This 2018 edition is the first to be released in a digital, fully-interactive format, designed to highlight facets of the Pacific Northwest landscape with novel approaches to data presentation. Where previous editions of the atlas were designed to ask and answer questions, this atlas serves as a platform for the geographically curious to explore the region, providing as many critical questions as it does critical answers.

Beyond this page are maps of the familiar and the unfamiliar. Migration maps highlight human movement between the Pacific Northwest and the rest of the United States; a wildfire timeline chronicles the year-to-year spread of modern and historical fires; and the watershed guide abandons traditional political boundaries in favor of natural, hydrological borders. All data in the atlas were gathered from publically accessible sources, compiled using open-source software and coding libraries. This is an atlas designed to be open, responsive, and to satisfy the geographic curiosity of any and all interested.

"This undergraduate class is designed to introduce students to the physics that govern the circulation of the ocean and atmosphere. The focus of the course is on the processes that control the climate of the planet.AcknowledgmentsProf. Ferrari wishes to acknowledge that this course was originally designed and taught by Prof. John Marshall."

These graphs show carbon dioxide measurements at the Mauna Loa Observatory, Hawaii. The graphs display recent measurements as well as historical long term measurements. The related website summarizes in graphs the recent monthly CO2, the full CO2 Record, the annual Mean CO2 Growth Rate, and gives links to detailed CO2 data for this location, which is one of the most important CO2 tracking sites in the world.

This is a multi-step activity that helps students measure, investigate, and understand the increase in atmospheric CO2 and the utility of carbon offsets. It also enables students to understand that carbon offsets, through reforestation, are not sufficient to balance increases in atmospheric C02 concentration.

This image depicts a representative subset of the atmospheric processes related to aerosol lifecycles, cloud lifecycles, and aerosol-cloud-precipitation interactions that must be understood to improve future climate predictions.

Survey of atmospheric and oceanic phenomena including the discussion of observations and theoretical interpretations. Topics covered include: monsoons; El Nino; planetary waves; atmospheric synoptic eddies and fronts; gulf stream rings; hurricanes; surface and internal gravity waves; and tides. In this course, we will look at many important aspects of the circulation of the atmosphere and ocean, from length scales of meters to thousands of km and time scales ranging from seconds to years. We will assume familiarity with concepts covered in course 12.003 (Physics of the Fluid Earth). In the early stages of the present course, we will make somewhat greater use of math than did 12.003, but the math we will use is no more than that encountered in elementary electromagnetic field theory, for example. The focus of the course is on the physics of the phenomena which we will discuss.

This is a figure from the 2007 IPCC Assessment Report 4 on atmospheric concentrations of carbon dioxide, methane and nitrous oxide over the last 10,000 years (large panels) and since 1750 (inset panels).

Create multiple versions of helium atoms and make observations of how changing protons, electrons, and neutrons affect atoms.

Create multiple versions of various atoms and record the number of protons, electrons, and neutrons in a table.

Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.

In this activity, students will explore how the Law of Conservation of Energy (the First Law of Thermodynamics) applies to atoms, as well as the implications of heating or cooling a system. This activity focuses on potential energy and kinetic energy as well as energy conservation. The goal is to apply what is learned to both our human scale world and the world of atoms and molecules.

Both of these lessons are classroom activities that require students to build models that display understanding of atoms and molecules. One lesson is structured while the other is guided.

In this lesson, the students will discover the relationship between an object's mass and the amount of space it takes up (its volume). The students will also learn about the concepts of displacement and density.

This is a photo essay linked to a New York Times story about climate-related stressors on forests -- including mountain pine beetles, forest fires, forest clearance, and ice storms -- and the importance of protecting forests as an important carbon sink.

This video shows where and how ice cores are extracted from the West Antarctic Ice Sheet. The cores are cut, packaged, flown to the ice core storage facility in Denver, further sliced into samples, and shipped to labs all over the world where scientists use them to study indicators of climate change from the past.

We use motion detectors and a bowling ball to find relationships velocity, mass, and energy.

Attractive forces between particles play a role in the properties of the three states of matter. The strength of the attractive force between particles is one factor that determines if a particular substance will be a solid, liquid, or gas. Vary the strength of the attractive force between particles in this model. Note that for a real substance, the strength does not vary, but this model shows how the strength of the attractive force determines the state of matter if the temperature is fixed.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

This is a lesson which gives students the opportunity to imagine they are scientists, provides them with a basic understanding of aurora and helps them to use creative methods in their observations. First, students will study the scientific aspect of the aurora. They will also look at images of the aurora (both pictures and illustrations) and describe what they think of when they see them. These descriptions can be stored in the student portfolios as they will be useful in future lessons. Includes teacher notes and instructions, student workshops and an online, animated story, and related teacher resources on aurora. This is lesson three of a collection of five activities that can be used individually or as a sequence; concludes with a KWL (Know/Want-to-know/Learned) assessment activity.
