  • Marine and coastal environment

    Although not always immediately apparent, our wellbeing as humans is affected by the environmental state of our seas, because many aspects of our lives benefit from the goods and services provided by well-functioning marine and coastal ecosystems. These ecosystem services offer a multitude of opportunities to provide an income for people for instance through production of fish and shellfish for ...

  • Marine Waste Management

    The Reasons of Marine Waste Management New rules from IMO (International Maritime Organization), adopted in July 2011, imply substantial changes for all ship or rig types as early as January 2013. By applying waste management, the ship or rig owner or operator takes control of waste handling with the aim of achieving some or all of the following objectives: 1) To fulfill ...

  • Environmental assessment of marine sediments off Poompuhar, Southeast Coast of India

    The environmental conditions Off Poompuhar was inferred with the aid of 38 sediment samples collected off Bay of Bengal north of Nagappattinam. Sediments were analysed to understand the geochemistry (textural analysis, TOC, CaCO 3 , major and trace elements) along the coastal tracts and their pollution rate using various geochemical indices. Metals like Cu, Cr and Zr shows enrichment more than ...

  • Towards a harmonised approach for environmental assessment of human activities in the marine environment

    With a foreseen increase in maritime activities, and driven by new policies and conventions aiming at sustainable management of the marine ecosystem, spatial management at sea is of growing importance. Spatial management should ensure that the collective pressures caused by anthropogenic activities on the marine ecosystem are kept within acceptable levels. A multitude of approaches to ...

  • Marine Snow Storms: Assessing the environmental risks of ocean fertilization

    The threats posed by climate change to the global environment have fostered heightened scientific and commercial interest in marine geo-engineering schemes designed to boost the capacity of the oceans to absorb atmospheric carbon dioxide. This is the primary goal of a process known as ocean fertilization, which seeks to increase the production of organic material in the surface ocean in order to ...

  • Phycotoxins in the marine environment: control of marine organisms for contamination with algal toxins

    On a global scale, the frequency and intensity of toxic algal blooms appear to be on the rise. There is also evidence of geographic spreading of toxic strains. Therefore, it is necessary to establish methods for the evaluation of possible hazards caused by the enrichment of algal toxins in the marine food chain. Different clinical types of algae-related poisoning have attracted scientific ...

  • Marine Industry experience with Aalborg Industries

    Port Authorities and Governing Bodies state that a ship cannot emit smoke of >20% opacity for more than 3 minutes when in port. The IMO set similar limits for on-board incinerators. The DSL-220 Opacity Monitor has been used successfully to measure smoke emissions from diesel engines, incinerators and boilers on board ship ensuring that environmental concerns are ...

  • The Ecosystem Approach To Marine Planning and Management

    Keywords: ecosystem management, marine spatial planning, Marine and Coastal Access Act 2009, marine protected areas (MPAs) Provisions for marine planning form a key component of the Marine and Coastal Access Act 2009 and the planning process has already commenced in some parts of the country. A book on The Ecosystem Approach to Marine Planning and Management is therefore timely. The ...


  • The MAGnificent Seven - Gunning for Marine Waste

    Waste Management World focused this article on Terragon Environmental Technologie's product, MAGS (Micro Auto Gasification System) and the solution it provides to the maritime sector.  MAGS transforms solid waste and sludges into energy which can be intergrated at the site where waste is generated.  New regulations from MARPOL Annex V came into effect on January 1, 2013 - virtually ...

  • Use of marine outfalls in wastewater disposal

    Global experience has shown that disposing of properly treated domestic wastewater through effective ocean outfalls is an economical and reliable strategy for wastewater disposal with minimal environmental impact. Better construction techniques, such as tunnelling, coupled with improved materials mean that the technology of marine wastewater disposal has advanced rapidly in recent years. ...

  • 10 messages for 2010 — Marine ecosystems

    Key messages Marine ecosystems provide key services both globally and locally, which are essential for maintaining life on our planet. However, marine biodiversity faces an unprecedented range of pressures. In recent years climate change has caused changes in species distribution and presents new challenges for marine biodiversity as oceans become more acidic. Most of the ...

  • Opinion: What is Marine Spatial Planning

    A SYSTEM OF INTEGRATED MARINE MANAGEMENT FOR UK WATERS The United Kingdom marine area is far greater than that of its landmass.1 The coastal areas and seas have provided convenient food, transport and waste disposal for centuries, as well as contributing to man's identity and sense of well-being. In recent years, biodiversity and the potential of biotechnologies from the oceans have ...


  • Is marine energy about to go mainstream?

    Why the costs of wave and tidal power could soon plummet - viewpoint from Dr Stephen Wyatt, Head of Technology Acceleration, Carbon Trust As the marine industry gathers in London for its annual get together one thing is clear; the sector is growing up fast.  So fast that it looks like it will soon be defying its critics and getting its feet seriously wet after many years of ...

  • Marine litter – a growing threat worldwide

    Increasing amounts of litter are ending up in the world’s oceans and harming the health of ecosystems, killing animals when they become trapped or swallow the litter. Human health is also at risk, as plastics may break down into smaller pieces that may subsequently end up in our food. These are just a few of the problems emerging from the waste collecting in our seas. There are now ...

  • Choice of biotests and bioindicators for evaluation of the quality of the marine environment

    Approaches to the analysis of marine environmental conditions using the embryos, larvae and juveniles of marine invertebrates are discussed. A general approach to the choice of biotests and bioindicators is described.Keywords: bioindicator, biotest, cadmium, chiton, copper, detergent, marine (sea) pollution, sea urchin, ...

  • A New Microbial Contact Assay for Marine Sediments

    The number of microbiological contact tests for marine sediments is low, although microorganisms enable a rapid screening and monitoring of sediment quality and a high resolution of hazard assessment. As no single biotest can provide reliable answers concerning the potential hazard of environmental samples, a combination of bioassays needs to be applied to serve this purpose. In order to cover ...


  • Bio-fouling control on marine vessels with ozone

    A recent pilot study on how to control accumulation of marine organisms on heat exchangers of marine vessels show that applying ozone is both effective and sustainable. Large economic impact Marine bio-fouling, or accumulation of marine organisms on heat-exchangers for cooling systems, is a challenge in the maritime sector and has both an economic and environmental impact. Worldwide ...

  • Hazardous substances in Europe`s fresh and marine waters

    Chemical substances are an essential part of our daily lives. They are used in health and consumer products, in food production and in a growing range of environmental technologies, to name but a few examples. They can be natural substances, they can be formed as the unintended by-product of natural and human-induced processes, or they can be synthesised specifically for use in industrial ...

  • Bioavailability of purified subcellular metals to a marine fish

    In this study, we took advantages of the supply of naturally contaminated oysters and investigated how the subcellular metal distribution and the metal burden in prey affected the transfer of metals to a marine fish, the grunt Terapon jarbua. The oysters Crassostrea hongkongensis with different contaminated histories were collected and separated into three subcellular fractions (metal‐rich ...
