Navy efforts to protect whales have limited effect

Naval efforts to protect endangered whales by gradually increasing the noise levels of soner have limited benefit, researchers at the University of St Andrews have found.  The process of slowly raising the noise level of sonar, known as 'ramp up' was adopted by several European navies, and geophysical explorers who use airguns to search for oil and gas reserves, as a method to reduce the harmful impact of very loud sounds produced by humans in the sea.

The International Quiet Ocean Experiment (IQOE)

The IQOE have now launched their re-designed website (www.iqoe.org).  The site features all the content as before, with more modern graphics and better integration of the Aquatic Acoustic Library and the database of observing systems.

Lloyd's Register announces new underwater noise notation

Lloyd's Register has released a new underwater noise notation and ShipRight procedure on underwater radiated noise with the intention of helping shipowners minimise underwater noise emmisions when operating in sensitive environments.  Increased focus is being placed on underwater noise emissions from vessels and this is creating the need fr a means of controlling underwater noise radiation.  New international standards and regulations are anticipated, which will restrict acess to environmentally sensitive areas and limit the types of vessels callign at ports to only those complying with stringent noise level standards.

The importance of particle motion to fishes and invertebrates

Arthur N Popper and Anthony D Hawkins

This paper considers the importance of particle motion to fishes and invertebrates and the steps that need to be taken to improve knowledge of its effects.  It is aimed at scientists investigating the impact of sounds on fishes and invertebrates but it is also relevant to regulators, those preparing environmental impact assessments, and to industries creating underwater sound.  The overall aim of this paper is to ensure that proper attention is paid to particle motion as a stimulus when evaluating the effects of sound upon aquatic life.

Marine Scotland is to be involved in the EU-funded Joint Monitoring Programme for Ambient Noise North Sea (JOMOPANS)

The aim of this project is to develop a framework for a fully operational joint monitoring programme for ambient noise in the North Sea. Output will be the tools necessary for managers, planners and other stakeholders to incorporate the effects of ambient noise in theirassessment of the environmental status of the North Sea, and to evaluate measures to improve the environment. Jomopans is in its initial phases and will officially start the 1st of January 2018.
