Lesson Plan (Grades 6-12): Bay Drift – Tracking Ocean Pollution

This lesson plan teaches middle and high school students how ocean currents transport debris, spilled oil, and other pollutants through the ocean environment.

The lesson uses real data collected during the Biscayne Bay Drift Card Study (Bay Drift), a citizen science study that used Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) GPS drifters and small wooden drift cards to observe local currents and pollutant transport.

Bay Drift: Tracking Ocean Pollution” can be completed in a single class period and provides teachers with background information on ocean pollution transport as well as step-by-step instructions for introducing students to the study. Students will learn how to: (1) analyze drifter data; (2) describe, compare, and contrast both types of drifters used in the study; and (3) use local currents to predict where drifters and pollutants will go. A Story Map of the Bay Drift study was developed to compliment the lesson: https://arcg.is/1e0T40.

A free downloadable copy of “Bay Drift: Tracking Ocean Pollution” is available here.

Young Scientist Visualizes Risk to Whales in an Oil Spill Scenario

Fueled by a passion for science and endangered species, Alek designed and executed a research project that involved scientists from eight institutions, four-hundred drift cards, and over a year’s work. A substantial undertaking for any scientist, this is even more impressive because Alek is seven years old.

Alek Finds a Calling

Alek lives in Washington near the coast where he has spent much time watching and learning about orca whales, specifically the Southern Resident Killer Whale of which there are about eighty known remaining.

“I really like the white eye patches they have,” he said. Scientists at the Center for Whale Research near Alek’s home are working hard to track and protect these orcas. “Dr. Ken Balcomb is the main whale researcher there,” said Alek. “He inspires me because he stands up for these whales’ freedom and protection.”

When Alek was five, he read a book that discussed the environmental impacts of the Deepwater Horizon and Exxon Valdez oil spills, which drove his desire to help protect the ocean ecosystem near his home. “My heart broke because it was so sad,” he recalled. “The whole ocean ecosystem was contaminated for hundreds of miles, and lots of ocean animals died.” Every year, thousands of oil tankers cross the Salish Sea, an intricate network of coastal waterways near the United States-Canadian border where many of these whales live. Alek became concerned that the Southern Resident Killer Whales could encounter and be affected by large amounts of oil if a spill occurred.

A Little Help From His Friends

Alek began gathering books on oil spills and visiting university research websites when he was six, focusing on oceanography departments that study spills.

He emailed scientists around the country, including Piers Chapman and Tamay Özgökmen – the directors of the GISR and CARTHE consortia, respectively – for input on how to proceed. More than ten prominent researchers agreed to sit on Alek’s science committee and advise his research.

Alek chose to conduct a drift card study after finding out it would take more than a year to obtain a permit to deploy GPS-enabled drifters, an ocean current tracking method that he wanted to pursue like Özgökmen has done. Drift cards, made of wood or other lightweight materials that float on the water’s surface, are another tool that can show how currents move through an area. Chapman has used drift cards, deploying them at a fixed location and plotting times and points on a map where people report cards they discover (the cards have printed explanations about their purpose and reporting instructions). As Alek’s project developed, Chapman and Özgökmen answered his questions and reviewed his reports.

“Alek is an incredibly motivated young man,” said Chapman. “I was very happy to suggest possible ways that he could analyze his data while putting his report together and make suggestions to help give the video he made about his research more impact. He’s a great kid and deserves every encouragement.”

Alek’s family was supportive and helped him with the things he couldn’t do himself, such as traveling to various sites and using an electric saw to cut wood into drift cards. However, they encouraged Alek to raise the money needed for the project himself so that he would get a broader experience of being a scientist.

Alek sent letters asking people to sponsor a drift card for one dollar per card. He collected $460 from donors across the country, including many scientists, and even received a letter from President Obama thanking him for his work. He used this money to purchase biodegradable and nontoxic materials to build the cards.

If You Build Them, They Will Drift

Alek made two batches of 200 cards, each batch labeled either “A” or “B.” He deployed the cards at Rosario Strait, a dangerous channel that many ships pass through on their way south. He released the first set on September 6, 2014, as the tide was going out and the second set as the tide was coming in on September 21. Days and weeks went by, and one-by-one people in the area returned 181 drift cards. He even received information about one that had floated all the way to Alaska! He calculated the GPS coordinates where each card was found, logged them into a spreadsheet, and used this information to populate maps on Google Earth.

Some people who found drift cards sent Alek a photo

Alek then mapped the probable path oil would take through the Salish Sea should a spill occur in the Rosario Strait. He compared these paths to reports of orca migrations to show where their paths might encounter oil. “The orcas don’t know how to avoid oil in water, so they would swim right through it,” said Alek. “It is sad to find out that, if my oil spill simulations were real, every single one of the endangered orcas here would be at risk of oil contamination.”

When he completed his study, Alek created a website about the project. The site contains an overview of his work with maps, charts, and graphs showing his findings and suggestions for what the public and lawmakers can do to reduce our dependence on oil and protect endangered species. No one from congress has responded yet, but many others have, including Jane Goodall who sent an email praising his efforts to call attention to these whales’ potential risk. Alek also created a short video summarizing his study, a one hour video detailing his project, and a 154-page scientific report.

“I was so impressed by Alek’s one-hour movie of his year-long study—the level of detail was amazing,” reflected Özgökmen. “We are looking at a hardworking, brilliant young mind here. I can only hope that he gets the best education this country can offer, as he will have much to contribute to our society in the future.”

Alek’s Perseverance

Alek admitted that creating the spreadsheets and maps was more work than he expected. After several months of data entry and analysis, there were times when he felt like giving up because of the work volume.

