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.

He swims with penguins, dives under an iceberg, meets a massive jellyfish 3 feet across, and has an incredible encounter with a Leopard seal, the apex predator of Antarctica. Part 2 finds Jonathan continuing his exploration of Antarctica including an encounter with a Leopard seal. This program won a New England Emmy Award!

In this video Jonathan visits the New England Aquarium as a volunteer aquarist for a day to learn what it takes to care for thousands of fish in dozens of exhibits, up to the massive 200,000 gallon Giant Ocean Tank (GOT). What he finds is an eye openerŰÓitŰŞs not all fun and games. Maintaining an aquarium is serious work. But it does have its benefits, as Jonathan discovers while diving in the GOT and feeding the sharks. This segment won a New England Emmy Award!

Located near Townsville, North Queensland, AIMS researchers collect and analyze data to improve our understanding of the marine world, and to find science-based management practices that ensure long-term sustainable use and development of marine resources. Site features information on facilities, faculty, current projects, open house and other events, and employment opportunities. Also features the Mariner's Journal, a log from several AIMS research cruises.

In the open ocean around the Bahamas, pods of wild Spotted Dolphins frolic in the sunshine. Sometimes, they get bored and approach boats. In this educational video, Jonathan joins dolphin expert Wayne Scott Smith to learn how dolphins interact with each other. Jonathan learns how to play the Bandana Game, a game of -keep away- that the dolphins invented and like to play with Scott. Please see the accompanying study guide for educational objectives and discussion points.

Students study a population of beluga whales to learn about the environmental issues that the whales currently face. They then work in teams to develop suggestions for how to help protect the population of belugas, which they present in a public service announcement (PSA).

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! Please see the accompanying study guide for educational objectives and discussion points.

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. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

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.
