A New Paradigm for Tropical-Extratropical Interaction
Speaker: Peter John Webster 

One of the outstanding questions in weather and climate dynamics is how the extratropics and tropics interact. Both regions possess distinct circulation features: westerly jet streams and propagating Rossby waves in the extratropics; and regions of strong convective heating and equatorial modes such as the Walker Circulation in the equatorial zones. How do phenomena in these two regions interact?

There is increasing evidence that the interaction from the extratropics to the tropics is episodic, with strong incursions of high amplitude potential vorticity propagating towards the equator. These incursions are hypothesized to be the result of “breaking” Rossby waves that have formed as instabilities of the westerly jet streams. The westerly jets result from the regional poleward advection of potential vorticity (PV) associated with low-latitude/subtropical heating. The Rossby waves tend to break over the mid-Pacific and Atlantic Oceans, becoming incoherent filaments advecting PV towards the equator. This flux closes the PV circuit, returning PV to the equator and satisfying the McIntyre-Haynes “impermeability theorem” that states that net flux of PV on an isentrope across a latitude circle must be zero.

Why do the extratropical Rossby waves break recursively in the outflow regions of the major jets? It is hypothesized that the zonal and meridional structure of the basic state associated with the outflow region so distorts the Rossby waves that the waves become irreversibly unbalanced. Thus, distinct corridors of extratropical-tropical interaction are formed. These corridors have been referred to as “westerly ducts” that stretch between the extratropics and the tropics and between the hemispheres.

These ideas are tested using a series of simple theoretical and numerical experiments. Within this construct, there is little place for a zonally symmetric Hadley Circulation, often the center of extratropical-tropical interaction except within a physically unrealistic environment where the advective flux of PV is zero everywhere. We replace this idea with concept whereby poleward fluxes of PV, generated by regional heating, are balanced by Rossby wave dynamics that return PV towards the equator. The paradigm allows a holistic view of both the extratropical and tropical circulations and how they interact.

Atmospheric Chemistry from Space: Past, Present and Future
Speaker: Paul A Newman 

Over the last 100 years, huge strides have been made in our understanding of the composition and chemistry of the Earth’s atmosphere, and satellites have played a major role in these advances. The first ideas to measure ozone from space were published in the late-1950s, prior to the first satellite images of the Earth (Explorer 6 in August 1959). By the late-1960s, vertical profiles of ozone were being made by the Orbiting Geophysical Observatory (OGO-4) satellite, and in 1970 the backscatter ultraviolet (BUV) experiment with an instrument dedicated to ozone measurements was launched on the Nimbus 4 satellite. As is well known, ozone both absorbs ultraviolet (UV) and infrared radiation, and ozone is the principal screen for harmful UV radiation. The 1974 Nature paper by Mario Molina and Sherry Rowland uncovered the damaging effects of chlorofluorocarbons (CFCs) on the ozone layer and pushed ozone observations into the forefront of science. The discovery of the Antarctic ozone hole accelerated ozone research and increased observational efforts. This work quickly showed that CFCs were indeed leading to large Antarctic ozone depletion. Satellites now give us daily-global pictures of our atmosphere from pole-to-pole from European, US, and Asian satellites.

In this presentation I will discuss the history of atmospheric chemistry observations from space, with a particular emphasis on ozone from the mesosphere to the boundary layer. I will review current satellite capabilities and show how satellite observations and models are now merging to reveal comprehensive pictures of atmospheric composition and change. I will then provide some guesstimates and opinions on the future of atmospheric chemistry using model projections and some extrapolations of technology. In particular, I will discuss 1) a greater future ability to measure surface pollutants, 2) improvements in the interactive science of land-ocean-biosphere-atmosphere and their ability to do “bottom-up” emissions, 3) the future progression towards smaller satellites and new technologies combined with continually improving computer horsepower, and 4) the shifting of science towards societal needs of “warnings” and public policy information.

