long-standing mystery concerning barren waters in the Antarctic‚ subarctic‚ and equatorial Pacific Oceans. With the abundant concentrations of nutritious nitrate and phosphorus in all three regions‚ phytoplankton should thrive. But it doesn’t. Martin became convinced in the late 1980s that lack of iron keeps the phytoplankton from making use of the nutrients and that a little extra iron would trigger rapid growth of the plants. He calculated that it would be feasible to fertilize the ocean on a massive scale

threat to the marine life. Microscopic marine organism such as phytoplankton and zooplankton are highly sensitive to UVB radiation (1). Phytoplankton are single-celled organism‚ as UVB is absorbed by a few layer of cells‚ single celled organisms like phytoplankton lack out layers protection from the radiation (4‚9). Even a small increase in UVB radiation is deleterious to them‚ so excessive UVB impairs the photosynthesis of phytoplankton‚ inhibits its growth rate and cause lethal DNA damage to it‚

microscope in order to identify E. coli‚ filaments and phytoplankton for further analysis. A total of 5.72 x 106 E. coli bacteria were determined of the microscopy filter giving the first point on a growth curve. The growth curve suggests the bacteria entering their stationary growth phase with a flattening curve. Water from two sewage treatment plants‚ Vik and Grødaland was analysed‚ with Grødaland water containing a large amount of filaments. Phytoplankton diversity was compared between Stokkavannet andHålandsvannet

the idea is to dump iron into the ocean to allow phytoplankton to thrive. These phytoplankton absorb carbon dioxide and along with other nutrients and can possibly‚ as it dies‚ make its way down to the ocean floors. Essentially the goal is to feed these phytoplankton and have them drag carbon dioxide down with them to the ocean floors keeping them there for about 100 years until the natural ocean cycles would eventually surface these phytoplankton. I am all for finding different ways to help fight

ABSTRACT The different phytoplankton species contains amino acids‚ carbohydrates‚ nutrients‚ fatty acids‚ vitamins‚ enzymes and minerals. In which Indian White Shrimp (Penaeus indicus) requires lipids‚ amino acids‚ carbohydrates as energy source‚ vitamins and minerals for their growth and survival. This study was conducted to test the survival and growth of Indian White Shrimp (Penaeus indicus) larvae using the different phytoplankton species as natural diet. 300 nauplii were placed on

parameter due to its indirect effects‚ including the protection of aquatic organisms from major changes in pH. In low alkalinity waters‚ where CO2 and dissolved carbonates are at low concentrations‚ photosynthesis may be inhibited‚ thus restricting phytoplankton growth. Levels above 175 mg CaCO3/L reduces natural food production in ponds which‚ in turn‚ leads to a decrease in optimal production. Salt water is slightly alkaline and has a strong buffering capacity so alkalinity is not usually of concern

Seas and oceans provide various types of resources to human beings and habitats to numerous species of plants and animals. They play very important roles in the economy of a nation and its people. Still‚ the marine and coastal ecosystems are under severe stress due to human activities. Ocean Resources The ocean is one of Earth ’s most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It ’s used for transportation—both travel

The Potential Effects of a Depleted Ozone Layer - Detrykowski "And God said‚ let there be light and there was light and then God saw the light‚ that it was good " ( Genesis 1: 3-4 ). Undoubtedly‚ light is good. Without light man could not survive. Light is the ultimate cosmic force in this universe allowing man to progress and flourish. In the form of heat‚ light from the sun warms the Earth. Light‚ also‚ is the single most important factor influencing the growth and development of plants
