Tasked with providing scientific information for Park decision-making, ARCN identified fish as a key vital sign for ecological monitoring because fish play an essential role in these park ecosystems \u2014 they are a primary food source for Indigenous communities living in and near the region, they occupy critical positions within aquatic food webs, and they often serve as top predators in lakes and streams. Moreover, fish are highly susceptible to climate change, which poses a significant threat to Arctic ecosystems worldwide. Despite their ecological and cultural importance, limited data exist on fish populations within the Arctic Network. To address this gap, the dataset described here provides baseline information on fish in GAAR, consisting of capture data collected from the Noatak River in Gates of the Arctic National Park and Preserve between July 15 and 26, 2005 (Bowden et al., 2005).\n\nKey words\nFish, Alaska, Gates of the Arctic, Noatak,Arctic grayling,Lake trout,Nine-spine stickleback,Northern pike,Round whitefish,Spiny sculpin,Anorat Creek,Kipmik Lake,Komakak Creek,Kugrak Spring,Lake Matcharak,Nushralutak Creek,Oyukak Creek\n\nFiles in this Release\nThis data release consists of two data files:\n\n2005 GAAR Fish Sampling.csv\n\n2005 GAAR Fish Sampling.csv_Metadata.csv\n\nMetadata\nColumn names, descriptions and units of measure for the data file 2005 GAAR Fish Sampling.csv appears in Table 1.\n\nTable 1.\n\nColumnName\tDataType\tDescription\tUnitsOfMeasure\nDate\tDate\tDate.\t\nName\tcharacter\tFormal name, if known.\t\nCommonName\tcharacter\tCommon name.\t\nTL (mm)\tnumeric\tDescription unknown.

Sampling intensity was documented in terms of person-hours or net-hours. Length (mm) and weight (g) measurements were recorded for many, though not all specimens. Sampling locations were recorded in numerous cases, but for others, no location data exists other than unofficial names. Sampling intensity was likely not sufficient to determine a complete list of fish species for any site.\n\nStudy Area\nFish were sampled in water bodies, mostly in the Noatak River basin in Gates of the Arctic National Park and Preserve, Alaska, U.S.A.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://irma.nps.gov/DataStore/DownloadFile/743489?Reference=2314959", "format": "csv", "mediaType": "text/csv", "title": "2005 GAAR Fish Sampling.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://irma.nps.gov/DataStore/DownloadFile/743490?Reference=2314959", "format": "csv", "mediaType": "text/csv", "title": "2005 GAAR Fish Sampling.csv_Metadata.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://irma.nps.gov/DataStore/DownloadFile/743491?Reference=2314959", "format": "html", "mediaType": "text/html", "title": "GAAR_2005_FishSampling.html"}], "identifier": "http://datainventory.doi.gov/id/dataset/NPS_DataStore_2314959", "issued": "2025-07-29T00:00:00Z", "keyword": ["Alaska", "Anorat Creek", "Arctic grayling", "Fish", "Gates of the Arctic", "Kipmik Lake", "Komakak Creek", "Kugrak Spring", "Lake Matcharak", "Lake trout", "Nine-spine stickleback", "Noatak", "Northern pike", "Nushralutak Creek", "Oyukak Creek", "Round whitefish", "Spiny sculpin"], "landingPage": "https://irma.nps.gov/DataStore/Reference/Profile/2314959", "modified": "2025-07-29T00:00:00Z", "programCode": ["010:118", "010:119"], "publisher": {"@type": "org:Organization", "name": "National Park Service"}, "spatial": "-155.904358,66.6496353,-149.52887,68.43901", "theme": ["geospatial"], "title": "Fish Sampling in Gates of the Arctic National Park and Preserve, July, 2005"}
