Preliminary Metadata record for data expected from ASAC Project 1126
See the link below for public details on this project.
---- Public Summary from Project ----
Previous work on anti-freeze proteins (AFPs) in bacteria isolated from saline lakes in the Vestfold Hills, has shown that only around 10% of isolates possessed AFP activity. This suggests that the majority of bacteria may be using other mechanisms to avoid freezing or possibly are non-functional at sub-zero temperatures. We propose building on our previous work to ascertain if AFP occurrence is characteristic of particular taxonomic groups, or whether its evolution is random among different species.
The fields in this dataset are:
Lake
Date
Air Temperature
Ice Thickness
Sample Type
Depth
Height of ice core sample from ice/water interface
Thickness of Ice core sample
Salinity
Water Temperature
Nitrate
Nitrite
Ammonia
Phosphate
Bacteria
Flagellates
Chlorophyll
DOC - Dissolved Organic Carbon
COV of DOC - Coefficient of Variance

——项目公开摘要——
此前针对维斯福尔兹丘陵（Vestfold Hills）盐湖分离细菌开展的抗冻蛋白（anti-freeze proteins, AFPs）相关研究显示，仅约10%的分离菌株具备抗冻蛋白活性。这提示多数细菌或通过其他机制抵御冻害，或在亚零温环境下丧失活性。本研究拟基于前期工作，探明抗冻蛋白的存在是否为特定分类类群的固有特征，抑或是其在不同物种间的演化过程呈随机分布。
本数据集包含以下字段：
湖泊（Lake）、采样日期（Date）、气温（Air Temperature）、冰层厚度（Ice Thickness）、样品类型（Sample Type）、采样深度（Depth）、冰芯样品距冰水界面的高度（Height of ice core sample from ice/water interface）、冰芯样品厚度（Thickness of Ice core sample）、盐度（Salinity）、水温（Water Temperature）、硝酸盐（Nitrate）、亚硝酸盐（Nitrite）、氨氮（Ammonia）、磷酸盐（Phosphate）、细菌（Bacteria）、鞭毛虫（Flagellates）、叶绿素（Chlorophyll）、溶解性有机碳（Dissolved Organic Carbon, DOC）、DOC变异系数（Coefficient of Variance, COV）
