(2019), Antonini et al. (2019). Due to the peculiar bathymetries and topographies of rock pinnacles, there is no dedicated formula to properly quantify the loads induced by the breaking waves on offshore rock lighthouses. Wienke’s formula (Wienke and Oumeraci (2005) was used in this study to estimate the loads, even though it was not derived for breaking waves on offshore rock lighthouses, but rather for the breaking wave loading on offshore monopiles. -

Accounting for the Fund The Companies Act 1985 does not apply to all public bodies but the principles that underlie the Act’s accounting and disclosure requirements are of general application: their purpose is to give a true and fair view of the state of affairs of the body concerned. The Government therefore has decided that the accounts of public bodies should be prepared in a way that conforms as closely as possible with the Act’s requirements and also complies with Accounting Standards where applicable. The accounts are prepared in accordance with accounts directions issued by the Secretary of State for Transport. The Fund’s accounts consolidate the General Lighthouse Authorities’ (GLAs) accounts and comply as appropriate with this policy. The notes to the Bishop Rock Lighthouse accounts contain further information. Section 211(5) of the Merchant Shipping Act 1995 requires the Secretary of State to lay the Fund’s accounts before Parliament. -
THE TRINITY HOUSE LUNDY ARCHIVE: a PAPER in MEMORY of the LIGHTHOUSE KEEPERS of LUNDY by R.W.E
Rep. Lundy Field SOc. 44 THE TRINITY HOUSE LUNDY ARCHIVE: A PAPER IN MEMORY OF THE LIGHTHOUSE KEEPERS OF LUNDY By R.W.E. Farrah 4, Railway Cottages, Long Marton, Appleby, Cumbria CAI6 6BY INTRODUCTION The approaches to the Bristol Channel along the northern coast of Cornwall and Devon offer very little shelter for the seafarer during severe weather conditions. Lundy, however, situated at the mouth of the Channel central to the busy sea lanes, is one exception and has provided an important refuge on the leeward side of the island throughout the historic period. Before the navigational aids of the lighthouses were built, the island must also have proved hostile to the mariner, especially during hours of darkness and poor visibility. The number of shipwrecks and marine disasters around the island bear testimony to this. The dangers were considerable; although the tidal streams to the west of Lundy are moderate, they are strong around the island. There are several bad races, to the north-east (The White Horses), the north-west (T)1e Hen and Chickens) and to the south-east. There are also overfalls over the north-west bank. Some appreciation of the dangers the island posed can be seen from the statistics issued by a Royal Commission of 1859 who were reporting on a harbour refuge scheme. They noted that: "out of 173 wrecks in the Bristol Channel in 1856-57, 97 received their damage and 44 lives were lost east of Lundy; while 76 vessels were lost or damaged and 58 lives sacrificed west of Lundy, thus showing the island to be nearly in the centre of the dangerous parts" (quoted in Langham A and M, 1984,92). -

The Development of Key Characteristics of Welsh Island Cultural Identity and Sustainable Tourism in Wales
SCIENTIFIC CULTURE, Vol. 3, No 1, (2017), pp. 23-39 Copyright © 2017 SC Open Access. Printed in Greece. All Rights Reserved. DOI: 10.5281/zenodo.192842 THE DEVELOPMENT OF KEY CHARACTERISTICS OF WELSH ISLAND CULTURAL IDENTITY AND SUSTAINABLE TOURISM IN WALES Brychan Thomas, Simon Thomas and Lisa Powell Business School, University of South Wales Received: 24/10/2016 Accepted: 20/12/2016 Corresponding author: [email protected] ABSTRACT This paper considers the development of key characteristics of Welsh island culture and sustainable tourism in Wales. In recent years tourism has become a significant industry within the Principality of Wales and has been influenced by changing conditions and the need to attract visitors from the global market. To enable an analysis of the importance of Welsh island culture a number of research methods have been used, including consideration of secondary data, to assess the development of tourism, a case study analysis of a sample of Welsh islands, and an investigation of cultural tourism. The research has been undertaken in three distinct stages. The first stage assessed tourism in Wales and the role of cultural tourism and the islands off Wales. It draws primarily on existing research and secondary data sources. The second stage considered the role of Welsh island culture taking into consideration six case study islands (three with current populations and three mainly unpopulated) and their physical characteristics, cultural aspects and tourism. The third stage examined the nature and importance of island culture in terms of sustainable tourism in Wales. This has involved both internal (island) and external (national and international) influences. -

