Title: Geodesy at The Land Margins: Challenging yet Rewarding
Abstract: High precision space geodetic techniques have been widely used in measuring Earth changes due to slow or rapid processes. While they continue to provide important observations for a variety of geophysical studies, technical limitations have hampered their applicability in monitoring several key Earth processes in critical zones, such as tidal-timescale or shorter timescale variations of the outlet glaciers and mélange in the polar regions, as well as strain accumulation and release processes in the offshore portion of subduction zones. Continued development of terrestrial and marine geodetic techniques can overcome some of the difficulties and thus complement existing methods. However, they can be technically challenging. In this talk I will present several examples of space, terrestrial, and marine geodetic techniques in observing some key Earth processes at the marginal zones, including: 1) observing marine-terminating glacier and mélange motion in Greenland with terrestrial radar interferometry; 2) measuring subduction zone interface locking and transient events with GPS; and 3) shallow water seafloor motion and water level monitoring with a GPS spar-buoy.

What will we eat in a bigger, hotter and smarter world? Climate models show that global crop production will continue to decline due to drought, heat, and flooding. Meanwhile, the world’s population is expected to grow another 30 percent by midcentury. So how, really, will we feed nine billion people sustainably in the coming decades? Hear how Amanda Little spent three years traveling through a dozen countries and as many U.S. states in search of answers to that question.

Title: Probing Earth’s Shallow Crust with Space Geodesy
Abstract: Contemporary earthquake hazard models hinge on an understanding of how strain is distributed in the crust and the ability to precisely image the earthquake rupture. The development in these fields is driven by the newer generation of space geodetic tools. In this presentation, I’ll be focusing on the shallow most part of the Earth’s crust, and bridge the mechanisms of reduced shallow rupture (shallow slip deficit) with the widely distributed shallow faulting. I show that a large part of the shallow slip deficit is due to incomplete data coverage near the fault when combined with a regularized inversion, and thus the associated seismic hazard may have been underestimated. Thus, near-fault geodetic observations are indispensable to fully image large strike-slip events. I’ll then present our newest findings associated with the 2019 Ridgecrest earthquake sequence, where we found numerous previously unmapped strain concentrations (fractures) with an InSAR phase-gradient technique. Most fractures are displaced in the direction of tectonic stress (prograde), while a number of them are displaced in the opposite direction (retrograde). Our analysis shows that both types of fractures are caused by the stress change from the main rupture – prograde fractures are triggered slip while retrograde fractures are strain concentrations in a weak compliant fault zone. The different mechanisms can be understood if the shallow part of the faults are always critically stressed. And a major implication is that shallow tectonic strain is widely distributed in diffuse strike-slip areas like the Mojave shear zone, which also explains the larger deficit in the shallow earthquake ruptures near Ridgecrest.

Title: Sediment Dispersal Dynamics at a Tectonically Active River Delta
Abstract: River deltas build land in coastal regions mainly by the process of lobe avulsion. Through multiple avulsion cycles, deltas grow basinward. However, many studies on delta building often assume time continuous subsidence. In nature, deltas residing at active margins are affected by discrete subsidence events. These events can drive adjustments in delta morphology, avulsion dynamics, and development of stratigraphy. To explore such impacts, detailed measurements of delta and basin morphology, spanning one and half centuries, were collected using remote sensing and field surveys, from the Selenga River delta, residing along the active Baikal Rift Zone, Russia. At the Selenga Delta, over multiple millennia, earthquake associated tectonic subsidence events lower portions of the topset below mean lake surface elevation, creating shallow embayments near the coast. We find that Selenga Delta lobe avulsion is triggered predominately by the newly created accommodation from the partially subsided lobe. Our results also indicate that gravel is arrested near the coast on the subaerial delta, while only mud is transported to the basin, as confirmed by core data. As active rift basins are perennial sediment sinks, impacts of discrete subsidence events on stratigraphy at Lake Baikal could be used to inform more generalized basin-evolution models. Leveraging the data and findings derived from the Selenga Delta, we also develop a practical method, based on graph theory, that uses remotely sensed variables to predict partitioning of water discharge and total sediment discharge in distributary coastal networks. This method have broad modeling applications for large-scale delta systems worldwide, where field data may be limited.

