Following his B.Sc. from the University of Birmingham, UK (1961) and Ph.D. from the University of Ottawa (1964), and a NATO Research Fellowship at the University of Wales, Chris started his academic career at the University of Waterloo, Ontario in 1965, serving as Chair of Earth Sciences from 1975 to 1981. In a similar position at Memorial University of Newfoundland (1981-87), he merged geology and geophysics and established the Centre of Earth Resources Research. From 1987-1989, as Director General, Sedimentary and Marine Branch, Geological Survey of Canada, he managed four regional offices and also the offshore Frontier Geoscience Program on all three coasts. At the University of Victoria, Chris was Director of the Centre of Earth and Ocean Research (1989-2000), founded the School of Earth and Ocean Sciences (1991-2002), and then served as the founding Director of NEPTUNE Canada (2001-2011), the world’s first regional cabled ocean observatory (800km; $150M).<br />Chris has served on many boards and councils, including as President of the Geological Association of Canada, the Canadian Geoscience Council, and the Academy of Science of the Royal Society of Canada; as Group Chair of both Earth Sciences and Interdisciplinary for the Natural Sciences and Engineering Research Council of Canada (NSERC), and three separate terms as Chair of the Council of Canadian Earth Science Departments. He has been a member of the Canadian Nuclear Safety Commission (14 years), the International Ocean Drilling Program, the International Commission on Stratigraphy and the BC Science Council. <br /><br />He was the first Chair of the United Nations ITU-WMO-UNESCO IOC Joint Task Force on SMART submarine telecommunications cables for ocean climate monitoring and (tsunami) disaster warning (2012-16). He continues to serve on the Science Advisory Committees of both the Canadian Ocean Tracking Network and the Canary Islands Ocean Observatory. <br />Chris’ research focuses on understanding Early Paleozoic oceans, climate and life, principally using conodont micropaleontology, stratigraphy, and isotope geochemistry, with nearly 200 publications and 250 conference abstracts. <br />For his various contributions, he was awarded the J. Willis Ambrose, Elkanah Billings, and Past Presidents medals of the Geological Association of Canada (GAC), the Bancroft Award (Royal Society of Canada), the Pander Society Medal, the Micropalaeontological Society’s Brady Medal, the Queen’s Golden and Diamond Jubilee Medals, and an Honorary D.Sc. from the University of Waterloo and Memorial University of Newfoundland. He is a Fellow of the Royal Society of Canada (RSC), the National Academy of Sciences, Cordoba, Argentina, and was appointed to the Order of Canada.<br /><div class="js-profile-less-about u-linkUnstyled u-tcGrayDarker u-textDecorationUnderline u-displayNone">less</div></div></div><div class="ri-section"><div class="ri-section-header"><span>Interests</span><a class="ri-more-link js-profile-ri-list-card" data-click-track="profile-user-info-primary-research-interest" data-has-card-for-ri-list="15974665">View All (6)</a></div><div class="ri-tags-container"><a data-click-track="profile-user-info-expand-research-interests" data-has-card-for-ri-list="15974665" href="https://www.academia.edu/Documents/in/Oceanography"><div id="js-react-on-rails-context" style="display:none" data-rails-context="{"inMailer":false,"i18nLocale":"en","i18nDefaultLocale":"en","href":"https://uvic.academia.edu/ChristopherBarnes","location":"/ChristopherBarnes","scheme":"https","host":"uvic.academia.edu","port":null,"pathname":"/ChristopherBarnes","search":null,"httpAcceptLanguage":null,"serverSide":false}"></div> <div class="js-react-on-rails-component" style="display:none" data-component-name="Pill" data-props="{"color":"gray","children":["Oceanography"]}" data-trace="false" data-dom-id="Pill-react-component-8521d9d3-adee-439b-9e6c-7ae444b49f97"></div> <div id="Pill-react-component-8521d9d3-adee-439b-9e6c-7ae444b49f97"></div> </a><a data-click-track="profile-user-info-expand-research-interests" data-has-card-for-ri-list="15974665" href="https://www.academia.edu/Documents/in/Marine_Science"><div class="js-react-on-rails-component" style="display:none" data-component-name="Pill" data-props="{"color":"gray","children":["Marine Science"]}" data-trace="false" data-dom-id="Pill-react-component-6a01310b-2ba2-47b9-9415-c86c34fb0360"></div> <div id="Pill-react-component-6a01310b-2ba2-47b9-9415-c86c34fb0360"></div> </a><a