As shipping, recreational boating and energy exploration have increased along coastlines, offshore and in deep ocean environments, concern has been raised about the impact of noise from these activities. Research has established that such noise can travel long distances underwater, and scientific attention has focused on how changes in ocean noise levels could cause effects in coastal and offshore habitats, affecting marine mammals.

There have been claims that higher noise levels can reduce the ability of animals to communicate and reduce their ability to hear, affecting survival, finding food, and navigating to preferred habitats.

There is also concern about the underwater impact of the construction of proposed wind farms.

The International Maritime Organisation (IMO), the maritime agency of the United Nations, which is responsible for regulating shipping, is taking action in regard to noise from ships. Its remit includes maritime safety, environmental concerns, legal matters, technical cooperation, maritime security and shipping efficiency.

It has called a meeting about underwater noise from ships for its headquarters in London this month.

A ‘Workshop on the Relationship between Energy Efficiency and Underwater Radiated Noise from Ships’ will be held on September 18 and 19. This follows the IMO's Marine Environment Protection Committee approved revised guidelines for “Reduction of underwater radiated noise from shipping to address adverse impacts on marine life’ in July.

The IMO says the Workshop will include discussions on how noise emissions can be reduced, what design and technology changes may be needed in shipping, operational measures to reduce overall emissions and other related areas.

It will run from 9.30 a.m. to 5.30 p.m. each day and also be available online.

Registration details are on the IMO website

#POWER FROM THE SEA - The Sustainable Energy Authority of Ireland (SEAI) is teaming with IBM in a new project to assess the noise levels of wave energy devices off the Irish coast.
The scheme will see an array of noise sensing equipment such as hydrophones deployed in Galway Bay to monitor the noise levels of wave energy conversion devices in real time, as well as map patterns of marine life in the area.
According to AOL Energy, noise pollution at sea is a chief concern, having a disturbing effect on fish migrations among other marine ecosystems.
The west of Ireland will prove an important case study in this regard, as it hosts one of the world's largest wave energy infrastructures.
"Underwater noise is a global environmental issue that has to be addressed if we are going to take advantage of the huge potential of ocean energy," said EU Commissioner for Research, Innovation and Science, Maire Geoghegan-Quinn.

Marine Leisure & Aquatic Tourism

Domestic coastal tourism expenditure was approximately €698 million in 2018, while domestic marine tourism generated €381 million.

Activities such as walking/ running along the coast, swimming and beach visitations are among the most popular activities for domestic visitors on both day and overnight trips.

While participation rates in pursuits such as bird and wildlife watching in coastal areas and visiting nature reserves, etc. in coastal areas were lower, these activities did see the highest frequency of both day and overnight trips for those active in these activities. 

According to the National University of Galway (NUIG) research the average expenditure per coastal day trip in 2018 was calculated at €95. The equivalent for coastal overnight trips was €310. The estimated water-based activity expenditure per person per trip across the sample was €56 rising to €73 for the subsample that actually undertake waterbased activities on their coastal visits. The results also indicate that domestic tourists undertake the majority of their marine activities on the West and South coasts of Ireland and that there are notable differences in participation rates across age groupings, social classes and by family makeup.

A domestic tourist is defined in this report as a person who spends at least one night away from home on their trip. Total expenditure by domestic tourists in coastal areas was estimated to be €698 million in 2018, which represents 35% of the total expenditure by domestic tourists (using the broader Fáilte Ireland measure for domestic tourists that includes business trips equating to 10.92 million in total trips and €2,006 million in total revenue).

The marine-related activity expenditure, or what might truly be referred to as domestic marine tourism, is estimated to generate revenue of €381 million with €172 million being spent on water-based activities. Marine tourism makes up an estimated 19% of total domestic tourism expenditure.

Marine Leisure Tourism - FAQ

Coastal tourism refers to land-based and water-based tourism activities taking place on the coast for which the proximity to the sea is a condition including also their respective services. Coastal and Marine Tourism & Leisure are seen as one of the Blue Economy (BE) sectors that can help unlock the potential of multi-use of space at sea by engaging with Blue Growth (BG) sectors such as Aquaculture and Marine Renewable Energy among others.

Sports: sailing, surfing, diving and fishing Heritage: Unesco coastal villages, archaeological sites of interest, biospheres and historical points of interest Arts: coastal museums, art galleries, museums, wrecks Education: Eco-tourism, field courses, NGOs. Food: Seafood restaurants, Seafood festivals

NUI Galway carried out a survey of domestic residents in Ireland in 2019 as part of a survey entitled "Valuing and understanding the dynamics of Ireland's Ocean Economy". The purpose of the household survey was to profile the domestic market for single-day trips (leisure) and overnight trips (tourism) for coastal and marine-related activities in Ireland. The results of the survey are also used to estimate what proportion of an Irish resident's total domestic tourism expenditure is in coastal areas (coastal tourism) and what proportion is spent on undertaking marine-related activities (marine tourism).

The NUI results highlight the important contribution that Ireland's marine and coastal resources make to the leisure experiences of the general population and the importance of the domestic tourism market to local coastal economies. The analysis indicates that domestic coastal tourism expenditure was approximately €698 million in 2018, while domestic marine tourism generated €381 million. Activities such as walking/ running along the coast, swimming and beach visitations are among the most popular activities for domestic visitors on both day and overnight trips. While participation rates in pursuits such as bird and wildlife watching in coastal areas and visiting nature reserves, etc. in coastal areas were lower, these activities did see the highest frequency of both day and overnight trips for those active in these activities. Satisfaction with the available marine-related leisure facilities was also found to be very high across all activities.
