Since beginning in 2012, the NOAA Marine Debris Monitoring and Assessment Project (MDMAP) has brought forth invaluable data, which continues to increase our shared knowledge of marine debris. Partners from around the world have contributed to this dataset by conducting 4,421 surveys at 335 monitoring sites in nine countries. The NOAA Marine Debris Program (MDP) coordinates these efforts, which would not be possible without the dedication of MDMAP partners who lead the charge in collecting data through their passion for the ocean. Both new and experienced MDMAP partner organizations and volunteers contribute time, energy, and resources to expand our understanding of this global issue.

Marine debris is unfortunately an all too frequent sight on our coastlines. A common misconception is that all shoreline debris was left behind by beachgoers. In fact, debris makes its was to the beach from many different sources, including the sea, stormwater runnoff, wind, and nearby river or stream outlets. If you spend time exploring shorelines in different regions, you may notice that the types and amounts of debris are different from place to place (and constantly changing!).

The presence of marine debris creates numerous problems for the environment, marine life, and humans. Large marine debris presents its own unique challenges, threatening the ocean, coasts, and waterways by obstructing navigational channels, causing harm to important habitat, and diminishing commercial and recreational activities. Removing large debris requires significant financial and technical resources.

The NOAA Marine Debris Program works with partners across the country to address marine debris through several nationwide, competitive funding opportunities annually. Over the next few weeks, we will be highlighting community-based marine debris removal and research projects that were awarded grants during the past year.

Setting off and enjoying fireworks to celebrate the Fourth of July is a beloved pastime. During this holiday, the skies light up in brilliant colors and designs, leaving us mesmerized and in awe. Whether lighting up sparklers at home or watching a large colorful aerial production, all fireworks leave behind more than memories, they also result in trash. 

As much as we enjoy beaches for swimming, picnics, and fun in the sun, they are also home to diverse marine and land animals. The Northwestern Hawaiian Islands, Papahānaumokuākea Marine National Monument, is the largest fully protected marine conservation area on the planet. Its shores and land provide an important habitat to many unique animals. The Monument is home to a total of 23 species that are listed under the U.S. Endangered Species Act, including the threatened Hawaiian Green Sea Turtle, endangered Hawaiian monk seal, and the critically endangered Laysan Duck.

Have you ever wondered how much marine debris is on the shoreline of the United States, or what areas of the country have the most debris? What about the most common types of debris in different regions of the United States? These are a few of the questions that were answered by analyzing data from the Ocean Conservancy’s 30-year International Coastal Cleanup, as well as five years’ worth of data from NOAA's Marine Debris Monitoring and Assessment Project.  The NOAA Marine Debris Program funded a rigorous statistical analysis of both datasets performed by the Ocean Conservancy (OC), together with the Commonwealth Scientific and Industrial Research Organisation (CSIRO). We are now pleased to share these exciting results!

The summer is a celebratory time when people gather for graduations, the Fourth of July, weddings, and to enjoy time at the beach. Balloons are often used during these special occasions as decorations and gifts, and are sometimes intentionally released into the air. Unfortunately, once they go up, they must also come down; balloons that are released into the air don’t just go away. There are many decoration alternatives to balloons, such as fabric bunting, lights, paper streamers, plants, and reusable ornaments, which add some flare to any celebration!
