Background

Marine debris

“Marine debris is defined as any persistent solid material

that is manufactured or processed and directly or

indirectly, intentionally or unintentionally, disposed of or

abandoned into the marine environment or the Great

Lakes” (NOAA, n.d.).

“Marine debris is trash and other solid material that

enters oceans and coastal waters and often ends up on

our beaches. It is also known as litter” (EPA, n.d.).

Marine debris

Sources of marine debris include: stormwater drainage,

illegal dumping, lost fishing gear, shipping accidents,

washing or blowing from beaches (Erickson, 2014;

Khairunnisa, Fauziah, & Agamuthu, 2012).

Marine debris presents a hazard to humans and wildlife

(Erickson, 2014; Goldstein, Titmus, & Ford, 2013).
