Sea Kayak Marine Debris Cleanup: Restoring Wilderness Shorelines in the Gulf of Alaska

Even though Shuyak Island State Park is a remote wilderness island in the northern Gulf of Alaska, it has been heavily impacted by marine debris. Through a community-based removal grant project funded by the NOAA Marine Debris Program, Island Trails Network (ITN) led 29 volunteers from June 12th to September 4th of this year to help remove marine debris in this area. There were six teams of five to seven sea paddlers, which each spent two weeks camping and collecting debris to restore coastal habitats on Shuyak. During 56 total days of cleanup, we collected 35,036 pounds of marine debris from a continuous belt of coastal habitat (52 miles in length) along the island’s northwest shore. Cleanup teams moved freely along the coast in sea kayaks, which were a convenient means of accessing shallow rocky shorelines.

Removing Debris in Tenakee Springs, Alaska: A Look Back

Over the years of the NOAA Marine Debris Program, there have been many efforts around the country to rid our waters and shores of marine debris. As part of our ten-year anniversary celebration, let’s take a look back at one of those efforts in Alaska.

Back in 2012, the community of Tenakee Springs, Alaska received funding from the NOAA Marine Debris Program to remove debris in their remote community. Tenakee Springs, with less than 100 residents, sits about 50 air miles from Juneau in Southeast Alaska and is inaccessible by road. In fact, there are no roads at all in the town, just a long, wide trail that people use to get around via foot, bike, or four-wheeler.

Marine Debris Research: What Happens When Salmon Eat Foamed Plastic?

After the 2011 tsunami in Japan, the Alaskan coastline experienced a rise in debris washing ashore. Although there was an increase in many types of debris, the abundance of expanded polystyrene (think foamed plastic) increased on some beaches by as much as 1,600% from 2008 to 2012. This spurred interest by NOAA scientists at the Auke Bay Laboratory in Juneau, Alaska, to explore the interaction between this foam debris and an important Alaskan fishery species: pink salmon (Oncorhynchus gorbuscha). The researchers were interested in both determining the potential of juvenile pink salmon to ingest small foam pieces and understanding the physiological consequences of ingesting foam debris (such as, would ingesting foam alter their growth rates?). Through support from the NOAA Marine Debris Program, the team began an experimental study to address these questions.

Removing Marine Debris in Alaska

Although preventing marine debris is the ultimate solution, removing debris as it accumulates on our shores is an unfortunate necessity. In Alaska, there are currently some pretty cool removal efforts underway to clean up Alaska’s coasts, which are often remote and difficult to access.

The Island Trails Network (ITN) is addressing the issue of debris in remote areas in an innovative and unique way! This effort focuses on Shuyak Island, an area rich in biodiversity that’s located in the western Gulf of Alaska. This location is exposed to high winds and strong currents that cause marine debris to build up, but also make it difficult to access. To solve this problem, ITN recruited qualified volunteers from around the world to come to Alaska and clean the shoreline using sea kayaks, collecting debris and moving it to more easily-accessible areas, where it is later removed and analyzed.
