Traduction de «Surface temperature water » (Anglais → Français) :

The ‘El Niño’ phenomenon is characterised by rising temperatures of surface sea water, which interact with the atmosphere and cause different extreme events, from floods to droughts.

By having a closed wall you can isolate from that surface temperature, pull cooler water from down below and have the water at a more appropriate temperature for proper husbandry of the fish, which manifests in better feed conversion rates, better growth rates and lower mortality, so it just makes business sense.

This rise will largely offset reductions in water requirements from higher CO that plants will need. Therefore, it is expected that our water requirements may not necessarily rise due to higher temperatures, because those needs will be offset by higher CO. However, evaporation from ponds, irrigation reservoirs, glaciers — evaporation that occurs not from plants but from free-water surfaces — will be greatly accelerated, and that is ...[+++] an important point of which we need to be aware.

Question No. 140 Ms. Kirsty Duncan: With respect to development of the oil sands, its impacts on the environment and surrounding communities, and the economic effects of these impacts: (a) what, if any, steps has the government taken to establish air emission limits or air quality standards to achieve the World Health Organization’s Air Quality Guidelines to protect air quality and human health; (b) what, if any, steps has the government’s sector-by-sector approach taken to regulate carbon emissions in the oil sands to ensure the oil sands industry makes appropriate reductions in its greenhouse gas (GHG) emissions to contribute to Canada’s GHG emission reduction goal of 17% below the 2005 level; (c) what, if any, studies has the governmen ...[+++]t undertaken to examine the effect of the oil sands expansion on (i) GHG emissions, (ii) Canada’s ability to meet its GHG emission reduction goals, (iii) Canada’s contribution to the goal of staying below a 2°C increase in global average surface temperature, relative to the pre-industrial level, as articulated at the G8 meeting in L’Aquila, Italy and at the United Nations Framework Convention on Climate Change negotiations through the Copenhagen Accord in December 2009 and the Cancun Agreements in December 2010, (iv) the full suite of sustainability criteria, including environmental, economic and social sustainability, and (v) what were the results of any studies identified in (c)(i), (c)(ii), (c)(iii), and (c)(iv); (d) what, if any, studies has the government undertaken to examine (i) the scope of oil sands expansion if the oil sands sector is not required to deliver its proportional share of GHG reductions, (ii) the impacts such a decision would have on other sectors’ allowable GHG emissions, (iii) whether other sectors of the Canadian economy would have to do more than their proportional share to reduce emissions, (iv) what were the results of any studies identified in (d)(i), (d)(ii), and (d)(iii); (e) what, if any, studies ...

Question No. 419 Ms. Kirsty Duncan: With respect to the risk of corrosion and spills and other safety concerns arising from the transport of bitumen in pipelines, and to government action to address these risks: (a) how does diluted bitumen compare with West Texas Intermediate (WTI) in terms of (i) abrasive material content, (ii) acid concentration, (iii) sulphur content, (iv) viscosity; (b) to what extent is diluted bitumen more likely than WTI to cause corrosion or erosion in the pipelines through which they respectively flow; (c) what is the composition of diluted bitumen in Canada; (d) what are all of the volatile chemicals, persistent organic pollutants or carcinogenic substances ...[+++] present in diluted bitumen in Canada; (e) in the process of diluting bitumen in Canada, what are the (i) natural gas condensates used, (ii) other petroleum products used; (f) what is the process by which diluted bitumen corrodes pipelines, with specific reference to (i) abrasion, (ii) friction, (iii) high pressure, (iv) settling of sediment, (v) velocity, (vi) sulphur-reducing bacteria, (vii) other significant factors; (g) for all proposed or existing National Energy Board (NEB)-regulated pipelines, what is (i) the amount of hard sediment passing through the pipeline annually, (ii) the average pressure, (iii) the average temperature; (h) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to determine whether diluted bitumen can flow safely through pipelines; (i) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to determine whether or not conventional crude should be distinguished from diluted bitumen when setting minimum standards for pipelines; (j) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to design safety and spill responses and spill liability management capabilities that are appropriate specifically to diluted bitumen; (k) how does a diluted bitumen sp ...

The pH of the effluent discharged to surface waters shall be between 6 and 9 (unless the pH of the receiving waters is outside this range), and the temperature shall be below 40 °C (unless the temperature of the receiving water is above this value).
