DESCRIPTION:FROM MINERAL INTERFACES TO RESOURCE ECOSYSTEMS: OPPORTUNITIES 
 AND\nCHALLENGES FOR ALTERNATIVE CRITICAL MINERAL RESOURCES\n\nABSTRACT:\nG
 rowing demand for critical minerals is driving interest in resource\nstrea
 ms that extend beyond conventional high-grade ores\, including\nmine and i
 ndustrial wastes\, low-grade geological materials\, secondary\nresources\,
  and biologically accumulated metals. These alternative\nresources could d
 iversify domestic supply while reducing waste and\nenvironmental impacts\,
  but they also present a fundamental scientific\nchallenge: valuable eleme
 nts often occur at low concentrations\, in\nheterogeneous matrices\, and i
 n chemical forms that are poorly\nunderstood and difficult to selectively 
 recover.\nThis talk will examine how molecular- and mineral-scale understa
 nding\nof element speciation\, mineral-water interfacial reactions\, and\n
 coupled dissolution\, transformation\, and separation processes can\ninfor
 m the development of critical mineral resources. Drawing from\nrecent work
  on unconventional resources from our group\, I will\nhighlight how advanc
 ed spectroscopy and microscopy\, geochemical\nexperiments\, and process-or
 iented studies can connect fundamental\nunderstanding of where critical el
 ements reside and how they are bound\nwith strategies for selective mobili
 zation\, separation\, and recovery\nfrom complex\, low-grade materials.\nT
 he discussion will then broaden from individual extraction processes\nto t
 he resource ecosystems in which they operate. Realizing the\npotential of 
 alternative resources requires integrating geochemistry\nand separation sc
 ience with resource characterization\, data and\npredictive tools\, proces
 sing infrastructure\, environmental\nperformance\, regional supply chains\
 , and workforce development. This\nsystems-to-ecosystems perspective provi
 des a framework for identifying\nwhere fundamental interfacial science can
  have the greatest impact on\ntranslating unconventional resources into se
 cure\, sustainable\, and\neconomically viable mineral supply chains.\n\nBI
 O:\nDr. Yuanzhi Tang is the Georgia Power Professor in the School of Earth
 \nand Atmospheric Sciences and the School of Civil and Environmental\nEngi
 neering\, and the Executive Director of the Strategic Energy\nInstitute an
 d at Georgia Tech. She leads interdisciplinary efforts\nspanning elemental

 us on connecting fundamental research to\nreal-world impact. She is also t
 he founding director of the Center for\nCritical Mineral Solutions and has
  helped build regional and\ninternational partnerships around sustainable 
 critical mineral supply\nchains.\nDr. Tang’s research focuses on molecul
 ar scale processes at\nmineral-water interfaces and their applications in 
 resource recovery\,\nnutrient cycling\, energy materials\, and circular re
 source systems. Her\nwork integrates advanced spectroscopy\, microscopy\,

DESCRIPTION:THE ROLE OF RHEOLOGY IN GOVERNING ICE SHEET DYNAMICS \n\n \n
  \nABSTRACT:\nMass loss from the Antarctic Ice Sheet largely occurs due t
 o the\nviscous ice flow of glaciers from the interior of ice sheets toward
 s\nthe ocean. The rate of flow to the ocean is governed by ice viscosity\,
 \nwhich in turn depends on microphysical and macrophysical processes.\nWhi
 le increasing amounts of evidence suggest that ice viscosity varies\nsigni
 ficantly in space and time in the Antarctic Ice Sheet\, current\nice sheet
  models treat ice viscosity as a fixed\, empirically-derived\nvalue. In th
 is talk\, I first explore the implications of neglecting\nthis complexity 
 in ice viscosity. I demonstrate using simple\,\ntheoretical models that ic
 e rheology may play a significant role in\ngoverning transient ice sheet d
 ynamics and may alter the stability\nportrait of marine ice sheets. I furt
 her show that in the current\nconfiguration of the Antarctic Ice Sheet\, r
 heology likely plays a\nsubstantial role in governing the force balance\, 
 thereby setting the\nflow speed. I then present a bulk parameterization me
 thod for\nincorporating ice crystal-scale processes into a model for ice\n
 viscosity and demonstrate that this provides a way of parameterizing\nthe 
 effect of varying flow conditions on future ice sheet behavior.\nFinally\,
  I then show first steps towards a formal multi-scale ice\nviscosity model
  implemented using a neural emulator of an ice\nmicrophysics model\, which
  provides a path forward for formally\nrepresenting crystal-scale variabil
 ity in ice viscosity in large-scale\nice sheet models.\n\nHost: Dougal Han

