RAPID Effects oiling hydrologic remediation

项目摘要

This is a Rapid Response Research (RAPID) proposal to study the effects of oiling as a catastrophic disturbance on coastal elevation, as related to the biotic contributions of peat material. In response to the BP Deepwater Horizon oil-spill, the PIs will test the hypotheses that i) oiling, or hydrologic remediation designed to prevent oiling, will cause reductions in above- and below-ground production and peat accumulation, increases in soil respiration and decomposition rates, and ultimately result in net losses in elevation of baldcypress swamps, and ii) that the resilience of these habitats, with regard to these ecosystem processes, will be lower in oiled swamps than in undisturbed areas. The investigators will make use of historically-relevant data on above- and belowground production, tree growth, decomposition, and regeneration from previous long-term studies in coastal baldcypress swamps in Jean Lafitte National Park and other sites. Carbon dioxide, nitrous oxide and methane emissions from the wetlands will be measured, in anticipation that decomposition and other biogeochemical processes may shift in response to the disturbance. These sites were targeted for long-term studies because they are sensitive to changes in elevation as a result of high rates of sea level rise experienced throughout the region. These data will permit an assessment of both the direct and indirect impacts of oil spills and the proactive efforts made to reduce oiling on ecosystem processes in coastal freshwater swamp ecosystems that are found along the entire Gulf and Southeast Atlantic coasts. The research will provide managers and the public with information on the effects of the BP Deepwater Horizon oil spill and its hydrologic remediation on coastal wetland elevation, and will be disseminated via peer reviewed journal articles and briefs written for the public. An undergraduate student will be trained as part of the research.

这是一项快速响应研究（快速）提案，用于研究上油作为灾难性干扰对沿海高度的影响，与泥炭材料的生物贡献有关。 In response to the BP Deepwater Horizon oil-spill, the PIs will test the hypotheses that i) oiling, or hydrologic remediation designed to prevent oiling, will cause reductions in above- and below-ground production and peat accumulation, increases in soil respiration and decomposition rates, and ultimately result in net losses in elevation of baldcypress swamps, and ii) that the resilience of these habitats, with regard to these ecosystem在上油沼泽中的过程将比未受干扰的地区低。调查人员将利用与以前的生产，树木生产，树木生长，分解和再生的历史数据相关的数据，来自让·拉菲特国家公园（Jean Lafitte National Park）沿海秃头沼泽的长期研究。将测量湿地的二氧化碳，一氧化二氮和甲烷排放，因为预期分解和其他生物地球化学过程可能会随着扰动的响应而变化。这些地点是针对长期研究的目标，因为由于整个地区的海平面上升率高，它们对海拔的变化敏感。这些数据将允许评估漏油的直接和间接影响，以及为减少整个海湾和东南大西洋沿岸发现的沿海淡水沼泽生态系统的生态系统过程的积极努力。这项研究将为经理和公众提供有关BP Deepwater Horizon漏油事件及其水文修复对沿海湿地高程的影响的信息，并将通过为公众撰写的同行评审期刊文章和简介来传播。本科生将作为研究的一部分进行培训。
