Summary for Field Activity Number 1977-009-FA

Alternate Leg ID: Legs I, II, III, and IV

Area of Operations: Georges Bank, Great South Channel, New Jersey continental shelf, United States, North America, North Atlantic

Dates: Mar 08, 1977 to April 17, 1977

Objectives: The WHITEFOOT cruises were conducted to recover and deploy oceanographic instrumentation on Georges Bank and on the New Jersey continental shelf. Due to severe winter weather and problems encountered in recovering instrumentation, four trips were required to complete the necessary work. Objectives were to: recover (#120) and deploy (#126) one tripod on Georges Bank; recover ARGO MERCHANT current meter array (moorings #123, 124 and 125); recover one tripod (#121) and surface buoy in Great South Channel (part of ARGO MERCHANT array); recover (#119) and deploy one tripod (#122) off New Jersey; and make XBT observations to determine temperature structure in the vicinity of current and tripod moorings.

Type of Activity: Mooring work

Information to be derived: Time series data

Summary: This cruise was conducted in four legs due to weather constraints. Leg I: March 8-11, 1977; Leg II: March 14-20, 1977; Leg III: March 31 - April 5, 1977; Leg IV: April 15-17, 1977. Moorings recovered: 6 (#119 and 120 both deployed FA 76047 OCEANUS 17 Dec. 3-10, 1976; #121 and 123 both deployed FA 76048 WHITEFOOT Dec. 22-29, 1976; and #124 and 125 both deployed FA 76049 OCEANUS 20 Dec. 28-29, 1976). Moorings deployed: 2 (#122 and 126 both recovered FA 77023 OCEANUS 29 Jul. 6-13, 1977). XBTs: 41; Surface salinity samples: 41.
