The marine debris data included in this dataset are from annual in-water surveys conducted from 1999 to 2021 at the reefs, atolls and islands in the Northwestern Hawaiian Islands (NWHI) by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) with funding from Papahanaumokuakea Marine National Monument (PMNM), and NOAA's Marine Debris (MDP) and Damage Assessment Remediation and Restoration (DARRP) Programs.
These surveys and removal efforts of marine debris were conducted primarily during ship-based missions to the NWHI, and also as fly-in missions. During a mission, surveys were conducted by divers based on small boats launched either from a ship or from the shore. Two survey methods were used to search for marine debris; tow and swim surveys. Tow surveys were used in the relatively even-depth (usually less than 10 meters deep), contiguous backreef habitats, typically at Midway Atoll, Kure Atoll and Pearl and Hermes Atoll. Two free-divers were towed behind a small boat to search for debris throughout the water column. Swim surveys were used primarily in the comparatively high-relief and patchy lagoonal reef habitats of Maro Reef and Pearl and Hermes Atoll. During swim surveys, two or more snorkelers swam across the reefs to search for debris while being directed by the small boats to follow pre-planned routes. Survey areas and routes were chosen based on regional reef morphology and past debris accumulation records.
During a survey, if debris larger than 0.012 cubic meters (size of a small toolbox) was encountered, descriptive information about the debris and its location (i.e., type, color, size, biofouling, estimated depth, substrate composition/color) were recorded and a GPS waypoint was taken. Debris was removed if determined to be safe to do so and without causing damage to the surrounding coral reef habitat. Once removed, the volume of removed debris was estimated and recorded. At the end of the survey or if the small boat reached its capacity, the boat returned to the ship or to the shore and the boats debris load was weighed and recorded. Up to 4 small boats in one day concurrently conducted surveys during a mission.

| Abstract: |
The marine debris data included in this dataset are from annual in-water surveys conducted from 1999 to 2021 at the reefs, atolls and islands in the Northwestern Hawaiian Islands (NWHI) by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) with funding from Papahanaumokuakea Marine National Monument (PMNM), and NOAA's Marine Debris (MDP) and Damage Assessment Remediation and Restoration (DARRP) Programs. These surveys and removal efforts of marine debris were conducted primarily during ship-based missions to the NWHI, and also as fly-in missions. During a mission, surveys were conducted by divers based on small boats launched either from a ship or from the shore. Two survey methods were used to search for marine debris; tow and swim surveys. Tow surveys were used in the relatively even-depth (usually less than 10 meters deep), contiguous backreef habitats, typically at Midway Atoll, Kure Atoll and Pearl and Hermes Atoll. Two free-divers were towed behind a small boat to search for debris throughout the water column. Swim surveys were used primarily in the comparatively high-relief and patchy lagoonal reef habitats of Maro Reef and Pearl and Hermes Atoll. During swim surveys, two or more snorkelers swam across the reefs to search for debris while being directed by the small boats to follow pre-planned routes. Survey areas and routes were chosen based on regional reef morphology and past debris accumulation records. During a survey, if debris larger than 0.012 cubic meters (size of a small toolbox) was encountered, descriptive information about the debris and its location (i.e., type, color, size, biofouling, estimated depth, substrate composition/color) were recorded and a GPS waypoint was taken. Debris was removed if determined to be safe to do so and without causing damage to the surrounding coral reef habitat. Once removed, the volume of removed debris was estimated and recorded. At the end of the survey or if the small boat reached its capacity, the boat returned to the ship or to the shore and the boats debris load was weighed and recorded. Up to 4 small boats in one day concurrently conducted surveys during a mission. |
| Purpose: |
The purpose of the marine debris survey and removal efforts in Northwestern Hawaiian Islands is to mitigate entanglement threats to wildlife, in particular to the critically endangered Hawaiian monk seal (Monachus schauinslandi) and the threatened green sea turtle (Chelonia mydas) and to reduce the impact on coral reef habitats. Also, the focused effort to survey the debris in the backreef areas in Midway Atoll aims to study rates of debris accumulation in this remote location. |
| Notes: |
During an extended field season at Midway Atoll in the NWHI in 2012, PIFSC scientists removed all of the marine debris along the backreefs at Midway Atoll. This represented a starting point to begin studying the accumulation rate along the backreefs for subsequent years. Since then there have been focused efforts to survey and study the accumulation rate in Midway Atoll. In 2013, 2015, 2018, and 2021 the survey and removal efforts were conducted as a component of the shore-based mission at Midway Atoll. Prior to the surveys in 2013, the backreef areas of the atoll were divided into 35 fixed survey boxes (size of each survey box is approximately 0.25 km2). Because of limited survey time, the preexisting survey boxes were randomized, and a subset of the boxes were identified as a first- or second-tier priority for each strata to survey. During a shore-based mission, when a small boat is at its capacity, the boat returns to Sand Island of Midway Atoll to weigh and record its debris load. |
| Supplemental Information: |
The Papahanaumokuakea Marine National Monument (PMNM) includes the 1200 nautical mile chain of atolls and islets known as the Northwestern Hawaiian Islands (NWHI) that are geographically positioned as a repository for marine debris. 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 cruises deployed up to 4 months at a time with a team of up to 18 personnel. The efforts prior to 1999 were focused on the removal of the marine debris, therefore data collection was inconsistent and not standardized. 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). |

