By Abhijit Mitra, Sufia Zaman

The ever expanding emission of carbon dioxide as a result of speedy industrialization, urbanization, unplanned tourism and alteration of land use trend is inflicting extraordinary alterations to marine biodiversity. regardless of political philosophy, country, caste, intercourse and faith, mankind is below the appalling shadow of weather switch. this day nature-based techniques for the mitigation of weather swap are more and more approved as a part of the reasonably cheap resolution. Thrust has been given through numerous clinical groups to evaluate the importance and viability of carbon sequestering power of crops. Coastal manufacturer groups like mangroves, salt marsh grass, seagrass beds, and seaweeds take in atmospheric carbon dioxide through the means of photosynthesis. This carbon referred to as the ‘blue carbon’ is therefore linked to the marine and estuarine ecosystems. even though, a couple of gaps in our medical wisdom on blue carbon area nonetheless exist. Molluscs, coral reefs, phytoplankton, that are among the $64000 storehouses of carbon, haven't been addressed. only a few medical reports at the carbon kept in those necessary traditional vaults were played, and no information financial institution is offered on their carbon sequestering means on worldwide foundation. The methodologies for assessing blue carbon inventory additionally desire additional standardization in order that credits from blue carbon reservoir is approved via the overseas our bodies within the type of a concrete coverage. it's a subject of serious appreciation that Conservation overseas (CI), the foreign Union for Conservation of average assets (IUCN), and the Intergovernmental Oceanic fee (IOC) of UNESCO is taking part with governments, learn associations, non-governmental and overseas corporations, and groups around the globe to increase administration techniques, monetary incentives and coverage mechanisms for making sure conservation and recovery of blue carbon ecosystems and enforce tasks world wide that display the feasibility of blue carbon accounting, administration, and incentive agreements. the current e-book has severely offered the information financial institution for every group of blue carbon now not basically within the kind of textual content description, but in addition via case reviews which are the results of study tasks and pilot programmes.

Gradually with the passage of time, several factors, such as energy from space and the decay of radioactive elements, contributed to raising its temperature. The process of heating continued for several hundred million years until the temperature at the centre of the earth was high enough to melt iron and nickel. 8 Comparative account of the major ocean Ocean Atlantic Pacific Indian Surface area (km2) 82,400,000 165,200,000 73,400,000 the earth’s core, displacing lighter, less dense elements and eventually raising the core temperature to approximately 2,000 °C.

7 Common brackishwater phytoplankton with unique shape and configuration planktonic through out the life cycle are as follows: (1) diatoms, (2) dinoflagellates, (3) coccolithophores, (4) selective species of blue-green algae and (5) some species of green algae. The members of phytoplankton community have unique size, shape and morphological features (Fig. 7). Diatoms These floating plants are all microscopic in size and are characterized by the presence of shell or frustule. The shell or frustule is composed of translucent silica.

In other words, phytoplankton respond very rapidly to changes in their environment. 2 Biodiversity of the Blue Zone Phytoplankton sometimes may cause adverse impact on the marine and estuarine environment. ) and kelp. Furthermore, when the phytoplankton eventually die back and break down, an excessive amount of oxygen is required to fuel this process, and hence, areas may become deprived of oxygen. Excessive nutrients, and/or changes in their relative concentrations, may be one factor in a chain of events leading to changes in the species composition of the phytoplankton communities.
