Marine Debris and its Effects on the NWHI

Summary Students will learn that many animals that live in the ocean come into contact with discarded plastic. Because this plastic is not natural to their environment, the animals don’t recognize it or know what do about it. They encounter plastics most often as a result of their feeding behaviors. Often they get entangled in it, are cut and injured, or think it is food and try to eat it.

Objectives • Students will gain an understanding of how currents serve as

a vector for Marine Debris. • Students will learn how different feeding techniques of Sea

Birds of the NWHI determine what types of Marine Debris (Plastics) they may ingest.

• Students will be able to understand that different types of plastics float, sink, or stay in the water column and are neutrally buoyant.

Background The potential for ingestion of plastic particles by open ocean filter feeders was assessed by the Algalita Marine Research Foundation by measuring the relative abundance (number of pieces) and mass of floating plastics and zooplankton near the central high­pressure area of the North Pacific central gyre (the gyre is a large recirculating area of water half­way between California and Hawaii). Plankton abundance was approximately five times higher than that of plastic, but mass of plastic was approximately six times greater than that of plankton. This area is far from land, and many types of marine life feed here.

The effects of plastics on marine life can be devastating. Aquatic animals may be harmed by plastic objects in a variety of ways, depending on the shape and buoyancy of the object. These animals may suffer injury of even death from their encounters with plastics. Animals can be harmed through entanglement, laceration, suffocation, and ingestion.

The buoyant properties of water allow some plastics to float, some to sink, and some to stay in the water column. The types of plastics marine animals may come into contact with depend on where they live and eat: at the water’s surface, its bottom, or floating in the water column between the surface and bottom. All we see are the plastics on the surface, but there are many different varieties and shapes of plastic objects below the surface. Because we can’t see this pollution, we may forget that it exists. As cities grow and more plastics are produced and enter the marine environment, marine species will continue to be affected unless we make careful choices regarding plastics use and disposal.

Procedure Activity 1: You Are What You Eat: Plastics and Marine Life

1. Use ideas from the Voyage to Kure Viewing Guide to set the scene. Pay particular attention to the Segment Suggestions for the marine debris theme (film clips from Laysan Island and Midway Atoll). If you do not have access to the Voyage to Kure episode, try to find pictures of marine debris to show the students and lead a discussion about the danger to animals and ecosystems. What do students think about plastics in the ocean? Where does plastic go? Does it go away? What types of animals are most affected?

2. Continue class discussion by exploring the many ways we use plastics in our daily life.

3. Pass out Plastics and Their Uses student handout and discuss the different types of plastics. Note that some cities only accept Society of the Plastics Industry (SPI) codes 1 and 2 for recycling. Although many of the other types of plastic are labeled as “recyclable,” in reality, this does not occur and the majority of plastics end up in landfills.

4. From water bottles to computers, we rely on the convenience and availability of plastics to provide many of today’s necessities. List on the board the shapes that plastic can come in, and have students give examples of what they are used for:

One­dimensional objects (line, rope, strapping brands) Two­dimensional objects (sheets, bags) Reticulated (netting, six­pack rings)

Page 3: Marine Debris and its Effects on the NWHI · 2017-08-17 · • Students will learn how different feeding techniques of Sea Birds of the NWHI determine what types of Marine Debris

Hollow­bodied (bottles, fishing floats) Small particles (Styrofoam, pellets used in making plastic objects) Angular (boxes, crates)

5. Discuss the marine zones in which animals feed (surface, pelagic, and benthic). Have students brainstorm what types of animals might live and feed in each of these zones.

6. Either divide the class into small groups (3­4 students) or distribute materials to individuals. Distribute copies of the You Are What You Eat handout, a set of the Marine Animal Cards, and a Marine Animal Feeding Habits and Plastics Risk Chart to groups or individual.

7. Have students read You Are What You Eat handout and complete the worksheet activity, placing the marine animal cards on their charts. Keep in mind that there are many different possible “correct” answers; students’ need to primarily have a rationale for their choices.

8. After the groups or individuals have completed the activity, draw the chart on the board. Have each group or student choose one form of plastic (one­dimensional, two­ dimensional, small particles, etc.) and present to the class their results and rationale of what species would most be affected. Allow time to propose different answers, discuss them, and wrestle with different conclusions.

