The refuge lies within the northern boreal subzone of northwestern central Alaska. Six major vegetation classes and 21 subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, upland burn regeneration, subalpine); dwarf scrub (prostrate dwarf shrub tundra, erect dwarf shrub heath, dwarf shrub-graminoid peatland, dwarf shrub-graminoid tussock peatland, dwarf shrub raised bog with scattered trees, dwarf shrub-graminoid marsh); herbaceous (graminoid bog, graminoid marsh, graminoid tussock-dwarf shrub peatland); scarcely vegetated areas (scarcely vegetated scree and floodplain); and water (clear, sedimented). The methodology employed a cluster-block technique. Sample areas were described based on a combination of helicopter-ground survey, aerial photo-interpretation, and digital Landsat data. Major steps in the Landsat analysis involved preprocessing (geometric correction), derivation of statistical parameters for spectral classes, spectral class labeling of sample areas, preliminary classification of the entire study area using a maximum-likelihood algorithm, and final classification utilizing ancillary information such as digital elevation data. The final product is 1:250,000-scale vegetation map representative of distinctive regional patterns and suitable for use in comprehensive conservation planning.</p>","language":"English","publisher":"American Society of Photogrammetry and Remote Sensing","usgsCitation":"Talbot, S., and Markon, C.J., 1988, Intermediate-scale vegetation mapping of Innoko National Wildlife Refuge, Alaska using Landsat MSS digital data: Photogrammetric Engineering and Remote Sensing, v. 54, no. 3, p. 377-383.","productDescription":"7 p.","startPage":"377","endPage":"383","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":298344,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Innoko National Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -158.6041259765625,\n              63.17171454570863\n            ],\n            [\n              -158.6041259765625,\n              63.386600640372414\n            ],\n            [\n              -158.14819335937497,\n              63.386600640372414\n            ],\n            [\n              -158.14819335937497,\n              63.17171454570863\n            ],\n            [\n              -158.6041259765625,\n              63.17171454570863\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"54","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54fec433e4b02419550debc5","contributors":{"authors":[{"text":"Talbot, Stephen S.","contributorId":73266,"corporation":false,"usgs":true,"family":"Talbot","given":"Stephen S.","affiliations":[],"preferred":false,"id":541966,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Markon, Carl J. markon@usgs.gov","contributorId":2499,"corporation":false,"usgs":true,"family":"Markon","given":"Carl","email":"markon@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":false,"id":541967,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The province lies between the displaced continental fragment of Arctic Alaska and the accreted terranes of southern Alaska. Although Lower Cretaceous volcanogenic rocks of the Yukon-Koyukuk province preserve primary remanent magnetizations, the primary component is masked by a pervasive overprint. The over-printing magnetization, which has dual polarity, was acquired after a Late Cretaceous orogeny left the region highly deformed. By fitting planes to tilt-corrected thermal demagnetization data and solving for the best intersection of the corresponding remagnetization circles, we separated the primary component, presumably a vestige of the original thermoremanent magnetization, from the overprinting component of the natural remanence. The primary magnetization corresponds to a mean paleopole of Early Cretaceous age at 60.2°N, 159°E. The mean paleolatitude is 69°N with the 95% confidence ellipse ranging from 60° to 75°N. This analysis was successful because the tilt corrections of the sampled strata had sufficient variation to ensure a strong intersection of the remagnetization circles. We infer that Lower Cretaceous rocks of the Brooks Range and the Yukon-Koyukuk province were once separated by a wide ocean basin that was closed by subduction, probably during the Cretaceous. The northern limb of the Angayucham terrane, which lies between the Brooks Range and the Yukon-Koyukuk province, may contain remnants of the now-closed ocean basin.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB093iB10p11735","issn":"01480227","usgsCitation":"Hillhouse, J.W., and Grommé, C., 1988, Early Cretaceous paleolatitude of the Yukon-Koyukuk province, Alaska: Journal of Geophysical Research Solid Earth, v. 93, no.

