Field Trips Breaks

The ICP13 will include five half-day plenary sessions and three extensive poster sessions and will include the following themes:

1. Proxy development, new model and statistical tools

The paleoclimate toolbox has expanded considerably over the past few decades. There are now a wide variety of proxies from microfossil assemblages, sediment properties, stable isotopes, trace metals, radiogenic isotopes, and organic biomarkers. Proxy development has also gone hand in hand with an improved understanding of how both biological and chemical proxies function as carriers of environmental information.

Statistical techniques have also advanced, providing better inference models based on the relationships between these proxies and the targeted environmental variables. Climate and Earth system models now incorporate more complex processes and have higher spatial resolution. Thus, a range of oceanic physical, chemical, and biological processes can be examined, to better understand their influence on climate-relevant variables.

This session will showcase the latest advances in this broad field, by welcoming presentations about the calibration and application of new proxies, along with novel statistical and modelling approaches, and their usage in teasing out and interpreting paleo-environmental information from all available archives and model experiments.


2. Geobiology- new frontiers in paleoceanography linking paleoclimatic changes with biology and evolution

Geobiology describes the interaction between the physical Earth and the biosphere. By combining information about the past development of more than one species, geobiology offers the opportunity to explore the dynamics of biological communities over long temporal periods. Geobiology has recently benefitted from major methodological and analytical advances, e.g., ancient DNA (aDNA) and novel modelling approaches. Yet, we are just at the beginning of understanding past marine ecosystem developments (or evolution) as well as the forcing and feedbacks between the biological and physical environment. Making full use of the potential of geobiology may significantly enhance ecological interpretations and our understanding of ecosystem responses to climate change – also in the future.

We invite contributions that address past developments of marine biological communities and their environment based on all types of biological proxy records ranging from standard paleoecological methods to new proxy developments.


3. Carbon-climate feedbacks across time scales

The Earth climate history is characterized by long-term gradual changes interrupted by more abrupt climatic transitions. These abrupt changes were mostly accompanied with significant variations in atmospheric pCO2 and carbon perturbations. However, the mechanistic links and feedbacks between climate and the carbon cycle remain elusive, warranting further in-depth understanding of interactions of processes governing the ocean-ice-atmosphere-solid earth system using a variety of archives (e.g., ice cores and marine and terrestrial deposits) and methods (proxies and numerical models).

This session invites contributions that improve our understanding of carbon-climate feedbacks across all timescales. It encompasses, but is not limited to, atmospheric pCO2 reconstructions, variations in the strength of the marine biological pump, air-sea CO2 fluxes, climate sensitivity, changes in ocean surface and interior carbon storage, solid earth influences, terrestrial biosphere changes, and proxy-model based quantification of timing and magnitude of global ocean carbon changes during the Cenozoic.


4. Ocean circulation and climate system dynamics

Climate is largely governed by ocean dynamics over a wide range of spatial and temporal scales. In particular, the ocean circulation plays a central role in climate dynamics through air-sea interactions, transport of heat and salt, and storage of heat and carbon. Reconstructing the ocean's past is critical for understanding the dynamics of the climate system as a whole.

This session welcomes presentations focusing on ocean circulation and its links with the climate system dynamics. We seek contributions encompassing observational, theoretical, and modelling studies of ocean circulation in the past, present and future, with a particular focus on: (1) paleoceanographical reconstructions on various timescales and derived from marine paleo-proxies; (2) key processes that could force or generate changes in ocean circulation; (3) Impact of changes in the oceanic circulation on climate system dynamics (e.g. ENSO, Monsoons…); (4) developing and applying numerical models to simulate changes in ocean circulation and its impact on climatic changes.


5. Role of Southern Hemispheric processes

Since the formation of the Southern Ocean during the early Oligocene, the Antarctic Circumpolar Current (ACC) has provided an unique link that connects all the major ocean basins. Two of the main water masses that are part of the global meridional ocean circulation are formed at high southern latitudes: Antarctic Bottom Water and Antarctic Intermediate Water. Variations in the formation and transport of these water masses and of the ACC have a significant impact on climate and the carbon cycle. In addition, Southern Ocean biological productivity potentially also exerts a significant control on the global carbon cycle.

Processes occurring in the tropical Indo-Pacific are also a major driver of climate variability. Modes of variability such as El Niño Southern Oscillation strongly impact tropical to mid-latitude hydrological cycle. However, changes in these mode of variability are poorly constrained for many time periods.

For this session, we invite contributions from both proxy reconstructions and modelling studies, which advance our knowledge of Southern Hemispheric processes and their impact on climate and biogeochemistry across Cenozoic and Quaternary timescales.


6. Ice-sheet/ocean interactions: drivers and impacts

Sea-level rise is perhaps one of the most alarming repercussions of present-day climate change. It is therefore necessary to gain a more thorough understanding of the dynamics of continental ice sheets, including the complex interactions between buttressing ice shelves, ocean circulation and warming ocean waters, in order to increase our confidence in future sea-level and climate projections. Moreover, the sizes and geographic distributions of continental ice sheets determine an important slow feedback in the radiative balance of climate, which needs to be resolved for a better understanding of climate responses relative to radiative changes. This session is a focal point for studies on ice-sheet variability, ice-ocean interactions, crustal deformation, and ice-sheet impacts on climate, from radiative feedbacks to changes in ocean and atmospheric circulation, marine productivity, and the carbon cycle.

For this session, we invite contributions from both reconstructions and modelling, which shed light on the role of ice-sheets in climate sensitivity and ice ocean interactions from regional to global scales.
