The Role of Phytoplankton in Global Warming

ROLE OF THE SEA TO RESOLVE GLOBAL WARMING ISSUE

"The Role of Phytoplankton in Global Warming"

Global warming is one of the popular issues in human life at this time. The increase in annual average temperatures and rising sea levels are phenomenons that is proofing of the existence of global warming. At this time, a lot of solutions that try raised by the experts in addressing global warming continues.

One is with the help of the processes that have occurred at sea, such as the presence of phytoplankton in dealing with global warming.

One cause is identified as one cause of rising annual average temperature is the existence of carbon in the atmosphere. The existence of carbon causes the greenhouse effect that causes heat energy trapped in the atmosphere and are not able to bounce back out, causing rising temperatures. Therefore, the need for efforts in reducing the amount of carbon in the atmosphere, where one of them by increasing the number of the existing presence of phytoplankton in the ocean. As is known, the phytoplankton are living things that make the process of photosynthesis, and the process requires a carbon substance in the process. Therefore, the presence of phytoplankton then there will be conversion of carbon contained in the CO2 gas into a gas 02 that is the result of the process of photosynthesis.


Currently, there is need for the presence of phytoplankton inventory efforts in the wild. The goal is to predict the level of absorption of carbon by the phytoplankton. In addition, it can also be monitoring the presence of phytoplankton, phytoplankton growth can be monitored so that, if there is an increase or decrease the number. In this inventory effort needs to be balanced with conservation efforts and development of phytoplankton populations in the sea.

Spatial Modeling For Fire Forest Assessment


Indonesia is one country with very large forest holdings. As a country with an area of 93.92  million hectares of forest in 2005 (data from the Ministry of Forestry) will certainly be a lot of face many problems. One of the problems that arise on the sustainability of the existence of the forest  is the forest fire problem. Forest fires are a serious problem,because apart the reduced impact of forest area, another effect are such as pollution andenvironmental sustainability in the forest itself.

With the impacts, of course there is very important to monitor the local hotspots in the area of ​​forest in Indonesia. Not only that, with very large forests resulted in problems inmonitoring. One of the popular activities undertaken to monitoring in realtime, for example using  data from MODIS or  NOAA satellites. However, with the area so wouldrequires enormous resources.

Diagnostic Surface Horizons: The Epipedon


The epipedon (Gr. epi, over, upon, and pedon, soil) is ahorizon that forms at or near the surface and in which most ofthe rock structure has been destroyed. It is darkened by organic matter or shows evidence of eluviation, or both. Rock structure as used here and in other places in this taxonomy includes fine stratification (less than 5 mm) in unconsolidated sediments(eolian, alluvial, lacustrine, or marine) and saprolite derived from consolidated rocks in which the unweathered minerals and pseudomorphs of weathered minerals retain their relative positions to each other.
Any horizon may be at the surface of a truncated soil. The following section, however, is concerned with eight diagnostic horizons that have formed at or near the soil surface. These horizons can be covered by a surface mantle of new soil material. If the surface mantle has rock structure, the top of the epipedon is considered the soil surface unless the mantle meets the definition of buried soils in chapter 1. If the soil includes a buried soil, the epipedon, if any, is at the soil surface and the epipedon of the buried soil is considered a buried epipedon and is not considered in selecting taxa unless the keys specifically indicate buried horizons, such as those in Thapto-Histic subgroups. A soil with a mantle thick enough to have a buried soil has no epipedon if the soil has rock structure to the surface or has an Ap horizon less than 25 cm thick that is underlain by soil material with rock structure. The melanic epipedon (defined below) is unique among epipedons. It forms commonly in volcanic deposits and can receive fresh deposits of ash. Therefore, this horizon is permitted to have layers within and above the epipedon that are not part of the melanic epipedon.
