GEOLOGICAL SOCIETY OF TRINIDAD & TOBAGO STRATIGRAPHIC WORKSHOPS 19 Dr. Hasley Vincent captures the ongoing discussions around this hot topic JUNE 2014 I 2 PRESIDENT’S CORNER Geo's, The GSTT had yet another successful and action packed quarter, this the second quarter of 2014. After reminiscing on the successful co-hosting of the first AAPG Geoscience Technology Workshop (GTW) Trinidad in March, we began the second quarter with a fun filled Family Day at Saline Bay in north eastern Trinidad. The Family Day kicked off with a beginners hike to Rio Seco Waterfall, observing the fauna, flora, and of course the rocks along the way. After a hearty curry lunch attendees relaxed in the afternoon, kayaking up and down the Saline River. Revitalized from that eco-adventure we turned our full attention to the Stratigraphic Renewal Project. The Stratigraphic Renewal Project was launched in 2013 with the primary goal of revising the current 16 year old Stratigraphic Chart of Trinidad & Tobago, publishing a new stratigraphic chart in 2017. During this second quarter of 2014, the GSTT hosted two Stratigraphic Renewal Workshops, the latter being held at San Fernando Hill. Presentations were sub- mitted from various companies such as BPTT, Range Resources, Centrica Energy and Petrotrin, as well as the latest research coming out of the Petroleum Geoscience Department at UWI. In late April, the GSTT launched its first circular and Call for Abstracts for our upcoming hosting of the 20th Caribbean Geological Conference. This conference returns to the shores of Trinidad & Tobago after some 20 years. This historic conference will run from the 17-22nd May, 2015 and will be held at the Hyatt Regency Hotel, Port-of-Spain. The Steering Committee will comprise of the 2013-2014 GSTT Board, the incoming 2014-2015 GSTT Board and a number of outstanding geologists, researchers and figures from around the Caribbean region such as Dr. James Pindell, Prof. John Weber, Prof. Leslie Wood, Prof Grenville Draper, Prof. Simon Mitchell, Prof. Ewald Poetisi, Prof. Paul Mann, Prof. Grant Wach, Dr. Chris Cornelius, Mrs. Deborah Pfeiffer, Mrs. Marny Daal, Mr. Curtis Archie, Dr. Hasley Vincent, Dr. Patricia Joseph and Mr. Philip Farfan. The 20th CGC poses to be the largest geological confer- ence of its kind to ever be held in Trinidad & Tobago. It is the GSTT’s intention to allow Geology and Geoscience students of UWI and UTT sponsored access to the entire conference. On 17th May, 2014, the GSTT ran its first ever field trip to the Paleocene-Eocene Soldado Rock. Led by our very own Dr. Hasley Vin- cent, attendees boarded two high powered pirogues from King’s Wharf, San Fernando and set sail trailing most of the western coastline of the southern peninsuela. Apart from the stunning Erin and Morne L’enfer outcrops along the route, attendees were treated to close up views to the docked Rowan Gorilla drilling rig, LNG tankers, and a traverse across the Soldado oilfield. Biostrat sampling was undertaken at Soldado rock for our very own Prof. Brent Wilson (UWI). Another first for this quarter, the GSTT ran its first joint webinar with the European Association of Geoscientists & Engineers (EAGE) at the Arthur Lok Jack Graduate School of Business. This talk featured the distinguished Dr. Satinder Chopra who discussed ‘Seismic attribute expression of differential compaction’. The GSTT is recognised as an Affiliated Society of the EAGE since 2012. Currently our very own Mr. Ariel Thomas (GSTT Director) is representing the GSTT at the EAGE 76th Conference & Exhibition, Amsterdam, where he is running the GSTT booth to promote awareness of the GSTT, and our upcoming Caribbean Geological Conference (CGC). Similarly, our Assistant Treasurer, Ms. Nicholette Camps is representing the GSTT and promoting the CGC at the 1st Suriname Inter- national Mining, Energy & Petroleum Conference and Exhibition, as part of the visiting Trinidad & Tobago Energy Chamber contin- gent. The quarter culminated with a packed Ichron sponsored Lunch & Learn Technical Session on ‘Maximising reservoir information from conventional cores’ followed by a Northern Range field trip led by our very own GSTT Treasurer Mr. Sisnarine Seegobin and UWI Phd. Candidate Ms. Anastasia Baboolal. So yet another busy quarter, setting new milestones for the GSTT. For our next quarter you can look forward to further Stratigraph- ic Renewal Workshops, GSTT Operations & Wellsite Geology Short Course, GSTT Fault Seal Analysis Short Course and of course, monthly Lunch & Learn Technical Sessions.

