flowing SE into Mercator Ice Piedmont, Bowman Coast, and separated by a col at c. 1050m from Neny Glacier (q.v.), which flows NW into Neny Fjord, Fallières Coast, was seen from the air by USAS, 21 May 1940. The name Neny Trough was applied to that part of the through valley (occupied by the two glaciers) which was not visible from Neny Fjord (USHO, 1943, p.272; Black, 1945, p.5, 11). In January 1941 the valley was traversed by a USAS sledge party and referred to as Neny Valley (Ronne, 1945, p.20). The name Neny Trough was later applied to the whole feature between Neny Fjord and Mercator Ice Piedmont (Ronne, 1948b, p.367; APC, 1955, p.15). Neny-Breen, Neny-Passet, Neny-Traktene, referring to the whole valley (Rønne, 1950b, p.61, 102, 111). Neny Glacier, apparently referring to the whole valley (Nichols, 1953, Fig. 2, p.3). Following survey by FIDS from "Stonington Island" in 1958, the name Neny Glacier was restricted to the NW glacier and the present feature, the SE glacier, was named Gibbs Glacier after Peter McCausland Gibbs (b.1934), FIDS surveyor, "Horseshoe Island", 1957-58, and Base Leader and surveyor, "Stonington Island", 1958-59, who surveyed the glacier (APC, 1962, p.14; DOS 610 sheets W 68 64 and 68 66, 1963).

A glacier, 15 mi long, flowing SE into the N part of Mercator Ice Piedmont on the E side of Antarctic Peninsula. This feature together with Neny Glacier, which flows NW, occupy a transverse depression between Mercator Ice Piedmont and Neny Fjord on the W side of Antarctic Peninsula. Gibbs Glacier was photographed from the air and first mapped by the USAS, 1939-41, and RARE, 1947-48. Named by UK-APC for Peter M. Gibbs of FIDS, surveyor at Horseshoe Island, 1957, and leader at Stonington Island, 1958, who was responsible (with P. Forster) for the first ground survey of the glacier.
