It’s almost World Migratory Bird Day! Coming up on Saturday, May 9, we are working with Environment for the Americas to raise awareness on the importance of migratory bird species and celebrate the ways they connect our world. Unfortunately, the world of birds and people can collide in the ocean and Great Lakes, where marine debris can be found in even the most remote places, including far-off islands where seabirds find shelter and breeding grounds.
Just imagine having the opportunity to wake up every day to the sound of waves, a myriad shades of blue, and warm, salty breezes…For an islander, there is no place you’d rather be! But what happens when nature shows its other face? The NOAA Marine Debris Program’s Florida and the Caribbean and Pacific Islands Regions include island communities that are uniquely impacted by natural disasters. Tropical islands are highly vulnerable to the impact of hurricanes and typhoons for many reasons, and one dangerous consequence is the amount of marine debris that is generated.
Did you know that a category 3 hurricane can produce over 70 million cubic yards of debris? That’s about 31 football stadiums worth of debris! If the debris is near shorelines or waterways, it can end up in the water as marine debris. Removing that much debris is a difficult and expensive process, and it can be difficult to know how to get started. That’s why the NOAA Marine Debris Program is participating in Hurricane Preparedness Week and working with coastal states and U.S. territories to help communities prepare for marine debris after hurricanes.
The Greater Farallones National Marine Sanctuary is one of the NOAA Marine Debris Programs’s longest running Marine Debris Monitoring and Assessment Project partners. Six years of data collection at locations along the Marin, San Francisco, and San Mateo county coastline revealed the types and frequency of marine debris on the surveyed shorelines, as well as one particularly interesting and problematic type of debris. The survey data indicated that shotgun wads, the plastic piece inside a shotgun shell that separates the shot from the powder, are one of the top ten most commonly found plastic items on all surveyed beaches.
Earth Day is a great time to celebrate our ocean, waterways, and Great Lakes, and all of the wonderful things they have to offer. This year, we are showing our appreciation for our favorite places on Earth by announcing the winners of the Annual NOAA Marine Debris Program Art Contest!
Although plastic pollution is not a new phenomenon, concerns over the environmental and human health implications of microplastics, or plastic pieces less than 5 mm in size, has grown rapidly over the past decade. These concerns stem from their potential to be ingested by wildlife, accumulate in animal bodies, and transfer contaminants up the food chain, as well as their widespread presence in the environment.
Microplastics in the ocean are a growing concern to both the scientific community and to the public at large. Much of the attention is focused on the garbage patches that can be found in oceanic gyres and are thousands of miles from their largely urban sources. However, the amount of microplastics is often significantly higher in urban waterways than in these remote garbage patches.
In the environment, animals may be exposed to many stressors at the same time, such as pollution, overfishing, and disease. Research suggests that animals exposed to microplastics and microfibers, or plastic pieces smaller than 5mm in size, may experience negative impacts to their immune system.
