Alaska North Slope LiDAR

High-resolution light detection and ranging (lidar) elevation data were acquired along the north coast of Alaska between 2009 and 2012. The lidar acquisition, from Icy Cape, Alaska to the United States/Canadian border, comprised approximately 11,000 km2. The airborne lidar data were acquired in support of the U.S. Geological Survey Coastal and Marine Geology Program. The purpose of this lidar...

Using Video Imagery to Study Coastal Change: Barter Island, Alaska

For a short study period, two video cameras overlooked the coast from atop the coastal bluff of Barter Island in northern Alaska. The purpose was to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

Benthic habitat map of the geomorphological structure, biological cover, and geologic zonation of Olowalu reef, Maui Benthic habitat map of the geomorphological structure, biological cover, and geologic zonation of Olowalu reef, Maui

This shapefile contains habitat polygons identifying the dominant and major geomorphological structure, biological type and percent cover, and geologic zone for 11 square kilometers of Olowalu reef off west-central Maui at a minimum mapping unit of 100 square meters. Habitats were mapped with heads-up digitization using the NOAA Habitat Digitizer Extension in ArcMap (Esri, v.10.8.2)...

Nearshore wave time-series along the coast of Alaska computed with a numerical wave model Nearshore wave time-series along the coast of Alaska computed with a numerical wave model

Alaska's Arctic coast has some of the highest erosion rates in the world. Erosion in the Arctic is primarily driven by permafrost thaw and wave activity. The warming climate decreases sea ice coverage, resulting in an increase in wave energy. To overcome the lack of available observational wave data in the nearshore, waves were downscaled with a numerical wave model (SWAN) utilizing...

Historical shorelines and morphological metrics for barrier islands and spits along the north coast of Alaska between Cape Beaufort and the U.S.-Canadian border, 1947 to 2019 Historical shorelines and morphological metrics for barrier islands and spits along the north coast of Alaska between Cape Beaufort and the U.S.-Canadian border, 1947 to 2019

A suite of morphological metrics were derived from existing shoreline and elevation datasets for barrier islands and spits located along the north-slope coast of Alaska between Cape Beaufort and the U.S.-Canadian border. This dataset includes barrier shorelines and polygons attributed with morphological metrics from five time periods: 1950s, 1980s, 2000s, 2010s, and 2020s.

Nearshore bathymetric changes along the Alaska Beaufort Sea coast and possible physical drivers Nearshore bathymetric changes along the Alaska Beaufort Sea coast and possible physical drivers

Erosion rates along Alaska's Beaufort Sea coast, among the highest in the world, are negatively impacting communities, industrial and military infrastructure, and wildlife habitat. Decreasing maximal winter ice extent and increasing summer open water duration and extent in the Beaufort Sea may be making the coast more vulnerable to destructive storm waves than during recent, colder...

Drivers, dynamics and impacts of changing Arctic coasts Drivers, dynamics and impacts of changing Arctic coasts

Arctic coasts are vulnerable to the effects of climate change, including rising sea levels and the loss of permafrost, sea ice and glaciers. Assessing the influence of anthropogenic warming on Arctic coastal dynamics, however, is challenged by the limited availability of observational, oceanographic and environmental data. Yet, with the majority of permafrost coasts being erosive...

Seven decades of coastal change at Barter Island, Alaska: Exploring the importance of waves and temperature on erosion of coastal permafrost bluffs Seven decades of coastal change at Barter Island, Alaska: Exploring the importance of waves and temperature on erosion of coastal permafrost bluffs

Observational data of coastal change over much of the Arctic are limited largely due to its immensity, remoteness, harsh environment, and restricted periods of sunlight and ice-free conditions. Barter Island, Alaska, is one of the few locations where an extensive, observational dataset exists, which enables a detailed assessment of the trends and patterns of coastal change over decadal...

Assessment of barrier island morphological change in northern Alaska Assessment of barrier island morphological change in northern Alaska

Arctic barriers islands are highly dynamic features influenced by a variety of oceanographic, geologic, and environmental factors. Many Alaskan barrier islands and spits serve as habitat and protection for native species, as well as shelter the coast from waves and storms that cause flooding and degradation of coastal villages. This study summarizes changes to barrier morphology in time...

The value of US coral reefs for flood risk reduction The value of US coral reefs for flood risk reduction

Habitats, such as coral reefs, can mitigate increasing flood damages through coastal protection services. We provide a fine-scale, national valuation of the flood risk reduction benefits of coral habitats to people, property, economies and infrastructure. Across 3,100 km of US coastline, the top-most 1 m of coral reefs prevents the 100-yr flood from growing by 23% (113 km2), avoiding...
