The R/V Hero, the National Science Foundation research ship, left Punta Arenas on December 12, 1972, dropped off a glaciological party at Deception Island on the 16th, and arrived at Palmer on the 18th. She worked near Palmer until December 25, then went to King George, Deception, and Livingston Islands. At King George, four U.S. passengers transferred to the Chilean ship Piloto Pardo for transit to Punta Arenas; Hero returned to Palmer on December 30.
After 6 days of local operations, Hero began 3 days of trawling that took her as far north as the South Shetlands. At Discovery Bay, four Argentine biologists joined the ship for transit to Palmer; Hero arrived at the station on January 12.
After a January 17 to 20 run to Deception Island to transfer researchers to Livingston Island, the trawler kept busy near Palmer until January 27, when she again sailed to Deception Island to embark homeward-bound researchers and scientific samples. She continued on to Ushuaia, Argentina, her new South American port, arriving there on February 1.
