OB44G:
Planktonic Recorders: Using Tiny Organisms to Understand Past, Present, and Future Oceans II Posters

Session ID#: 93238

Session Description:
Global plankton communities are vital to food web dynamics, ecosystem functioning, and the global cycling of carbon, nutrients, and oxygen. Modern-day ocean acidification, warming, and human activity are impacting plankton communities, leading to shifts in geographic distribution (i.e., biogeography) with ramifications for biogeochemical cycles. A multi-disciplinary approach is required to fully understand marine biogeochemical cycles, from planktonic microbial activities and biomineralization to functional diversity and plankton biogeography. Planktonic calcifiers, in particular, are potentially sensitive bioindicators of both present and past responses of the ocean system to change. The fossil record provides context for these modern-day observations and future predictions with evidence of changes in the plankton community over evolutionary timescales.

We invite contributions that use observations and models to investigate the physiological, chemical, biogeochemical, and physical processes controlling and driving changes in plankton communities in the past, present, or future. Topics may include changes in biogeography, biodiversity, biomineralization, food web dynamics, and/or contributions to biogeochemical cycling and their impacts, from intra-seasonal to interglacial time scales and from the cellular to basin scale. This session aims to bring together biogeochemical, microbial, and paleo oceanographers to detail recent work on better understanding the effects of a changing ocean on these important marine organisms.
