    SCIENTIFIC AMERICAN FRONTIERS PROGRAM #1503 "Going Deep" AIRDATE: February 2, 2005 ALAN ALDA Hello and welcome to Scientific American Frontiers. I'm Alan Alda. It's said that the oceans, which cover more than two thirds of the earth's surface, are less familiar to us than the surface of the moon. If you consider the volume of the oceans, it's actually more than ninety percent of the habitable part of the earth that we don't know too much about. The main reason for our relative ignorance is simply that the deep ocean is an absolutely forbidding environment. It's pitch dark, extremely cold and with pressures that are like having a 3,000-foot column of lead pressing down on every square inch -- which does sound pretty uncomfortable. In this program we're going to see how people finally made it to the ocean floor, and we'll find out about the scientific revolutions they brought back with them. We're going to go diving in the Alvin, the little submarine that did so much of the work. And we're going to glimpse the future, as Alvin's successor takes shape in a small seaside town on Cape Cod. That's coming up in tonight's episode, Going Deep. INTO THE DEEP ALAN ALDA (NARRATION) Woods Hole, Massachusetts. It's one of the picturesque seaside towns that draw the tourists to Cape Cod each year. But few seaside towns have what Woods Hole has. For 70 years it's been home to the Woods Hole Oceanographic Institution — an organization that does nothing but study the world's oceans.

    Shark Mitigation and Deterrent Measures Submission 64

    The Efficacy and Regulation of Shark Mitigation and Deterrent Measures Submission to: Senate Environment and Communications References Committee by Peter Stephenson BSc., ADAS 2815.3, Master Class V February 2017 As a commercial diver and fisherman with over 35 years of diverse experience I write this submission due to my ever-increasing concerns about policies governing management of and research into shark populations. I began snorkelling at the age of 7 and was a keen spear fisherman and surfer for decades although I am currently no longer active in these sports. (partly due to increasing negative shark incidents) I have a BSc. In marine science from Flinders University and have completed a number of years of marine research. Over more than four decades I have spent tens of thousands of hours observing and studying the marine environment. In recent years, particularly after my friends Peter Clarkson and Greg Pickering were attacked by white sharks, I have been researching shark attacks, shark behaviour and the possible factors influencing negative shark/ human interactions. I have also witnessed aggressive shark behaviour first hand but have luckily escaped serious injury…. so far. I currently work as an abalone diver in the South Australian Central Zone Abalone Fishery. THIS IS A MAJOR WORKPLACE SAFETY ISSUE FOR ME! THE BAITING AND HARASSMENT OF SHARKS FOR TOURISM AND SCIENTIFIC RESEARCH Despite legislation deeming the berleying, baiting, approach and harassment of white sharks illegal, governments grant exemptions and licences to tourism operators and scientists to conduct these activities. Despite years of research and observation, the level of conditioning of sharks by repeated berleying and baiting is still poorly understood and documented.

    JOURNAL February 48 2013 At the Double A snowy Douaumont Please note that Copyright for any articles contained in this Journal rests with the Authors as shown. Please contact them directly if you wish to use their material. 1 Hello All An interesting article in the Times caught my eye a couple of weeks ago. Carrying the heading: ‘Dramatic boost for campaign to honour first black officer’, it covers the life of Walter Tull, a coloured professional footballer with Tottenham Hotspur and Northampton Town, who joined up in the ranks at the beginning of the War, enlisting in the 17th Battalion (1st Footballer’s), Middlesex Regiment as it came to be known, and was later commissioned, before being killed in March, 1918. The campaign referred to, asks the government to award him a posthumous Military Cross for his bravery, and indeed, he had been recommended for the MC for courageous acts undertaken some time before his death. But, one presumes that, given that a unit could only receive so many awards in a month, more meritorious acts were recognised, and so Walter Tull’s gallantry sadly went unrewarded. The award of a posthumous MC to a very brave man does sound like a nice idea, but in these specific circumstances is it not woolly-headed? Politically correct even? I think that it is both, and would set an unwelcome precedent. With the rationing of medals, whoever had to decide who should receive the six, shall we say, awards from ten recommendations had to make a judgement call, and these decisions were made at Brigade and Division level.

The SSC's Action Plans, Occasional Papers, newsletter Species and other publications are supported by a wide variety of generous donors including: The Sultanate of Oman established the Peter Scott IUCN/SSC Action Plan Fund in 1990. The Fund supports Action Plan development and implementation. To date, more than 80 grants have been made from the Fund to SSC Specialist Groups. The SSC is grateful to the Sultanate of Oman for its confidence in and support for species conservation worldwide. The Council of Agriculture (COA), Taiwan has awarded major grants to the SSC's Wildlife Trade Programme and Conservation Communications Programme. This support has enabled SSC to continue its valuable technical advisory service to the Parties to CITES as well as to the larger global conservation community. Among other responsibilities, the COA is in charge of matters concerning the designation and management of nature reserves, conservation of wildlife and their habitats, conservation of natural landscapes, coordination of law enforcement efforts as well as promotion of conservation education, research and international cooperation.

By way of catching up, we have produced a Summer double issue and have the good fortune to be able to publish with a color cover. Coinciding with the Santa Barbara relocation is the appointment, by the Board of Directors, of the first members of the HDS USA Advisory Board. This distinguished group of senior diving professionals, with extensive backgrounds in diving medicine, technical development, commercial, military and sports diving, bring in excess of 300 years of diving experience to the Society. Most of their biographies are the size of town phone directories, and have had to be severely edited for publication. We are honored and gratefulfortheir willing offers of service, and hope that we have done their biographies justice. Details start on page 4. The recently introduced, Founding Benefactor class of membership has proven to be very popular with over half of the thirty available memberships already taken. An opportunity still exists to acquire one of these unique memberships and details of it's benefits are noted on page 9. On the international front, the ongoing formation of the HDS USA as a nonprofit corporation has, by law, changed the conditions that govern our relationship with the HDS in UK.

The nature and orientation of the sedi- current velocities. From 538 m (the bottom of mentary structures, plus the combined observa- the traverse) to 222 m, there is a sloping, tions of several Aluminaut dives in the same smooth, rock surface veneered with sand, rip- area, indicate that the southward bottom ple-marked by northward bottom currents of counterflow is persistent and not a temporary 50 cm/sec or more. The middle, low velocity tidal reversal. An extensive sedimentary anti- zone, from 222 m to 76 m, exhibits a muddy cline in the west-central sector of the Straits slope of largely bank-derived material.
