R/V YUZHMORGEOLOGIYA

The R/V Yuzhmorgeologiyawas chartered for the fourth consecutive year by the National Oceanic and Atmospheric Administration, National Marine Fisheries Service to support activities of the U.S. Antarctic Marine Living Resources (AMLR) field research program. Shipboard surveys were conducted on three legs in the AMLR study area between early January and late March 1999.  A large- area survey was conducted on Leg I and again on Leg II; Leg III was dedicated to a bottom trawl survey.  Two major water zones were observed during the surveys on Legs I and II:  “Drake Passage water” (Water Zone I) and “Bransfield Strait water” (Water Zone IV).  Water Zone I dominated the area northwest of Livingston and King George Islands, which included new ALMR stations.  A prevailing southwest to northeast flow was observed across the AMLR study area, with an eddy-like feature northwest of Elephant Island.

This was the second full season of seabird research at Cape Shirreff.  The breeding populations of chinstrap and gentoo penguins this season were determined to be 7581 chinstrap penguin pairs and 830 gentoo penguin pairs.  This represents a slight change from the 1997/98 seas on when there were 7617 and 810 breeding pairs, respectively.  Reproductive success of chinstrap penguins was higher and gentoo penguins lower in the 1998/99 season than in the previous season.  Penniped studies at Cape Shirreff indicated that Antarctic fur seal pup production increased in 1998/99 over last year.  Return rates for adult female fur seals and yearling pups appeared to indicate good over-winter survival.  At Palmer Station, Adelie penguin breeding success in 1998/99 decreased, with 1.49 chicks creched per pair compared to 1.58 during the 1997/98 season.  Of the 2082 broods censused in January 1999, 61.9% contained two chicks, which was almost no change from the 60.9% report in January 1998.  Chick production totaled 5469 chicks this season, a 4.4% decrease relative to the 5722 chicks reported from these colonies in January and February 1998.
