Lake Guajará
Lake Guajará () is a lake of Marajó, which itself is an island in the mouth of the Amazon. It lies slightly to the north-east of Lake Arari. It is located in the state Pará in northern Brazil, on the border between the municipalities Salvaterra and Cachoeira do Arari. During the dry season, the waters of Lake Guajará are coloured bright green due to an abundance of phytoplankton and algae. There is an elevated mound called a ''teso'' next to the lake, which was visited by William Stebbins Barnard in 1870. Many local legends surround the lake, some of which were eternalised in the novel ''Marajó'' by Dalcídio Jurandir. They talk about an underground connection between Lake Guajará and the Atlantic Ocean The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about .

Marajó
Marajó () is a large coastal island in the state of Pará, Brazil. It is the main and largest of the islands in the Marajó Archipelago.

From approximately 400 BC to 1600 AD, Marajó was the site of an advanced pre-Cabraline society called the Marajoara culture, which may have numbered more than 100,000 people at its peak. Today, the island is known for its large water buffalo population, as well as the ''pororoca'' tidal bore periodically exhibited by high tides overcoming the usual complex hydrodynamic interactions in the surrounding rivers. It is the second-largest island in South America, and the 35th largest island in the world. With a land area of Marajó is comparable in size to Switzerland. Its maximum span is long and in perpendicular width. Geography ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Arari has an ellipsoid shape, oriented in the north-south direction. The lake can be considered the largest depression ob the island Marajó. Geological surveys identify it as the remainder of a much larger lake that existed in the past. The waters of the lake are generally muddy in the dry season. During the wet season, the area and depth of the lake change considerably because of intensive flooding of the surrounding areas. The waters become more clear and the lake is visited by boto dolphins, manatees and piracuru fish. Caimans, snakes and poraquê electric eels can also be found, as well as various types of birds, such as scarlet ibises and herons. The lake is fed in the north by the Jenipapucu River ...

Phytoplankton
Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater Aquatic ecosystem, ecosystems. The name comes from the Greek language, Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Phytoplankton obtain their energy through photosynthesis, as trees and other plants do on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers (euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations. Phytoplankton form the base of marine and freshwater food webs and are key players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthesis, photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, ''Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in embryophyte, land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a Division (taxonomy), division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a Polyphyly, polyphyletic group because they do not include a common ancestor, and although Eu ...

In 1870 he accompanied the scientific exploring expedition to Brazil as assistant geologist. On his return from Europe he lectured in 1874 at Cornell University, and during the summer at the school on Penikese Island. Since then he has lectured on natural history at Mississippi Agricultural College (1874–75); Illinois teachers' summer school (1875); Wisconsin State Normal School (1875); Oskaloosa College (1876–78); Cornell University (1878–1980); and Drake University (1886).
