Influence of the Spatial Pressure Distribution of Breaking Wave
Journal of Marine Science and Engineering Article Influence of the Spatial Pressure Distribution of Breaking Wave Loading on the Dynamic Response of Wolf Rock Lighthouse Darshana T.

(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. -
'British Small Craft': the Cultural Geographies of Mid-Twentieth
‘British Small Craft’: the cultural geographies of mid-twentieth century technology and display James Lyon Fenner BA MA Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy August 2014 Abstract The British Small Craft display, installed in 1963 as part of the Science Museum’s new Sailing Ships Gallery, comprised of a sequence of twenty showcases containing models of British boats—including fishing boats such as luggers, coracles, and cobles— arranged primarily by geographical region. The brainchild of the Keeper William Thomas O’Dea, the nautical themed gallery was complete with an ocean liner deck and bridge mezzanine central display area. It contained marine engines and navigational equipment in addition to the numerous varieties of international historical ship and boat models. Many of the British Small Craft displays included accessory models and landscape settings, with human figures and painted backdrops. The majority of the models were acquired by the museum during the interwar period, with staff actively pursuing model makers and local experts on information, plans and the miniature recreation of numerous regional boat types. Under the curatorship supervision of Geoffrey Swinford Laird Clowes this culminated in the temporary ‘British Fishing Boats’ Exhibition in the summer of 1936. However the earliest models dated back even further with several originating from the Victorian South Kensington Museum collections, appearing in the International Fisheries Exhibition of 1883. 1 With the closure and removal of the Shipping Gallery in late 2012, the aim of this project is to produce a reflective historical and cultural geographical account of these British Small Craft displays held within the Science Museum. -

Isles of Scilly Naturetrek Tour Report 14 - 21 September 2019 Porthcressa and the Garrison Red Squirrel Grey Seals Birdwatching on Peninnis Head Report & Images by Andrew Cleave Naturetrek Mingledown Barn Wolf's Lane Chawton Alton Hampshire GU34 3HJ UK T: +44 (0)1962 733051 E: [email protected] W: www.naturetrek.co.uk Tour Report Isles of Scilly Tour participants: Andrew Cleave (leader) plus 12 Naturetrek clients Summary Our early-autumn week on the Isles of Scilly was timed to coincide with the bird migration which is easily observed on the islands. Our crossings to and from Scilly on Scillonian III enabled us to see seabirds in their natural habitat, and the many boat trips we took during the week gave us close views of plenty of the resident and migrant birds which were feeding and sheltering closer to shore. We had long walks on all of the inhabited islands and as well as birds, managed to see some marine mammals, many rare plants and some interesting intertidal marine life. Informative evening lectures by resident experts were well received and we also sampled lovely food in many of the pubs and cafés on the islands. Our waterfront accommodation in Schooners Hotel was very comfortable and ideally placed for access to the harbour and Hugh Town. Day 1 Saturday 14th September We began our trip in Penzance harbour where we boarded Scillonian III for the crossing to Scilly. Conditions were fine for the crossing and those of us up on deck had good views of seabirds, including Gannets, Fulmars and winter-plumage auks as we followed the Cornish coast and then headed out into the Atlantic. -

It was a misty spring morning with poor visibility which represented no problem for the steamship but threatened to delay the journey of the tour members who had opted to travel to Scilly by air. With the World Gig Racing Championships taking place on the islands over the weekend I was expecting a full complement of passengers on the vessel but whilst it was undoubtedly busy the numbers were fewer than I feared. Eventually the ropes were cast off and we began the three hour sailing to St Mary’s, passing several summer plumaged Great Northern Divers before we had ventured far into Mount’s Bay. Others were observed on the flat calm sea as we drew opposite Newlyn and in total at least six birds were noted, most in summer or partial summer dress. We were scanning for Basking Sharks but sadly none were seen although just a month later over 40 were counted between Penzance and Land’s End! As we made our way parallel with the South Cornish coast the cliffs were barely visible in the mist becoming more and more indistinct as our route took us further out to sea. -

The Isles of Scilly April 27Th to May 5Th 2018
SANDWICH BAY BIRD OBSERVATORY HOLIDAYS THE ISLES OF SCILLY APRIL 27TH TO MAY 5TH 2018 Tresco from Halangy Down -------------------------------------------------------------------------------------------------------------------------- Friday April 27th : The journey down and the crossing on ‘The Scillonian’ Most of the group had assembled at the Bird Observatory the previous evening for the overnight coach journey down to Penzance, picking Erica Wells up at Hatton Cross en route and with a couple of comfort stops at service stations on the way. Most people got at least some sleep on the journey. The weather was not very good, with relentless rain all night, which only eased after dawn as we arrived in Penzance. We had also received news that the ferry crossing was going to be delayed due to the strong winds forecast for around the Land’s End area and the state of the tide. So, we had to kill time in Penzance for a few hours before embarking at 10.45 and sailing at about 12 noon. A nice male Common Eider in the Penzance inner harbour was a pleasant sight, as always. It is a solitary bird which seems completely lost and has been resident around the harbour for several years now. The group was made up to its full complement as Peter Roberts joined us on the quayside, having made his own way down to Penzance from his home on Islay in Scotland. The two and a half hour crossing to Hugh Town on St. Mary’s was forecasted as going to be rough, with a steady south-east wind swinging round to the north-east during the journey.