From Ice to Trees: Surprising Insights Into Past and Present Processes that Scuplt Our Earth
Speaker: Jill A Marshall

The Critical Zone (CZ) integrates the influence of rock properties, climate (expressed as wind, water, ice and biota) and tectonics through time. We may describe a region as wet or cold, with soft or hard rock, forested or grassy, yet grand challenges remain in discerning how such characteristics inhibit or promote earth-shaping mechanisms. For example, with few exceptions, we are yet unable to predict how bedrock is damaged and converted into soil despite major advances in quantifying soil production rates. Complicating matters, the imprint of past climates can be difficult to discern in unglaciated terrain. Together, these gaps limit our ability to characterize CZ architecture, develop mechanistic geomorphic laws, and model facets of CZ and landscape evolution. Here I present results generated via a broad suite of tools ranging from fieldwork, to paleoclimate simulations, to rock mechanics that provide insight into earth-shaping mechanisms.

One of the surprises is the pervasive influence of cold climes on weathering, enhanced soil production, and erosion across unglaciated lands. I unearthed these findings from lake cores spanning three climate intervals, and more broadly, from applying frost weathering models at the continental scale. Shifts from tree- to frost-driven processes likely extend beyond glacial intervals, thus vigorous frost activity may be a key sculptor in unexpected places. Secondly, in forested terrain, we presume that trees play a significant role in creating soil, with models centered on tree throw. Combining force sensors at the tree-rock boundary with precipitation, solar radiation, wind, and tree sway data, I have begun to quantify tree-driven soil-production mechanisms. Data suggests that trees damage and detach rock due to daily water uptake, rain, and wind events, while charismatic tree throw may matter less than belowground damage. The frequency, magnitude and style of wind-driven tree forces varies among species. This suggests that changes in water availability and tree structure, driven by variations in lithology and climate, may greatly influence soil production rates. These results highlight the synergistic and surprising findings that are the hallmark of interdisciplinary collaborations, and suggest a way forward to new explicit, mechanistic surface process knowledge.

Introductory Remarks

Gravity as a Measure of Climate Change
Speaker: Byron D Tapley

The mass of Earth System varies from redistributions within and exchange between the Earth System Components. These mass variations have an associated energy and momentum variation. These elements are significant contributors to variations in both weather and climate. Water movement at diurnal, monthly, annual and decadal periods is a significant contributor. Understanding the processes involved in the mass variation, within and between, the Earth System components is essential to interpreting the current conditions and forecasting future states of the Earth System.

The mass change involved in these system interactions has an associated gravity change signal which can be measured as a means of both monitoring and understanding the interactions. To fully understand the signal, repeated global and near synoptic measurements of the mass variations are necessary and a satellite-based observation capability is the only feasible approach for satisfying this requirement. The Gravity Recovery and Climate Experiment (GRACE) mission was conceived as a response to the need for such satellite-based measurements. The objective of the GRACE mission was to improve our understanding of the Earth by making pioneering measurements of the gravity signals associated with mass exchange within and between the Earth System components. The contributions enabled by the GRACE Mission data include investigations of change in global sea level,terrestrial water storage, continental aquifers, surface and deep ocean currents, polar ice mass and the mass redistribution associated with large earthquakes and post glacial rebound. The totality of these contributions to studies of Earth system dynamics under-scores both the role of the mass change as an essential climate variable and the importance of continuing the measurement record initiated by the GRACE mission.

This presentation will review the development of the time varying gravity measurements in the pre-GRACE era, summarize the contributions of the repeated gravity measurements during the GRACE mission, discuss the anticipated extension during the GRACE FO Mission and consider prospects for improved measurements from future missions.

