E 17 July 2007 Severnside Branch SSaabbrriinnaa TTiimmeess Branch Organiser's Bit I have just reviewed my last piece for the newsletter and find I made a comment about how the weather would surely be better for our May fieldtrip. How wrong I was! Although the day before had been lovely, Sunday 13th May was very overcast and wet. The Cat's Back was not visible through the cloud but I was impressed by the number of members who turned out in such weather. It was great to see you all. Also, well done and thank you to Duncan who was able to offer us an alternative, lower route, avoiding the cloud if not the rain, and still filled the day with interesting Ever wonder where the exposures. “Sabrina” name comes Our trip to Flat Holm in June was fully booked; from?

From the beginning I had an interest to work aboard with macroalgae, after talking with prof. Isabel Sousa Pinto about this interest, she immediately suggested me a few places that I could look over. One of the suggestions was SINTEF ocean where I got to know Jorunn Skjermo. The door to Jorunn’s office was always open whenever I ran into a trouble spot or had a question about my research. She consistently allowed this study to be my own work, but steered me in the right the direction whenever she thought I needed it. Thank you!! I want to thank Isabel Azevedo, Silje Forbord and Kristine Steinhovden for all the guidance provided in the beginning and until the end of my internship. I would also like to thank the experts who were involved in the different subjects of my research project: Arne Malzahn, Torfinn Solvang-Garten, Trond Storseth and to the amazing team of SINTEF ocean. I also want to thank my master’s director professor Paula Melo, who was a relentless person from the first day, always taking care of her “little F1 plants”. A huge thanks to my fellows Mónica Costa, Fernando Pagels and Leonor Martins for all the days and nights that we spent working and studying hard. -

Kelp Aquaculture
Aquaculture in Shared Waters Kelp Aquaculture Sarah Redmond1 ; Samuel Belknap2 ; Rebecca Clark Uchenna3 “Kelp” are large brown marine macroalgae species native to New England and traditionally wild harvested for food. There are three commercially important kelp species in Maine—sugar kelp (Saccharina latissima), winged kelp (Alaria esculenta), and horsetail kelp (Laminaria digitata). Maine is developing techniques for culturing kelp on sea farms as a way for fishermen and farmers to diversify their operations while providing a unique, high quality, nutritious vegetable seafood for new and existing markets. Kelp is grown on submerged horizontal long lines on leased sea farms from September to May, making it a “winter crop” for Maine. The simple farm design, winter season, and relatively low startup costs allow for new and existing sea farmers to experiment with this newly developing type of aquaculture on Maine’s coast. “Kelp” can refer to sugar kelp (Saccharina latissima), Alaria (Alaria esculenta), or horsetail kelp (Laminaria digitata). Sugar kelp has been cultivated in Maine for several years, and successful experimental cultivation has been done with species such as Alaria. These photos are examples of the cultivation stages of sugar kelp.

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. -

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.
