IS33A:
Technological Advancements in Phytoplankton Ecology: Observation Techniques and Platforms, Data Analysis and Interpretation, and Model Development II
Session ID#: 11400
Session Description:
Phytoplankton are a vital component of the aquatic ecosystem and affect water chemistry through nutrient uptake, alteration, and excretion. Shifts in phytoplankton community structure serve as indicators of environmental perturbations to aquatic systems, including climate change, eutrophication, and pollution. Furthermore, bloom-forming species can cause negative effects including hypoxia, high turbidity, or toxicity.
Technologies for assessing phytoplankton distribution and ecological variables have improved in efficiency and spatial/temporal resolution through the development and advancement of laboratory techniques, adaptation to new in-situ platforms, and incorporation into regional observation systems.
Phytoplankton observations range from simple detection (e.g. remote sensing, optical techniques) to species discrimination (e.g. microscopy, spectral fingerprinting, molecular approaches), to community structure determination (i.e. chemotaxonomic analysis). Additionally, laboratory and in-situ measurements of phycotoxins, macro- and micronutrients, and chemical and physical variables provide a critical ecological context for phytoplankton observations. In turn, advancements in data interpretation and modeling offer insight into phycological observations and allow for forecasting and prediction of harmful algal blooms, providing resource managers with tools to mitigate negative effects.
We invite presentations focused on the development or use of new or improved observation technologies, data analysis and interpretation techniques, and model development that address the many aspects of phytoplankton ecology.
