PC11A:
Utilizing Ecological and Oceanographic Records to Understand Ecological Responses to Modern Climate Change


Session ID#: 36896

Session Description:
It is important to evaluate past instances of global ocean change and ecosystem responses to these events in order to improve understanding of modern ecological processes and predict results of modern climate change. Paleoecological and paleooceanographic data are key tools for evaluating ecosystem processes on multiple timescales (e.g. regime change, biodiversity, natural variability, recovery). This session will focus on using these types of data as tools to characterize future environmental and ecological change, quantify deviations from cycles of natural variability, and inform modern conservation practices. This may include research from a wide range of ecological (organisms to ecosystems) and temporal (sub-annual to millennial) scales. We welcome investigations of past episodes of change as an analog for modern systems, in addition to studies that integrate modern and historic data to extend the record of modern climate change. We invite the use of novel or unconventional methods that use environmental and ecological data to evaluate future climate, assess impacts on marine biota, and provide insights into best conservation practices for navigating an uncertain future.
