A Franco-Italian consortium associating private companies and public research institutes has already received the support of the EEC MAST program to carry out the preliminary phase of the system requirement, by using the high Tyrrhenean sea as a pilot zone. Future extension to the Western Mediterranean basin is already planned under the name of MED-ARCOBLEU.

Contamination Levels

The main objective of this study was to evaluate the contamination by mercury (Hg), methylmercury (Me-Hg), cadmium (Cd), selenium (Se), zinc (Zn), copper (Cu), iron (Fe) and manganese (Mn) in dolphins stranded on the French Mediterranean coast. The distributions of these contaminants in the organs of dolphins have also been studied. Overall, contamination levels varied according to the following sequence: liver > kidney > lung > muscle, except for cadmium (kidney > liver > lung > muscle). Size and sex of animals were also considered. Young dolphins were less impacted with trace elements than adults, except for copper. Among the studied parameters, the most important appeared to be the size of mammals. In addition, in the case of mercury and selenium, the sex of mammals seemed to be also relevant. The correlations between the concentrations of trace elements suggest the existence of detoxification processes. Since 1990s, using dolphins for tracing marine pollution, a slight reduction in the burden of the considered trace elements could be noted.

As the planet’s largest ecosystem, oceans stabilise climate, produce oxygen, store CO2 and host unfathomable biodiversity at a deep time-scale. In recent decades, scientific assessments have indicated that the oceans are seriously degraded to the detriment of most near-future societies. Human-induced impacts range from climate change, ocean acidification, loss of biodiversity, eutrophication and marine pollution to local degradation of marine and coastal environments. Such environmental violence takes form of both ‘spectacular’ events, like oil spills and ‘slow violence’, occurring gradually and out of sight. The purpose of this paper is to show four cases of coastal and marine forms of slow violence and to provide counter-accounts of how to reinvent our consumer imaginary at such locations, as well as to develop what is here referred to as ‘low-trophic theory,’ a situated ethical stance that attends to entanglements of consumption, food, violence, environmental adaptability and more-than-human care from the co-existential perspective of multispecies ethics. We combine field-philosophical case studies with insights from marine science, environmental art and cultural practices in the Baltic and North Sea region and feminist posthumanities. The paper shows that the oceanic imaginary is not a unified place, but rather, a set of forces, which requires renewed ethical approaches, conceptual inventiveness and practical creativity. Based on the case studies and examples presented, the authors conclude that the consideration of more-than-human ethical perspectives, provided by environmental arts and humanities is crucial for both research on nature and space, and for the flourishing of local multispecies communities. This paper thus inaugurates thinking and practice along the proposed here ethical stance of low-trophic theory, developed it along the methodological lines of feminist environmental posthumanities.
