at 0.2-foot intervals, or over the entire 45-foot length of gage with 
recording plugs spaced at 1-foot intervals. It thus gives finer detail 
for the normal smaller waves, but also affords measurement of the very 
large waves associated with higher water levels during severe storms. 
(h) Regional Studies, 
Additional compilations are underway on geomorphological and littoral 
material data for the coastal sector from Cape Henlopen, Delaware, to Cape 
Charles, Virginia. The report on the geomorphology of this area is under 
preparation. 
A comprehensive program was initiated late in FY 1962 to develop 
data on offshore deposits of material along the Atlantic coast that could 
be utilized in beach fill and nourishment projects. The study of the off- 
shore deposits was intended to encompass all factors pertinent to the use 
of such deposits in the beach zone. A pilot study for the offshore pro- 
gram was completed in the Miami Beach - Palm Beach, Florida area during 
August 1962. Comparative profiles and geophysical exploration of the 
shallow sub-bottom strata were studied to locate potential offshore borrow 
. sites. Surface samples of the bottom sediments were obtained by the 
dredge ESSAYONS in the vicinity of Hillsboro Inlet and Bakers Haulover. 
A further pilot study involving sediment core sampling as well as geo- 
physical exploration of the bottom is planned early in FY 1964, probably 
for an area off the middle Atlantic coast. 
(i) Re-examination of Beach Protection Projects. 
A continuing program is being carried out on the re-examination of 
beach fill and periodic nourishment projects to determine the effective- 
ness of the fill material within the beach zones, and to better establish 
the factors upon which the desired characteristics of fill material are 
based, Continuing studies of other projects constructed following Beach 
Erosion Control studies are also underway to determine effectiveness of 
various structure components. In particular data have been obtained on 
behavior of fill placed at Seaside Park and Sherwood Island State Park, 
Connecticut, and at Key West, Florida. These data are being compiled and 
a report is under preparation. 
Over the past 25 years many ground level photographs have been taken 
of beaches on the New Jersey coasts. This photographic data has been 
brought up to date as of 1962, and a pictorial history type report is 
essentially completed. 
Data collection program has also been carried out at the Port Mans- 
field, Texas, entrance channel. The navigation project at Port Mansfield 
involves a jettied entrance with a channel cut through the offshore barrier 
(Padre Island) into Laguna Madre and on to Port Mansfield. The data col- 
lection program involves both shoaling and tidal data. Tidal elevations
