Porewater measurements of dissolved nutrients (ammonia, nitrate/nitrite, phosphate) from core monitoring sites in the GCE-LTER domain following hurricane Irma from October 2017 to October 2018.

To access the effect of hurricane Irma on the GCE domain, porewater samples were collected to evaluate porewater nutrient concentrations at four core GCE monitoring sites (7, 8, 9 and 11). A limited number of samples were collected in October 2017 (a month after the storm surge from hurricane Irma hit the east coast of the United States) and then all sites were sampled in Nov 2017 and in Jan, Feb, Apr and Oct 2018. Porewater samples were obtained from approximately 10 cm depth using Rhizon samplers and then analyzed for ammonium, nitrate + nitrite, and phosphate concentrations.为探究飓风艾尔玛（Hurricane Irma）对GCE区域的影响，本研究采集孔隙水样品以评估GCE四个核心监测点位（点位7、8、9及11）的孔隙水营养盐浓度。2017年10月（飓风艾尔玛风暴潮袭击美国东海岸后的一个月）仅采集了有限数量的样品，随后于2017年11月以及2018年1月、2月、4月和10月对所有点位完成采样。孔隙水样品通过Rhizon采样器（Rhizon samplers）在约10厘米深度处采集，随后对其中的铵盐（ammonium）、硝酸盐+亚硝酸盐（nitrate + nitrite）及磷酸盐（phosphate）浓度进行了分析。
