|
| The most important variable characteristics of estuary water are the concentration of dissolved oxygen, salinity and sediment load. |
|
| For this reason, many steel plants desulfurize blast-furnace iron before it is refined into steel, since at that stage it contains practically no dissolved oxygen, owing to its high silicon and carbon content. |
|
| Calcium peroxide may facilitate depositing floccules and clearing turbid water thus improves the photosynthesis of natant foliage to increase dissolved oxygen. |
|
| For example, when animal manure or other organic material like food processing wastes decompose, they can deplete the dissolved oxygen in the water, and in so doing suffocate fish and other aquatic organisms. |
|
| Each type of water body differs from the others in what it has to offer fish, from its variety of food and cover to its temperature range, water clarity, and the amount of dissolved oxygen available to pass over their gills. |
|
| Abyssal waters retain several cubic centimetres of dissolved oxygen per litre, because the sparse animal populations do not consume oxygen faster than it is introduced into the abyssal zone. |
|
| Uraninite, the solid reduced form of uranium, is not very stable in the presence of dissolved oxygen. |
|
| The zone is characterized by abundant dissolved oxygen, sunlight, nutrients, generally high wave energies and water motion, and, in the intertidal subzone, alternating submergence and exposure. |
|
| This process leads to reduced concentrations of nitrate, phosphate, and silica in these waters and, during times of maximum daylight organic production, supersaturation of epilimnion waters with respect to dissolved oxygen. |
|
| It may cause them to overproduce mucous, blocking the absorption of dissolved oxygen, or accumulate on the gill surfaces, causing them to hyperventilate or smother. |
|
| The deepest layer of water in such a lake does not contain any dissolved oxygen. |
|
| Such lakes are of little use to humans and have a poor ecosystem due to decreased dissolved oxygen. |
|
| This decomposition process consumes oxygen, which reduces the concentration of dissolved oxygen. |
|
|
|
| When dissolved oxygen levels decline to hypoxic levels, fish and other marine animals suffocate. |
|
| The turtles can take up dissolved oxygen from the water using these papillae, in much the same way that fish use gills to respire. |
|
| Large amounts of dead matter decomposing in the ocean causes the surrounding levels of dissolved oxygen to decrease. |
|
| The resulting lack of dissolved oxygen greatly reduces the ability of these areas to sustain oceanic fauna. |
|
| Low dissolved oxygen conditions are often seasonal, as is the case in Hood Canal and areas of Puget Sound, in Washington State. |
|
| The bog environment is acidic, with a low concentration of dissolved oxygen. |
|
| There were corresponding increases in dissolved oxygen, an indicator of a healthy river environment. |
|
| The anodic passivators discussed here refer to inhibitors that enhance chemisorption of dissolved oxygen and migrate readily to the anodic sites. |
|
| Feeding should be done in the late morning or early afternoon when dissolved oxygen levels are high so fish have enough time to recover from the high oxygen-demanding feeding activity before nightfall. |

| In semi-static tests, it is recommended that dissolved oxygen be measured more frequently, preferably before and after each water renewal or at least once a week. |
|
| In the first two studies, dissolved oxygen was at low but acceptable levels at the start of the experiment, but it dropped rapidly after a few days to levels that are uncomfortable for most animals. |
|
| It is not recommended to supply a pond with water from another pond, since this water may carry diseases and the level of dissolved oxygen may be lower. |
|
| To extend the shelf life of beer, for example, without adding any preservatives, the water used to produce it must contain as little dissolved oxygen as possible. |
|
| The documentation transmitted by Portugal demonstrates that the discharge will not have any impact on the dissolved oxygen rate, the trophic status, the transparency and the benthic community of the receiving waters. |
|
| The temperature and dissolved oxygen concentration of water in the different treatments were measured every 8h with an oxymeter YSI-55 and a YSI-63 pH probe. |
|
| Because dissolved oxygen in the water column is continuous with water in the coelenteron, it may lead to increased oxygen concentration within the coral. |
|
| In the North Atlantic Ocean, dissolved oxygen and sea surface temperature were found to be the principal drivers of jellyfish biomass distribution. |
|
|
|
| In addition, water quality is affected by the interaction of dissolved oxygen with organic material and various chemical transformations that may take place. |
|
| Despite shallow depth, the bay usually has a strongly developed pycnocline, and has seasonally strong vertical gradients in temperature, salinity, and dissolved oxygen. |
|
| Portions of the deep ocean will periodically lose all of its dissolved oxygen allowing bacteria that live without oxygen to flourish and produce hydrogen sulfide gas. |
|
| Spirax Sarco has launched a pressurised deaerator system that reduces the dissolved oxygen content of boiler feedwater to virtually nil without chemical treatment. |

| In other words, nitrogen sparges the water to remove any dissolved oxygen and C02, and humid air in the head space is replaced by pure, inert nitrogen. |
