Title:
Physical limnology

Description:
The research of physical limnology has been scarce compared with biochemical and ecology studies in several Mexican lakes.

The main purpose is to bring together diverse studies, from research projects as preliminary and published, focused on studies (water quality and biota) related to physical processes (wind driven currents, thermal structure, internal waves, mixing processes, transport, etc.) in lakes.

Also, it is to outline that tropical limnology is poorly understand compared with temperate limnology paradigms that are not observed in tropical lakes (such as the concept of thermocline).

In this session we are happy to cordially invite all scientist and students to participate in the conference and share the latest interdisciplinary issues about observational data, experimental,
theory and numerical modeling, in different world lakes.

Title:
Digital media on Earth Science communication, outreach, and education: resilience and adaptation in our new normal

Description:
In the academy, a significant portion of time and resources is invested in communicating research topics. However, the physical distancing measures present a challenge to continue with conventional communication activities. In this special session, we provide a space for sharing and critically reflect on how Earth Science communication, outreach, and education has adapted to the new reality through digital media, including but not limited to podcasts, blogs, video-blogs, online classes, online events, and online communities.

We welcome communicators, research teams, institutions, students, professors, and collectives that are involved in digital geoscience education, communication, and/or outreach and are interested in sharing the best practices in the field and creating links that promote collaborations among participants. As a result, we expect that those dialogues will help strengthen geoscience communication in Mexico and promote resiliency in the face of our new reality.

Title:
Recent advances in numerical, experimental or statistical modelling approaches for wind and marine renewable energy

Description:
The general focus of this special session is on numerical modelling and data acquisition for wind and marine renewable energy resource analysis. Studies based on numerical, experimental, or statistical models applied to renewable energy device development and performance analysis are also welcome.

This year, the session will focus on recent advances on microscale and mesoscale models, as well as meso-microscale model coupling, that improve wind and marine renewable energy resource characterization. The session not only seeks to present numerical modelling results, but also developments of remote sensing and in-situ measurement techniques, that in turn can help evaluate the numerical models and set-up improved boundary and initial input conditions for numerical weather prediction (NWP), numerical hydrodynamic prediction (NHP), and computational fluid dynamics (CFD) models. We invite contributions on novel numerical or data science algorithms that may reduce uncertainty in wind energy resource characterization. We also invite individual contributions or contributions in the “meeting-within-a-meeting” format, which may focus on particular research, development, or technology innovation projects (such as, for example, project "MEWA" or the Mexican Wind Atlas “WAM”), from wind atlas development to technological and numerical Innovations, from local to regional scales. We also welcome any other discovery or solution-based studies, either on wind energy or other renewable energy or energy storage and transport systems, that may have an impact on wind energy resource characterization.

Title:
The IUGG-Mexico in the current scientific collaboration on natural phenomena and its effects on disaster resilience

Description:
The International Union of Geodesy and Geophysics (IUGG) is a non-governmental scientific organization comprised by 8 associations, dedicated to the study of the cryospheric sciences, geodesy, geomagnetism and aeronomy, hydrological sciences, meteorology and atmospheric sciences, physical sciences of the oceans, seismology and physics of the earth’s interior, and volcanology and chemistry of the earth’s interior. The IUGG-Mexico National Committee has among other objectives, the promotion of studies for the disaster prevention and mitigation, as well as the encouragement for the exchange of state-of-the-art knowledge with top-level scientists in geosciences, strengthening multidisciplinary and interdisciplinary cooperation in projects among the associations and with all international scientific organizations. The collaboration in these geoscientific areas becomes essential not only for the assessment of natural hazards and risks, but also as a basis for improving the resilience to such phenomena.

In this session there will be welcome those works related to proposals for multi-, inter- and trans-disciplinary coordination in these areas; likewise, those related to the possible current and future scopes of geoscientific research for the benefit of society. We invite to submit inter- and multi-disciplinary works on emergency situations and their possible effects; collaborative projects related to COVID19 (seismic noise, oceanic and atmospheric environmental effects, surface water and groundwater, geomagnetism and space weather, respiratory protection by volcanic ash, among others) and its possible benefits; international collaborations on climate change and interdisciplinary models for evaluating natural hazards and risks. In the same way, the participation of presentations of international collaborations for the improvement of scientific policies and financing of science is encouraged.

In the session there are proposed four invited conferences given by internationally recognized scientists belonging to the IUGG. Given the current circumstances, it is proposed that this session be conducted 100% virtual by teleconference, increasing, among other advantages, the possible scope of the session.

