Microzooplankton herbivory in the Ross Sea, Antarctica
Microplankton abundances and phytoplankton mortality rates were determined at six stations during four cruises spanning three seasons in the Ross Sea polynya, Antarctica (early spring, Oct.}Nov. 1996; mid-late summer, Jan.}Feb. 1997; fall, Apr. 1997; mid-late spring, Nov.}Dec. 1997). Rates of microzooplankton herbivory were measured using a modi"ed dilution technique, as well as by examining th...
متن کاملAlbedo of summer snow on sea ice, Ross Sea, Antarctica
[1] Surface all-wave albedo and physical parameters (grain radius, mass density, surface temperature, and stratification) of an austral summer snow cover on sea ice were measured in the Ross Sea during January-February 1999. It was observed that (1) from north to south the snow surface temperature decreases, albedo increases, snow mass density decreases, snow composite grain radius decreases, a...
متن کاملUnnatural Selection of Antarctic Toothfish in the Ross Sea, Antarctica
Historically, fishermen targeted fish in shallow, nearshore waters relatively close to port (Pauly et al. 2005). As these species became depleted, to meet growing demands, fishermen were forced to move offshore and into deeper waters (Hutchings and Reynolds 2004; Koslow et al. 2000; Morato et al. 2006; Hilborn et al. 2003; Pauly et al. 2002, 2005). Steady advances in fishing technology facilita...
متن کاملSummer Epiphytic Diatoms from Terra Nova Bay and Cape Evans (Ross Sea, Antarctica)--A Synthesis and Final Conclusions.
Despite recent advances in polar marine biology and related fields, many aspects of the ecological interactions that are crucial for the functioning of Antarctic shallow water habitats remain poorly understood. Although epiphytic diatoms play an essential role in the Antarctic marine food web, basic information regarding their ecology, biodiversity and biogeography is largely unavailable. Here,...
متن کاملDiversity and Distribution of Deep-Sea Shrimps in the Ross Sea Region of Antarctica
Although decapod crustaceans are widespread in the oceans, only Natantia (shrimps) are common in the Antarctic. Because remoteness, depth and ice cover restrict sampling in the South Ocean, species distribution modelling is a useful tool for evaluating distributions. We used physical specimen and towed camera data to describe the diversity and distribution of shrimps in the Ross Sea region of A...
