Stakeholders of the Morro Bay National Estuary Program in California worked with resources from the EPA's Climate Ready Estuaries program to identify their climate risks. Their results helped them prioritize actions for building resilience.

The goal of this unit is for students to gain an awareness of several potential ways to mitigate climate change. Many climate solutions exist, are in use, and can be expanded in scale. Students will examine solutions from Bending the Curve, explore carbon sequestration by trees, coastal wetland restoration, and food waste reduction in more detail. They will propose three (3) realistic solutions that could happen at an individual, school, or community scale that would assist in mitigating climate change.

In this video segment from NatureScene, explore Cartwheel Bay, a wetland in South Carolina, and learn about the variety of carnivorous plants native to this unique landform.

Increasingly volatile climate and weather; vulnerable drinking water supplies; shrinking wildlife habitats; widespread deforestation due to energy and food production. These are examples of environmental challenges that are of critical importance in our world, both in far away places and close to home, and are particularly well suited to inquiry using geographic information systems. In GEOG 487 you will explore topics like these and learn about data and spatial analysis techniques commonly employed in environmental applications. After taking this course you will be equipped with relevant analytical approaches and tools that you can readily apply to your own environmental contexts.

This module introduces students to the fundamental principles and uses of electrical resistivity, with a focus on an environmental application. Students explore the characteristics and environmental setting of Harrier Meadow, a saltmarsh just outside of New York City. They investigate the relationship between electrical resistivity and physical properties of the soil in the marsh. Students also discover how variations in survey configuration parameters control investigation depth (how far into the ground the signals sense) and spatial resolution (what size objects can be detected). Finally, students learn about and then perform geophysical inversion, which is the process of estimating the geophysical properties of the subsurface from geophysical observations. In the final unit of the module, students evaluate the extent to which the geophysical dataset and direct physical measurements support the hypothesis, introduced in Unit 1, accounting for the distribution of Pickleweed in Harrier Meadow.
This module is intended to require approximately 2-3 weeks of class time. Teaching material includes PowerPoints that may be used in lectures or provided for self-guided learning, exercises, and handouts that ask students to synthesize what they learn from the exercises. In addition, multiple choice and short answer questions can be given to students as homework, on quizzes, or on exams.

Geography 431 is designed to further understanding of the natural processes of aquatic ecosystems, management of water resources, and threats to sustaining water quantity. Develop awareness and appreciation of the perspectives about water as a precious resource, commodity, and sometimes hazard. Learn how and why water is distributed unevenly around the Earth. Examine how resource management decisions are strongly related to water availability, quantity, and quality. The course examines water resources management; dams and dam removal; provision of safe potable water; threats to water quantity and quality; land use changes; the water economy; water laws and policy; institutions for water management at the global, national, regional, and local scale; and issues of water security and climate change.

Geysers and grizzlies and glaciers, oh my. The national parks may be America's best idea, saving the finest parts of the nation for everyone to enjoy forever. What better way to learn about the natural world than to tour the parks with us? We'll explore how the mountains and valleys formed and why they often come with volcanoes and earthquakes. You'll see what really killed the dinosaurs and how we can help save their modern relatives in the parks. With film clips, slide shows, and our geological interpretations of classic rock songs, isn't it time for a road trip?

This activity is field investigation where students map a neighborhood wetland and generate various watershed questions. Students identify engineered structures in or around this wetland and consider how flood water can be controlled.

In this investigation, students gather biotic and abiotic data and samples in the field, develop an experiment to test another abiotic factor in the lab, synthesize group data, interpret their findings and make a claim on the health of the wetland ecosystem.

Activities offer students the opportunity to learn about multiple facets of waterbodies and pollution, including aquatic life (indicator species), local concerns, and public outreach through research, teamwork, and role-playing exercises.

In this video from WOSU Columbus, learn about the types of communities of plants, animals, birds and fish that abound in wetlands.

The goal of the second grade Wetland: Habitat storyline is to introduce students to wetlands and the living things that call them home. In this storyline students develop an understanding of what a habitat is, different types of habitats, what living animals and plants can be found in a wetland, and what plants need to grow

The goal of the fifth grade Wetland: Ecosystem Benefits storyline is to build on students’ previous knowledge of plant/animal needs, habitats, and protection of Earth’s resources. In this storyline students develop an understanding of wetland ecosystems, photosynthesis, what plants need to grow/gain mass and blue carbon wetlands.

Coastal wetlands bring many benefits to ecosystems including their ability to sequester carbon and mitigate fluctuations in sea levels. Students will understand the ecosystem benefits of coastal wetlands with a focus on the potential of estuaries for climate related planning.

As sea level rises, wetlands and marshes must move inland, or drown. The Sonoma Land Trust is using innovative strategies to restore and enhance marshlands and the ecosystems they support.

