Abstract

Normandeau Associates, Inc., and APEM Inc. (Team) have
been contracted by BOEM to complete quarterly high-
altitude aerial digital surveys in a 12-month period. The
Team proposes to conduct the first survey in February
2018 and complete all four surveys in the 2018 calendar
year.
The South Atlantic Survey area (SASA) is defined as the
area of the ocean off the coast of North and South
Carolina out to the -30-m contour line. The approximate
size of the area is 11,000 square nautical miles.
Transect surveys will cover a minimum of 5% of the SASA.
In addition, 10% of the total area within the Kitty Hawk,
Wilmington East, and Wilmington West Wind Energy Areas –
as well as the South Carolina–Grand Stand Call Area will
be surveyed.
The planned image resolution of all the imagery for the
project will be 1.5-cm ground sampling distance at the
surface of the ocean.

Option Year 1 includes four surveys of each these areas
from Jan/Feb 2018 to Dec 2018.

Supplemental information

The areas defined for survey were the South Atlantic
Survey Area (SASA), Kitty Hawk (KH) Wind Energy Area
(WEA), Wilmington East (WE) WEA, Wilmington West (WW)
WEA, Grand Stand Call Area (GSCA), Charleston Call Area
(CCA), and fish spawning areas SMZ 51 (A51) and SMZ 53
(A53). SASA surveys are linear transects flown in a saw
tooth pattern out to the -30-m contour line along the
entire South Carolina and North Carolina coasts. These
surveys included the CCA, A51 and A53 areas. The overlap
portion of SASA and CCA is designated “SASA,CCA”; the
overlap portion of SASA and A51 is designated “SASA,A51”;
and the overlap portion of SASA and A53 is designated
“SASA,A53”.The WEAs and GSCA areas are grid surveys
through the area plus a 1NM buffer. GSCA and WW share
survey overlap and that overlap portion is designated as
“GSCA,WW”.The SASA survey area overlaps portions of CCA,
A51 and A53 areas and overlapped areas are designated by
the area name “SASA,CCA”; “SASA,A51”; or “SASA,A53”. GSCA
and WW also share survey overlap and that area is
designated by “GSCA,WW”.DISCLAIMERStudy concept,
