Low Cost, Low Technology Field Monitoring Assessment, 2016 Edition (K542E) (eBook)

(Excludes any applicable taxes)

The publication provides practical information about low cost and low technology tools useful for monitoring of possible environmental impacts associated with disposal at sea of dredged material or inert, inorganic geological materials. The primary audiences are countries that are in the early stages of developing waste assessment and monitoring actions in concert with permit programmes for disposal of wastes and other matter at sea.

The objective of this document is to provide guidance on monitoring techniques for countries that are developing capabilities to assess environmental impacts of the disposal of wastes or other matter into marine waters, but at this point in time are limited in their scientific, technical, and economic abilities to carry out comprehensive and state-of-the-practice monitoring programmes.


Guidance is provided for use of low cost and low technology sampling and analysis monitoring techniques for two categories of wastes and other matter, dredged materials and inert, inorganic geological materials.


This guidance is based on Annex 2 to the London Protocol and has been developed by parties to the London Protocol and the London Convention, the two primary international treaties protecting the world’s oceans from pollution. These treaties are managed under the International Maritime Organization, a specialized agency of the United Nations. Waste Assessment Guidelines (WAG s) are available from the London Protocol and London Convention that provide robust procedures for assessment of wastes proposed to be dumped in the ocean; the WAG s include a section on monitoring of the environmental impacts at the disposal site and in the surrounding areas.

A​​s a specialized agency of the United Nations, IMO is the global standard-setting authority for the safety, security and environmental performance of international shipping. Its main role is to create a regulatory framework for the shipping industry that is fair and effective, universally adopted and universally implemented.  

In other words, its role is to create a level playing-field so that ship operators cannot address their financial issues by simply cutting corners and compromising on safety, security and environmental performance. This approach also encourages innovation and efficiency.

Shipping is a truly international industry, and it can only operate effectively if the regulations and standards are themselves agreed, adopted and implemented on an international basis. And IMO is the forum at which this process takes place.
