79.1 Methods
79.1.1 Data sources
BOEM lease areas: https://www.boem.gov/renewable-energy/mapping-and-data/renewable-energy-gis-data BOEM lease construction status: https://www.boem.gov/renewable-energy/offshore-renewable-activities NOAA ENC - Turbine Foundation Locations: https://www.nauticalcharts.noaa.gov/charts/noaa-enc.html
79.1.2 Data analysis
Lease area acreage was obtained from the ‘Acres’ column of the attribute table in the Bureau of Ocean Energy Management’s (BOEM) ArcGIS Online (AGOL) hosted feature service, “Wind Lease Boundaries BOEM - Offshore Wind Lease Outlines”. To the extent possible, acreage values were verified against official lease documents. In the event of a discrepancy or missing data, the acreage reported in the official lease document was used (see Table 1). Note that a single lease area may comprise multiple projects (for example, the Empire Wind lease area comprises the Empire Wind 1 and Empire Wind 2 projects).
Table 1: List of discrepancies or missing acreage data between the BOEM hosted feature service and official lease documents.
| Lease Number | Hosted Feature Service Acreage | Lease Document Acreage |
|---|---|---|
| OCS-A 0486 | 83,789 | 83,798 |
| OCS-A 0520 | 128,881 | 128,811 |
| OCS-A 0534 | NA (missing) | 52,663 |
| OCS-A 0561 | NA (missing) | 48,927 |
| OCS-A 0570 | 43,439 | 43,412 |
Turbine Foundations The number of turbine foundations in each lease area, either proposed or installed, was tallied using the NOAA Electronic Navigational Charts (ENCs).
79.1.3 Data processing
Data were formatted for inclusion in the ecodata R package using the R code found here.
