In regions where the saturation state of aragonite or calcite is greater than 1‚ the formation of shells and or skeletons is favored whereas for values less than 1.0‚ the seawater is corrosive to CaCO3 (John M. Pandolfi). This corrosive condition results in dissolution. Dissolution of the carbonate minerals calcite‚ aragonite‚ and high-Mg calcite is one of the driving forces for absorption of CO2 into the ocean. Because

ATMOSPHERE – OCEAN INTERACTIONS :: LECTURE NOTES 1. Introduction to the Atmosphere and Ocean J. S. Wright jswright@tsinghua.edu.cn 1.1 O VERVIEW This chapter outlines the main features of the atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude

There are a lot of plants in this world managed to grow in different kind of environments by adapting to those environments in certain ways. In this essay‚ plants grow in environment with different salinity are concerned. Plants can be divided into two different groups when it comes to salinity. The first type of plants is the plants that grow and reproduce in saline environment which are called halophytes (Jefferies. 1981). Whereas glycophytes are those plants growing in nonsaline soils (Jefferies

and shrubs that grow in saline coastal habitats in the tropics and subtropics – mainly between latitudes 25° N and 25° S. The saline conditions tolerated by various species range from brackish water‚ through pure seawater (30 to 40 ppt)‚ to water of over twice the salinity of ocean seawater‚ where the salt has become concentrated by evaporation (up to 90 ppt).[1][2] The many species of trees and shrubs adapted to saline conditions are not all closely related‚ and the term "mangrove" may be used for

High intertidal zone has rockpools and go to several months without being replenished from the seawater (McAllen & Taylor‚ 2001). Intertidal rockpool have a relative stable environment where that has few changes in terms of physical conditions when the water reaches low tide (Kemp‚ 2009).

desalination of water water‚ desalination of‚ process of removing soluble salts from water to render it suitable for drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long

Methods To determine the principals of osmoregulation‚ we sampled two lobsters from each tank and there were three different tanks which the water ranged in salinity. The experiment is to determine whether the six lobsters tested are osmoregulators or osmoconformers‚ this is done by obtaining a sample of hemolymph. The first step of the lab is to prepare the needle and syringe that will be taking the hemolymph. The syringe size was 1 ml‚ and the intention is to collect between 0.5 and 1.0 ml

Site suitability rating systems are to be used in assessing the environmental parameters of the sites. The biophysical parameters such as salinity‚ temperature‚ dissolved oxygen‚ pH‚ turbidity‚ water current and depth of the site are to be measured.
