The 150 Books of Influence Project Committee recognizes the support of the Province of Nova Scotia. We are pleased to work in partnership with the Department of Communities, Culture and Heritage to develop and promote our cultural resources for all Nova Scotians. Final publication date November 2017. Books are our finest calling card to the world. The stories they share travel far and wide, and contribute greatly to our global presence. Books have the power to profoundly express the complex and rich cultural life that makes Nova Scotia a place people want to visit, live, work and play. This year, the 150th Anniversary of Confederation provided Public Libraries across the province with a unique opportunity to involve Nova Scotians in a celebration of our literary heritage. The value of public engagement in the 150 Books of Influence project is demonstrated by the astonishing breadth and quality of titles listed within. The booklist showcases the diversity and creativity of authors, both past and present, who have called Nova Scotia home.

In chemical composition the intrusion is highly evolved but probably of continental tholeiitic affinity. It differs from other mafic igneous Maritime Sediments Editorial Board rocks of southern Nova Scotia, but on the basis of geographic location, mineralogy, and chemistry is considered to be related to the volcanic rocks of ISSN the White Rock Formation in the Cape St. Mary's — Yarmouth area.

Project Team Jason Googoo, Project Manager Dave Moore, Author and Research Craig Hodder, Author and GIS Technician Katy McEwan, MEKS Interviewer Mary Ellen Googoo, MEKS Interviewer John Sylliboy, MEKS Traditionalist Prepared by: Reviewed by: ___________________ ____________________ Craig Hodder, Author Jason Googoo, Manager Green Cove MEKS Executive Summary This Mi’kmaq Ecological Knowledge Study, also commonly referred to as an MEKS or a Traditional Ecological Knowledge Study (TEKS), was developed by Membertou Geomatics Solutions (MGS) for Parks Canada for the proposed Never Forgotten National Memorial Complex (NFNMC) Project. This MEKS mandate is to consider land and water areas which the proposed project will utilize, and to identify what Mi’kmaq traditional use activities have occurred, or are currently occurring within, and what Mi’kmaq ecological knowledge presently exists in regards to the area. In order to ensure accountability and ethic responsibility of this MEKS, the MEKS development has adhered to the “Mi’kmaq Ecological Knowledge Protocol”. This protocol is a document that has been established by the Assembly of Nova Scotia Mi’kmaq Chiefs, which speaks to the process, procedures and results that are expected of a MEKS. The Mi’kmaq Ecological Knowledge Study consisted of two major components: • Mi’kmaq Traditional Land and Resource Use Activities , both past and present, • A Mi’kmaq Significance Species Analysis , considering the resources that are important to Mi’kmaq use. The Mi’kmaq Traditional Land and Resource Use Activities component utilized interviews as the key source of information regarding Mi’kmaq use in the Project Site and Study Area.

  • Petrology of the Shelburne and Barrington Passage Plutons Southern Nova Scotia
    PETROLOGY OF THE SHELBURNE AND BARRINGTON PASSAGE PLUTONS SOUTHERN NOVA SCOTIA H. Dean Rogers and Sandra M. B a r r Department of Geology, Acadia University Wolfville, Nova Scotia BOP 1X0 Date Received December 3, 1987 Date Accepted February 25, 1988 The Shelburne and Barrington Passage plutons are adjacent, but contrasting, intrusions located on the southern coast of Nova Scotia. The Shelburne Pluton consists mainly of monzogranite and granodiorite, with minor areas of tonalite, whereas the Barrington Passage Pluton consists of tonalite gradational to quartz diorite. Both plutons have petrochemical characteristics consistent with derivation from metasedimentary source rocks. Major and trace element trends within the Barrington Passage tonalite suggest that magma evolution was controlled by biotite fractionation, whereas plagioclase and biotite fractionation may have produced much of the variation within the Shelburne Pluton. Tonalite within the Shelburne Pluton has higher Sr than the Barrington Passage tonalite, and may have formed by plagioclase accumulation from co-magmatic granodiorite and monzogranite of the Shelburne Pluton. On the basis of previously published Ar data, the Barrington Passage Pluton was probably emplaced during the main phase of regional metamorphism related to the Acadian Orogeny (about 400 Ma). A Rb-Sr whole-rock isochron suggests an age of 466 + 17 Ma for the Shelburne Pluton, although published Ar data have indicated a Devonian age. The ages of these plutons and others in the southernmost Meguraa Terrane must be better constrained before a reliable assessment of petrogenesis and tectonic history can be made. Les plutons de Shelburne et Barrington Passage sont des intrusions adjacentes qui contrastent et sont situAes sur la cote mAridionale de la Nouvelle-Ecosse.