Data Quality
| Accuracy: |
Prior to conducting surveys, researchers are trained to identify debris type and estimate/measure debris size, along with other ecological metrics. Both classroom and field training tests must be completed for all researchers (experienced and inexperienced alike) before each round of surveys begins. This training ensures that all marine debris surveys are conducted consistently by all researchers during a mission and from year to year. Handheld GPS units were used to record the location/coordinate for each debris item. |
|---|---|
| Comparability: |
The primary objective of the efforts in the earlier years (1999 to ~2009) was removal of marine debris, and the survey and data collection was the secondary objective. Therefore, data was not captured as consistently during this time period compared with the more recent surveys. |
| Completeness Report: |
Only shallow water (0 to ~10 meter depth range) habitats are surveyed. The survey sites/islands/atolls were identified and selected as high-density debris accumulation areas by looking at historical debris point data and assessing reef characteristics (depth, benthic habitat type, and energy regime). Previously cleaned backreef and lagoonal reefs were resurveyed for accumulated debris. |
| Quality Control Procedures Employed: |
Size estimates of debris in water were verified against the more accurate volume estimates of the nets once removed from the shallow coral reef environments and hauled onto the small boats. |

Lineage
| Lineage Statement: |
Marine debris removal has been conducted by the Pacific Islands Fisheries Science Center's Ecosystem Sciences Division at the atolls, reefs and islands of Northwestern Hawaiian Islands since 1996. Standardized data collection has been implemented since 1999. Two methods are used to survey for marine debris; tow and swim surveys. Tow surveys are typically used in the relatively even-depth (usually less than 10 meters deep), contiguous backreef habitats, while swim surveys are typically used in the comparatively high-relief and patchy lagoonal reef habitats. Survey areas are chosen based on regional reef morphology and past accumulation records. |

Process Steps
Process Step 1
| Description: |
The towed-diver surveys are used in areas of relatively flat bathymetry less than 10 meters in depth (primarily the contiguous backreef habitats that lie just inside the surf on the lagoon-side of the barrier reef of an atoll) as found at Midway Atoll, Kure Atoll and Pearl and Hermes Atoll. In this method, two free-divers are towed behind a small-boat at speeds of 1-2 knots on a towboard (underwater wing) to search for debris and/or derelict fishing gear snagged on the reef. Divers hold their breath, submerge below the surface and conduct a back-and-forth pattern across the reef visually scanning for marine debris. These surveys cover areas that include depths of 0.5-10 m over hard or mixed hard/soft substrate. The boat conducts a “lawn-mowing pattern†back and forth across the reef and records a trackline with the GPS. When calculating area surveyed on GIS, the boat’s trackline is buffered out 7.5 meters on either side to represent the area each diver is able to reasonably visually survey. *Note: Divers measure water visibility at the start and end of each operational day. A minimum visibility measurement of 7.5 m is required to conduct towed-diver surveys. |

Process Step 2
| Description: |
The swim survey method was developed as a necessary alternative to towed-diver surveys in lagoonal, reticulated reef areas that were either too shallow, too irregular, or high-relief habitats difficult to survey effectively with the towed-diver survey technique. The method has typically been used in Maro Reef and Pearl and Hermes Atoll. During swim surveys, two or more divers swim across reefs to search for debris while being directed by the personnel in small boats to follow pre-planned routes and are coordinated for maximum visual area covered. Survey areas and routes are chosen based on regional reef morphology and past accumulation records. |

Process Step 3
| Description: |
When a diver encounters debris larger than 0.012 cubic meters (size of small toolbox), descriptive data about the debris such as type, color, size, foul level, presence/absence of coral growth on the debris, estimated depth of debris, and substrate composition/color surrounding the debris are recorded. The location of the debris where it was found is also recorded with a GPS. The debris is removed (cut from the reef or pulled out of the sand) when it is determined that it is safe to do so, and that removing the debris won't cause harm to the surrounding corals. Once removed and loaded into the cargo area of the small boat, the volume of removed debris is recorded. |

Process Step 4
| Description: |
When a small boat is at its capacity, the boat returns to the parent vessel and the debris load for the boat is weight and recorded. Typically 3 to 4 small boats are used per day for the underwater surveys. Areas surveyed for each boat are derived from GPS tracks. |

Process Step 5
| Description: |
In 2013 and 2015, the survey and removal efforts were conducted as a component of the shore-based mission at Midway Atoll. Prior to the surveys in 2013, the backreef areas of the atoll were divided into 35 fixed survey boxes (size of each survey box is approximately 0.25 km2). Because of limited time available, the preexisting survey boxes were randomized, and a subset of the boxes were identified as a first- or second-tier priority for each strata to survey. During a shore-based mission, when a small boat was at its capacity, the boat returned to Sand Island at Midway Atoll to weigh and record its debris load. |

Process Step 6
| Description: |
Individual weight of each removed debris can be estimated using WEIGHTLOAD_KG and VOLUME_REMOVED fields of each of the entities. First the VOLUME_REMOVED is summed for each GPS_FILE_DATE, WEIGHTLOAD_KG and LOAD_NUM to derive a total volume of debris removed for a load of a boat for a survey date. Fraction of each volume of debris removed is derived from dividing each VOLUME_REMOVED record by the associated total volume of debris debris removed for the load. Individual weight for each debris can be derived from multiplying the fraction by the WEIGHTLOAD_KG for the load. |
