The Institute of Marine Affairs Species Checklist Data is derived from its historical manuscripts which examined species distribution in Trinidad & Tobago during the years 1985-2007.

Data Records

The data in this checklist resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 431 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Taxon (core)

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.


The table below shows only published versions of the resource that are publicly accessible.

Geographic Coverage

The waters surrounding the Caribbean Islands where biodiversity information was collected by members of the Institute of Marine Affairs.

Bounding Coordinates South West [9.189, -84.99], North East [25.562, -55.195]

Taxonomic Coverage

This datasets consists of biodiversity data derived from six different scientific manuscripts produced by Researchers at the Institute of Marine Affairs. The research projects associated with these manuscripts covered a wide array of marine species including, but not limited to, Sponges of Class Demospongiae from Trinidad and Tobago; Octocorals from Trinidad and Tobago; and ahermatypic shallow-water corals of Trinidad. There is also marine biodiversity data derived from ecological surveys done around the reefs of Tobago.

Class Demospongiae (Sponges), Anthozoa, Ulvophyceae, Phaeophyceae, Florideophyceae, Compsopogonophyceae, Hydrozoa, Hexanauplia, Polychaeta, Malacostraca, Gastropoda, Crinoidea, Ophiuroidea, Echinoidea, Actinopterygii

Project Data

This data is a part of the Institute of Marine Affairs' (IMA's) aim of developing a centralised Marine Biodiversity Hub (MBH) for the purpose of (1) effective dissemination of data on the state of marine ecosystems in T&T to research partners, civil society, decision- makers and the international community, and (2) building capacity for more integrative research collaborations and creating sustainable partnerships through data sharing for research, management and conservation.

Title Marine Biodiversity Hub
Identifier BID-CA2020-004-INS
Funding The IMA has received an Institution-level biodiversity data mobilization grant from the Global Biodiversity Information Facility's (GBIF's) Biodiversity Information for Development (BID) programme- funded by the European Union- to develop a centralised Marine Biodiversity Hub (MBH).
Study Area Description The study area of research at the Institute of Marine Affairs (IMA) is mainly focused in the waters of the Trinidad and Tobago Economic Exclusion Zone (TT EEZ) with some past projects covering marine species in Venezuela, St. Lucia, St. Vincent and the Grenadines, and Grenada. Marine biodiversity data has been collected by the IMA since 1978 and the volume of data collected continues to grow each year. The studies done cover a wide array of taxonomic coverage including but not limited to corals, fish, sponges, macroalgae and polychaetes.
Design Description As the primary government agency focused on researching and monitoring marine biodiversity over the last 40 years, the IMA holds the largest repository of marine biodiversity data in the country. The data that is available is in a myriad of forms and not centralised or searchable. As a result, it is not readily accessible to IMA researchers, government agencies, academia, or the public. This limits research activities, informing of policy, and civil society activities undertaken to reduce the negative impacts of human activities on marine biodiversity. This project aims to do the following: (1) resolve the absence of a standard protocol for responsible data management (2) improve the efficiency of data management and dissemination e.g. national assessments (such as State of the Marine Environment reports), regional assessments (such as the Cartagena Convention’s State of the Convention Area Report) and international reporting (such as for the Sustainable Development Goals and United Nations Convention on Biological Diversity targets), (3) encourage integrative research to support government policy and decision making, (4) improve the accessibility of data to the general public (TTBIS/ GBIF). The marine data mobilized through GBIF will fill important knowledge gaps on the biodiversity of marine life, and highlight the many marine ecosystems present in T&T. The data will add to regional and global assessments of marine biodiversity. This should assist with bringing international awareness on the state of marine biodiversity in T&T, and lead to potential conservation and research projects. The data sources for the MBH will include literature citations for scientific reports which discuss marine biodiversity but no longer have the raw data available for them as well as ongoing monitoring data from institutional projects such as coral reef health monitoring. Dependent on the metadata available, the scientific reports will be categorized into checklist, occurrence and event sheets. Past available biodiversity data at the Institute has been digitized and are undergoing the standardization process to adhere to the Darwin Core principles.

Sampling Methods

This data was derived using past scientific reports published by the Institute of Marine Affairs through its relevant researchers. The data was collected by the researchers by way of ecological surveys through snorkel and S.C.U.B.A.

Study Extent The study area for this data was focused on the waters in the Trinidad and Tobago Economic Exclusion Zone (TT EEZ).
Quality Control The derived biodiversity data was cross checked using the Global Biodiversity Information Facility's Species Name Matching Tool to ensure that the scientific names used were the globally accepted names.

Method step description:

  1. The checklist data was derived from past scientific reports published by the Institute's researchers. The marine biodiversity data was derived from the manuscripts and then cross-checked using the Global Biodiversity Information Facility's Species Name Matching Tool to ensure that the scientific names used were up-to-date.