However, he said that instead of quitting, he looked to the great scientists of history to remind himself to keep going, “I thought: What if they gave up? If Copernicus gave up, we might never know the sun was the center of the solar system. If Charles Darwin gave up, we might not know about evolution. If Crick and Watson gave up, we might not know how genetics and DNA work. I learned I couldn’t give up, because everything that is important in life takes hard work!”

What’s next on Alek’s radar? He sees “endless possibilities” for more science in his future. “Some of the things I am thinking about are chemistry, building an underwater ROV, and 3D printing,” he said. He also stated that, although still many years in the future, he hopes to study marine science in college. One thing is certain: whatever direction he eventually pursues, Alek has already proved himself a precocious scientific thinker in the world of oil spill research.

Boaters, Vacationers, and Beach Lovers Report Drift Cards for Oil-Spill Research

Summer fun check list: 1. enjoy the sun, sand, and surf along the beautiful Gulf of Mexico; 2. track ocean currents; and 3. win a prize.

Track ocean currents? Win a prize? Yes! Adults and children from Florida to Texas are calling, emailing, and going online to report little yellow cards they find in the water and on the beach. The locations of these cards give scientists important information for an ongoing study to aid future oil spill response. The data are important enough to be prize-worthy and the public’s participation in science is getting regional media attention.

It happened just like that for Patricia and her husband from Ohio, vacationing in Panama City Beach, FL, one of their favorite summertime spots. They spotted a bright yellow card floating on the water. After looking at it, they realized it was not trash but rather part of a scientific study to track Gulf currents. They followed the instructions on the card to report its location and they won the first $25 gift card.

Scientists took great care in manufacturer specifications to make the drift cards environmentally friendly, not adding to ocean trash or toxins. Manufacturers used biodegradable mahogany wood, making the break down process similar to what happens naturally when tree limbs fall into water. They used non-toxic paint that does not contain Tributyltin (TBT) and sealed the print using a UV process, not solvents.   The cards have an estimated water-floating life of about three to six months, depending on sea conditions and interactions with sand and rocks. Instructions on the drift cards are in English and Spanish.

The Gulf Integrated Spill Research (GISR) consortium is using the cards as part of a larger research effort to understand how wind and currents move items on surface waters. Using field and laboratory experiments, scientists with GISR are working to improve prediction models in the event of another oil spill. Dr. Piers Chapman at the Texas A&M University (TAMU) leads the GISR consortium that consists of ten research institutions across six U.S. states and Britain. Volunteer researchers will release 5,000 drift cards from vessels located across the Gulf. Click here for an interactive map that shows up-to-date drifter card deployment and landing sites.

The deployment and recovery data from the drift cards will go into a particle tracking model – the Larval TRANSport Lagrangian model (LTRANS). Lagrangian models help scientists understand the many factors which influence the hidden pathways along which air and water flow. Elizabeth North at the University of Maryland runs the LTRANS code working to develop more realistic particle tracking capabilities. Other GISR project scientists are working to develop a nested wellhead-to-beach Gulf circulation model against which the drift card data will be compared. In addition, Drs. Rob Hetland and Kristen Thyng (TAMU) have developed a web-based particle tracking tool that will aid such comparisons.

Dr. Joseph Kuehl at TAMU explains that GISR will compare the data from the cards to computational models of Gulf currents, “It will be interesting to compare the drift card observations to numerical particle trajectories, since the drift cards will be influenced by the wind and waves like a surface slick.  It is impractical to expect accurate 1-1 comparisons between the model trajectories and drift cards.  Instead, we will look for differences in larger scale ocean features between numerical trajectories, drift cards, and satellite data. The shelf break tends to be a barrier to transport, acting to isolate the coastal zone from the open ocean.  Perhaps, we will find that drift cards do not see the same transport barriers that we are used to thinking about.”

The first 1,250 drift cards released elicited more than 200 responses. In previous drift card studies he was involved with, Chapman reported a two percent response rate. If reporting continues at current levels, the response may climb to twenty percent. This increased rate is likely due to a combination of the encapsulating nature of the Gulf’s coastline (as compared to previous open ocean drift card releases) and high public and media interest in the Gulf oil spill. The first card was found by Rebecca in Pensacola Beach, FL. That same day another was recovered by David in Alabama. These reports came only four days after the first set of cards had been deployed!

“Drift cards are deployed in groups of ten, so it is interesting to look at how they spread.  Cards deployed within a few feet of each other can end up miles apart,” says Kuehl.

The Gulf of Mexico attracts many visitors in the summer, increasing opportunities for people from different places to find and report drift cards.  For example, Matt and his fiancé came to coastal Alabama to get married and found three cards in two days. Veli and her son from Finland were vacationing in Corpus Christi, TX, and found a card on a crowded beach. Alvaro, an educator, was leading a group of youngsters near the Texas Padre Island National Seashore when they found a card. Kelly, also a teacher, found her card at Crystal Beach and said she cannot wait to share the story with her students when school resumes. Kim and Mike found six cards while fishing off the Louisiana coast – the most cards found in a single day.

And the prizes? Each month, the research team sends a $25 gift card to a person randomly-selected by a computer from names of people who report a card. Everyone who submits drift card information is eligible for the drawing. While the money is a nice incentive, helping scientists better understand Gulf currents makes this a win for everyone who lives, works, and plays along the Gulf of Mexico. The drift card program will continue until reports stops.

The GISR consortium wishes to thank the many universities and research organizations who have voluntarily distributed the drift cards at sea and help make this program a success.