DESCRIPTION:THE COMPOSITIONAL DIVERSITY OF ROCKY EXOPLANETS: CONSEQUENCES 
 FOR\nEVOLUTION\, TECTONICS\, AND HABITABILITY\n\nThousands of exoplanets h
 ave been discovered over the last 30 years\ncovering a wide range of sizes
 \, compositions\, interior structures\, and\nstellar radiation environment
 s. Many of these planets are likely rocky\nbased on their bulk density. Th
 e variation in rock forming elements\nseen in stars show\, to first order\
 , that rocky exoplanets could span a\nwide range of mantle mineralogies\, 
 from Earth-like olivine-pyroxene\nmixtures to nearly pure olivine or pure 
 pyroxene mantles. Combinations\nof pyroxene and quartz or olivine and peri
 clase are also possible.\nSuch compositional variation could have profound
  consequences for the\ntectonics\, evolution\, and habitability of rocky e
 xoplanets. I will\ndiscuss how rocky planet compositional variations can i
 nfluence their\nlong-term thermal evolution and ability to promote habitab
 le surface\nenvironments through volcanism and weathering. I will further 
 show how\nplanet composition can influence whether planets operate in a\ns
 tagnant-lid or plate-tectonic regime. Planets with sub-equal mixtures\nof 
 two or more minerals can more readily generate the weak\nlithospheric shea
 r zones required for plate tectonics by mineral phase\nmixing and grain si
 ze reduction. Finally\, I will discuss how models of\nexoplanet geological
  evolution are critical for interpreting\nastronomical observations.  \n\

DESCRIPTION:MAPPING THE GLOBAL SEAFLOOR USING SATELLITES AND SHIPS: RECENT
 \nIMPROVEMENTS FROM SWOT GRAVITY USING MACHINE LEARNING\n\nVariations in E
 arth’s gravity field create broad bumps and dips in\nthe ocean surface t
 hat mirror the mass distribution of seafloor\nfeatures such as ridges\, se
 amounts\, and trenches. This relationship\nenables scientists to infer sea
 floor depth from satellite altimetry\,\nthough fundamental physics limits 
 the achievable resolution in the\ndeep ocean to about 3–5 km. Over sever
 al decades\, successive\naltimeter missions have progressively refined glo
 bal seafloor maps\,\nand the new SWOT mission now provides the most precis
 e marine gravity\nmeasurements to date. In this study\, five research grou
 ps applied\nmachine learning to merge SWOT gravity data with ship sounding
 s\,\nproducing consistent global bathymetry maps that are 23–46% more\na
 ccurate than traditional approaches. The greatest gains are in\nresolving 
 shallow seamounts and deep trenches\, improving our ability\nto study ocea
 n circulation\, plate tectonics\, and geologic hazards\,\nwhile advancing 
 the goals of the international Seabed 2030 initiative\nto map the entire o
 cean floor by 2030.\n\nHost: Roger Michaelides\n\n_EEPS Colloquia are made

DESCRIPTION:GLACIALLY-DRIVEN CHANGES IN SUBMARINE HYDROTHERMAL ACTIVITY\n\
 n \n \n \n \nLand-based volcanic systems and geophysical modelling of 
 mid-ocean\nridges suggest that submarine volcanic activity may be influenc
 ed by\nglacially driven changes in sea level. Is there evidence for\nglaci
 ally-paced variation in submarine hydrothermal circulation? In\nthis talk\
 , I will present a suite of hydrothermal iron flux records\nderived from m
 id-ocean ridge sediment cores and explore their\nimplications for marine i
 ron cycling\, iron delivery to Southern Ocean\nsurface waters\, and possib
 le driving mechanisms linking the climate\nsystem and the solid Earth on g
 lacial timescales. I will also\nelaborate on the utilization of constant f
 lux proxies\, the geochemical\ntools that enable reconstruction of hydroth
 ermal time series and other\npaleoceanographic flux records from sediments
  that have accumulated in\ncomplex bathymetric environments.\n\n \n\nHost