Title:
Geosciences in society: education, outreach and dissemination

Description:
The development of Geosciences in our country has been increasing exponentially in the last decades. This is due to the scientific and technical interest of geoscientists. Learning about the dynamic of Earth and the processes which formed the enormous geological wealth of México, is and will always be, the purpose of Geosciences. Geology has extended its horizons and now it takes into account other sciences such as Mathematics, Chemistry, Physics, Biology among others.

Geology's diversity, has favored the development of Mexican scientists. They have become more capable to understand Earth's phenomena surrounding them. An outstanding understanding, assimilation and dissemination of Earth Sciences is vital. Researchers must work on finding easier ways for teaching science for everybody's comprehension. A good researcher must have interacting skills and being committed to his work.

The objectives of this session are mainly the exchange of teaching techniques and innovative tools in the the process of education, outreach and dissemination of Earth Sciences in our country. These techniques might include tasks able to be managed inside and outside classrooms, they should be reachable everywhere and free for the society. The session accepts works related to Earth Sciences' outreach and dissemination, curriculums, impact and social retribution, and new teaching methods.

Title:
Remote sensing in geosciences - research supported by Earth observing technologies

Description:
A big part of research on geosciences (geology, oceanography, astronomy, etc.) is possible thanks to our technical ability to measure things from afar. Development of remote sensing —or teledetection— technology, has facilitated the study regions of the Earth that were otherwise inhospitable or inaccessible, as well as the observation of large portions of its surface in a relatively short period of time. Even though it is based on primitive principles, like eyesight or animal echolocation, teledetection has reached a point in its development through which it is now possible, for example, to register the sea surface temperature of the entire Gulf of Mexico within a few minutes or the 3D relief of a whole pre-Hispanic temple with millimetric precision. Sensors mounted on satellites, on land stations, and on manned (or unmanned) aerial, maritime or submarine vehicles, record a large number of acoustic or radiometric parameters that are readily transformed into geophysical variables of interest, like significant wave height, Chlorophyll concentration, tectonic subsidence, etc. For this Special Session, we invite presentations on geoscience assisted by remote sensing technologies: lidars and echosounders, radars and radiometers, spectrometers and radio scatterometers, etc., spaceborne, airborne or land-based. This session provides continuity to others presented in former editions of the MGU Annual Meeting, like "Emergent Schemes for Earth Observation" and "Development and implementation of technology for scientific research on the seas and coasts of Mexico".

Title:
Application of remote sensing to coastal regions

Description:
The development and improvement of high-resolution remote sensing are allowing for higher applications to coastal areas. For example, advances in the high resolution include a sub-kilometer resolution from the Visible Infrared Imaging Radiometer Suite (VIIRS), as well as improvements in removing land contamination from passive microwave instruments. They allow coastal monitoring with a spatial and temporal resolution that has not been fully exploited or validated. Also, more extended temporal availability and new direct or derived measurements allow a more holistic spatially-explicit study of these regions. In this session, we focus on the critical coastal seas of the world’s oceans. As these are areas of tremendous economic importance, monitoring, and understanding possible long-term changes in ocean biophysical parameters and their impacts is critical.

Sea surveys conducted by long-term monitoring programs, such as the California Cooperative Oceanic Fisheries Investigations (CalCOFI), the Mexican Investigations of the California Current (known in Spanish as IMECOCAL), and the Gulf of Mexico Research Consortium (known in Spanish as CiGoM), provide unique opportunities for validation in a coastal regime. However, other monitoring programs in other coastal regions are as valuable to validate the use of remote sensing in coastal areas.

Presentations that apply remote sensing to identify and validate the meso/submesoscale variability in coastal regions are especially sought. This topic includes validation from the seasonal to interannual time scales. Applications that use high-resolution models are also encouraged.

Ten years after the El Mayor-Cucapah earthquake (Mw 7.2)

Description:
The El Mayor-Cucapah earthquake (Mw 7.2) occurred on April 4, 2010 in the Mexicali Valley, near the border between California USA and Baja California, Mexico. This earthquake had a great impact on different areas of society, as well as on authorities and academia.

The objective of this session is to provide a space for analysis on recent research advances in the areas of Earth Sciences, Engineering and risk management; as well as the dialogue and exchange of experiences on the scientific challenges faced during and after the earthquake.

Finally, we seek to reflect on what has changed in these 10 years? What have we learned? Are we ready for a next big earthquake in Baja California? Are Mexicali and its valley resilient?

