PC007. Oceanic Climate and Ecosystem Variability and Change in Eastern Boundary Upwelling Systems Session ID#: 28753 Session Description: Coastal climates along the major oceanic eastern boundaries are governed by a complex interplay of alongshore winds and clouds shaped by topography, ocean upwelling and eddies. These factors combine to yield marine ecosystems that are highly productive and diverse, and at the cutting edge of major climate trends including hypoxia and acidification. Future projections of the climate and ecosystem response of EBUS to global change are compromised by poor resolution of the scales of coastal variability. We invite studies of EBUS based on observational analysis and high-resolution earth system models, aimed at characterizing patterns of variability and detection and attribution of trends in climate and ecosystem processes. Studies that identify mechanisms of variability and change are especially encouraged. Primary Chair:  Curtis A.

The Ocean as a Mediator of Climate and Climate Change Session ID#: 28178 Session Description: The ocean plays a key role in shaping Earth’s climate on timescales spanning seasons to millennia. As the largest reservoir of heat and carbon in the climate system, the ocean is critical for seasonal to decadal climate prediction, projecting climate change over the coming centuries, and making sense of the paleoclimate record. The evolution of climate over the next decade depends sensitively on the state of the ocean today and its coupling to the atmosphere. Earth’s response to greenhouse gas forcing over the 21st century hinges on how heat and carbon are taken up and stored by the ocean. And the climate of the Last Glacial Maximum is thought to have been associated with an ocean circulation that is substantially different from today’s. Understanding and accurately predicting climate at all timescales requires realistic representations of how the ocean exchanges energy, momentum, freshwater, and carbon with the other components of the climate system. This session aims to explore large-scale ocean interactions with the atmosphere, cryosphere, and biosphere in both observations and models of varying complexity. We welcome contributions from studies that examine how the ocean mediates the mean climate, climate variability, and climate change in the past, present, and future.

The Role of the Southern Ocean in the Global Carbon Cycle Session ID#: 27989 Session Description: The Southern Ocean is estimated to account for approximately half of the global oceanic sink of anthropogenic carbon, thus playing a key role in the climate system.  Changes in the carbon cycle in this region are also thought to exert a strong influence on glacial-interglacial cycles.  Recent work has highlighted large interannual variability in the Southern Ocean sink, and new observational estimates of the carbon cycle are emerging from biogeochemical floats and atmospheric measurements. The Southern Ocean remains, however, the basin least constrained by observations, with the largest disagreement among climate models and between models and observations. Changes to our understanding of the Southern Ocean carbon cycle have significant implications for the carbon budgets of the atmosphere and land components of the climate system. We invite abstracts that investigate these topics in both the modern and paleo-climate eras, in particular the magnitude and spatial distribution of the different parts of the Southern Ocean carbon cycle; the variability of the carbon cycle on seasonal to decadal timescales and centennial to glacial-interglacial timescales; and the impact on and interactions with the atmosphere, land, and world ocean.

Towards a 1.5oC World: The Ocean Response Session ID#: 28536 Session Description: The Paris Agreement (COP21) has set an aspirational goal of limiting global surface warming to 1.5oC. This goal requires immediate action, with almost all future scenarios indicating that carbon dioxide removal or other geoengineering approaches will be needed. Irrespective of geoengineering measures, emissions must peak in a little over a decade and then rapidly decrease to become zero or even net negative. Given the prominent role of the ocean in storing emitted carbon dioxide and excess heat, the exploration of the potential response of the ocean to a drop in or even negative emissions is of scientific interest and of societal relevance. This session welcomes abstracts exploring the response of the ocean under scenarios aiming towards a 1.5oC world and how it may feed back to the other components of the Earth system. Relevant issues may include hysteresis effects in ocean circulation or sea-ice, the response of the ocean carbon and other biogeochemical cycles, ecological impacts, and potential unanticipated impacts of geoengineering measures.