    FERN GAZ. 16(1, 2)11-122. 2000 11 CHECKLIST OF THE PTERIDOPHYTES OF TRINIDAD & TOBAGO Y. S. BAKSH-COMEAU The National Herbarium of Trinidad and Tobago. Department of Life Sciences, The University of the West Indies, St. Augustine, Trinidad, West Indies Key words: checklist, Trinidad and Tobago pteridophytes, types, habitat, distribution. ABSTRACT Three hundred and two species and eight varieties or subspecies in 27 families and 77 genera of ferns and fern allies are listed. Four new combinations and states are made, and one synonym lectotypified. A serious attempt has been made to establish types; selections of specimens studied are cited. INTRODUCTION Recent studies of ferns in Trinidad and Tobago (Baksh-Comeau, 1996, 1999) have combined a review of the pteridophyte collection at The National Herbarium of Trinidad & Tobago with field surveys undertaken to assess the community status of these plants on both islands. This checklist has been developed as an integral part of those studies, but it is also an essential prerequisite to ongoing research covering a reclassification of the vegetation of the islands and to the preparation of a comprehensive vascular plant flora. The herbarium count and field survey revealed 251 species confirmed by voucher specimens housed in Trinidad. Additional species have been attributed to Trinidad or Tobago in early publications for Trinidad and in Floras and monographs for neighbouring areas. The number of species now believed to be indigenous in these islands is 282. Cultivated species that have escaped, and introductions which have become naturalized number 20. Early reports include Grisebach (1859-64) who listed 106 species; Eaton (1878) approximately 78 of the 150 or so species eventually collected by August Fendler; Jenman (1887) had about 184 species; Anon (1889) listed 206 binomials including a few introduced taxa; Jenman (1898-1909), in an incomplete coverage of the fern flora, described 140 taxa of which 10 were new species; Hart (1908), including some cultivated plants, listed 283 binomials of pteridophytes.

  • A New Frontier for Caribbean Conv Ier for Caribbean Convergence
    Caribbean Journal of International Relations & Diplomacy Vol. 1, No. 2, June 2013: pp.5-20 ORIGINAL RESEARCH ARTICLE A New Frontier for Caribbean Convergence Winston Dookeran Ministry of Foreign Affairs, Trinidad & Tobago Abstract : This article elaborates, explains and analyses the notion of Caribbean Convergence. This represents a new way of thinking about integration in the region, and a potential strategy for injecting the process with new life and ene rgy. The article provides a twelve -point action program for Caribbean convergence , which is grounded in a distinctive series of strategies relating to finance, resource clustering, infrastructure, and production integration . Keywords : Caribbean Integration, Regionalism, Convergence, CARICOM This article is about Caribbean development and the integration movement in the light of the new political economy aagendagenda for the future identified in 2008 calling for ‘fresh thinking’. 1 The document presents the framework for a new political and economic life to the process of Caribbean integration. The initiative is not to supplant the Caribbean integration movement, but to add on ttoo it with some innovative ways of moving the process forward that is understo od as ‘Caribbean convergence’ to create an ‘Economy of tthehe Caribbean Sea’. The idea of Caribbean convergence has already been pputut forth and discussed on various occasions over the last coupcouplele of years with positive feedbacks. These feedbacks have provideprovidedd the inputs for the framework developed here which is an innovative approach to revive CARICOM in a different context to make it more relevant to capture on ‘A New Frontier of Caribbean Convergence’. 6 Winston Dookeran Some concerns recently raised by ECLAC were the mechanisms of convergence and the modalities to engage the private sector in CARICOM.

  • Good Liming in Trinidad: the Art of Doing
    Liminalities: A Journal of Performance Studies Vol. 12, No. 4 (2016) Good Liming in Trinidad: The Art of Doing Something Carmen L. McClish Trinidad and Tobago is a playful culture where locals proudly “lime” often and with great zealousness. This essay describes the elements of liming to further un- derstanding of how and why these events are centered in play. I contend that lim- ing is an activity engaged in by all Trinidadians—men, women and children, from all socio-economic classes, and that it involves both public and private spac- es. These spaces include street corners, beaches, clubs, and private homes. Alt- hough liming has been defined as “idling,” this does not adequately explain these events that often involve at least a few of the following: eating, drinking, dancing, storytelling, and just general merrymaking. What is valued is the ordinary be- coming extraordinary. I posit that liming is play in both the activity and the at- titude based in a mindset of living in the present and practicing one’s freedom. I arrived in Trinidad in August of 2011, I had never been to the Caribbean be- fore, and was immediately hit with the wall of humidity. Soon after with the many stares as “whites” in Trinidad and Tobago are a minority group. I was greeted in Creole, a newfound Trinidadian friend commenting that I “reach,” or arrive. Many things struck me about Trinidad initially but what I knew quickly was that Trinidadians are friendly and gregarious people and that the culture is generally laid back. Although these initial reactions still held true, even after three years in Trinidad, both the culture and the people showed themselves to be more complicated.

