A Wiki article has a brief summary of the seaward part of the operation;
Atlantic and Pacific Barrier
The DEW line was supplemented by two "barrier" forces in the Atlantic and the Pacific Oceans which were operated by the United States Navy from 1956 to 1965. These barrier forces consisted of surface picket stations, dubbed "Texas Towers", a surface naval force of twelve radar picket destroyer escorts and sixteen Guardian-class radar picket ships, and an air wing of Lockheed WV-2 Warning Star aircraft that patrolled the picket lines at 1,000–2,000 m (3,000–6,000 ft) altitude in 12- to 14-hour missions. Their objective was to extend early warning coverage against surprise Soviet bomber and missile attack as an extension of the DEW Line.
The Atlantic Barrier (BarLant) consisted of two rotating squadrons, one based at Naval Station Argentia, Newfoundland, to fly orbits to the Azores and back; and the other at NAS Patuxent River, Maryland. BarLant began operations on 1 July 1956, and flew continuous coverage until early 1965, when the barrier was shifted to cover the approaches between Greenland, Iceland, and the United Kingdom (GIUK barrier). Aircraft from Argentia were staged through NAS Keflavik, Iceland, to extend coverage times.
The Pacific Barrier (BarPac) began operations with one squadron operating from NAS Barbers Point, Hawaii, and a forward refueling base at Naval Station Midway, on 1 July 1958. Planes flew from Midway Island to Adak Island (in the Aleutian Island chain) and back, non-stop. Its orbits overlapped the radar picket stations of the ships of Escort Squadron Seven (CORTRON SEVEN), from roughly Kodiak Island to Midway and Escort Squadron Five (CORTRON FIVE), from Pearl Harbor to northern Pacific waters. Normally 4 or 5 WV-2s were required at any single time to provide coverage over the entire line.
The Guardian-class radar picket ships were based in Rhode Island and San Francisco, and covered picket stations 400–500 miles off each coast.
Barrier Force operations were discontinued by September 1965 and their EC-121K (WV-2 before 1962) aircraft placed in storage.
This article written by Capt. Joseph F. Bouchard, U.S. Navy for the Naval War College, has a better summary. But, still doesn't include a listing of all the DER units.

Dr Friedman writes about the DEW line "ocean extension" Radar Pickets in his Destroyers Design book. One of my uncles served during WWII onboard one of the first six units converted to DER in the early 1950s. Various issues of Jane's and Fahey SHIPS and AIRCRAFT issues have listing of the DER units involved.
The seven WWII converted DE Radar Pickets were intended as a sort of smaller GEARING DDR. Instead of operating with the carrier Task Forces, the DER conversation would be assigned as operating off-shore at invasion locations. Likely intended for the planned invasion of Japan.
