(Ua) Scientific Diving Safety Manual
UNIVERSITY OF ALASKA (UA) SCIENTIFIC DIVING SAFETY MANUAL AVAILABLE ON-LINE AT: http://www.uaf.edu/sfos/research/scientific-diving/ Revised 2/2019 Page 1 FOREWORD Since 1951 the scientific diving community has endeavored to promote safe, effective diving through self-imposed diver training and education programs. Over the years, manuals for diving safety have been circulated between organizations, revised and modified for local implementation, and have resulted in an enviable safety record. This document represents the minimal safety standards for scientific diving at the present day. As diving science progresses so must this standard, and it is the responsibility of every member of the Academy to see that it always reflects state of the art, safe diving practice. The policies, procedures and standards set forth in this Scientific Diving Safety Manual are intended to govern the training and diving operations of all personnel participating in the Scientific Diving Program at the University of Alaska (UA). It applies to all divers operating under UA auspices, including visiting divers, and to those UA Fairbanks, UA Anchorage, and UA Southeast campus officers responsible for the administration of this scuba program.

THE NORTH STAR CHRONICLES – a Newsletter Primarily for the Model Railway Fraternity
THE NORTH STAR CHRONICLES – a newsletter primarily for the model railway fraternity Volume 7 no 6 June 2019 Editor: David Cairns e-mail: [email protected] Website for back copies: [email protected] Phone: +27 82 653 5642 Editorial The feature article this month is the Dinorwic Slate Museum and associated Llanberis Lake Railway. Because of space considerations Gary Smith’s ‘fleshing out’ of his museum project will be held over until next month. National Slate Museum/Dinorwic quarry/Llanberis Railway By way of introduction, at the turn of the twentieth century, Wales had two main industries – coal mining and slate extraction. At their peaks the former industry employed some 270000 people at 620 mines and the latter 17000. These quantities do not include the large numbers of people involved in the industries serving coal and slate – rail and ship transport etc. Apart from a few scattered operations involving small numbers, both industries have effectively closed. The effect on employment numbers and the communities that depended on them was catastrophic. Today Wales, particularly the western, middle and north areas, is one large recreation area for tourists. When I was there, not hundreds but thousands of people could be seen hiking and riding the many narrow gauge lines that exist in Wales and that was in April when there was still snow on the hilltops! In other words the death of traditional industries has been replaced with a vibrant new industry – tourism. 1 The National Slate Museum is located at Gilfach Ddu, Llanberis, in the disused workshops of the Dinorwic quarry. -
Railways List
A guide and list to a collection of Historic Railway Documents www.railarchive.org.uk to e mail click here December 2017 1 Since July 1971, this private collection of printed railway documents from pre grouping and pre nationalisation railway companies based in the UK; has sought to expand it‟s collection with the aim of obtaining a printed sample from each independent railway company which operated (or obtained it‟s act of parliament and started construction). There were over 1,500 such companies and to date the Rail Archive has sourced samples from over 800 of these companies. Early in 2001 the collection needed to be assessed for insurance purposes to identify a suitable premium. The premium cost was significant enough to warrant a more secure and sustainable future for the collection. In 2002 The Rail Archive was set up with the following objectives: secure an on-going future for the collection in a public institution reduce the insurance premium continue to add to the collection add a private collection of railway photographs from 1970‟s onwards provide a public access facility promote the collection ensure that the collection remains together in perpetuity where practical ensure that sufficient finances were in place to achieve to above objectives The archive is now retained by The Bodleian Library in Oxford to deliver the above objectives. This guide which gives details of paperwork in the collection and a list of railway companies from which material is wanted. The aim is to collect an item of printed paperwork from each UK railway company ever opened. -

Barker Thesis submittedfor the Degree of Doctor of Philosophy in Environmental Science Environment Department University of York August 2003 Abstract Coral reefsprovide many servicesand are a valuableresource, particularly for tourism, yet they are suffering significant degradationand pollution worldwide. To managereef tourism effectively a greaterunderstanding is neededof reef ecological processesand the impactsthat tourist activities haveon them. This study explores the impact of divers and snorkelerson the reefs of St. Lucia, West Indies, and how the reef environmentaffects tourists' perceptionsand experiencesof them. Observationsof divers and snorkelersrevealed that their impact on the reefs followed certainpatterns and could be predictedfrom individuals', site and dive characteristics.Camera use, night diving and shorediving were correlatedwith higher levels of diver damage.Briefings by dive leadersalone did not reducetourist contactswith the reef but interventiondid. Interviewswith tourists revealedthat many choseto visit St. Lucia becauseof its marineprotected area. Certain site attributes,especially marine life, affectedtourists' experiencesand overall enjoyment of reefs.Tourists were not alwaysable to correctly ascertainabundance of marine life or sedimentpollution but they were sensitiveto, and disliked seeingdamaged coral, poor underwatervisibility, garbageand other tourists damagingthe reef.

Training Objectives for a Diving Medical Physician
The Diving Medical Advisory Committee Training Objectives for a Diving Medicine Physician This guidance includes all the training objectives agreed by the Diving Medical Advisory Committee, the European Diving Technology Committee and the European Committee for Hyperbaric Medicine in 2011. Rev 1 - 2013 INTRODUCTION The purpose of this document is to define more closely the training objectives in diving physiology and medicine that need to be met by doctors already fully accredited or board-certified in a clinical speciality to national standards. It is based on topic headings that were originally prepared for a working group of European Diving Technology Committee (EDTC) and the European Committee of Hyperbaric Medicine (ECHM) as a guide for diving medicine some 20 years ago by J.Desola (Spain), T.Nome (Norway) & D.H.Elliott (U.K.). The training now required for medical examiners of working divers and for specialist diving medicine physicians was based on a EDTC/ECHM standard 1999 and subsequently has been enhanced by the Diving Medical Advisory Committee (DMAC), revised and agreed in principle by DMAC, EDTC and ECHM in 2010 and then ratified by EDTC and ECHM in 2011. The requirements now relate to an assessment of competence, the need for some training in occupational medicine, the need for maintenance of those skills by individual ‘refresher training’. Formal recognition of all this includes the need to involve a national authority for medical education. These objectives have been applied internationally to doctors who provide medical support to working divers. (Most recreational instructors and dive guides are, by their employment, working divers and so the guidance includes the relevant aspects of recreational diving. -