Hydrothermal alteration of wall rocks and deposition of sulfide and gangue minerals were contemporaneous with Late Devonian or Early Mississippian basalt-rhyolite volcanism. Whole-rock analyses of altered rocks surrounding the prospect indicate that strong chemical gradients exist in major and minor oxides and volatiles. These were not homogenized or overprinted by Late Jurassic (?) to Middle Cretaceous greenschist to glaucophane-schist facies metamorphism. Very low alkali contents and moderate to very high contents of Ba, F, and Mg are the major chemical characteristics of the pervasively altered rocks. The strong Mg metasomatism, high Ba contents, and limited extent of altered rocks suggest a rapid influx of relatively cold seawater into a hot hydrothermal vent system. Alteration developed asymmetrically around a linear fissure, suggesting fracture control of ore fluids rather than a point source. Micro-probe analyses of phyllosilicates from the Arctic area indicate two discrete mineral populations. Magnesian chlorite, barian white mica, and barian fiuorphlogopite in hydrothermally altered rocks have compositions distinct from similar minerals (chlorite, phengite, biotite) developed during high-pressure metamorphism in metapelitic and metavolcanic lithologies. These differences in mineral chemistry are the result of differences in protolith composition caused by hydrothermal alteration-metasomatism. Without mineral composition data, the contacts between some alteration assemblages and relatively unaltered metavolcanic and metasedimentary rocks with similar mineralogy cannot be determined.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.83.4.822","issn":"03610128","usgsCitation":"Schmidt, J., 1988, Mineral and whole-rock compositions of seawater-dominated hydrothermal alteration at the Arctic volcanogenic massive sulfide prospect, Alaska: Economic Geology, v. 83, no. 4, p. 822-842, https://doi.org/10.2113/gsecongeo.83.4.822.","productDescription":"21 p.","startPage":"822","endPage":"842","numberOfPages":"21","costCenters":[],"links":[{"id":225248,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"83","issue":"4","noUsgsAuthors":false,"publicationDate":"1988-07-01","publicationStatus":"PW","scienceBaseUri":"505a5763e4b0c8380cd6dc44","contributors":{"authors":[{"text":"Schmidt, J.M.","contributorId":97916,"corporation":false,"usgs":true,"family":"Schmidt","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":368227,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The overall deformation is roughly approximated by a 0.24±0.03 µstrain/yr N32°W±2.4° uniaxial contraction that is uniform in time. However, the spatial distribution of deformation shows some concentration of convergence in the neighborhood of the Chugach-St. Elias fault and of right-lateral shear across the Contact fault. A simple dislocation model of the plate interaction in the Yakataga gap fits the observed deformation reasonably well but seems to require that the motion of the Pacific plate relative to the North American plate be directed more nearly N36°W than N15°W, the generally accepted direction of relative motion for this location. However, the direction of plate motion inferred from the dislocation model depends upon details of the interaction at the plate boundary that may not have been modeled accurately. A nearby but smaller trilateration network at Icy Bay was surveyed in 1982, 1984, and 1986. This network spans the southwest corner of the rupture zone of the 1979 St. Elias earthquake. The deformation at Icy Bay consists of left-lateral shear across a northeast trending zone. The relation of this deformation to strain accumulation in the Yakataga gap, postseismic relaxation associated with the 1979 earthquake, or rebound from the unloading associated with the rapid recession of the Guyot glacier is not understood.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB093iB05p04731","issn":"01480227","usgsCitation":"Savage, J., and Lisowski, M., 1988, Deformation in the Yakataga seismic gap, Southern Alaska, 1980-1986: Journal of Geophysical Research Solid Earth, v. 93, no.