Contact the Lincoln Institute with questions or requests for permission to reprint this paper. [email protected] Lincoln Institute Product Code: WP13TB1 Abstract The Caribbean and northern coastal Brazil face severe impacts from climate change, particularly from sea-level rise. This paper analyses current land use and development policies in three Caribbean locations and one at the mouth of the Amazon River to determine if these policies are sufficient to protect economic, natural, and population resources based on current projections of urbanization and sea-level rise. Where policies are not deemed sufficient, the authors will address the question of how land use and infrastructure policies could be adjusted to most cost- effectively mitigate the negative impacts of climate change on the economies and urban populations.

    157 The Black Power Movement in Trinidad and Tobago Jerome Teelucksingh ABSTRACT The article examines the impact of Black Power in Trinidad and Tobago during the 1960s and 1970s. Black Power appealed to a wide cross-section of the public, including academics, trade unionists, and the underprivileged. There is emphasis on the global and regional linkages, including the Sir George Williams Affair in Canada and the Black Power Movement in the United States. Furthermore, Black Power participants in Trinidad and Tobago maintained contacts with their counterparts in other Caribbean countries. The article also provides evidence that the Black Power Movement highlighted the economic problems, racism, and social crisis facing Trinidad and Tobago. This included removal of restrictions from certain jobs and reduction of the racial tension between Afro-Trinidadians and Indo-Trinidadians. Mention is made of individuals and groups who provided leadership, guidance, and ideological input within the movement. Origins of Black Power Black Power in Trinidad and Tobago, during the 1960s and 1970s, was strongly influenced by the ideology of Pan-Africanism, which emerged during the nineteenth century and continued into the early twentieth century when Marcus Garvey, a Jamaican based in the United Black Diaspora Review 4(1) Winter 2014 158 States, promoted race consciousness during the 1920s and 1930s.1 Race consciousness, African identity, and pride were important components of Pan-Africanism and Garveyism, which comprised the foundation of Black Power. The emergence of Black Power during the 1960s signified a struggle to reclaim authority, power, identity, and respect. Black Power in the United States was a response to many years of racism faced by African Americans and that turbulent era was marked by discontent with the “establishment” and rejection of conventional politics.

  • General Debate Trinidad and Tobago National Statement 75Th Session of the United Nations General Assembly Delivered by Dr
    General Debate Trinidad and Tobago National Statement 75th Session of the United Nations General Assembly Delivered by Dr. the Honourable Keith C. Rowley Prime Minister Mr. President, It is an honour to address this august Assembly of States, on this milestone, the 75th Session of the United Nations General Assembly. Allow me at the outset, to extend congratulations to you, Mr. President, on behalf of the Government and People of the Republic of Trinidad and Tobago, on your election as President for this Session. You have the full support of Trinidad and Tobago, as we acknowledge the enormity of your undertaking, especially as we continue to grapple with a global pandemic which has affected us all. I also wish to express our deepest gratitude to your predecessor, His Excellency Professor Tijani Muhammad Bande for his astute leadership in the 74th session and for successfully guiding the work of the session during the challenging onset of the 2019 Novel Coronavirus pandemic. 1 Mr. President, Seventy-five years ago, in the aftermath of the Second World War, the United Nations was created, with the primary objective of saving “succeeding generations from the scourge of war, which had twice in our lifetime brought untold sorrow to mankind.” Undoubtedly, the desire to create the political, social and economic conditions for lasting peace remains as fervent today as it was during the organisation’s genesis in San Francisco. The 75th anniversary of the United Nations presents an ideal opportunity for reflection and introspection on whether we have embraced the opportunities to re-engineer and reinvigorate the mechanisms of multilateralism, to engender the peace, which has so far remained elusive, to advance social progress and to chart the way forward to attain sustainable development, which would benefit all of humanity.