9. Conduct a class discussion on how to reduce the amount of plastics in the marine environment.

You Are What You Eat: Plastics and Marine LifeJust because you can’t see it doesn’t mean it isn’t there. Whether it sinks or floats, plastics in the sea spell

trouble for all the animals in the ocean. By matching animal cards to plastic risks, students find out the many

ways marine life can be affected by plastics in their aquatic home.

Many animals that live in the ocean come into contact with discarded plastic. Because this plastic is not natural to their environment, the animals don’t recognize it or know what to do about it. They encounter plastics most often as a result of their feeding behaviors. Often they get entangled in it, are cut and injured, or think it is food and try to eat it. The California Coastal Commission web site (http://www.coastal.ca.gov/publiced/marinedebris.html) notes that a recent study found an average of 334,271 pieces of plastic per square mile in the North Pacific Central Gyre, which serves as a natural eddy system to concentrate material. Results of more than 10 years of volunteer beach cleanup data indicate that 60 to 80 percent of beach debris comes from land-based sources. Plastic marine debris affects at least 267 species worldwide, including 86 percent of all sea turtle species, 44 percent of all sea bird species, and 43 percent of marine mammal species. (Note: this research has been documented by the Algalita Marine Research Foundation in Our Synthetic Sea, a video available at http://algalita.org/videos.html.

Plastics and Marine LifeThe potential for ingestion of plastic particles by open ocean filter feeders was assessed by the Algalita Marine Research Foundation by measuring the relative abundance (number of pieces) and mass of floating plastic and zooplankton near the central high-pressure area of the North Pacific central gyre. (The gyre is a large recirculating area of water halfway between Los Angeles and Hawaii.) Plankton abundance was approximately five times higher than that of plastic, but the mass of plastic was approximately six times that of plankton. This area is far from land, and many types of marine life feed here. The effects of plastics on marine life can be devastating. Aquatic animals may be harmed by plastic objects in a variety of ways, depending on the shape and buoyancy of the object. These animals may suffer injury or even death from their encounters with plastics. Animals can be harmed through entanglement, laceration, suffocation, and ingestion.

The buoyant properties of water allow some plastics to float, some to sink, and some to stay in the water column. The types of plastics marine animals may come into contact with depend upon where they live and eat: at the water’s surface, its bottom, or floating in the water column between the surface and bottom.

PROCEDURE1. Introducing Marine Debris: Use ideas from the Voyage to Kure

Viewing Guide to set the scene. Pay particular attention to the Segment Suggestions for the marine debris theme (film clips from Laysan Island and Midway Atoll). If you do not have access to the Voyage to Kure episode, try to find pictures of marine debris to show to students and lead a discussion about the danger to animals and ecosystems. What do students think about plastics in the ocean? Where does plastic go? Does it go away? What types of animals are most affected?

2. Class Discussion: Continue class discussion by exploring the many ways we use plastics in our daily lives.

3. Plastics Handout and Discussion: Pass out Plastics and Their Uses student handout and discuss the different types of plastics. Note that most cities only accept Society of the Plastics Industry (SPI) codes 1 and 2 for recycling. Although many of the other types of plastic are labeled as “recyclable,” in reality, this does not occur and the majority of plastics end up in landfills.

4. List Types of Plastics: From water bottles to computers, we rely on the convenience and availability of plastics to provide many of today’s necessities. List on the board the shapes that plastic can come in, and have students give examples of what they are used for:One-dimensional objects (line, rope, strapping bands)Two-dimensional objects (sheets, bags)Reticulated (netting, six-pack rings)Hollow-bodied (bottles, fishing floats)Small particles (Styrofoam, pellets used in making plastic objects)Angular (boxes, crates)

5. Discuss Marine Zones: Discuss the marine zones in which animals feed (surface, pelagic, and benthic). Have students brainstorm what types of animals might live and feed in each of these zones.

You Are What You Eat: Plastics and Marine Life

6. Form Groups, Distribute Handouts: Either divide the class into small groups (3-4 students) or distribute materials to individuals. Distribute copies of the You Are What You Eat student handout, a set of the Marine Animal Cards, and a Marine Animal Feeding Habits and Plastic Risk Chart to groups or individuals.

