Mercury concentrations in seaside sparrows (Ammospiza maritima) and marsh rice rats (Oryzomys palustris) and estimates of stable nitrogen and carbon isotopes in Barataria Bay and Breton Sound, 2015-03-18 to 2016-06-27

This dataset contains estimates of total mercury (THg) concentration in the blood of seaside sparrows (Ammospiza maritima) and marsh rice rats (Oryzomys palustris) in marshes west and east of the Mississippi River from 2015-03-18 to 2016-06-27. In addition, estimates of stable nitrogen (δ15N) and carbon (δ13C) isotope values in Barataria Bay and Breton Sound, as proxies of trophic position and the source of primary production, are also included.

本数据集涵盖2015年3月18日至2016年6月27日期间，密西西比河东西两侧湿地中海滨麻雀（Ammospiza maritima）与沼泽稻鼠（Oryzomys palustris）血液中的总汞（total mercury, THg）浓度估算值。此外，数据集还包含巴拉塔里亚湾（Barataria Bay）与布雷顿桑德湾（Breton Sound）内的稳定氮同位素（δ¹⁵N）及稳定碳同位素（δ¹³C）比值数据，上述同位素指标可作为营养级与初级生产力来源的替代表征参数。