Geoscientists from the present inspiring the future ones: an online session for everyone

Description:
Until recent years, geosciences were unknown for most of the people and of little interest compared to other areas of knowledge. As history itself tells it, humankind has always wanted to understand their environment. Consequently, the study of Earth sciences has been more relevant given that natural phenomena that have destroyed entire cities or by human origin incidents associated with the Earth. The future, as we have already seen, demands experts who will attend globals issues, which are directly related to processes in our planet. This session intends to present geosciences to the non-specialist public in a plain language considering the main ideas. The fundamental idea is to develop an online session for UGM members and non-members who can access from their institutions and communities all over the country during labour hours.

Title:
Regional climate modelling and CORDEX

Description:
Regional climate models are a powerful tool to improve the knowledge of the physical, chemical and dynamical processes that regulate the weather and climate and their possible changes. Computational growth has favoured the development of a large number of global and regional climate models. Multi-institutional projects for regional climate model intercomparison such as CORDEX (Coordinated Regional Downscaling Experiment) have produce regional climate models outputs at 50 and 25 km for several domains in the world, and in Europe at 10 km; CORDEX is currently planning simulations at even finer resolution forced with global models for a historical period and for future emission scenarios. This information is available to the scientific community and it is relevant for regional process studies, for the evaluation of the possible impacts of climate change in different regions, and for decision-making and adaptation.

In this session, we are convening abstracts (in english or spanish) on:
1) Evaluation of regional climate models for different physical processes and impacts in various regions of the world, with particular emphasis on the CORDEX framework.
2) Studies of different physical processes relevant at regional scale under current and future conditions using regional climate models (dynamical, statistical, or hybrid downscaling).
3) Studies at local scale using convective permitting models.
4) VIA (vulnerability, impacts and adaptation) studies under climate change conditions.

Title:
Coastal resilience

Description:
Coastal Resilience is the capacity of any socio-ecological system (SES) to recover or reach a new equilibrium, at different rates and scales, following the impact of environmental or socio-economic stressors or shocks, while maintaining its functionality and services. Its study is highly complex given that SES are sensible to anthropogenic activities (land use changes, pollution, exploitation and economic activities), the effects of climate change (sea level rise and increased temperature), as well as the occurrence of extreme meteorological and seismic events. In this session we invite the submission of abstracts related to coastal resilience and any aspects that make its evaluation possible (stressors, shocks, thresholds, interactions, tendencies,...). The presentations can be theoretical, experimental, numerical, or based on field data, from uni-, multi-, inter- or transdisciplinary approaches.

Title:
Urban hydrographic analysis – a methodological proposal to mitigate flood damage in urban areas

Description:
Currently, urban areas suffer, year after year, numerous damages due to flooding in the rainy season. Unfortunately, and as a consequence of climate change, the rainy season will be highlighted by intense local rains with short durations, that is to say, that in a short time a lot of water will precipitate, so the areas that were already flooded, now more will flood and at the same time new areas will appear with this danger.

Currently there is no work on the origin of the water that reaches flood risk areas. The activities that are carried out are focused on cleaning and dusting the hydraulic areas of the drains, channels, streams or rivers that cross the urban area, from which tons of garbage, organic matter and sediment are obtained. However, due to urban growth, these hydraulic areas have already been exceeded by the volume of water that runs down the streets.

The Urban Hydrographic Analysis course, a proposal to reduce flood damage in urban areas, serves to train and give students tools to help them identify the origin of the water and the direction that it follows along each of its streets in the areas. urban, until its discharge, which can be in a river bed or a flood zone. With the identification of the origin and the direction of the flow through the streets, the student will be able to locate the places where he can propose some deviation, caused flood or other work, so that he does not reach the areas in danger of flooding.

The student during this course will learn a new methodology for hydrographic analysis in an urban area and will apply it in areas at risk of flooding in their locality, to try to find sites to develop works or preventive strategies and develop preventive programs.

Marine spatial planning – guidance on concepts and good practices

Description:
This course will focus on fundamental aspects of Marine Spatial Planning (MSP) and will be divided into two parts. In the first part, we will present definitions and terminology that will help explain what we understand by MSP, what are its benefits, and what results one may expect from a good Marine Spatial Plan. In the second part, we will discuss the 10 steps of the workflow that a good MSP needs to follow, according to Ehler and Douvere (2009). Following these steps will ensure that we achieve a successful MSP. We will also discuss what has worked and what has not worked Marine Spatial Planning, using case studies from around the world. The course consists of a MSP development guide that is useful when one has little time, little funding, little information, or other resources. This guide is also useful when we do not have a background in management or administration. For those with a Science or Engineering background, it is a priceless first approach to the subject, so that we do not need to learn “on the job”. A final test will be applied at the end of the course.