data-click-track="profile-user-info-expand-research-interests" data-has-card-for-ri-list="15974665" href="https://www.academia.edu/Documents/in/Education"><div class="js-react-on-rails-component" style="display:none" data-component-name="Pill" data-props="{"color":"gray","children":["Education"]}" data-trace="false" data-dom-id="Pill-react-component-51714b20-3aea-4ca4-acaa-e449272c4604"></div> <div id="Pill-react-component-51714b20-3aea-4ca4-acaa-e449272c4604"></div> </a><a data-click-track="profile-user-info-expand-research-interests" data-has-card-for-ri-list="15974665" href="https://www.academia.edu/Documents/in/Business"><div class="js-react-on-rails-component" style="display:none" data-component-name="Pill" data-props="{"color":"gray","children":["Business"]}" data-trace="false" data-dom-id="Pill-react-component-362c64b1-530c-43ad-bcca-867232e0f451"></div> <div id="Pill-react-component-362c64b1-530c-43ad-bcca-867232e0f451"></div> </a><a data-click-track="profile-user-info-expand-research-interests" data-has-card-for-ri-list="15974665" href="https://www.academia.edu/Documents/in/Sociology"><div class="js-react-on-rails-component" style="display:none" data-component-name="Pill" data-props="{"color":"gray","children":["Sociology"]}" data-trace="false" data-dom-id="Pill-react-component-43d5dc34-0754-49d2-9110-fdf7843cf4fe"></div> <div id="Pill-react-component-43d5dc34-0754-49d2-9110-fdf7843cf4fe"></div> </a></div></div></div></div><div class="right-panel-container"><div class="user-content-wrapper"><div class="uploads-container" id="social-redesign-work-container"><div class="upload-header"><h2 class="ds2-5-heading-sans-serif-xs">Uploads</h2></div><div class="documents-container backbone-social-profile-documents" style="width: 100%;"><div class="u-taCenter"></div><div class="profile--tab_content_container js-tab-pane tab-pane active" id="all"><div class="profile--tab_heading_container js-section-heading" data-section="Papers" id="Papers"><h3 class="profile--tab_heading_container">Papers by Christopher R .

The present study is mainly based on 17 samples containing more than 17 000 conodont elements from an approximately 14-m-thick succession of the Sholeshook Limestone Formation in a road cut near Whitland, South Wales, that yielded a diverse fauna of more than 40 taxa. It is dominated by representatives of Amorphognathus, Aphelognathus/Plectodina and Eocarniodus along with several coniform taxa. Representatives of Decoriconus, Istorinus and Sagittodontina are reported from the Ordovician of UK for the first time. The fauna is a typical representative of the British Province of the Atlantic Realm and includes a mixture of taxa of North American, Baltoscandic and Mediterranean affinities along with pandemic species. Based on the presence of many elements of Amorphognathus ordovicicus and some morphologically advanced specimens of Amorphognathus superbus, the Sholeshook Limestone Formation is referred to the lower A. ordovicicus Zone. Most of the unit is also coeval with Zone 2 of the Cautleyan Stage in the British regional stage classification, and stage slice Ka3 of the middle Katian Stage in the global stratigraphical classification, an age assignment consistent with data from trilobites, graptolites and chitinozoans. The unusually large collection of M elements of Amorphognathus provides insight into the complex morphological variation in this element of some Katian species of this genus. The Sholeshook conodont fauna is similar to those of the Crug and Birdshill limestones, but differs in several respects from the slightly older ones from the Caradocian type area in the Welsh Borderland. Although having some species in common, the Sholeshook conodont fauna clearly differs from coeval Baltoscandic faunas and is even more different in composition compared with equivalent North American Midcontinent faunas</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="123560072"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="123560072"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 123560072; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=123560072]").text(description); $(".js-view-count[data-work-id=123560072]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 123560072; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='123560072']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 123560072, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=123560072]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":123560072,"title":"Data from: Katian (Upper Ordovician) conodonts from Wales.