7. Student Worksheets: Have students read You Are What You Eat and complete the worksheet activity, placing the marine animal cards on their charts. Keep in mind that there are many different possible “right” answers; students primarily need to have a rationale for their choices.

8. Present Rationales: After the groups or individuals have completed the activity, draw the chart on the board. Have each group or student choose one form of plastic (one-dimensional, two-dimensional, small particles, etc.) and present to the class their results and rationale of what species would be most affected. Allow time to propose different answers, discuss them, and wrestle with different conclusions.

9. Reflection: Conduct a class discussion on how to reduce the amount of plastics in the marine environment.

TEACHER NOTES• Here are some possible worksheet answers. Your students may

have additional answers with plausible rationales. This is an area of active scientific investigation; we have yet to learn the extent of devastation caused by plastic marine debris.

Answer Key: Marine Animal Feeding Habits and Plastic Risk

EXTENSIONS• Have students bring different types of plastic trash from home, or

use the trash from their lunches. Conduct buoyancy experiments to see which pieces float, which sink, and which are neutrally buoyant. Group like objects together based on buoyancy. Now check their recycle number on the bottom—the number in the triangle. Do all types of plastic with the same number have the same buoyancy? What might affect the buoyancy besides the type of plastic (e.g. the shape of the object)?

Ocean Literacy: Essential Principles and Fundamental Concepts(http://coexploration.org/oceanliteracy/)

Essential Principle #5: The ocean supports a great diversity of life and ecosystems.e. The ocean is three-dimensional,

offering vast living space and diverse habitats from the surface through the water column to the seafloor. Most of the living space on Earth is in the ocean.

f. Ocean habitats are defined by environmental factors. Due to interactions of abiotic factors such as salinity, temperature, oxygen, pH, light, nutrients, pressure, substrate and circulation, ocean life is not evenly distributed temporally or spatially, i.e., it is “patchy”. Some regions of the ocean support more diverse and abundant life than anywhere on Earth, while much of the ocean is considered a desert.

• Get a list from your local refuse agency that indicates what plastics they accept for recycling, and sort your plastic trash from the preceding extension activity accordingly. Are the recyclable plastics primarily floaters or sinkers? Do you think that the plastic that is more easily recyclable ends up in the ocean less often than those that are not recyclable in your area? Which ocean animals might recycling plastic help most?

Essential Principle #6: The ocean and humans areinextricably interconnected.e. Humans affect the ocean in a

variety of ways. Laws, regulations and resource management affect what is taken out and put into the ocean. Human development and activity leads to pollution (point source, non-point source, and noise pollution) and physical modifications (changes to beaches, shores and rivers). In addition, humans have removed most of the large vertebrates from the ocean.

g. Everyone is responsible form caring for the ocean. The ocean sustains life on Earth and humans must live in ways that sustain the ocean. Individual and collective actions are needed to effectively manage ocean resources for all.

You Are What You Eat

Do different forms of plastic affect animals feeding in different parts of the ocean? Here is some information that will help you answer this question and fill out your Marine Animal Feeding Habits and Plastic Risk chart.

The Three Marine ZonesScientists divide bodies of water into three basic areas:

1. The surface zone: the very surface of the water where it meets the air and things float where you can see them.

2. The pelagic zone: the open water below the surface where neutrally buoyant fish swim and plankton float.

. The benthic zone: what lies beneath the bottom of the water; consists of mud, sand, or rock.

Where Marine Life EatsDifferent forms of marine life gather their food in different zones. For example, some birds are surface feeders. They skim along just above the ocean’s surface, and scoop up small bits of floating fish. Many fish are pelagic feeders. They swim about, eating smaller animals, plankton, and other food that share the water with them. Many whales, turtles, seals, and diving birds are pelagic feeders. Other kinds of fish, turtles, whales, and sea otters swim along the bottom to scoop up food from the ocean floor. They are called benthic feeders. Animals that feed in different areas of the ocean often interact with different forms of plastic. For example, a bird skimming the ocean surface might accidentally scoop up bits of floating plastic pellets thinking they were food, but wouldn’t scoop up a large, floating, angular object such as a Styrofoam ice chest, or a hollow object such as a plastic bottle.

