• Venezuela and the Caribbean: The areas marked in yellow show high temperatures. Those marked in green, and which stretch the entire length of Venezuela's Caribbean coast, enjoy lower temperatures. In the Orinoco Delta region, the temperatures are always high. This photograph is for the months of February or March, when the upwelling current phenomenon causes low temperatures next to the coast. The Gulf of Mexico and the eastern costs of the United States, included Florida, also experience low temperatures. In the high-temperature months, temperatures are uniform throughout the Caribbean and the Gulf of Mexico and along the eastern coasts of the United States.
• The biological productivity of Venezuela's coasts: Between January and April, high biological productivity is found in the northeastern region, as a result of the upwelling currents phenomenon caused by the constancy and intensity of the trade winds. The same phenomenon occurs in the Gulf of Venezuela and around the La Guajira Peninsula. The areas colored in greens and blues show the concentration of chlorophyllous pigments (high productivity). In October, high productivity (high density of chlorophyllous pigments in the phytoplankton) is found in the estuary of the Orinoco River and extends across the Caribbean Sea almost as far as Puerto Rico. This occurs because the sediments brought down by the Orinoco River are full of inorganic nutrients (nitrates, phosphates, etc.), which enrich the waters like fertilizer.
• In the center of the exhibition hall is a collection of corals from the islands of Cubagua and Los Roques.