The stratigraphy of the Kechika Formation, Road River Group and Skoki Formation in northern British Columbia has been described previously during reconnaissance mapping. This study provides detailed stratigraphic descriptions of Upper Cambrian to Lower Silurian units from 9 key sections which span an east-west transect from the Macdonald Platform to the Kechika Trough, and 3 sections across the parautochthonous Cassiar Terrane. The transect lies within an interpreted upper plate of an asymmetrically rifted margin. Regionally, renewed phases of extension of the margin throughout the lower Paleozoic are recorded in abrupt lateral and vertical facies changes and pulses of volcanism. The tectono-stratigraphic framework was influenced by eustatic sea-level changes. Revised stratigraphic terminology proposed herein includes the division of the Kechika Formation into 5 formal members: the Lloyd George, Quentin, Grey Peak, Haworth and Mount Sheffield members. The Skoki Formation comprises three distinct, formal members defined as the Sikanni Chief, Keily and Redfern members. The Road River Group is divided into three new formations: the Ospika Formation, the Pesika Formation (formerly the Silurian Limestone) and the Kwadacha Formation (formerly the Silurian Siltstone). The Ospika Formation is further subdivided into five formal members: the Cloudmaker, Finlay Limestone, Chesterfield, Finbow Shale and Ware members.

The present study is mainly based on 17 samples containing more than 17 000 conodont elements from an approximately 14-m-thick succession of the Sholeshook Limestone Formation in a road cut near Whitland, South Wales, that yielded a diverse fauna of more than 40 taxa. It is dominated by representatives of Amorphognathus, Aphelognathus/Plectodina and Eocarniodus along with several coniform taxa. Representatives of Decoriconus, Istorinus and Sagittodontina are reported from the Ordovician of UK for the first time. The fauna is a typical representative of the British Province of the Atlantic Realm and includes a mixture of taxa of North American, Baltoscandic and Mediterranean affinities along with pandemic species. Based on the presence of many elements of Amorphognathus ordovicicus and some morphologically advanced specimens of Amorphognathus superbus, the Sholeshook Limestone Formation is referred to the lower A. ordovicicus Zone. Most of the unit is also coeval with Zone 2 of the Cautleyan Stage in the British regional stage classification, and stage slice Ka3 of the middle Katian Stage in the global stratigraphical classification, an age assignment consistent with data from trilobites, graptolites and chitinozoans. The unusually large collection of M elements of Amorphognathus provides insight into the complex morphological variation in this element of some Katian species of this genus. The Sholeshook conodont fauna is similar to those of the Crug and Birdshill limestones, but differs in several respects from the slightly older ones from the Caradocian type area in the Welsh Borderland. Although having some species in common, the Sholeshook conodont fauna clearly differs from coeval Baltoscandic faunas and is even more different in composition compared with equivalent North American Midcontinent faunas</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="123560072"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="123560072"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 123560072; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=123560072]").text(description); $(".js-view-count[data-work-id=123560072]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 123560072; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='123560072']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 123560072, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=123560072]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":123560072,"title":"Data from: Katian (Upper Ordovician) conodonts from Wales.

The stratigraphy of the Kechika Formation, Road River Group and Skoki Formation in northern British Columbia has been described previously during reconnaissance mapping. This study provides detailed stratigraphic descriptions of Upper Cambrian to Lower Silurian units from 9 key sections which span an east-west transect from the Macdonald Platform to the Kechika Trough, and 3 sections across the parautochthonous Cassiar Terrane. The transect lies within an interpreted upper plate of an asymmetrically rifted margin. Regionally, renewed phases of extension of the margin throughout the lower Paleozoic are recorded in abrupt lateral and vertical facies changes and pulses of volcanism. The tectono-stratigraphic framework was influenced by eustatic sea-level changes. Revised stratigraphic terminology proposed herein includes the division of the Kechika Formation into 5 formal members: the Lloyd George, Quentin, Grey Peak, Haworth and Mount Sheffield members. The Skoki Formation comprises three distinct, formal members defined as the Sikanni Chief, Keily and Redfern members. The Road River Group is divided into three new formations: the Ospika Formation, the Pesika Formation (formerly the Silurian Limestone) and the Kwadacha Formation (formerly the Silurian Siltstone). The Ospika Formation is further subdivided into five formal members: the Cloudmaker, Finlay Limestone, Chesterfield, Finbow Shale and Ware members.
