# R/V ROGER REVELLE

The *R/V Roger Revelle*, operated by the Scripps Institution of
Oceanography, conducted four cruises (RR06 through RR09) in Antarctic
waters on behalf of the U.S. JGOFS Antarctic Environment and Southern
Ocean Process Study (AESOPS). Research was conducted on the physical,
chemical, and biological influences affecting the phytoplankton bloom,
the temporal variability of blooms, and the apparent paradox of high
fluxes of biogenic material to the sea bed in a region of low mean
annual primary production. Cruises, for the most part, took place along
a section at 170°W, between October, 1997 and March, 1998.

## RR06: AESOPS Spring Survey-I October 20, 1997 - November 24, 1997

Timothy J. Cowles, Oregon State University, Chief Scientist

The primary objective of the first cruise was to provide mesoscale
resolution of the physical, chemical, and biological properties in and
around the Antarctic Polar Front. Stations, moorings, drifters and
SeaSoar surveys were combined with concurrent underway surface
measurements to collect data on these properties and processes.

The purpose of the Process-I cruise was to characterize the
biogeochemical processes between 53°S and the edge of the pack ice,
located at roughly 64°40\'S. Twelve (12) long stations were completed
along the U.S. JGOFS 170°W transect, as well as, an intensive
six-station section across a subsurface temperature front at 60°50\'S in
the polar frontal zone. Station work began at 53°S, 174°W on Dec. 5th
and proceeded southward toward the pack ice and arriving at the seventh
station at 64°09\'S, 169°30\'W on Dec. 17th.

## RR08: AESOPS Survey-II (Summer Survey) January 8, 1998 - February 8, 1998

Kenneth Coale, Moss Landing Marine Lab, Chief Scientist

Research objectives of the Survey-II cruise were much like those of
Survey-I, although ice images that arrived Jan. 16th showed the edge of
the sea ice at about 69°30\'S along 170°W, so the ice would not restrict
access to the AESOPS study area as it had during Survey-I. The *R/V
Roger Revelle* steamed south from 57°S, towing the Oregon State
University (OSU) SeaSoar and constructing real-time vertical
cross-sections of temperature, salinity, density, large particle
concentrations and a number of fluorescence parameters. In addition,
underway surface water measurements of nutrients, the partial pressure
of carbon dioxide (pCO2), metals, oxygen, salinity, phytoplankton
species and abundance, chlorophyll, silicate uptake, dissolved organic
carbon, fluorescence, currents and the meteorological parameters
complimented the acquisition of SeaSoar data.

## RR09: AESOPS Process Study-II February 13, 1998 - March 19, 1998

Wilford D. Gardner, Texas A&M University, Chief Scientist

The final AESOPS Antarctic Polar Frontal Zone (APFZ) cruise left
Lyttelton, New Zealand, on Feb. 13, 1998. The purposes of the cruise
were to characterize fall biogeochemical processes from north to south
of the APFZ along the 170°W transect, to determine whether the bloom had
continued southward, and to compare pre-bloom, post-bloom and full bloom
conditions, if possible.

# R/V YUZHMORGEOLOGIYA

The *R/V Yuzhmorgeologiya* was charted by the National Oceanic
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 early April 1998. A large-area
survey was conducted on Leg I and again on Leg II, while 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" dominated the
area north of Livingston island, which included new AMLR stations;
"Bransfield Strait water" and transitional water were identified on the
South Shetland continental slope and shelf.

1997/98 was the first full season of seabird research at Cape Shirreff
and thus comparisons with prior years are not possible. However, based
on mean breeding success from Admiralty Bay, approximately 140
kilometers (km) northeast on King George Island, the chinstrap penguin
population had average and the gentoo penguin population above average
breeding success. Pinniped studies at Cape Shirreff revealed that the
total number of Antarctic Fur seal pups born at the Cape and San Telmo
Islands during the 1997/98 breeding season was 7,748, which is a 14.1%
decrease in pup production from the 1996/97 count of 9,015. At Palmer
Station, 4,412 breeding pairs of Adelie penguins were observed at 54
sample colonies during the peak egg-laying period (24-29 November 1997),
which was essentially unchanged from the number of breeding pairs
(4,445) censused in November 1996. Adelie penguins exhibited a slight
increased breeding success in the 1997/98 season, creching 1.58 chicks
per pair, or 0.11 chicks more than were creched per pair in the 1996/97
season.