Introductory Remarks

Hunting the Magnetic Field
Speaker: Lisa Tauxe

The strength of the magnetic field is one of the fundamental properties of the Earth, and its behavior over time has implications in disparate fields as geodynamics of archaeology. Thermal remanent magnetization (TRM), has a quasi-linear relationship to the ambient magnetic field applied during cooling and can be reproduced in the laboratory, making absolute paleointensity estimates possible. TRM, of all the forms of remanent magnetization formed in nature, has the strongest theoretical basis thanks to the work of Neel (1949) and Thellier & Thellier (1959). 
Despite the simplicity of TRM theory for ideal, uniformly magnetized grains, there are many complications that make interpretation of paleointensity experimental data difficult. And there are clues in the present data base that things can go very wrong. For example, although we know that directions on the surface of the Earth are well explained by a simple geocentric axial dipole field model the intensity data for even the best studied lava flow (Hawaii, 1960) have estimates spanning the entire range on the surface of the Earth and even higher. We must do better!

Recent results from micromagnetic modeling, laboratory analogue experiments and new approaches to data selection and field sampling lead to the optimistic view that accurate estimates are achievable. In this lecture I will review where we are, how we got there and where we can go with paleointensity estimates.

The Tyranny of Small Scales – on Representing Soil Processes in Global Land Surface Models
Speaker: Dani Or  

A 100 years ago, Lewis Fry Richardson established numerical weather prediction highlighting the need for systematic representation of land surfaces and processes at scales relevant to climate. Modern global land surface models (LSM) have benefited from the rapid expansion of observational capabilities and availability of highly resolved hydrological and soil information, yet traditional parameterization and representation of soil hydrological processes remain rooted in small scales and have not adapted to the large scale challenge. LSMs requirements for more nuanced hydrological parameters, better representation of infiltration, evaporation and other surface fluxes are often addressed by ad-hoc approaches built on small-scale representation of near-surface processes. We will discuss some of key gaps in land surface parameterization including limitations of present pedotransfer functions and potential inconsistencies in representing important processes at the LSM grid scale such as infiltration and surface evaporation. Equally important is the need to move beyond using small-scale distributed blueprints and heed the call of Dooge and Klemes to skip spatial scales in the pursuit of mega-laws. Several approaches offer a promise such as: Budyko’s aridity, catchment rainfall-runoff and effective infiltration, and evaporation complementary relation. These concepts were conceived for catchment scale processes, yet they remain incompatible with space and time constraints of modern LSMs. Advancing soil and hydrology process representation in LSMs would require a new generation of scale-informed land surface parametrization and the development of concepts that bypass the prohibitive small-scale filter.

AGU will present and pay tribute to the 2018 Union Prize Recipients, Awardees, Fellows and Medalists.

Evolving Data-driven Science: the Unprecedented Coherence of Big Data, HPC, and Informatics, and Crossing the Next Chasms
Speaker: Benjamin James Kingston Evans

As we approach the AGU Centenary, we celebrate the successes of data-driven science whilst looking anxiously at the future, with consideration of hardware software, workflow and interconnectedness that need further attention.

The colocation of scientific datasets with HPC/cloud compute has successfully demonstrated the overall supercharging of our research productivity. Over time we questioned whether to “bring data to the compute”, or “compute to the data” and considered and reconsidered the benefits, weaknesses and challenges both technically and socially. The gap between how large volume data and longtail data are managed is steadily closing, and the standards for interoperability and ability for connectivity between scientific fields have been slowly maturing. In many cases transdisciplinary science is now a reality.

However, computing technology is no longer advancing according to Moore’s law (and equivalents) and is evolving in unexpected ways. For some major computational software codes, these technology changes are forcing us to reconsider the development strategy, how to transition existing code to both address the needs of scientific improvements in capability, while at the same time improving the ability to adjust to changes in the underlying technical infrastructure. In doing so, some old assumptions of data precision and reproducibility are being reconsidered. Quantum computing is now on the horizon which will mean further consideration of software and data access mechanisms.

Currently, for data management, despite the apparent value and opportunity, the demands on high quality datasets that can be used for new data-driven methods are testing the funding/business case and overall value proposition for celebrated open data and its FAIRness. Powerful new technologies such as AI and deep learning have a voracious appetite for big data and much stronger (and unappreciated) requirements around quality of data, information management, connectivity and persistence. These new technologies are evolving at the same time as the ubiquitous IOT, fog computing, and blockchain pipelines have emerged creating even more complexity and potentially hypercoherence issues.