Coastal engineering projects that aggrade or degrade permafrost will alter the geomorphology and rates of coastal processes by changing coastal stability. Similarly, projects that modify the ice environment (artificial islands) or the coastal configuration (causeways) will cause nature to readjust to the new process regime, resulting in modification of the coast. In this paper the authors describe the coastal geomorphology from Barrow to the Canadian border. In addition, they provide a general outline and extensive references of the major coastal processes operating in this environment that will be useful on coastal environments elsewhere in the Arctic.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Technical Council on Cold Regions Engineering Monograph","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","isbn":"0872626393; 0872626393","usgsCitation":"Barnes, P.W., Rawlinson, S.E., and Reimnitz, E., 1988, Coastal geomorphology of arctic Alaska: Technical Council on Cold Regions Engineering Monograph, p. 3-30.","startPage":"3","endPage":"30","numberOfPages":"28","costCenters":[],"links":[{"id":225774,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f782e4b0c8380cd4cb63","contributors":{"authors":[{"text":"Barnes, Peter W.","contributorId":6042,"corporation":false,"usgs":true,"family":"Barnes","given":"Peter","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":368427,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rawlinson, Stuart E.","contributorId":99708,"corporation":false,"usgs":true,"family":"Rawlinson","given":"Stuart","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":368429,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reimnitz, Erk","contributorId":17963,"corporation":false,"usgs":true,"family":"Reimnitz","given":"Erk","email":"","affiliations":[],"preferred":false,"id":368428,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The basin between the glacier terminus and the terminal moraine (sill depth of about 22 m) responds as an ‘upside down’ estuary with the subglacial discharge of freshwater entering at the bottom of the basin. The intense vertical mixing caused by the bouyant plume of freshwater creates a homogeneous water mass that exchanges with the far-field water through either a two- or a three-layer flow. In general, the glacier acts as a large heat sink and creates a water mass which is cooler than that in fjords without tidewater glaciers. The predicted retreat of Columbia Glacier would create a 40 km long fjord that has characteristics in common with other fjords in Prince William Sound.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0272-7714(88)90037-6","issn":"02727714","usgsCitation":"Walters, R.A., Josberger, E., and Driedger, C.L., 1988, Columbia Bay, Alaska: An 'upside down' estuary: Estuarine, Coastal and Shelf Science, v. 26, no. 6, p. 607-617, https://doi.org/10.1016/0272-7714(88)90037-6.","productDescription":"11 p.","startPage":"607","endPage":"617","costCenters":[],"links":[{"id":220664,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Columbia Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -147.1703347960633,\n              60.94871704435826\n            ],\n            [\n              -147.03930202977872,\n              60.94517622667948\n            ],\n            [\n              -146.9992047476697,\n              60.95036862872803\n            ],\n            [\n              -146.93504909629522,\n              60.98604346821466\n            ],\n            [\n              -146.9056444227487,\n              61.02685822073474\n            ],\n            [\n              -146.9243564877329,\n              61.04692241618176\n            ],\n            [\n              -146.98858600449472,\n              61.07270649667444\n            ],\n            [\n              -147.00865983779067,\n              61.089580867265994\n            ],\n            [\n              -147.0206890224233,\n              61.115416571124825\n            ],\n            [\n              -146.93381157785387,\n              61.13671514213945\n            ],\n            [\n              -146.9658894035411,\n              61.15735459345197\n            ],\n            [\n              -146.9498504906975,\n              61.1902208362967\n            ],\n            [\n              -147.00999641386096,\n              61.20116863964486\n            ],\n            [\n              -147.05410342418082,\n              61.1857118114151\n            ],\n            [\n              -147.10756646699292,\n              61.170247399055626\n            ],\n            [\n              -147.14900032517224,\n              61.17218086544628\n            ],\n            [\n              -147.21449255261695,\n              61.1902208362967\n            ],\n            [\n              -147.27864820399142,\n              61.180557850104265\n            ],\n            [\n              -147.28132135613197,\n              61.16444628860765\n            ],\n            [\n              -147.22251200903878,\n              61.14510154675949\n            ],\n            [\n              -147.18904686104744,\n              61.12992757515542\n            ],\n            [\n              -147.1275643618137,\n              61.12347359213149\n            ],\n            [\n              -147.12622778574342,\n              61.106041251531394\n            ],\n            [\n              -147.19973946960997,\n              61.113144476736096\n            ],\n            [\n              -147.21043207817232,\n              61.101520186352616\n            ],\n            [\n              -147.1810274046258,\n              61.08859929538238\n            ],\n            [\n              -147.14093012251675,\n              61.084075736681626\n            ],\n            [\n              -147.12622778574342,\n              61.073087259067904\n            ],\n            [\n              -147.11553517718107,\n              61.051745794380025\n            ],\n            [\n              -147.17434452427426,\n              61.04009893443575\n            ],\n            [\n              -147.15563245928993,\n              61.02844779472787\n            ],\n            [\n              -147.1609787635712,\n              60.99735715725802\n            ],\n            [\n              -147.19305658925842,\n              60.988931534822285\n            ],\n            [\n              -147.1703347960633,\n              60.94871704435826\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"26","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f7cae4b0c8380cd4ccdf","contributors":{"authors":[{"text":"Walters, R.
