Unnatural 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 کاملVegetation synchronously leans upslope as climate warms.
E cologists have long sought to understand how vegetation relates to climate (1, 2). Such knowledge underlies effective mitigation and adaptation to contemporary climate change (3). Warming temperatures associated with anthropogenic increases in greenhouse gases have led ecologists to predict that vegetation gradients will ‘‘march’’ up the hill as climate envelopes shift with elevation, at a la...
متن کاملIncrease of the Antarctic Sea Ice Extent is highly significant only in the Ross Sea
In the context of global warming, the question of why Antarctic sea ice extent (SIE) has increased is one of the most fundamental unsolved mysteries. Although many mechanisms have been proposed, it is still unclear whether the increasing trend is anthropogenically originated or only caused by internal natural variability. In this study, we employ a new method where the underlying natural persis...
متن کاملHigh-frequency observations of pH under Antarctic sea ice in the southern Ross Sea
Although predictions suggest that ocean acidification will significantly impact polar oceans within 20–30 years, there is limited information regarding present-day pH dynamics of the Southern Ocean. Here, we present novel high-frequency observations of pH collected during spring of 2010 using SeaFET pH sensors at three locations under fast sea ice in the southern Ross Sea. During these deployme...
متن کاملResilience of the Present Climate to Antarctic Sea-Ice Loss
The role played by Southern Hemisphere sea-ice in global climate is explored using an Earth system climate model of intermediate complexity. An ensemble of experiments is analysed where freshwater forcing equivalent to a complete 100 year meltback of Southern Hemisphere sea-ice is applied to a model run that simulates the present climate. This freshwater forcing acts to mildy subdue Southern Oc...