In this talk I will discuss the journey so far in data-intensive computational science, and consider the chasms we have yet to cross.

Scientific Discipline: Ocean Sciences

Introductory Remarks

Larval Odyssey and Marine Population Connectivity, Now and Tomorrow
Speaker: Claire B Paris

Most marine organisms begin their lives as planktonic larvae. They disperse into the pelagic environment where they develop, until they are competent to recruit to the adult population. Our work in the past decades has revealed a surprising fact about these microscopic larvae. They are not passively advected in ocean currents; instead, they control their transport through vertical migration and oriented swimming behaviors as they interact with the environment and respond to the cues it holds. Reef fish larvae make decisions on how to move based on the presence of external cues over a range of spatial scales — from Earth’s magnetic field, to celestial compass, from infochemicals, particularly the dimethyl sulfide produced in large quantities by corals and benthic algae, to reef sounds. Tracing their complex planktonic journey from the birthplace to the recruitment habitat has led to the paradigm of connectivity that plays a fundamental role on marine populations' structure and resilience. When this behaviorally mediated swimming is integrated in state-of-the-art biophysical models of larval transport, local retention and overall settlement success increase. The complex behavioral responses of larvae to their sensory environment is critical to our understanding of dispersal and population connectivity.

If we alter the pelagic habitat in ways that interrupts the larval “migration” process by which they find their way home, those larvae will miss their connections and/or will not survive their journey. Yet marine pollution from oil spills and massive use of chemical dispersants as emergency response alters the pelagic habitat in addition to the rapid changes in temperature due to climatic conditions. As our quest for oil reservoirs expands worldwide to ultra-deep waters and sensitive fisheries areas, we need to re-evaluate our impact on the planktonic larvae and population connectivity.

Major Science from Minor Planets: Discoveries of the Dawn Mission to Vesta and Ceres
Speaker: Carol A Raymond

NASA’s Dawn mission to explore the two largest bodies in the main asteroid belt, Vesta and Ceres, was conceived to investigate processes and conditions occurring at the dawn of our solar system. It met that goal by mapping the surfaces of these two relict protoplanets with imaging, visible, near-infrared, gamma ray and neutron spectra, and measuring gravity and topography to probe their interiors. Prior to Dawn, telescopic observations showed Vesta’s reflectance spectrum matched basaltic achondrite meteorites and its density (~3460 kg/m³) suggested it formed dry and hot. Ceres reflectance spectrum showed similarity to aqueously altered primitive carbonaceous chondrites, and its density of ~ 2100 kg/m³ and shape implied significant water content and mass differentiation in its interior. Understanding why these planetary neighbors evolved so differently motivated the mission. Dawn’s data confirmed that Vesta experienced igneous differentiation, implying it formed within 1.5 m.y. of the first solar system solids while live Al²⁶ was abundant, and that it accreted from volatile-depleted material in the inner solar system. Dawn revealed Ceres to be a chemically-evolved, geologically-active body, with ongoing brine-driven cryovolcanic processes erupting carbonate-rich magmas. Evidence for pervasive aqueous alteration and ice-rock fractionation inferred from Dawn’s data indicates that Ceres formed early enough for Al²⁶ to drive ice melting, forming a subsurface ocean, but moderation of its internal temperature by water prevented silicate melting. Ubiquitous ammoniated clays on Ceres’ surface indicate it formed in the outer solar system, while the discovery of organics on Ceres raises questions of their origin and evolution within the body. Post-Dawn, the leading theory is that Ceres formed in the giant planets region, as one of a class of large planetesimals predicted by recent accretion models, prior to implantation into the main belt due to giant planet accretion and/or migration. Understanding how Vesta and Ceres formed and evolved provides important constraints on the accretion, differentiation, and geologic and geophysical evolution of the diverse bodies of our solar system.

