79.1 Methods

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.

Turbine Foundations The number of turbine foundations in each lease area, either proposed or installed, was tallied using the NOAA Electronic Navigational Charts (ENCs).
