Executive Summary Background Race Rocks (XwaYeN), located 17 km southwest of Victoria in the Strait of Juan de Fuca, consists of nine islets, including the large main island, Great Race. Named for its strong tidal currents and rocky reefs, the waters surrounding Race Rocks (XwaYeN) are a showcase for Pacific marine life. This marine life is the result of oceanographic conditions supplying the Race Rocks (XwaYeN) area with a generous stream of nutrients and high levels of dissolved oxygen. These factors contribute to the creation of an ecosystem of high biodiversity and biological productivity. In 1980, the province of British Columbia, under the authority of the provincial Ecological Reserves Act, established the Race Rocks Ecological Reserve. This provided protection of the terrestrial natural and cultural heritage values (nine islets) and of the ocean seabed (to the 20 fathoms/36.6 meter contour line). -

DRAFT Sustainable Tourism for Marine Recreation Providers
DRAFT Sustainable Tourism for Marine Recreation Providers Wolcott Henry photo The Coral Reef Alliance: Coral Parks Program Education Series ©2004 Sustainable Tourism Introduction In this era of the global economy, tourism has become a primary source of revenue for many regions of the world, generating nearly $500 billion in worldwide revenues in 2001, and continuing to grow (WTO, 2001). The United Nations Environment Program (UNEP) facilitated a study that points out that the tourism industry now represents more than 10% of the world’s gross domestic product (UNEP, 2002). While tourism brings significant benefits for both local and global economies, its rapid growth and development in recent decades has caused widespread social and environmental change across the globe, particularly in popular coastal resort destinations. In contrast, the concept of sustainable tourism is now seen as a way to promote socio-economic development in a given region while simultaneously protecting local culture and the natural environment. In order to address these issues and how they impact coral reefs, the Coral Reef Alliance (CORAL) has compiled this Sustainable Tourism for Marine Recreation Providers handbook. In an effort to promote sustainable tourism, the information contained in this handbook highlights some of the current environmental problems associated with tourism growth and development, and promotes practical solutions for marine recreation providers to adopt good environmental practices. We encourage readers to provide us with feedback as to how we can improve this publication.