This course is a client-based land analysis and site planning project. The primary focus of the course changes from year to year. This year the focus is on Japan’s New Towns.
Students will review land inventory, analysis, and planning of sites and the infrastructure systems that serve them. They will also examine spatial organization of uses, parcelization, design of roadways, grading, utility systems, stormwater runoff, parking, traffic and off-site impacts, as well as landscaping. Lectures will cover analytical techniques and examples of good site-planning practice. Requirements include a series of assignments and a client-based project.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Mangrove forests are home to many varieties of methanogens, microbes that digest surrounding carbon into methane under low-oxygen conditions. Despite their important role in the global carbon cycle and climate change, the metabolic potentials of two novel methanogens in mangroves remain poorly understood. A new study reports on the ecological importance of Methanofastidiosa (MF) and Methanomassiliicoccales (MMA), two recently discovered groups of methanogens found to dwell naturally in the Mangrove Nature Reserve in Shenzhen, China. Using metagenomics, researchers examined how MF and MMA produce methane. Results showed that the two groups of microbes both use hydrogen to produce methane from compounds found naturally in mangrove sediments, including methylsulfides, methanol, and methylamines. This marks the first time the two groups of methanogens have been studied in the wild and could help scientists understand how these microbes contribute to global methane emissions and a changing climate..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Students will conduct a virtual exploration of Harrier Meadow, a saltmarsh in the New Jersey Meadowlands. They will identify its vulnerability to pollution, its tidal connection to the Hackensack Estuary and the Atlantic Ocean along with its proximity to New York City. Vegetation patterns within this wetland will be explored, focusing on a salinity tolerant native plant (Pickleweed) that is returning to the marsh. The return of such native species is critically important to wetland restoration efforts that aim to reclaim native habitat following decades of environmental degradation since the industrial revolution. These vegetation patterns are the focus of resistivity and electromagnetic surveys that the students explore in the subsequent units of this module. The geophysical surveys aim to better understand the underlying factors controlling the distribution of Pickleweed. By understanding where the Pickleweed is thriving, restoration efforts could subsequently be improved by locating regions of such wetlands with similar underlying factors where Pickleweed (and other native plants) could be successfully reintroduced. In the first unit of this module, students will use Google Earth (on the web), high-resolution video acquired from an Unmanned Aerial Vehicle (UAV) and an ArcGIS Storymap in their exploration. Primary outcome: students comprehend the association between salinity and Pickleweed and formulate plans to test a hypothesis for Pickleweed persistence/patterning in Harrier Meadow that will ultimately be implemented using near surface geophysical methods in the remaining units of the module.

Archie (1950) defined the term petrophysics to describe the study of the physics of rocks, particularly with respect to the fluids they contain. Although originally focused on geophysical exploration, petrophysics concepts are now used to interpret near surface geophysics measurements made to address environmental and engineering problems. This unit investigates relationships between these geophysical measurements and the physical and chemical properties of soils and sediments in the Earth's near subsurface. The specific focus is on the electrical properties of soils and how they are related to the ionic concentration of the pore fluids, the water content, porosity and grain size. Field results from a geophysical survey performed in Kearny Marsh, close to Harrier Meadow, are included to illustrate how electrical conductivity of a soil measured with an electromagnetic sensor is a good proxy for pore fluid ionic concentration, in this case related to contamination from a bordering landfill.

Near surface geophysical measurements are performed by moving sensors across the Earth's surface. Active geophysical sensors transmit a signal into the Earth and record a returned signal that contains information on the physical and chemical properties of the Earth (see Unit 2). This unit introduces the student to the basics of geophysical data acquisition using two techniques that record variations in the electrical conductivity (see Unit 2) of the Earth: [1] electrical imaging (EI), and [2] electromagnetic (EM) conductivity mapping.











Basic concept of electrical imaging measurements

Provenance: Lee Slater, Rutgers University-Newark
Reuse: This item is in the public domain and maybe reused freely without restriction.
Electrical imaging is a galvanic geophysical approach whereby electrical contact with the Earth is made directly via electrodes (typically metal stakes) that are inserted into the ground. Electromagnetic conductivity mapping is a non-contact approach whereby the physics of EM induction is used to sense changes in electrical conductivity. The advantages and disadvantages of using galvanic (EI) and non-contact (EM) techniques for measuring electrical conductivity are described. Ohm's Law is introduced and students investigate how electrical resistance measurements are related to the electrical conductivity of soils. Field implementation of both EI and EM techniques is demonstrated using surveys performed in Harrier Meadow as an example. Students investigate how variations in survey configuration parameters (e.g. electrode configuration and electrode spacing in EI, frequency and coil spacing in EM) control investigation depth (how far into the ground the signals sense) and spatial resolution (what size objects can be detected). The concept of pre-modeling a geophysical survey (i.e. running some simulations of likely effectiveness of the methods before going to the field) to evaluate expected investigation depth and sensitivity is introduced. The Excel-based Scenario Evaluator for Electrical Resistivity (SEER) tool provided by the United States Geological Survey (USGS) is used to demonstrate some key concepts.