A Jurassic Lost World Revealed; Spectacular Images of the Base of the Louann Salt Reveal a Drowned Topography
Frank J Peel and Gillian M Apps
We care how giant evaporites were deposited because they tend to be formed at times of global crisis, such as extreme climate events, supercontinent breakup, oceanographic upheaval, etc. Understanding these critical times helps us to understand how the global geosystem works.
But for giant salt deposits, the present is NOT the key to the past; there is no modern analog! Past workers have used modern salt basins as analogs to these giants of the past, but they are fundamentally different in scale and process.
Some salt deposits, such as the Zechstein, contain interbedded non-salt sediment layers that can reveal the paleogeography of the salt basin and the water depth, and show how those evaporites were deposited. But the Jurassic Louann Salt of the Gulf of Mexico is different; it contains no such layers, and there has been no obvious way to investigate the basin paleogeography.
As a result, there have been many uncertainties – was the basin shallow-water, or a deep marine basin? Was it deposited slowly, over millions of years, or extremely rapidly, over thousands of years? When salt deposition ended, was an exotic tectonic subsidence mechanism required to get to the depths seen in later sediments, or was it already a deep basin?
Now, for the first time, there is hard evidence that answers some of these questions. A unique seismic data set shows, in exquisite detail, the nature of the landscape on the floor of the basin on the eve of salt deposition. The data reveals beautiful images of a semi-arid pre-salt world, with wadis and rivers draining from rugged, mountainous highlands, flowing across what is now the bottom of the basin, into a large pre-salt lake in the middle of the basin. The mid-basin lake, which we have named Lake Jackson in honor of Martin Jackson, was deep; at least 750m within our data set, probably much deeper in the middle. The pre-salt lake margin was steep, with fault scarps that were eroded above lake level, and fan-deltas deposited below lake level. Water level in the lake lay about 1km below global sea level.
Flooding of this pre-salt world was rapid, possibly catastrophic, creating the Louann Sea, a body of water several km deep. The shallow-water depositional model for the Louann is disproved.
Combined with geochemical information, we can infer a depositional model in which the salt was precipitated in deep water, with evaporation matched by seawater influx. Deposition was extremely rapid, possibly the fastest documented episode of sustained sediment deposition known to science.
With this knowledge, we can now explain the post-salt evolution of the basin, and we can begin to constrain the nature of the pre-salt sediments within the basin, which remain untested and unknown.

Title: Multiproxy reconstructions of late Holocene coastal climate and extreme events
Abstract: The densely populated coastlines of the United States face unique natural hazards and are at the forefront of global change phenomena, and including sea level rise, rising global temperatures, changing storm frequency and intensity, and growing anthropogenic pressures. Adaptation to, and mitigation of, the impacts of these phenomena rely on extensive and accurate records of coastal stressors and an understanding of their secondary ecological effects. Instrumental data of physical and biological changes along the coast extend, at best, about 120 years and are usually much shorter. Thus, longer high-resolution records of coastal phenomena are essential to determine the potential range and return interval of storms, floods, droughts, and earthquakes. Multi-centennial to multi-millennial length tree-ring records are annually-resolved proxies for environmental change that fill these critical data gaps. These records ultimately improve coastal management and hazard planning, as well as detect and attribute trends in regional climate phenomena. Using climate field reconstructions, a network of subfossil ‘drowned’ forests and co-located sediment records, radiocarbon, and paleoecology studies I show how we can date and characterize both long term trends and punctuated extreme events along the northeast and northwestern coastlines of the United States.

