Lake Bonney Autonomous Lake Profiler and Samplers (ALPS): BBE moldanke Fluoroprobe data

Summary

Abstract: 

Knowledge of the McMurdo Dry Valley (MDV) lakes is limited by winter access, a period which is most relevant in understanding the habitability of other icy worlds and critical to understanding the overall function of these lakes.  Owing to the lack of winter access, data that normally require human presence are incomplete.  Our goal was to conduct the first year-round investigation of the biogeophysics of these unique lakes.  An important part of the McMurdo Long Term Ecological Research (LTER) is evaluating carbon and nitrogen budgets in perennial ice-covered lakes. This data set addresses this core area of research and quantifies the fluorometric characteristics of phytoplankton species year-round
