Topographic Wetness Index raster - Land Cover Mapping, North Slope of the Arctic National Wildlife Refuge, Alaska, 2019

"We obtained the 5 m Interferometric Synthetic Aperture Radar Digital Terrain Model (IFSAR DTM) tiles for the study area from https://elevation.alaska.gov/ and mosaicked the products into a single image. We aggregated the DTM to 30 m resolution to represent a more generalized landscape level, and also to allow fairly rapid calculation of more processing-intensive terrain metrics. We then calculated the Sage Topographic Wetness Index at 30 m resolution. This integrates the local slope and the upstream contributing terrain in a continuous metric representing the potential wetness. 

The 'SAGA Wetness Index' is, as the name says, similar to the 'Topographic Wetness Index' (TWI), but it is based on a modified catchment area calculation ('Modified Catchment Area'), which does not think of the flow as very thin film. As result it predicts for cells situated in valley floors with a small vertical distance to a channel a more realistic, higher potential soil moisture compared to the standard TWI calculation."

Fractional Snow Covered Area raster - Land Cover Mapping, North Slope of the Arctic National Wildlife Refuge, Alaska, 2019

We compiled the Landsat Level-3 Fractional Snow Covered Area (fSCA) product (Painter et al. 2009, Selkowitz et al. 2017) for the tiles intersecting the study area for 2000–2017. The product estimates fractional snow cover for each 30-m pixel, with possible values of 0% and 15–100%. We masked all data that was not “Clear” (pixel value of 0) in the Revised Cloud Mask layer. Then we calculated the median snow cover for bimonthly periods from all the Landsat imagery for the period (e.g.,all images for 1–15 May, 2000–2017). We assigned the median snow cover fraction to the midpoint of the period (e.g., 8 May). Then we interpolated to a daily time step (e.g., a pixel that was 80% snow covered on 23 April and 20% snow covered on 8 May was estimated to 50% on 1 May). Finally, we stacked the daily observations, and extracted the last date with ≥15% snow cover as the “last snow day.”

Dynamic Surface Water Extent rasters - Land Cover Mapping, North Slope of the Arctic National Wildlife Refuge, Alaska, 2019

We prepared a water phenology product from the Landsat Level-3 Dynamic Surface Water Extent (DSWE) science product, which provides a water classification for each Landsat scene at 30 m resolution (Jones 2015, Jones 2019). After masking clouds, cloud shadows, and snow, the DSWE product identities 4 categories of water confidence:
1. Not Water;
2. Open Water, High Confidence;
3. Open Water, Moderate Confidence;
4. Partial Surface Water, Conservative; and
5. Partial Surface Water, Aggressive.
We reviewed and summarized the DSWE products for 1999–2018 and prepared two metrics of surface water occurrence (defined as the percentage of the observations when surface water was present):
1. June/July/August, 1999–2018, Conservative Surface Water Occurrence (treating the Partial Surface Water, Aggressive class as Not Water); and
2. June/July/August, 1999–2018, Aggressive Surface Water Occurrence (treating all 4 categories of water confidence as Water).

GOAMAPPS Air Effort

This product represents the survey effort for 2018-2020 Gulf of America Marine Assessment Program for Protected Species surveys and the subsequent 2022-2023 U.S. Fish and Wildlife aerial surveys in the northern Gulf of America.

If a transect was not flown, it is absent for the corresponding survey period. This data view is important and can be used along with air all observations to infer zero value transects, by species or species group.  
 
This seabird survey in the northern Gulf of America was conducted as part of the Bureau of Energy Management’s Gulf of America Marine Assessment Project for Protected Species (GoAMAPPS: 2017-2020), with additional surveys supported by the U.S. Fish and Wildlife Service (USFWS; 2022-2023). Surveys were conducted during January and February (2018, 2019, 2020, 2023) and July (2018, 2022) based on lessons learned from a pilot-effort in July of 2017.  All surveys were conducted from USFWS Quest Kodiak amphibious aircraft at 200 feet AGL from the USA-Mexico border near Brownsville, TX to Key West, FL including the Dry Tortugas.  Surveys extended from the shoreline out to 50 miles for 2018-2020 and were subsequently extended to 100 miles offshore in 2022 and 2023.  Using the US Environmental Protection Agency Environmental Monitoring and Assessment Program’s 40 sq km hexagon sampling grid and a generalized random tessellation stratified sampling technique, we drew a random sample of 180 hexagons to survey in 2018-2020. In 2022 and 2023 and additional 20-hegaons were selected within the BOEM Wind Energy Planning Area. We then selected a random flight direction for each hexagon, which defined two additional, adjacent hexagons thereby increasing the spatial coverage and creating a three-hexagon sampling unit. Each sampling unit consists of three parallel 10 mile transects spaced 1 mile apart, resulting in approximately 30 mile of transect per sampling unit.
