I'm writing a research paper, and one of the conditions is that one of my resources MUST be an academic article from an academic journal. My topic is Paper Recycling. I have been googling for the past half an hour and have been unable to find one, perhaps im looking in the wrong places. Could anyone maybe tell me about a free online academic journal please. Thanx.

Hello everyone, My question is what happens to substances that contaminate deep ocean water and deep aquifers in the ground? For ocean water, my guess is that the pollutants enter the organisms found in the oceans and thereby enter into the food chain. A very vage answer, does anyone have a more solid answer? For deep aquifers, only source of pollution I can think of is deep injection wells. Now wht i dont knw is wht exactly HAPPENS to these pollutants, i get that they harm us and all but question is what happens to them? My paper is due in less than a day, any help would be appreciated. Thankyou.

Thank you so much mooeypoo, really appreciate your help. Ok so, i looked it up and realised that the density of water increases as temprature decreases till a certain temp(4). So, water at the bottom doesnt circulate because its cold and dense, it has a lot of mass above it hence increasing the pressure, also is it right to say the kinetic eneryg of the molecules is less due to low temprature so less movement? Any other reasons possible? I've tried to look up the second part of the question, but haven't really found information related to it. Could you maybe give me a hint or two? Thanx

Hi all, I have been told to do a presentation on a topic that I have no idea about, and can't find much info on! I tried googling and all but it wasn't much help. The question is: Why does it take so long for deep ocean waters to circulate through the hydrologic cycle? What happens to substances that contaminate deep ocean water or deep aquifers in the ground? From the little knowledge i've got, I think the reason deep ocean waters take so long to circulate is because the deeper part of the ocean is colder. Colder because less sunlight reaches it. But, then it its colder shouldnt the density be less and it should rise to the top ?:s I could be wrong, as im pretty new to this subject. Any help would be highly appreciated. Thank you .