  • Microtityus Rickyi (Dwarf Scorpion)
    UWI The Online Guide to the Animals of Trinidad and Tobago Diversity Microtityus rickyi (Dwarf Scorpion) Order: Scorpiones (Scorpions) Class: Arachnida (Spiders, Scorpions and Mites) Phylum: Arthropoda (Arthropods) Fig. 1. Dwarf scorpion, Microtityus rickyi. [www.ntnu.no/ub/scorpion-files/m_rickyi2.jpg, downloaded 23 October 2016] TRAITS. Microtityus rickyi are the smallest scorpions of the Western Hemisphere with an average size of 19mm. A light yellow pigmentation with black to light brown spots is found throughout the carapace (anterior plate that covers the head and thorax) and opisthosoma (segmented mid-body and tail). Its stinger is dark brown. The almost triangular carapace with a distinctly notched margin is characteristic of Microtiyus rickyi (Fig. 1). Sexual dimorphism is exhibited in regards to their size; the largest females are 18.6mm and males 16.6mm (Kjellesvig- Waering, 1966) DISTRIBUTION. Microtityus rickyi are endemic to Trinidad and Tobago, found nowhere else, and rather rare, comprising less than 1% of the scorpion population sampled (Kjellesvig- UWI The Online Guide to the Animals of Trinidad and Tobago Diversity Waering, 1966). Microtityus rickyi can be found at Lady Chancellor Hill, Mt. St. Benedict, Chacachacare Island, Gaspar Grande Island (Fig. 2), and Speyside Tobago (Prendini, 2001). HABITAT AND ACTIVITY. Microtityus rickyi are predominantly found hanging motionless on the underside of rocks within forests, on exposed soil banks or leaf litter though some have been found near the coast and on hills at heights of 200m. They can also be considered as semi- arboreal as some have been found a few metres up tree trunks (Prendini, 2001). FOOD AND FEEDING.

  • The Cretaceous Source Rocks from East Venezuela – Trinidad-Guyana/Suriname Basins, NE South America
    The Cretaceous source rocks from East Venezuela – Trinidad-Guyana/Suriname basins, NE South America Francia A. Galea Alvarez, PhD Actus Veritas Geoscience, LLC 1st HGS/EAGE Conference on Latin America: South American Petroleum Play for Future Decades of the Third Millennium. Houston, November 19 – 20, 2019 Abstract The Cretaceous source rocks from East Venezuela - Trinidad - Guyana/Suriname basins, NE South America Galea Alvarez, Francia A. – Actus Veritas Geoscience, LLC The major contribution to the oil fields in East Venezuela and Trinidad are Cretaceous source rocks, Late Albian – Santonian in age. The Querecual Formation, from the Guayuta Group, is the source rock of the oil and gas from the giant and super giant oil fields like Carito, Furrial_Musipan, Quiriquire, Great Oficina, Anaco Trend, and Santa Barbara oil fields, among others. The Orinoco Belt huge deposits of oil are aromatic-asphaltic oils biodegraded interpreted as originated in organic rich carbonate sediments, with some components of siliciclastic, deposited in an anoxic environment as the one described for the Querecual Formation at the type section and outcrops around the Pozuelos Bay, northern Anzoátegui state, southwest of the Cariaco Basin. Studies at the type section of the Querecual Formation described black shales, limestones and marls, rich in foraminifers and other macrofossils, which were used to identify biostratigraphic zones from late Albian to Santonian, and a hiatus at the early Cenomanian. Paleowater depths were interpreted as middle to upper bathyal (based on microfossils content). Mainly microlaminated foraminiferal microfacies were linked to anoxic-dysoxic levels. Total carbon (TC), Total organic Carbon (TOC), inorganic carbon (Cinorg), and total Sulfur (tS), and the calcium carbonate concentration (CaCO3) were measured and interpreted: high values of CaCO3, of the TOC and planktonic foraminifers decreases from base to top, and were identified in strata from late Cenomanian, late Turonian, Coniacian and Santonian.

  • Trinidad and Tobago: Venezuelan Refugees at Risk
    First UA: 126/20 AMR 49/2953/2020 Trinidad and Tobago Date: 13 August 2020 URGENT ACTION VENEZUELAN REFUGEES AT RISK At least 165 Venezuelans have been deported by Trinidad and Tobago in recent weeks. Pushing a xenophobic narrative targeting Venezuelans and associating them with COVID-19, the government announced it will deport Venezuelans who have “entered illegally” and those with legal residency found to be helping them. This fuels a climate of fear which risks pushing people underground and away from health services. We are calling on Trinidad and Tobago to refrain from deporting people in search of protection and to work with partners to find human rights-based solutions for them. TAKE ACTION: WRITE AN APPEAL IN YOUR OWN WORDS OR USE THIS MODEL LETTER The Honourable Dr Keith Rowley Prime Minister of Trinidad and Tobago 13-15 St Clair Avenue Port of Spain, Trinidad and Tobago Phone number: +1 (868) 622-1625 Emails: [email protected]; [email protected]; Dear Prime Minister, I write to you with deep concern over reports that at least 165 Venezuelans were deported from Trinidad and Tobago to their country in recent weeks. Trinidad and Tobago must guarantee and protect the rights of refugees and people seeking international protection. Millions of Venezuelans are fleeing an unprecedented human rights crisis in their country. They need a life jacket, not to be sent back to a country where they may face torture or other grave human rights violations. Instead, Venezuelan refugees and those who support them are targeted by xenophobic narratives and accusations of increasing the risks of COVID-19 for Trinidad and Tobago people, justifying procedures of deportation without properly assess the danger that those returned may face in Venezuela.
