During World War Two, a fierce battle between American and Japanese forces on Kwajalein atoll left a trail of debris on the deep lagoon floor. This lagoon now has one of the largest collections of well-preserved aircraft in the world. In this video, as part of the first ever film crew allowed onto this secret military base, Jonathan explores a B-25, F4-U Corsair and Dauntless dive bomber still sitting on the bottom of the ocean, as if ready to take off. Please see the accompanying study guide for educational objectives and discussion points.

This book began as lecture notes for an Oregon State University course in fluid mechanics, designed for beginning graduate students in physical oceanography. Because of its fundamental nature, this course is often taken by students outside physical oceanography, e.g., atmospheric science, civil engineering, physics and mathematics. In later courses, the student will discover esoteric fluid phenomena such as internal waves that propagate through the sky, water phase changes that govern clouds, and planetary rotation effects that control large-scale winds and ocean currents. In contrast, this course concerns phenomena that we have all been familiar with since childhood: flows you see in sinks and bathtubs, in rivers, and at the beach. In this context, we develop the mathematical techniques and scientific reasoning skills needed for higher-level courses and professional research. Prerequisites are few: basic linear algebra, differential and integral calculus and Newton’s laws of motion. As we go along we discover the need for the more advanced tools of tensor analysis.

In this video, Jonathan treks all the way to Antarctica to investigate life south of the polar circle. Along the way he dives in the majestic kelp forests of Patagonia, where crabs rule the sea floor. Once he arrives in Antarctica, his adventures continue. He swims with penguins, dives under an iceberg, meets a massive jellyfish 3 feet wide, and has an incredible encounter with a Leopard seal, the apex predator of Antarctica. Part 1 finds Jonathan diving in Ushuaia, Patagonia in Argentina before boarding the ship to Antarctica, then he finally gets to Antarctica and meets some penguins! This program won a New England Emmy Award! Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

This graduate course will introduce students to the processes controlling phytoplankton, zooplankton, heterotrophic bacterial and benthic infaunal growth and abundance. We'll do a broad-scale survey of patterns of productivity and abundance in the coastal zones, upwelling centers, gyres, and the deep sea. We'll briefly survey ecosystem simulation models, especially those applicable to the Gulf of Maine. Readings will be from the primary literature and a few book chapters. The effects of anthropogenic effects on marine communities will be stressed throughout. Calculus will be used throughout the course, but there is no formal calculus requirement.

In this video, Jonathan joins Charlie Donilon on his shark charter boat in Rhode Island, Massachusetts, and learns about how shark tagging has shed light on the biology of and behavior of Blue sharks. Tagging has shown that these incredible swimmers actually migrate completely across the Atlantic ocean. Jonathan tries his hand at tagging a shark and then swims with Blue sharks. We also learn that Blue sharks are not nearly as vicious as they have been reputed to be, and the divers are actually able to pet the sharks!

This chapter provides teachers with instructions to install a school weather station, and to build simple instruments to monitor weather conditions. Materials need to create a homemade weathervane include a two-liter soft drink bottle, a shallow metal pie pan, a plastic drinking straw, and a compass. Building an anemometer requires plastic cups, soda straws, a pencil with an unused new eraser on the end, a paper punch, and a thumbtack. Thermometers and a rain gauge must be purchased. A data table is included for estimating windspeed using the anemometer. The chapter includes research ideas that allow students to validate their instruments and test the predictive capability of resources such as the Farmer's Almanac. This resource is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9.

This activity has students create a Cartesian diver, which will act in some ways like a submarine. Students will adjust the amount of air and water in an inverted test tube (the "diver") so that it at first barely floats in a water-filled bottle. Then, they will squeeze the closed bottle to create higher water pressure, causing the diver to sink. Releasing the bottle allows the diver to float again. Written instructions, a list of materials, and illustrations are included.

In this scenario-based, problem-based learning (PBL) activity, students investigate cloud formation, cloud classification, and the role of clouds in heating and cooling the Earth; how to interpret TRMM (Tropical Rainfall Measuring Mission) images and data; and the role clouds play in the Earth’s radiant budget and climate. Students assume the role of weather interns in a state climatology office and assist a frustrated student in a homework assignment. Learning is supported by a cloud in a bottle and an ice-albedo demonstration, a three-day cloud monitoring outdoor activity, and student journal assignments. The hands-on activities require two 2-liter soda bottles, an infrared heat lamp, and two thermometers. The resource includes a teacher's guide, questions and answer key, assessment rubric, glossary, and an appendix with information supporting PBL in the classroom.

Has your attention recently been caught by news of coastal catastrophes such as hurricanes and tsunamis? Do you wonder why so many coastal communities in the world are vulnerable to flooding and other coastal hazards? Have you considered what coastal flood protections cities like Houston and Miami will need in the future to protect their residents? This course will provide a better understanding of these phenomena. We present a global perspective of coastal landscapes, the geologic processes responsible for their formation, and ways that society responds to hazards like sea level rise and catastrophic weather events. You will participate in active learning exercises such as analyzing real-world datasets and applying critical thinking to real-world societal problems while investigating a coastal community.

Think science has all the answers? Think again. This course will use real, authentic data to explore and investigate modern controversies in Earth Sciences. Use tide gauge records to understand how countries around the world attempt to protect themselves from tsunami events. Process seismic data to predict earthquake recurrence in the New Madrid seismic zone, right here in the breadbasket of the US. Sort through the millions of years of the geologic timeline to shed some light on what actually did, and did not, kill the dinosaurs. Finally, use global atmospheric data to understand how misrepresentation of data can be used to paint a distorted view of past, present, and future climate.