Activity Directions1. Arrange each card in your packet on the chart so that the

animals are: • Located under the form of plastic they will have trouble

with, and• Next to the zone where they feed

2. Then, take the card off of the square and write the animal’s name in the square. One animal may be affected by more than one type of plastic, and may feed in more than one habitat, so there will likely be more than one animal name in a square.

3. You will compare charts with other students. Be sure to be able to explain your rationale for placement.

Voyage to Kure Viewer Guide“We must restore much of Earth from our impact, but these faraway jewels of the sea still thrive with life.

We need only protect them from human harm, and let them be.” —Jean‑Michel Cousteau

In this two‑hour program, Jean‑Michel Cousteau leads an expedition to the Northwestern Hawaiian Islands (NWHI). They are the most remote islands on the planet and serve as reminders of what many other reefs used to be, crowded with wildlife and nearly unspoiled. Their isolation, however, has not been able to protect them completely. Voyage to Kure chronicles Jean‑Michel’s exploration of this nearly pristine environment and his investigation to uncover the stories of its native people and its exploitation by outsiders.

PRE-VIEWING ACTIVITIES• Brainstorm all the ways you as an individual affect the

environment—both positively and negatively—as well as things you can do differently to lessen your negative effects and increase your positive effects.

• Hypothesize as to whether your actions have any affect on the ocean.

• Look at a map to locate all of the ocean basins of our one ocean. Find the NWHI chain on a map. How do you think you might affect this environment?

• Trace the path of man‑made debris from land to sea; investigate how your watershed is connected to the ocean.

• Read the detailed episode description; pay particular attention to the vocabulary words and record them on the Ocean Vocabulary Sheet.

FOCUS FOR VIEWING• Use the Voyage to Kure viewing questions that go with the

segments you watch.

THEMEProtection and maintenance of the ocean, including mechanisms for addressing pollution/marine debris and invasive species

VIEWING TIMETwo hours total; viewing it in shorter segments is recommended

OBJECTIVES Students will be able to• locate ocean basins and the

NWHI on a map.• identify positive and negative

impacts humans have on the ocean and the NWHI and propose ways to lessen the negative impacts and increase the positive impacts.

Ocean Literacy: Essential Principles and Fundamental Concepts http://coexploration.org/oceanliteracy/

Essential Principle #1: Earth has one big ocean with many features. a. The ocean is the dominant

physical feature on our planet Earth, covering approximately 70 percent of the planet’s surface. There is one ocean with many ocean basins, such as the North Pacific, South Pacific, North Atlantic, South Atlantic, Indian and Arctic.

h. Although the ocean is large, it is finite and its resources

are limited.

Page 43: Marine Debris and its Effects on the NWHI · 2017-08-17 · • Students will learn how different feeding techniques of Sea Birds of the NWHI determine what types of Marine Debris

Voyage to Kure Viewer Guide

Essential Principle #6: The ocean and humans are inextricably interconnected.b. From the ocean we get foods,

medicines, and mineral and energy resources. In addition, it provides jobs, supports our nation’s economy, serves as a highway for transportation of goods and people, and plays

a role in national security.c. The ocean is a source of

inspiration, recreation, rejuvenation and discovery. It is also an important element in the heritage of many cultures.

e. Humans affect the ocean in a variety of ways. Laws, regulations and resource management affect what is taken out and put into the ocean. Human development and activity leads to pollution (point source, nonpoint source and noise pollution) and physical modifications (changes to beaches, shores and rivers). In addition, humans have removed most of the large vertebrates from the ocean.

g. Everyone is responsible for caring for the ocean. The ocean sustains life on Earth and humans must live in ways that sustain the ocean. Individual and collective actions are needed in order to effectively manage ocean resources for all.

Post-Viewing Discussion Questions: • Review answers from the Viewing Questions handout.• Describe some of the problems that invasive species cause.

Follow-up Activity: • The Purple Problem: in this lesson, students will learn

about purple loosestrife and the problems it causes as an invasive species.
