Prior to the surveys in 2013, each shoreline was divided into fixed 300-meter segments and stratified by the cardinal direction the shoreline was facing (e.g., north, south, east, and west). The shorelines of Eastern, Spit, and Sand Islands were divided into 19, 4, and 23 segments, respectively. All segments were surveyed at all islands during the 2013, 2015, and 2016 missions. During the 2014 mission, limited time was available to survey all segments; therefore, the pre-existing segments were randomized, and a subset of the segments were identified as a first- or second-tier priority for each strata. All first- and second-tier priority segments were surveyed in 2014. All first- and second-tier priority segments at Eastern and Spit were surveyed in 2018. During a shoreline survey, field staff flagged the corners of the site and swept the entire survey area for marine debris. Most items found within the survey area >10 cm were collected and, if possible, bagged. Due to operational concerns, metal, glass, and building material were not surveyed or removed. Debris items <10 cm were also collected and bagged if the item could be identified (e.g., bottle caps and lighters were included in the survey, unidentified fragments <10 cm were typically excluded). Additionally, if the debris item was considered large (>1 m) or notable, a GPS waypoint was taken to mark the specific location of the debris, and the item was measured (length and width), recorded on the datasheet, and either bagged, removed, or tagged if the item was too large or hazardous to remove. The survey concluded by walking the perimeter of the survey site with a GPS. Following the survey, bagged and large debris were transported to the operations center for the mission, weighed, and sorted, tallied, and recorded by debris type for each survey. Total weight of all collected debris and the survey area (derived from the GPS tracks) were recorded for each 300-m segment, along with the date since the last debris survey to calculate the accumulation rate. During an extended field season at Midway Atoll in the NWHI in 2012, PIFSC scientists removed all of the marine debris along the shorelines of the islands at Midway Atoll. This represented a "clean slate" and starting point to begin studying the accumulation rate along the shorelines for subsequent years. Accumulation rates are reliable only for Eastern and Spit Islands. The shorelines of Sand Island are cleaned regularly by permanent U.S. Fish and Wildlife Service residents; thus, the debris data recorded by ESD for Sand Island does not represent natural accumulation. The shoreline survey and removal efforts at Midway Atoll have been conducted as a component of ship-based missions to the NWHI, a component of a larger shore-based missions at Midway Atoll, or as a stand-alone shoreline debris removal mission at Midway Atoll. The purpose of the marine debris survey and removal efforts at Midway Atoll is to mitigate entanglement threats to wildlife and study the accumulation rates at Midway Atoll's three islands: Sand, Eastern, and Spit.

Marine debris circulates within the North Pacific Subtropical Gyre until it encounters the atolls of the NWHI. The Ecosystem Sciences Division (ESD) at the NOAA Pacific Islands Fisheries Science Center (PIFSC) has conducted both ship- and shore-based missions in the NWHI to survey for and remove derelict fishing gear and many other types of marine debris. Exploratory and opportunistic efforts began in 1996 that eventually evolved into annual dedicated cruises deployed up to 4 months at a time with a team of up to 18 divers. These marine debris missions have been supported by several agencies over the years, including PMNM, NOAA Marine Debris Program (MDP), NOAA Damage Assessment Remediation and Restoration Program (DARRP), and the NOAA Coral Reef Conservation Program (CRCP). ESD has removed derelict fishing gear and other marine debris from Pearl and Hermes Atoll (PHR), Midway Atoll (MID), Kure Atoll (KUR), Lisianski Island (LIS), Laysan Island (LAY), Maro Reef (MAR), and French Frigate Shoals (FFS). false eng false Data Table Large Debris Entities from Shoreline Surveys 2024-03-13 publication Debris Entities from Shoreline Surveys 2024-03-13 publication CSV - Comma Separated Values (Text) Uncompressed CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact WWW:LINK-1.0-http--link NCEI Contact Information Information for contacts at NCEI. information distributor https://accession.nodc.noaa.gov/0189571 WWW:LINK-1.0-http--link ESD_Shoreline_LargeDebris_MID_2013-2018.csv Large (>1 m in length or width) or notable marine debris collected during shoreline surveys at Midway Atoll in the Northwestern Hawaiian Islands from 2013-2018 by the PIFSC Ecosystem Sciences Division. download https://accession.nodc.noaa.gov/0189571 WWW:LINK-1.0-http--link ESD_Shoreline_Debris_MID_2013-2018.csv Marine debris collected during shoreline surveys at Midway Atoll in the Northwestern Hawaiian Islands from 2013-2018 by the PIFSC Ecosystem Sciences Division. download https://accession.nodc.noaa.gov/0189571 WWW:LINK-1.0-http--link ShorelineFieldGuide2012.pdf NOAA Marine Debris Shoreline Survey Field Guide, published in January 2012 by the NOAA Marine Debris Program and used by Pacific Islands Fisheries Science Center, Ecosystem Sciences Division to conduct shoreline surveys at Midway Atoll. download dataset Accuracy Prior to conducting surveys, scientists are trained to identify fisheries-specific debris items (derelict fishing gear, nets, floats, buoys, FADs, oyster spacer tubes, eel cone traps, etc.) and common everyday consumer plastic debris items. Both classroom and field training tests must be completed for all researchers (experienced and inexperienced alike) before a new round of surveys begin. This training ensures that all shoreline marine debris surveys are conducted consistently by all scientists within a survey effort and also across periodic survey efforts. Completeness Report The shorelines of East and Spit Islands of Midway Atoll were divided into 300 meter segments. The shoreline debris survey segments were randomly selected to ensure accuracy when calculating shoreline marine debris accumulation rates. Previously cleaned shorelines were resurveyed for accumulated debris. Conceptual Consistency The same methods of data collection were conducted consistently at each of the sites surveyed, by all scientists within survey efforts and across periodic survey efforts since. Shoreline debris surveys conducted by the Pacific Islands Fisheries Science Center's Ecosystem Sciences Division along the shorelines of the three islands on Midway Atoll: Sand, Eastern, and Spit since 2013. Prior to the surveys in 2013, each shoreline was divided into fixed 300-meter survey segments and stratified by the cardinal direction the shoreline was facing (e.g., north, south, east, and west). The shorelines of Eastern Island, Spit Island, and Sand Island were divided into 19, 4, and 23 segments, respectively, and the segments were randomly selected (to ensure accuracy when calculating shoreline marine debris accumulation rates). All shoreline segments are typically surveyed during each annual mission. Accumulation rates are calculated for previously cleaned survey segments that are resurveyed in subsequent years for newly accumulated debris. Morioka, James M (808)725-5491 james.morioka@noaa.gov processor During a shoreline survey, field staff flagged the corners of the site and swept the entire survey area for marine debris. Most items found within the survey area >10 cm were collected and, if possible, bagged. Due to operational concerns, metal, glass, and building material were not surveyed or removed. Debris items <10 cm were also collected and bagged if the item could be identified (e.g., bottle caps and lighters were included in the survey, unidentified fragments <10 cm were typically excluded).

Morioka, James M (808)725-5491 james.morioka@noaa.gov processor Following the survey, bagged and large debris were transported to the operations center for the mission, weighed, and sorted, tallied, and recorded by debris type for each survey. The NOAA Marine Debris Program-standardized shoreline survey datasheet was used to tally different debris types. Eel traps, oyster spacers, plastic pipes, and plastic baskets were added to the debris type categories (a significant number of these were found during the shoreline surveys). Large and notable items were individually weighed and recorded separately. Total weight of all collected debris and the survey area (derived from the GPS tracks) were recorded for each 300-m segment, along with the date since the last debris survey to calculate the accumulation rate.