  • Supposed Periodicity of Redpoll, Carduelis Sp., Winter Visitations in Atlantic Canada
    Supposed Periodicity of Redpoll, Carduelis sp., Winter Visitations in Atlantic Canada ANTHONY J. E RSKINE 1 and REID MCMANUS , J R.2 116 Richardson Street, Sackville, New Brunswick E4L 4H6 Canada 2657 Royal Road, Memramcook, New Brunswick E4K 1X1 Canada Erskine, Anthony J., and Reid McManus, Jr. 2003. Supposed periodicity of Redpoll, Carduelis sp., visitations in Atlantic Canada. Canadian Field-Naturalist 117(4): 611-620. Redpoll (primarily Carduelis flammea ) data from the New Brunswick–Nova Scotia border region were reviewed in the context of alleged biennial periodicity of irruptions south of their breeding range. Long-term records by the authors suggested a number of departures from visitation in alternate years. Three local Christmas Bird Counts (CBCs) spanning the last 41 winters supported the less-than-regular pattern shown by individual observations. CBC redpoll data from across the Atlantic Provinces revealed annual redpoll visitations across southern New Brunswick, where the largest regional counts (adjusted for observer effort) usually occurred. Visitation to Prince Edward Island, Nova Scotia, and Newfoundland was less frequent, and patterns there were often obscured by scarcity of CBCs with both long-run coverage and redpolls. Examination of those data in relation to varying food availability suggested that irregular abundance but near-annual occurrence of redpoll visitation explains observed observations better than attempts to find periodicity in their irruptions. Key Words: Common Redpoll, Carduelis flammea , Atlantic Provinces, winter, irruptions, periodicity, food availability. Redpolls (here discussed as Carduelis flammea; C. and limited seasonal sampling by CBCs. Hochachka hornemanni is rare – and under-detected – in our et al.

  • Groundwater Resources and Hydrogeology of the Windsor-Hantsport-Walton Area, Nova Scotia
    PROVINCE OF NOVA SCOTIA DEPARTMENT OF MINES Groundwater Section Report 69- 2 GROUNDWATER RESOURCES AND HYDROGEOLOGY of the W I NDSOR- HANTSPORT- WALTON AREA, NOVA SCOTIA by Peter C. Trescott HON. PERCY GAUM J.P. NOWLAN, Ph.D. MINISTER DEPUTY MI NI STE R Halifax, Nova Scotia 1969 PREFACE The Nova Scotia Department of Mines initiated in 1964 an extensive program to evaluate the groundwater resources of the Province of Nova Scotia. This report on the hydrogeology of the Windsor- Hantsport-Walton area is an ex- tension of the Annapolis-C o r n w a I I i s Val ley study reported in Department of Mines Memoir 6. The field work for this study was carried out during the summer of 1968 by the Groundwater Section, Nova Scotia Department of Mines, and is a joint undertaking between the Canada Department of Forestry and Rural Development and the Province of Nova Scotia (ARDA project No. 22042). Recently the ad- ministration of the A R D A Act was t r a n s f e rr e d to the Canada Department of Regional Economic Expansion. It should be pointed out that many individuals and other government agencies cooperated in supplying much valuable i n f o rma t i on and assistance throughout the period of study. To list a few: Dr. J. D. Wright, Director, Geological Division and the staff of the Mineral Resources Section, Nova Scotia Department of Mines, Mr. J. D. McGinn, Clerk and Treasurer, Town of Hants- port, and the Nova Scotia Agricultural College at Truro.