Part of this work was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under contract to NASA.

Infrared Eyes: Turning Darkness to Light Through the Solar System
Speaker: Philip R Christensen 

Thermal infrared observations have made significant contributions to planetary science over the past 50 years. Infrared spectroscopy has shed light on the composition of planetary surfaces and atmospheres, and thermal radiometry has provided great detail on the physical properties of planetary regoliths and their formation processes. Infrared instruments have been on virtually every planetary spacecraft, and these instruments have improved steadily over the past three decades. A great deal has been learned about the geology of Mars from a suite of thermal infrared instruments beginning with Mariner 6/7/9 and Viking, and continuing through Mars Global Surveyor, the Mars Exploration Rovers, and Mars Odyssey. Derivatives of these instruments are approaching the asteroid Bennu on OSIRIS-Rex, and are being developed for the UAE Hope Mars mission, the Europa Clipper, and the Lucy Trojan asteroid tour mission. This talk will discuss some of the major discoveries that have come from these data and what we’ve learned from them about planetary processes and geology over the past 40 years – and will provide a few thoughts on the future of planetary exploration using thermal infrared observations.

Introductory Remarks

Our Heliosphere's Interstellar Interaction: Observations and Discoveries
Speaker: David J McComas

The solar wind and its embedded magnetic field flow outward from the sun in all directions, inflating a bubble in the local interstellar medium called the heliosphere. Prior to 2004, there were very few direct observations of the interaction of the heliosphere and local interstellar medium and our knowledge of these regions was largely theoretical. Then, 2004 and 2007 the Voyager 1 and 2 spacecraft crossed the heliosphere’s termination shock and in 2012, Voyager 1 went on to cross the heliopause and entered interstellar space. IBEX – the Interstellar Boundary Explorer – launched in 2008, and has been returning 3-D global observations of ion distributions in the heliosheath and beyond via charge exchange Energetic Neutral Atoms (ENAs), continuously since then. These sets of observations are highly complementary with the Voyagers providing detailed in situ measurements along their two trajectories and IBEX returning all-sky maps of ENAs with energies from <0.1 to ~6 keV. Over the past decade and a half, these observations have led to numerous discoveries and “firsts” and a true scientific revolution in our understanding of the outer heliosphere and its interstellar interaction. With the continuation of the Voyagers and IBEX, and NASA’s recent selection of the Interstellar Mapping and Acceleration Probe (IMAP) to launch in 2024, the heliophysics community can look forward to many more years of outstanding new observations and innovative science. Aptly named for Gene Parker, who provided some of the earliest and most fundamental ideas about the heliosphere and its interstellar interaction, this Parker Lecture summarizes some of the biggest discoveries and most intriguing mysteries of this fascinating region that surround our home in space.

For three decades, photographer James Balog has broken new conceptual and artistic ground on one of the most important issues of our era: human modification of our planet’s natural systems. He and his Extreme Ice Survey team are featured in the 2012 internationally acclaimed, Emmy award-winning documentary Chasing Ice and in the PBS/NOVA special, Extreme Ice. He is the author of ICE: Portraits of Vanishing Glaciers and seven other books. His photos have been extensively published in major magazines, including National Geographic, and exhibited at museums and galleries worldwide. His new film The Human Element, is an innovative—perhaps even revolutionary— look at how humanity interacts with earth, air, fire and water. The film will be released later this year.

This new Friday plenary will mark the official start of AGU’s Centennial. The program will feature a series of short presentations developed by AGU’s Council and representing all 25 AGU sections, covering topics from Earth’s core to the solar system and beyond, and reaching to new transdisciplinary topics, societal issues, education, culture, and more. Rapid-fire presentations will showcase the discoveries, innovations, connections, and solutions that have led to the current richness of the Earth and space sciences today and predict how the science and its importance and impacts will grow through this century. The session will also highlight what’s to come in the Centennial year.