Fleets of Autonomous Vehicles for Enhanced Geophysical Sensing:
The Role of Formation Control Systems
The development of autonomous vehicles has revolutionized geophysical and geochemical sensing. However, most of the current deployments employ such vehicles simply as individual platforms. Yet, many of the new emerging applications require deployment of a large fleet of unmanned vehicles moving collectively in a formation constrained to maintain a fixed geometric shape while maneuvering. This added complexity can be quite challenging for any geophysical data acquisition program, but it is particularly formidable for underwater platforms where GPS signals are unavailable and alternative localization strategies can be rather costly or inaccurate.
The advent of Formation Control Theory in recent years has provided a theoretical foundation for understanding and controlling formations and swarms through simple localized inter-vehicle exchange of information. In this talk, we present recent results from an analytical and numerical feasibility study to explore applicability of formation control theory to geophysical data acquisition. Specifically, we consider the problem of conducting a streamer-free mobile marine seismic survey. To this end, we examine a typical marine seismic survey layout, focus on the possibility of replacing the cable-linked receivers by sensor-carrying autonomous vehicles, and address the questions of inter-vehicle sensing and control algorithms required to robustly maintain the desired acquisition geometry while maneuvering. We present numerical simulation results to demonstrate the feasibility of this approach and to address the resulting tradeoff between cost and complexity on the one hand and robustness in the face of potential sensor failures on the other hand.

Title: Imposing physics-based sparsity in large scale inversion algorithms
Abstract: Inversion algorithms provide a way to estimate physical properties of an unknown object from a data set. There are numerous applications for these algorithms in medical imaging, computational seismology, target identification, electromagnetic inverse scattering, and subsurface imaging. However, these problems are nonlinear and ill-posed. Exact numerical algorithms are limited to small scale problems in terms of wavelength. With the increasing computational power, inversion techniques are becoming more efficient for realistic and large-scale problems. To tackle the challenges above, one uses some physical approximations. Still, these problems are often formulated as iterative schemes and contain large data sets. An a priori knowledge of the data is essential to address these algorithms correctly. This utilization must rely on a proper understanding of the wave propagation physics and physics-based signal processing.
In this talk, we present a physics-based sparse data approach for large scale inversion algorithms. Recent developments in wave technology have enabled us to gather reliable data, which provides a high degree of spatial resolution of the propagation environment. We present both forward and inverse models including a derivation of analytical models for the measured data. We show a direct relationship between the data and specific targets. This relation enables an a-priori sparse representation of the inverse problem, which leads to fast, robust, and efficient algorithms. We demonstrate these features with several numerical examples.

As microbes utilize this carbon source, they produce greenhouse gasses (GHGs; CO2 and CH4) that can be emitted to the atmosphere and act as a positive feedback during future global temperature increases. While the permafrost carbon feedback has received much attention in the literature, little is known about the multiphase flow properties and the temperature dependence of microbial GHG production rates in thawing permafrost, both of which are essential for predicting GHG emissions from permafrost in the future. Flow experiments of synthetic and natural permafrost specimens under frozen conditions and incubations of permafrost samples are being performed to better understand the effective and relative permeabilities and GHG production rates of thawing permafrost soils. These data will be integral in providing new source terms for permafrost and global carbon models. |

However, different processes can lead to the formation of chemical identical molecules. This makes answering a number of scientific questions challenging. One example is distinguishing between biotic and abiotic molecules, hence hindering life detection on early Earth but especially on other planetary bodies, such as on Mars, Titan, Enceladus and on meteorites where organics have been detected. Moreover, tracing molecules as they move through the environment can be demanding, yet is essential in studying the flow of organic molecules as well as correlating pollutants with their source. Novel tools to address these challenges are currently being developed. Especially, the emerging field of position-specific isotope analysis is beginning to grant access to the unique intramolecular carbon (13C/12C) isotope fingerprint preserved in complex molecules. This fingerprint can be applied in various scientific disciplines, ranging from forensics to exobiology, geo- and environmental sciences, including geo health. Nuclear magnetic resonance spectroscopy (NMR) has the potential to become a key player in this research area, as it allows the analysis of organics within complex mixtures, all without the need to fragment the molecule into single carbon units or the combustion of the molecule of interest. We have been developing several NMR tools that allow us to investigate the intramolecular carbon isotope distribution within various molecule classes and to test the central hypothesis that the position-specific carbon isotope distribution within complex organics depends on a molecule’s source and formation history. |
