Biological and Chemical Measurements from Two Antarctic Lakes

December 1998 to February 2000 data from Crooked Lake and Lake Druzhby in Antarctica's Vestfold Hills. The dataset contains measurements of ammonia, nitrite, nitrate, temperature, oxygen, and abundances of heterotrophic bacteria, cyanobacteria, ciliates, and rotifers. Data was collected by a team led by Prof J Laybourn-Parry and organized into physical, chemical, biological, and production folders.

Use Cases

• Modeling relationships between physical factors like temperature and oxygen and biological communities like ciliates and rotifers.
• Analyzing seasonal trends in nutrient concentrations such as ammonia, nitrite, and nitrate across multiple sampling depths.
• Studying microbial carbon production using bacterial production rate data measured in ng C l-1h-1.
• Comparing biological community structures, like cyanobacteria abundance, between the deep site CL and shallow sites LD1 and LD3.

Strengths

• Data spans 14 months from December 1998 to February 2000.
• Samples collected from four distinct geographic sites with precise coordinates.
• Includes interdisciplinary measurements across physical, chemical, and biological processes.

Limitations

• Sample size is limited to two lakes in a single Antarctic region.
• Some microscopy data, like bacterial sizing, is missing for samples marked 'JLP'.
• Sampling frequency and depths were not consistent throughout the study period.
