Talking Trash

The Problem With Marine Debris

Slide2 l.jpg

Marine Debris: What is it?

Any unnatural items that makes it

way into our ocean or marine environment

Directly (i.e. dumping)

Indirectly (i.e. street litter washing out to sea

Slide3 l.jpg

30-40% of debris originates from

ships at sea

Estimated that 5 million items of marine litter are thrown overboard or lost from ships everyday

Over 46,000 pieces of plastic litter are believed to be floating on every square mile of ocean

Derelict Fishing Gear

Glass, Metal, Styrofoam, and Rubber

Derelict Vessels

Types of Marine Debris

The Movement of Marine Debris

Slide7 l.jpg

Problems with Marine Debris

Slide8 l.jpg

Wildlife Entanglement



Both can lead to death

Slide9 l.jpg

Affects seals, whales, turtles, fish, seabirds

Slide10 l.jpg

Destruction of Marine Habitat

Breakage and smothering of coral reefs

Divers can remove nets…

but the reef is already damaged…

Slide11 l.jpg

Transportation of Non-Indigenous Species

Diadumene lineata: an invasive intertidal anemone

Slide12 l.jpg

Navigational Hazards that may cause Vessel Damage

Large accumulations of derelict fishing gear can:

Damage a vessel

Entangle the propellor

Result in a navigational hazard

Result in a safety risk for those onboard

Slide14 l.jpg

Marine Debris Can be Toxic

Persistent organic pollutants (POPs): a class of chemicals that can be released by ordinary garbage

Extremely toxic, even at low concentrations

Accumulate in the fatty tissues of marine mammals

POPs have been shown to disrupt hormones that could result in cancer and birth defects

Slide15 l.jpg

What’s being done?

Slide16 l.jpg

NOAA's Marine Debris Program


A national effort to





marine debris

Slide17 l.jpg


protect and conserve

our nation’s natural resources and coastal waterways from the impact of marine debris

Promotes: research, monitoring,

outreach, and reduction outcomes

Slide18 l.jpg

NOAA’s marine debris program

2006: first ever comprehensive project to survey and remove marine debris in the main Hawaiian Islands.

Aerial surveys of all main islands

Slide19 l.jpg

ID’ed over 700 debris sites and approx. 129 tons of debris

Waiohinu-ka Lae Coastline, Big Island

Kanapou Bay, Kaho’olawe

42 tons in 9 miles

5 tons in ¼ mile

How you can help

Get involved in local clean-ups

Don’t litter; find a trash can

Leave your favorite places cleaner than when you got there; bring a trash bag with you when you go to the beach

Reduce the amount of waste you produce and recycle when you can
