MONITORING

BEACH MONITORING

The primary purpose of beach monitoring is to use objective measurements obtained from beach and inshore surveys to track changes over time. Approximately 110 profile locations were established and surveyed in 1999, and serve as a baseline condition for assessing beach conditions along Bogue Banks and were also utilized to form the strategy for the locally-funded Bogue Banks Restoration Project (Phases I, II, and III). A profile is simply a shore perpendicular line where elevations are measured to capture the dune, beach, and offshore environments. The monitoring network has been augmented by 10 additional profiles since 1999 for a total of 120 along Bogue Banks. In 2005, Shackleford Banks, which encompasses a portion of the Cape Lookout National Seashore, and Bear Island (Hammock's Beach State Park) was added to the surveying regime to gain a better understanding of coastal dynamics on a regional scale.

Data obtained during monitoring surveys are used to calculate spatial changes of key landscape features over time, such as the toe of the dune, mean high water line, mean sea level, and the mean low water line. The surveys also plays an important role in quantifying the condition of the beach by measuring volumetric rates of erosion and accretion, confirming sediment volumes added by beach nourishment, tracks the movement of sand in the alongshore and cross-shore directions by comparative surveys, and compares beach conditions from one reach to another. Some of the key landscape features and volumetric boundaries are depicted in the figures below.

Monitoring events are conducted on an annual basis, meaning that the profiles established along Bogue Banks, Shackleford Banks, and Bear Island are revisited once every year. Annual reports that summarize the key aspects of the surveys are presented to the Beach Commission on an annual basis. Electronic versions of these annual reports and other relevant monitoring reports are available below.

SEA TURTLE MONITORING

            The North Carolina Sea Turtle Protection Project is administered by the N.C. Wildlife Resource Commission’s (NCWRC’s) Wildlife Diversity Program and contributes to ongoing sea turtle nest management and protection projects on all of the state's beaches.  Loggerheads, green turtles, leatherbacks and rarely Kemp’s ridleys sea turtle nests have been recorded on North Carolina beaches - the most common nesting species by far is the loggerhead (Caretta caretta).  Nesting surveys and nest protection measures in the State are administered by a variety of public agencies such as the U.S. National Park Service, U.S. Fish & Wildlife Service, U.S. Marine Corps, U. S. Army Corps of Engineers, North Carolina Division of Parks and Recreation, and the University of North Carolina - Wilmington.  Several private organizations and numerous volunteers are also actively involved with sea turtle protection work, including some very robust volunteer efforts along Bogue Banks. The data obtained from nesting surveys are utilized to monitor populations, formulate protective regulations, make management decisions, and maximize reproduction. 

 

If you see turtle nests that are unmarked, stranded sea turtles, evidence of nest disturbances, or other endangered or threatened wildlife, then please call 252-247-8117 and leave a number where you can be reached. Local authorities (police, beach patrol, park personnel) can also be of assistance as can the various volunteer groups.

 

Permit stipulations for the three-phased Bogue Banks Restoration Project constructed in the mid-2000s included its own distinct nesting monitoring program that was administered by the NCWRC as well.  The complete suite of reports for this six-year effort (2002-07) and a summary sheet for the 1996-2012 nesting seasons are available below.