A Coral-Safe Diving Reminder Reduces Reef Contacts by Ashton
PROTECTING GUAM’S CORAL REEFS BY IMPROVING SCUBA DIVER BEHAVIOR: A CORAL-SAFE DIVING REMINDER REDUCES REEF CONTACTS BY ASHTON N. WILLIAMS A thesis submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN BIOLOGY SUPERVISORY COMMITTEE Dr. Laurie Raymundo, Chair Dr. Alexander Kerr, Member Dr. Romina King, Member UNIVERSITY OF GUAM DECEMBER 2019 Abstract Coral reefs are a critical resource for the culture and economy of the American territory of Guam, but the island’s coral reef resources are increasingly imperiled by climate change, particularly bleaching caused by rising seawater temperatures. Severe bleaching events in 2013, 2014, 2016, and 2017 have caused mass mortality of corals and made evident the critical need to reduce local stressors to protect the future of Guam’s reefs. An estimated 300,000 people scuba dive on Guam’s reefs annually, but the impacts of these divers are unknown. This study examines the impacts of scuba diving activity on highly trafficked coral reefs and tests a low-effort approach to reducing diver impacts by using a coral-safe diving reminder. Comparisons of benthic cover, genus diversity, and health impacts did not reveal any significant differences between pairs of often dived and rarely dived sites, although it is likely that the damage and mortality caused by recent bleaching events may be masking the smaller impacts of scuba divers. A single-sentence coral-safe diving reminder delivered as part of the standard pre-dive briefing was highly effective in reducing both accidental and intentional contacts with reef. Divers who received a coral-safe diving reminder made 72% fewer contacts with the reef, and about 60% fewer contacts with live corals specifically, than divers who did not receive a reminder. -
Technologies for Underwater Archaeology and Maritime Preservation
Technologies for Underwater Archaeology and Maritime Preservation September 1987 NTIS order #PB88-142559 Recommended Citation: U.S. Congress, Office of Technology Assessment, Technologies for Underwater Archaeol- ogy and Maritime Preservation— Background Paper, OTA-BP-E-37 (Washington, DC: U.S. Government Printing Office, September 1987). Library of Congress Catalog Card Number 87-619848 For sale by the Superintendent of Documents U.S. Government Printing Office, Washington, DC 20402-9325 (order form on the last page of this background paper) Foreword Exploration, trading, and other maritime activity along this Nation’s coast and through its inland waters have played crucial roles in the discovery, settlement, and develop- ment of the United States. The remnants of these activities include such varied cul- tural historic resources as Spanish, English, and American shipwrecks off the Atlantic and Pacific coasts; abandoned lighthouses; historic vessels like Maine-built coastal schooners, or Chesapeake Bay Skipjacks; and submerged prehistoric villages in the Gulf Coast. Together, this country’s maritime activities make up a substantial compo- nent of U.S. history. This background paper describes and assesses the role of technology in underwater archaeology and historic maritime preservation. As several underwater projects have recently demonstrated, advanced technology, often developed for other uses, plays an increasingly important role in the discovery and recovery of historic shipwrecks and their contents. For example, the U.S. Government this summer employed a powerful remotely operated vehicle to map and explore the U.S.S. Monitor, which lies on the bottom off Cape Hatteras. This is the same vehicle used to recover parts of the space shuttle Challenger from the ocean bottom in 1986. -
Safe Diving Distances from Transmitting Sonar, from the US Navy Diving Manual
APPENDIX 1A 6DIH'LYLQJ'LVWDQFHVIURP 7UDQVPLWWLQJ6RQDU 1A-1 INTRODUCTION The purpose of this appendix is to provide guidance regarding safe diving distances and exposure times for divers operating in the vicinity of ships transmit- ting with sonar. Table 1A-1 provides guidance for selecting Permissable Exposure Limits Tables; Table 1A-2 provides additional guidance for helmeted divers. Tables 1A-3 through 1A-5 provide specific procedures for diving operations involving AN/SQS-23, -26, -53, -56; AN/SQQ-14, -30, and -32; AN/BSY-1, -2; and AN/BQQ-5 sonars. Section 1A-6 provides guidance and precautions concerning diver exposure to low-frequency sonar (160-320Hz). Contact NAVSEA Supervisor of Diving (00C3B) for guidance on other sonars. This appendix has been substantially revised from Safe Diving Distances from Trans- mitting Sonar (NAVSEAINST 3150.2 Series) and should be read in its entirety. 1A-2 BACKGROUND Chapter 18 of OPNAVINST 5100.23 Series is the basic instruction governing hearing conservation and noise abatement, but it does not address exposure to waterborne sound. Tables 1A-3 through 1A-6 are derived from experimental and theoretical research conducted at the Naval Submarine Medical Research Labora- tory (NSMRL) and Naval Experimental Diving Unit (NEDU). This instruction provides field guidance for determining safe diving distances from transmitting sonar. This instruction supplements OPNAVINST 5100.23 Series, and should be implemented in conjunction with OPNAVINST 5100.23 Series by commands that employ divers. The Sound Pressure Level (SPL), not distance, is the determining factor for estab- lishing a Permissible Exposure Limit (PEL). The exposure SPLs in Tables 1A-3 through 1A-6 are based upon the sonar equation and assume omni-directional sonar and inverse square law spreading. -

Paula Hershkowitz 1 ABSTRACT The thesis focuses on the martyr poetry of Prudentius. It argues that we cannot fully understand his verses without contextualising the poet within his physical environment, in particular that of Hispania, his homeland. Although literary sources can provide information about Prudentius and his work, it is only by accessing evidence from the archaeological and visual record when studying his poetry that its purpose can be fully understood. Chapter I serves as an introduction to Prudentius. It examines the information he gives us about himself in his poetry and discusses the historical context and background of his work. Chapter II identifies the audience of Prudentius and proposes a role for him as villa-poet to the elite of Hispania. It questions the extent to which this audience were, during his lifetime, committed to the Christian religion. Chapter III analyses the martyr poems in detail, especially those located in Hispania. By examining the material evidence for martyr worship in the locations mentioned by Prudentius it assesses whether the cult of the martyrs played a significant role in the lives of the Spanish. -

The Complete Diving System 2 Divator Product Overview
PRODUCT OVERVIEW DIVATOR THE COMPLETE DIVING SYSTEM 2 DIVATOR PRODUCT OVERVIEW A tragic bus accident in Sweden after the Second World War raised the concern that divers could not be quickly deployed to the crash site. The Swedish government asked Interspiro (“AGA” at that time) if they could provide a rapid deployment diving device for search and rescue operations. Interspiro began an extensive research program and in 1948 the Worlds first underwater breathing apparatus for search and rescue was presented to the Swedish authorities. The device, commonly referred to as the “iron bed” (because of the shape of the carrying frame), featured a breathing valve with inhalation and exhalation in the same diaphragm. The first of many Interspiro innovations in the field of diving. Today, over 60 years later, the latest generation of Interspiro SCUBA – DIVATOR – is still the preferred choice for professional divers around the World. The Interspiro diving philosophy is a system approach. The reason is simple and obvious, to obtain the highest possible safety level for professional divers. © 2015 Interspiro AB, Sweden.