Title:
Technical aspects of design and manufacture of mesocosm to evaluate benthic fluxes in sediments

Description:
This course will focus on fundamental aspects of design, construction, and performance of different mesocosm or incubation chambers used to evaluate benthic fluxes in sediments. Theoretical, technical, and practical concepts of the implementation of mesocosms and its application as a resource to study and evaluate benthic processes in sediments will be outlined. Some considerations respect to water volume, stirring rate, portability, and sturdiness will be presented.

Relevant theoretical aspects involving benthic fluxes calculations and its implementation to study not only nutrient cycling, but also organic pollutants, or metabolic dynamics of seagrasses will be explained.

This course is mainly an introductory course to the mesocosm design and construction. Information on materials, suppliers, workshops with contact information, and practical advice on how, when, and where incubation techniques could supply answers to the evaluation of benthic processes in sediments from different ecosystems such as lakes, rivers, or coastal lagoons will be discussed.

It is an excellent opportunity for those interested in supply evidence of the importance of coastal marine ecosystems not only as reservoirs but also as highly dynamic ecosystems. Of course some practical examples will be presented and a simple prototype will be shown and if some of you are interested we could design and built an incubation system according to your specific needs.

Title:
Archeometric dating: thermoluminescence, radiocarbon and archaeomagnetism

Description:
Within archeometry, the application of dating methods is essential to establish the chronology of archaeological sites. Cultural materials in an archaeological context are varied and some of them can be very good indicators of temporality, however, is very important the analysis of previous archaeological context to the sampling and know the characteristics of cultural materials in the site (pottery, bones, stucco, shells, organic rest, floors, ovens, etc.) to apply the appropriate method of dating for each material. Sometimes the application of dating methods cannot be carried out for reasons such as improper handling of samples (contamination), the samples are subjected to artificial or ambient conditions affecting measurement or lack of field elements that must be measured in situ.

It is essential archaeological context analysis and obtaining appropriate materials for these indicators are correct timing for the event you want to date , this defines the establishment of reliable chronologies and more accurately. This course aims to provide the necessary elements to develop a strategy appropriate sampling for each archaeological context, besides the criteria that must be followed to select the appropriate method of dating, in addition to the basics and sampling techniques required to implement each the methods studied in the course. Knowledge of the scope and limitations of each method help us integrate precisely in order to generate more robust and consistent chronologies.

Title:
Different applications of the MT method and new generations of UMT systems in data acquisition, processing and management

Description:
The magnetotelluric method (MT) is a passive method of geophysical exploration, where the equipment with the same sensors’ arrangement measures electric and magnetic fields that naturally flow underground at different depths. That is, after its installation the equipment is left measuring without changing its position, with a respect of the time length of measures and sampling frequency, the subsoil information can be obtained from the near-surface to hundreds of km deep.

Therefore, the MT method is widely used for various exploration studies, ranging from shallow depths with environmental problems, to deeper investigations for mineral exploration, groundwater detection, prospecting for geothermal and petroleum energy sources, etc. In an addition to being an invaluable tool in the aforementioned studies, it can be used for greater depth investigation for regional tectonic and continental geodynamic processes.

Since the late 1980s, the development of the use of remote reference technique, robust processing, corrections of different types of distortion, multidimensional modeling and new inversion methods have made the Interpretation of magnetotelluric data to be one of the most effective methods for this type of research. In this course will use a new generation Ultra wide-band MT system, developed by the company Phoenix Geophysics, which provides simultaneous recording of Audio Magnetotelluric (AMT), Magnetotelluric (MT) and Long Period (LP) bands of the natural electromagnetic field in one recording. Where the MT data acquisition has been simplified, reducing system setup time and providing additional data quality control and assessment capabilities in the field, and data processing.

The course will consist of an introduction to the MT method, where the basic theory of the method will be presented. Subsequently, the measurement equipment will be described, it will be shown how the acquisition of data in the field is generated, and real data processing will be performed to obtain the apparent resistivity curves. Finally, several examples of studies in Mexico and the world will be presented in different exploration areas, such as: groundwater, mineral and oil exploration, geothermal studies, volcanology, and plate tectonics.
