<p> The beach at Manzanillo, Costa Rica, is composed of a mixture of terrigenous siliciclastic and marine calcareous sediment. The most abundant siliclastic grains are magnetite and diopside. The most abundant calcareous grains are red algae and molluscan fragments. These grains are found in much greater abundance in the beach sediment then in their source areas as a result of their resistance to breakdown.</p> <p> The distribution of the siliclastic minerals on the beach shows longshore drift to be from east to west. The main source of siliclastic sediment is the Rio Sixaola. Local rivers provide small inputs of sediment.</p> <p> The trace element chemistry of the beach indicates the possibility that some elements may be absorbed on the surfaces of grains as opposed to being substituted for other elements in mineral lattices.</p> / Thesis / Bachelor of Science (BSc)

The purpose of this study was observing the Mealy Parrot (Amazona farinose virenticeps) in the open air nature, also the study found out their eating and nesting habits. Description of behavior in their natural environment and a description of the habitat in the study area. Monitoring, which took place at the census was made 3 weeks in September 2015. Other investigations in which observation was focused on finding nesting cavities and bird watching in the stream and this was performed three weeks in February 2016. Observation was carried out in Costa Rica on the southeast by the Caribbean Sea in the nature reserve Gandoca Manzanillo. Part of the observations was the liner census of Mealy Parrots with the use of the Passau methods to chart a path along the road leading from the village of Manzanillo to Puerto Vijejo. Length of the strip to the census was fixed at 2.1km about the width of 250m. At the counting was found out how Mealy Parrots was fed and what type of food. Also there was observe at what time Mealy Parrots swoop for food, and what trees were occupying them and in which part of tree crowns they were sitting in. Other research showed their behavior in the presence of other birds and other animals and how they were behaving in danger of predators. In another part of observing, that took place in February 2016 was searched two nests in tree hollows (Manilkara zapota) and (Pterocarpus officinalis). Only in one of the nesting cavity was found one egg, which was measured.

In terms of macroeconomic developments, the economic status in the Caribbean Region is largely driven by the global economy as well as developments in the US. Going forward, tourism is expected to remain as a key economic driver for the Caribbean region. Furthermore, the US is likely to continue to play a major influence. The bunkering industry in the Caribbean has been developing steadily for decades due to its popularity as a cruise ship destination and transshipments hub for east-west and north south cargo shipping routes. The enlargement of the Panama Canal is further expected to change competition dynamics between the region’s bunkering centers as a result of increase in shipping traffic and larger vessels. The shipping industry is the major demand driver for bunkering. It should be noted that both container liner and cruise sector as the two largest demand segments are concentrated. So in TL Blue Oceans LTD. our goals would be that our decision factors by ship operators with respect to bunkering operations and critical concerns can be summarized by 8 attributes: • 1 Bunker quality • 2 Market transparency (corruption free) • 3 Bunker price competitiveness • 4 Reliability and punctuality of bunker suppliers • 5 Bunkering facilities and services (adequacy and efficacy) • 6 Availability of all fuel grades including low-sulphur bunkers • 7 Location of port • 8 Government policies (e.g. quality control) and incentives
