When soil is washed away by water, nitrogen can be carried with it. after a tsunami, there is an excessive amount of runoff. if there were plants in the ground then there would not have been a problem. but because of the wave, all the topsoil was drifted away and so off fishall the water was run off. the nitrogen can be a kind of pollution because it could get into other rivers or streams and start killing.
The ocean is one of the biggest reservoirs of carbon. the ocean can hold about 50 times more than the atmosphere can. usually there is a quick 2-way exchange of carbon. it is with the ocean's surface and the atmosphere. but carbon can be held at the bottom of the ocean for centuries. i predict that because a tsunami has water from deep areas of the ocean rise it could have made alot of carbon, that has been stored, come up. Carbon readings in the atmosphere could have been very high in the month of December in Indonesia. it could have thrown the carbon cyle off because there would be alot of carbon going into the soil and the air wch would mean alot of it will return to the ocean's surface.
phosphorus is can be located in roch or sediment. with the help of wind and rain, it gradually gets eroded away and sent into the air. the phosphorus gets into the water adn can stay there. i believe sense there was so much water and most of the topsoil was washed away, that alot of phosphorus was released into the air. plants also contain phosphorus in them. when a plant dies, the phosphorus is also released into the air. because there were so many plants that died after the wave, i believe there would be an excessive amount of phosphorus in that time period.
i believe that because there was so much water, and because it is hot, that there was alot of water evaporation. because there is so much evaporation there is going to be alot of precipitation. also, the tsunami created an excessive amount of destruction and that causes debris to be everywhere. when it rains, some of that debris will be drifted off. some might go into water supplies and some might be runoff. the runoff then goes into the ocean, causing trash and pollution.
