Understanding the Chemical Factors of Water in Aquaculture Chemical factors of water. Various chemicals present in water, the acidity and alkalinity of water, salinity, pH levels and dissolved substances can influence chemical reactions in water and can affect your productivity. Below are a few chemical factors that affect your freshwater fish farm.

- ocean surface temperatures are part of the forcing for the atmosphere, changes in high-latitude salinity distribution can be involved in climate change. In addition to its effect on seawater density, salinity is useful in itself as a tracer of ocean circulation and mixing. Salinity is established in the ocean’s surface layer by local processes, and therefore salinity variations within the ocean depend on the surface origin of a parcel of water. Mix-ing between waters of different salinities occurs within the ocean, and so the original salinity changes gradually. How-

What is Ocean Acidification? The Chemistry. When carbon dioxide (CO 2) is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals. These chemical reactions are termed ocean acidification or OA for short.he Chemistry.

- Several factors can influence how a chemical will behave and the hazards the chemical presents, including the severity of the response: 1  Concentration of the chemical. 2  Physical state of the chemical (solid, liquid, gas). 3  Physical processes involved in using the chemical (cutting, grinding, heating, cooling, etc.).

Halocline Because salinity (in concert with temperature) affects the density of seawater, it can play a role in its vertical stratification. Essentially, lower salinity water (= lower density) floats on top of higher salinity water (= higher density).

Oceans Quest One factor that affects the ocean temperature is the depth. The temperature of the ocean decreases as the depth increases. The temperature change does not happen gradually. Water in the ocean can be divided up into three layers by temperature. Surface zone, Thermocline, and the Deep zone, are the three layers of the ocean.

- Effects on other chemicals in the water • A change in the pH can alter the behavior of other chemicals in the water. The altered water chemistry may affect aquatic plants and animals. For example, ammonia is relatively harmless to fish in water that is neutral or acidic.

- More gas can be dissolved in cold water than in warm water. Animals, such as salmon, that require a high level of dissolved oxygen will only thrive in cold water. Increased water temperature can also cause an increase in the photosynthetic rate of aquatic plants and algae.This can lead to increased plant growth and algal blooms, which can be harmful to the local ecosystem.f the water temperature changes by even a few degrees, it could indicate a source of unnatural warming of the water or thermal pollution. Thermal pollution caused by human activities is one factor that can affect water temperature.

Properties of Seawater Temperature influences density. For pure water, density increases as the temperature decreases. Salinity influences this relationship in that the saltier the water, the denser it becomes. Furthermore, salinity lowers the freezing point to below 0°C (32°F).

pH -- Water properties Importance of pH. The pH of water determines the solubility (amount that can be dissolved in the water) and biological availability (amount that can be utilized by aquatic life) of chemical constituents such as nutrients (phosphorus, nitrogen, and carbon) and heavy metals (lead, copper, cadmium, etc.).

- The density of seawater plays a vital role in causing ocean currents and circulating heat because of the fact that dense water sinks below less dense. Salinity, temperature and depth all affect the density of seawater. Density is a measure of how tightly a certain amount of matter is packed into a given volume.

Conductivity, Salinity & Total Dissolved Solids The conductivity of seawater is dependent on the salinity and temperature of the water 38. Measurements will vary between the Equator and the poles as well as with depth due to conductivity’s dependence on temperature 38. As with conductivity, the expected salinity of a body of water can only be estimated.hen water temperature increases, so will conductivity 3. For every 1°C increase, conductivity values can increase 2-4% 3. Temperature affects conductivity by increasing ionic mobility as well as the solubility of many salts and minerals 30.

Seawater Composition Variations occur in ocean salinity due to several factors. The most common factor is the relative amount of evaporation or precipitation in an area. If there is more evaporation than precipitation then the salinity increases (since salt is not evaporated into the atmosphere).

Factors that affect boiling point of water? im conducting an investigation on the factors that affect the boiling point of water. my hypothesis is that the densest substances are going to create the highest boiling point. so far i have tested NaCl, sugar, and baking soda under the same variables. i found that baking soda, the densest substance, created the highest bioiling point. how can i properly conclude my report and explain why this is so?

Sea Surface Salinity Salinity varies due to evaporation and precipitation over the ocean as well as river runoff and ice melt. Along with temperature, it is a major factor in contributing to changes in density of seawater and therefore ocean circulation.

- Physical properties such as the density, viscosity and pour point of the oil all affect its behaviour. Dissipation does not occur immediately. The time this takes depends on a series of factors, including the amount and type of oil spilled, the weather conditions and whether the oil stays at sea or is washed ashore.

- As it cools, it begins to sink, and the process begins again. Convection results in the continual circulation of ocean water on a global scale. There are many factors that determine the strength of a current, as well as the route it will follow. Winds have the most important influence on the flow of currents, but tides, precipitation, evaporation rates, shape of the ocean floor, and inflow from rivers and adjacent seas are also important.

Density of Ocean Water There are two main factors that make ocean water more or less dense than about 1027 kg/m 3: the temperature of the water and the salinity of the water. Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water.

Properties of Seawater The salinity of seawater is determined by how much freshwater enters the ocean in the form of precipitation, melting sea ice, and runoff from rivers, and how much exits through evaporation.Salinity is higher in the temperate and tropical areas where evaporation rates are higher than in polar regions.he salinity of seawater is determined by how much freshwater enters the ocean in the form of precipitation, melting sea ice, and runoff from rivers, and how much exits through evaporation.

- Two of the most important characteristics of seawater are temperature and salinity –. together they control its density, which is the major factor governing the vertical. movement of ocean waters. Temperature Distribution in the Ocean. The temperature of seawater is fixed at the sea surface by heat exchange with the. atmosphere. The average incoming energy from the sun at the earth's surface is about. four times higher at the equator than at the poles.

- Ocean Heat. Three independent analyses show that the amount of heat stored in the ocean has increased substantially since the 1950s. Ocean heat content not only determines sea surface temperature, but also affects sea level and currents. Sea Surface Temperature. Ocean surface temperatures increased around the world during the 20 th century.