ESC IN WALES, United Kingdom Flat Holm Island Volunteer Role Description: Trainee Assistant Warden March 2021 for 10 months Volunteers from Estonia, Germany, France, Spain, Czech Republic, Belgium and Austria are eligible to apply __________________________________________________________________ Host project Cardiff Council is a local authority employing approx. 15000 employees. Cardiff Harbour Authority is a department within Cardiff Council that manages Flat Holm Island. Flat Holm is a small island 5 miles off the Cardiff coast and is a Site of Special Scientific Interest, Local Nature Reserve, Historic site and visitor destination. Its main aim is to conserve the natural habitats, plants and wildlife, historic features and provide opportunities for people in its widest sense including volunteering and learning new skills. We welcome volunteers on our long term Voluntary Assistant Warden Scheme where training in heritage management, habitat management and nature conservation, wildlife monitoring/surveys and environmental education/visitor management is offered. The island welcomes day trippers to our visitor centre in the Victorian barracks (grey stone building in the photo) who are provided with guided tours and there is also dormitory accommodation, camping and a converted Lighthouse keeper’s cottage available for overnight stays for visitors which include individuals, families, youth groups, special interest groups etc who can get involved in activities such as conservation, retreats, education survival skills and more. Whilst on the Island, volunteers live in a converted World War 2 accommodation block during summer (white building shown in the above photo) and in the farmhouse dormitories during winter (photo on left). The island is also supported by a voluntary ‘Friends of’ group called the Flat Holm Society. -

Analysing Clipped Sea-Level Records for Harmonic Tidal Constituents
ANALYSING CLIPPED SEA-LEVEL RECORDS FOR HARMONIC TIDAL CONSTITUENTS by J.J. EVANS and D.T. PUGHUI Coastal sea-level measurements must sometimes be made at sites where the gauge dries out at low levels. By progressively removing the lower part of a tidal record, and analysing the remainder with the conventional least-squares criteria, we have obtained stable values of the principal constants until only half of the original range remained. This stability has implications for the definitions of tidal constants and of mean sea level in regions of very shallow water and drying banks. INTRODUCTION As part of a recent survey of tidal conditions in the Severn Estuary and Bristol Channel (Alcock and Pu g h ) [1], it was necessary to install a sea-level recorder on the island of Flat Holm, with a zero level 2.8 m above Lowest Astronomical Tide. The gauge therefore dried out for the lowest part of the large spring range (10.5 m) which occurs in the area. In order to compare the data from Flat Holm with those from contemporary bottom pressure records at Lavernock Point and Steep Holme, 4.0 km northwest and 5.0 km south of Flat Holm respectively, harmonic tidal analyses were made of the data at all three sites. ANALYSES Following the usual practice, harmonic constituents were determined by fitting the function : T(t) = Zo + iNHnfn COS (ant ~ g„ + V n + U„) (*) Institute of Oceanographic Sciences, Bidston Observatory, Birkenhead, Merseyside, U.K. where Zo is mean sea level or pressure, H„ and g„ are the amplitude and phase of the constituent, 'Tr, is the constituent speed, and V,„ u„ and f„ are astronomical arguments (See, for example, M lrra y )[5], [6], The parameters were fitted subject to the conditions that ER2(t) is a minimum, where R(t) = 0(t) - T(t) and 0(0 is the observed level or pressure.
